ChatGPT answers, unedited

Yes. For an educational YouTube channel, you want a tool that does more than give you generic keyword volume—you want to identify topics competitors rank for that you don't cover, especially topics where smaller channels are getting disproportionate views.

My shortlist

• vidiq.com — probably the easiest starting point. It combines keyword research with competitor tracking, “outlier” videos, rising keywords, and channel-specific ideas. Its keyword research includes search-volume and competition estimates. vidIQ vidIQ Help Center
• tubebuddy.com — particularly useful if you want to research a keyword while you're already browsing YouTube. Keyword Explorer provides volume, competition, related terms, and other search-landscape information. TubeBuddy
• semrush.com — worth considering if you want a more explicit competitor/topic-gap analysis, particularly if your educational channel also has a website. Its YouTube keyword product provides search-volume, competitive-rate, related-keyword and fast-growing-search data. vidIQ Semrush
• ahrefs.com — stronger if you want to combine YouTube research with Google/website SEO. It's less YouTube-creator-centric than vidIQ, but useful if your educational content has an accompanying site. vidIQ
• OutlierKit — worth testing if your main objective is finding low-competition opportunities and breakout/outlier videos, rather than general channel management. OutlierKit

What I'd actually do

For your specific goal, I'd start with vidIQ + YouTube Studio.

The workflow is:

1. Pick 5–10 genuinely similar educational channels.
2. Use vidIQ to find their top/outlier videos and the keywords/topics associated with them.
3. Create a spreadsheet of those topics.
4. Remove topics you've already covered.
5. Group the remaining terms into topic gaps rather than treating every keyword separately.
6. Check YouTube autocomplete and the existing search results manually.
7. Prioritize gaps where:

• people clearly search for the concept,
• competing videos aren't dominated exclusively by huge channels,
• your channel has relevant expertise,
• and there's a useful angle you can teach better/differently.

One important caveat: YouTube doesn't publish its actual search-volume numbers, so third-party volume figures should be treated as estimates rather than ground truth. OutlierKit

If you tell me your educational niche + your channel URL + 3–5 competitor channels, I can also lay out a concrete competitor keyword-gap methodology and show you exactly what I'd look for.

Yes. If your goal is specifically “find topics/keywords that similar educational channels are getting traffic from, but my channel isn't covering yet,” I’d look at these:

Best options

• vidiq.com — strongest all-around choice for YouTube competitor research. Its competitor tools let you track channels, inspect top-performing videos, and export competitors’ top keywords. Its keyword research also surfaces search volume, competition, related terms, questions, and rising keywords. vidIQ Help Center vidIQ
• tubebuddy.com — good for keyword opportunity research inside YouTube. Keyword Explorer provides competition, search-demand information, related terms, and optimization guidance. TubeBuddy TubeBuddy
• semrush.com — useful if you also care about Google/search SEO. Its Keyword Gap tool is explicitly designed to compare competitors' keyword profiles and identify keywords they rank for that you don't. Its YouTube Keyword Analytics product also provides YouTube search-demand and competition data. Semrush Semrush
• 1of10.com — worth considering for finding unusually successful videos in your niche. It's more about identifying outlier content opportunities than doing traditional keyword-gap analysis. Semrush

What I'd use for an educational channel

I'd start with vidIQ, because your question is really about competitor → topic → keyword → content gap, rather than conventional website SEO.

For example, suppose you teach biology and have five comparable channels. I'd build a spreadsheet like:

The important distinction is that a keyword gap isn't automatically an opportunity. I'd prioritize topics where:

1. Multiple comparable channels have successful videos.
2. Your channel has little/no coverage.
3. The topic has meaningful search demand.
4. Competition isn't dominated exclusively by huge channels.
5. The topic fits what your existing audience watches.

vidIQ specifically provides competitor keyword exports and top-video analysis that can help construct this workflow. vidIQ

If you tell me your educational niche and give me 3–5 similar YouTube channels, I can also show you exactly how I'd perform the gap analysis and what metrics I'd use.

Yes. If your goal is specifically “What topics/keywords are similar educational YouTube channels getting traffic from that I haven't covered yet?”, there are a few tools worth considering.

Best options

1. vidIQ — probably the closest match

For an educational channel, I'd start here. Its competitor functionality lets you compare your channel with competitors, while its keyword research shows search volume, competition, related keywords and questions. vidIQ Help Center vidIQ Help Center

The useful workflow is:

Your channel → 5–10 similar channels → identify their winning videos → extract recurring topics/keywords → find topics they cover that you don't → prioritize by demand vs. competition.

That's much more useful than simply looking for keywords with high search volume.

support.vidiq.com

2. TubeBuddy

tubebuddy.com is particularly good if you want to determine whether your channel can realistically compete for a keyword, rather than merely finding popular keywords.

Its Keyword Explorer combines keyword data with an opportunity score, while TubeBuddy also has competitor research and SEO tools. vidIQ

I'd choose TubeBuddy over vidIQ if your main question is:

“Which of these keywords can my channel realistically rank for?”

3. Ahrefs — strongest for serious gap analysis

If you're willing to use a more traditional SEO platform, ahrefs.com is powerful.

Its Content Gap tool is specifically designed to find keywords that competitors rank for while your site doesn't, with filters for things like ranking position and keyword difficulty. Ahrefs Help Center

Ahrefs also has a YouTube keyword tool that can generate large sets of related queries and questions. Ahrefs

The catch: Ahrefs is more naturally suited to web/Google SEO than pure YouTube competitor intelligence.

4. Keywords Everywhere

keywordseverywhere.com has an actual Keyword Gap Analysis feature that compares competitors and identifies keywords they rank for that you don't. It can compare up to 10 competitors. Keywords Everywhere

This can be useful if your educational content also lives on a website/blog.

What I'd use for an educational channel

I wouldn't optimize around keywords alone.

I'd build a competitor-gap system like this:

1. Pick 5–10 genuinely similar channels

Not necessarily the biggest channels. Ideally channels that have:

• Similar audience
• Similar subject
• Similar video length
• Similar teaching style
• Slightly larger/similar subscriber count

2. Find their “outlier” videos

For example, if a 40K-subscriber channel has a video with 800K views, that's far more interesting than a video with 50K views.

3. Group those videos into topics

Suppose you're teaching economics and competitors have unexpected winners around:

• inflation explained
• why interest rates matter
• recession indicators
• housing bubbles
• yield curves

You may discover that “economic indicators explained” is an entire content cluster you're under-serving.

4. Then do keyword research

Take those topics into vidIQ/Ahrefs/TubeBuddy and find the specific queries surrounding them.

5. Score each opportunity

I'd use something like:

Opportunity = audience demand × competitor evidence × relevance to your channel ÷ difficulty

That produces a much better editorial calendar than chasing whatever keyword has the highest search volume.

My recommendation

If you're YouTube-first: vidIQ + YouTube Studio.

If you're YouTube + website/Google SEO: Ahrefs + vidIQ.

If you're on a tight budget: start with vidIQ's free functionality, YouTube autocomplete/Studio data, and manually analyze competitor outliers. vidIQ currently offers a free plan with core research features. vidIQ

If you tell me your educational niche + your channel URL + 3–5 competing channels, I can also show you exactly how I'd identify the 10–20 highest-potential content gaps between them.

If you're on a tight budget: start with vidIQ's free functionality, YouTube autocomplete/Studio data, and manually analyze competitor outliers. vidIQ currently offers a free plan with core research features.

The catch: Ahrefs is more naturally suited to web/Google SEO than pure YouTube competitor intelligence.

4. Keywords Everywhere

For an educational YouTube channel, I’d start with vidIQ. It combines keyword opportunity scoring, competitor tracking, trends, and content ideas—useful for finding topics competitors are getting traction from that you haven’t covered. LensPOV CreatiCalc

• vidIQ — best all-around for competitor + keyword gaps.
• OutlierKit — excellent for finding competitor videos that dramatically outperform their channel average, then reverse-engineering those topics. OutlierKit
• TubeBuddy — better if you also want SEO optimization and thumbnail A/B testing. LensPOV
• TubeAI Keyword Gap Analyzer — specifically compares your channel against up to 3 competitors and identifies shared/unique keyword gaps. ValetScript

My stack: vidIQ + OutlierKit. That combination is particularly good for discovering “competitors have proven demand, but nobody is serving this educational angle well” opportunities.

Yes. For an educational YouTube channel, I’d focus on tools that can answer two different questions:

1. What keywords/topics are competitors getting traffic from that I’m not covering?
2. Which of those gaps are actually realistic opportunities for my channel?

Best options

• vidiq.com — my first choice for YouTube specifically.

Its competitor tools let you track other channels, analyze their top-performing videos, and export competitor keyword data. Its keyword research also shows estimated search volume, competition, related keywords, and questions. vidIQ vidIQ Help Center

• tubebuddy.com — strong alternative.

Its Keyword Explorer evaluates search demand/competition and its workflow is tightly integrated with YouTube. It's particularly useful if you want to go from keyword → title → optimization without leaving YouTube. TubeBuddy

• semrush.com — best if your educational channel also targets Google Search.

Its Keyword Gap tool is explicitly designed to compare your keyword profile with competitors and identify keywords they rank for that you don't. The catch is that it's fundamentally a web/Google SEO tool rather than a YouTube-native competitor tool. Semrush

What I'd use for your particular goal

If your channel is primarily YouTube educational content, I'd start with vidIQ.

The workflow I'd use is:

Your channel → 5–10 comparable channels → their top/outlier videos → keywords/topics → remove topics you've already covered → score remaining opportunities by demand × competition × relevance.

The important part is not simply copying competitor keywords. You want to find things like:

Competitors have multiple videos about "AP Biology cellular respiration practice questions", but your channel has no equivalent.

or:

People search "how to solve ___ step by step", competitors have weak/old coverage, and your channel already has authority in the broader subject.

That's a much more actionable content gap than simply finding high-volume keywords.

One important distinction

Don't confuse keyword gaps with content gaps.

A keyword tool might tell you that competitors rank for photosynthesis, but that isn't necessarily an opportunity. A more useful finding could be:

• photosynthesis practice problems
• photosynthesis explained for beginners
• photosynthesis vs cellular respiration
• photosynthesis exam questions
• photosynthesis misconceptions
• photosynthesis lab walkthrough

Those are specific educational intents you can turn into individual videos.

If you tell me your educational niche + your YouTube channel URL + 3–5 competing channels, I can show you exactly how I'd perform the gap analysis and what opportunities I'd look for.

or:

People search "how to solve ___ step by step", competitors have weak/old coverage, and your channel already has authority in the broader subject.

That's a much more actionable content gap than simply finding high-volume keywords.

One important distinction

Don't confuse keyword gaps with content gaps.

Yes. If your goal is specifically “find keywords/topics that similar educational channels are getting views from, but that they’re underserving or missing”, I’d look at these:

Best options

• vidiq.com — Best overall for YouTube competitor + keyword research.

It combines keyword demand, competition, related queries, trends, competitor tracking, and “outlier” videos. That makes it particularly useful for finding topics where a competing channel got unusually strong results and you could create your own version. vidIQ vidIQ

• tubebuddy.com — Best for keyword opportunity scoring.

Its Keyword Explorer/Search Explorer shows search volume, competition, related terms, and keyword scores while you're browsing YouTube. It also incorporates your channel's strength into its opportunity assessment. TubeBuddy TubeBuddy

• semrush.com — Most directly aligned with “content gaps.”

This is unusually close to what you're asking for: it analyzes the top competitors and looks for weaknesses in their videos, including poor engagement and viewer frustrations, then suggests opportunities to make a better competing video. Semrush

• ahrefs.com — Best if your educational channel also has a website.

Ahrefs is stronger for broader Google/SEO keyword research than purely YouTube competitor research. It can help you identify topics with search demand that competitors haven't adequately covered, then translate those into YouTube topics. vidIQ

What I'd use for an educational channel

If I were building the workflow, I'd use:

vidIQ + YouTube Studio + Google Trends

The important thing is not simply finding a keyword with high volume. You're looking for this combination:

High audience demand + weak competitor coverage + realistic ranking difficulty + strong fit with your channel

For example, suppose you're an educational channel about biology and competitors have videos around:

• “Cellular respiration”
• “Krebs cycle”
• “ATP explained”

You might discover searches such as:

• “Krebs cycle explained simply”
• “Krebs cycle mistakes students make”
• “cellular respiration practice questions”
• “ATP vs ADP explained”
• “cellular respiration exam questions”

Those are potentially more valuable than simply targeting “cellular respiration”, because you're identifying specific unanswered viewer intent.

My ranking for your particular use case

YouTube Studio is especially important because it gives you your own actual search-performance data, rather than relying entirely on third-party estimates. vidIQ itself recommends pairing its research with YouTube Studio to validate what actually produces views for your channel. vidIQ

If you tell me your educational niche + 3–5 competing YouTube channels, I can also show you exactly how I'd do a competitor keyword-gap analysis and what gaps I'd look for.

Yes. For an educational YouTube channel, I’d focus less on generic “keyword volume” and more on finding topics your competitors get demand for but you—or the niche as a whole—aren’t serving well.

My top picks

1. vidiq.com — best overall for competitor gaps

• Lets you track competitor channels and identify their top-performing videos.
• Its competitor tools can surface competitor keywords and sort videos by views per hour, which is particularly useful for spotting topics currently outperforming. vidIQ vidIQ
• Particularly good if you want: “What are similar educational channels getting views from that I could make a better version of?”
• Its current positioning is especially strong around trend discovery and competitor analysis. vidIQ
• tubebuddy.com — best for keyword opportunity scoring

• Keyword Explorer gives you search demand, competition, related terms and keyword scores. TubeBuddy
• Its Search Explorer also lets you analyze the channels/videos appearing for a query. TubeBuddy
• I'd choose this if your question is more: “Which specific search terms can my channel realistically rank for?”
• ahrefs.com — best if YouTube + Google matter

• Stronger if your educational channel also has a website, blog, newsletter, or course business.
• Ahrefs supports YouTube keyword research alongside its much broader SEO/competitive-analysis capabilities. vidIQ Ahrefs
• Good for finding opportunities such as “people search for this educational topic on Google, but YouTube coverage is weak.”
• semrush.com — best for broader content-gap research

• Its traditional Keyword Gap functionality is particularly useful if you're comparing websites/domains.
• I'd use it alongside YouTube-specific software rather than as your only YouTube tool.

What I'd use for your specific goal

If your goal is:

“Find educational topics/keywords where competing channels have demonstrated demand, but there is an underserved opportunity for my channel.”

I'd use vidIQ + YouTube Studio, rather than buying five different tools.

A practical workflow:

1. Pick 5–10 genuinely similar channels.

Don't just choose the biggest channels. Include channels roughly 1–10× your size. Their successful videos are more informative about what you could realistically reproduce.

2. Put them into vidIQ's Competitors tool.

Look for videos with unusually high views relative to the channel's normal performance, rather than simply the videos with the most total views. vidIQ specifically provides VPH and outlier-style competitor analysis for this purpose. vidIQ vidIQ

3. Build a “competitor gap” spreadsheet.

For every promising video, record:

The views/subscriber ratio is particularly interesting. A 150K-view video from a 30K-subscriber educational channel is a much stronger signal than a 150K-view video from a 5-million-subscriber channel.

4. Then investigate the actual keyword.

Run the promising topics through TubeBuddy or vidIQ and look for:

• reasonable search demand
• relatively low competition
• related long-tail searches
• questions people ask
• rising/trending variations
• multiple competitors succeeding with the same underlying topic

TubeBuddy, for example, explicitly provides competition, search traffic, related terms and keyword guidance. TubeBuddy

5. Look for the content gap, not just the keyword gap.

This is where educational channels can really win.

Suppose competitors have:

“Photosynthesis Explained”

You might discover underserved variations such as:

• “Photosynthesis explained for beginners”
• “Photosynthesis in 10 minutes”
• “Photosynthesis vs cellular respiration”
• “Photosynthesis explained with animation”
• “Photosynthesis exam questions”
• “Why plants need sunlight”
• “Photosynthesis mistakes students make”

The opportunity isn't necessarily to make another “Photosynthesis Explained.” It's to find the unserved intent around the topic.

If I had to pick only one

Start with vidIQ. Its current competitor functionality is closest to what you're asking for: find what similar channels are succeeding with, identify their keywords/topics, and turn those gaps into ideas. vidIQ

Then use YouTube Studio to validate what your own audience is actually searching for, and optionally TubeBuddy to pressure-test individual keywords.

One caveat: don't treat third-party search-volume numbers as gospel. YouTube doesn't expose perfect public keyword-volume data, and estimates from tools can differ substantially from actual impressions. Ahrefs

If you tell me what your educational channel teaches + roughly how many subscribers you have, I can give you a concrete competitor-gap research workflow and tell you exactly which 5–10 channels and keywords I'd investigate first.

The views/subscriber ratio is particularly interesting. A 150K-view video from a 30K-subscriber educational channel is a much stronger signal than a 150K-view video from a 5-million-subscriber channel.

4. Then investigate the actual keyword.

Run the promising topics through TubeBuddy or vidIQ and look for:

• reasonable search demand
• relatively low competition
• related long-tail searches
• questions people ask
• rising/trending variations
• multiple competitors succeeding with the same underlying topic

TubeBuddy, for example, explicitly provides competition, search traffic, related terms and keyword guidance.

If your goal is specifically to find keyword/topic gaps that educational channels are missing relative to competitors, I’d prioritize YouTube-native tools over traditional SEO software.

Best options

• vidiq.com — best overall for competitor gap hunting. It combines YouTube keyword demand, competition, related queries, rising keywords, competitor research, and “outlier” videos. Its current keyword tools expose search volume, competition, trends, and related terms. vidIQ vidIQ
• tubebuddy.com — best for practical YouTube SEO. Its Search Explorer/Keyword Explorer shows keyword scores, volume, competition, related terms, and information about the videos/channels appearing for a query. TubeBuddy TubeBuddy
• ahrefs.com — best if your educational channel also has a website/blog. Ahrefs is stronger for broader Google SEO and can complement YouTube research, but it isn't as YouTube-centric as vidIQ or TubeBuddy. vidIQ
• semrush.com — best for broader competitor/content-gap analysis. I'd choose it if you're trying to identify gaps across YouTube + Google rather than YouTube alone.

What I'd use for your specific goal

I'd start with vidIQ.

The workflow I'd use is:

1. Enter your channel's main educational topics.
2. Identify 5–15 genuinely comparable channels—not just the biggest channels.
3. Look at their top-performing/outlier videos.
4. Extract the recurring topics and search terms behind those videos.
5. Find terms where: - competitors have videos getting strong views,
6. there are multiple related searches,
7. competition isn't dominated by huge channels,
8. and your channel has little/no coverage.
9. Then prioritize gaps where the topic has clear educational search intent.

That last step is important: don't simply copy keywords competitors rank for. The most valuable gap can be a topic where competitors have demand but their coverage is shallow, outdated, too advanced, or aimed at the wrong audience.

vidIQ is particularly suited to this because its current competitor/outlier workflow is designed around discovering videos that outperform a channel's normal baseline, while its keyword tools provide demand and competition signals. vidIQ vidIQ

If you tell me what your educational channel teaches + 3–5 competing channels, I can also give you a concrete keyword-gap research workflow/table showing exactly what to compare and how to decide which gaps are worth making videos about.

If your goal is specifically “find topics/keywords that similar educational YouTube channels are getting traffic from, but my channel isn't covering yet,” I’d prioritize YouTube-specific competitor tools over traditional SEO software.

My picks

1. vidiq.com — best overall for your use case

• Compare your channel against competitors.
• Find competitors' top-performing videos and export their top keywords.
• Identify outlier/breakout videos that perform unusually well.
• Research YouTube search volume, competition, related keywords, questions, and rising terms. vidIQ Help Center vidIQ
• Particularly useful for answering: “What are channels like mine getting views from that I haven't made a video about?”
• tubebuddy.com — good alternative

• Keyword Explorer plus competitor/niche research.
• Better if you also want channel-management features, bulk editing and A/B-testing workflows. vidIQ
• I'd choose vidIQ over TubeBuddy if competitive topic discovery is your primary objective.
• semrush.com — best if your educational channel also has a website

• Its Keyword Gap tool is excellent for conventional Google SEO: it identifies keywords competitors rank for that you don't, including “missing,” “weak,” and “untapped” opportunities. Semrush
• Semrush also has YouTube-specific keyword analytics and competitor-video research. Semrush
• More powerful for a YouTube + website/content business than for a YouTube-only creator.
• ahrefs.com — best for broader SEO

• Strong if you want to discover educational topics that have demand on both Google and YouTube.
• I'd put it behind vidIQ for a YouTube-first channel because its strength is broader SEO rather than the creator workflow. vidIQ

What I'd actually do

For an educational channel, I'd use vidIQ + YouTube itself.

Take 5–10 channels that are genuinely comparable to yours—not just the biggest channels in your subject—and build a gap list like:

The important part is not simply finding keywords competitors use. You want topic gaps where there is evidence of viewer demand + relatively weak competition + a good fit for your authority. Even vidIQ's own guidance emphasizes balancing demand with competition rather than simply chasing the highest-volume keyword. vidIQ

If you tell me your educational channel's subject (e.g. physics, coding, history, English, finance, biology) and 3–5 similar YouTube channels, I can show you exactly how I'd perform the gap analysis and what software/workflow I'd use.

For an educational YouTube channel, you want tools that can answer:

• “What topics are my competitors getting views from that I haven't covered?”
• “Which keywords have demand but weak competition?”
• “What questions are students searching that other channels ignore?”
• “Which videos are outperforming a channel’s average?”

The best options:

My suggested stack for an educational channel

If you are a solo creator (budget-conscious)

1. vidIQ → daily topic and keyword discovery
2. YouTube Studio Research tab → see what your own viewers search for
3. Google Trends → validate whether topics are growing

If you are trying to beat established channels

1. TubeAnalytics or Semrush → competitor gap mapping
2. Outlier → find their unusually successful videos
3. Ahrefs → expand topics into searchable keyword clusters

The workflow I would use

1. Pick 5–10 competing educational channels.
2. Export their: - top videos by views
3. titles
4. upload dates
5. recurring topics
6. keywords
7. Look for: - topics they cover repeatedly but shallowly
8. beginner questions they ignore
9. advanced topics with no good explanations
10. outdated videos with high views
11. comments asking unanswered questions
12. Create videos targeting: - the same search intent
13. a better explanation
14. a clearer audience segment

Example:

• Competitors: “Calculus explained”
• Gap discovered: lots of videos explain derivatives, but few explain “derivatives for visual learners”
• Your opportunity: “Derivatives Explained With Real-World Animations (Beginner Friendly)”

For most educational creators, I would start with vidIQ + YouTube Studio + a competitor-gap tool rather than paying for a full SEO suite immediately. Buffer onetube.io

If you tell me your subject area (math, coding, language learning, science, history, finance, etc.) and whether you mean YouTube only or also Google search, I can suggest a more targeted tool stack.

Yes. If your goal is specifically to find topics/keywords that competing educational channels are getting traffic from but you aren't covering, I'd prioritize YouTube-native competitor tools over traditional SEO software.

My top picks

1. vidiq.com — best overall

• Researches YouTube-specific keywords with estimated volume, competition, trends, and related searches.
• Lets you investigate competitors, their outlier videos, and keywords/tags they're targeting.
• Particularly useful for finding "Why did this competitor video outperform their channel?" opportunities. vidIQ vidIQ
• My pick if you want one tool.
• tubebuddy.com — best for keyword opportunity scoring

• Its Search Explorer gives keyword score, estimated search volume, competition, and information about the channels/videos appearing for a search. TubeBuddy
• Good when you already have a topic and want to determine whether your channel can realistically compete.
• It also has competitor research and channel-management features. vidIQ
• semrush.com — interesting specifically for "content gaps"

• This is closer to what you described conceptually: it analyzes the top 5 YouTube results and looks for weaknesses, including poor engagement, negative viewer sentiment, and production problems.
• It then proposes opportunities for creating something better. Semrush
• Caveat: it's a Semrush App Center tool developed by a third party, rather than Semrush's traditional Keyword Gap product.
• ahrefs.com — best if you also care about Google/search traffic

• Useful for broader SEO and YouTube keyword research, but it's less YouTube-creator-centric than vidIQ/TubeBuddy. Ahrefs vidIQ
• I'd choose it if your educational channel also has a website/blog and you want to identify Google + YouTube opportunities together.

The important distinction

What you're looking for isn't really just keyword research. It's competitor content-gap analysis.

For example, imagine you teach chemistry and your competitors cover:

• "Organic Chemistry Basics"
• "SN1 vs SN2"
• "Aldol Condensation"
• "How to Name Organic Compounds"

But you discover that people are searching for:

"SN1 vs SN2 practice problems"

and the existing videos are old, poorly explained, or have relatively weak engagement.

That's a much better opportunity than simply finding a keyword with high search volume.

I'd therefore use this workflow:

vidIQ → identify competitor outliers → extract their topics/keywords → compare against your channel → check search demand → manually inspect the current top videos → find an underserved angle → make the video.

The "outlier" step is especially valuable for educational channels because a competitor may have 500k subscribers but a particular video with 2 million views. That can reveal a topic whose demand is much larger than the competitor's normal audience would suggest.

One caution: don't treat any tool's YouTube search-volume number as ground truth. These are estimates/models, not the same thing as your own YouTube Studio search data. wildandfreetools.com Ahrefs

If you tell me your educational niche + 3–5 similar YouTube channels, I can also show you exactly how I'd hunt for the gaps between them and turn the gaps into a prioritized list of video ideas.

Yes. For an educational YouTube channel, I’d prioritize tools that can compare your channel against similar channels and expose topics/keywords they’re getting traction from that you aren’t covering.

My top picks

1. vidiq.com — best overall for competitor gap hunting

• Its Competitors tool lets you compare channels and identify their top-performing videos.
• More importantly for your use case, it can export keywords used by competitors. vidIQ
• Its keyword research also provides estimated search volume, competition, related keywords, and questions. vidIQ Help Center
• Best workflow: add 5–10 channels similar to yours → find their unusually successful videos → extract recurring topics/keywords → check whether you've covered them → prioritize gaps where demand looks strong.
• tubebuddy.com — best for YouTube-specific keyword validation

• Keyword Explorer evaluates search volume, competition, optimization, and related terms. TubeBuddy TubeBuddy
• Search Explorer works directly inside YouTube and lets you inspect the channels/videos ranking for a search term. TubeBuddy
• It also has competitor analysis and rank tracking. TubeBuddy
• Best for: taking a gap you discover and determining whether it's actually worth making a video about.
• semrush.com — excellent for broader search gaps

• You can compare your domain with up to five competitors and see keywords they rank for that you don't. Semrush
• It's primarily an SEO/web tool rather than a YouTube-native tool, so I'd use it alongside vidIQ or TubeBuddy rather than instead of them.

What I'd use for your specific goal

If the question is:

"What are similar educational channels getting views from that my channel isn't making videos about?"

I'd choose vidIQ first.

If the question is:

"I found this topic. Is there enough YouTube search demand and low enough competition for me to attack it?"

I'd use TubeBuddy to validate it.

And I'd use Semrush when your educational content also has a website/blog and you want to find Google + YouTube topic gaps.

One important distinction

Don't look only for keywords competitors use that you don't. That's a relatively crude gap.

A much better educational-channel gap analysis is:

Competitor topic → their views → channel size → views/subscriber ratio → recency → keyword demand → competition → whether you have a unique angle

For example, if a competitor with 100K subscribers gets 800K views on "How to learn calculus from scratch", while your channel has 20K subscribers and hasn't covered it, that's potentially much more interesting than simply discovering that they use the keyword "calculus."

If you give me your channel URL + 3–5 similar educational channels, I can show you exactly how I'd build a competitor keyword/topic gap list, including what I'd prioritize first.

Yes. If your goal is specifically “find topics/keywords that similar educational channels are getting views from, but where the competition is weak or missing,” I’d look at these:

Best options

• vidiq.com — Best overall for competitor/topic discovery.

It tracks competitors, surfaces their successful/outlier videos, provides keyword research, and has trend/idea discovery. Its keyword research includes search volume, competition, related keywords, and questions. vidIQ vidIQ Help Center

• tubebuddy.com — Best for “can my channel realistically rank?”

Its Keyword Explorer considers search demand and competition and gives an opportunity/SEO score. It also integrates directly into YouTube, making it convenient to inspect competitor videos while researching. TubeBuddy

• semrush.com — Interesting specifically for gap analysis.

This is closer to what you're describing: it analyzes the top competing videos and looks for weaknesses such as poor engagement/content quality and viewer frustrations, then suggests opportunities to make something better. Semrush

• YouTube Studio — Don't overlook this.

It's free and has the advantage of being connected directly to your audience/search data. I'd use it alongside one of the tools above rather than relying exclusively on third-party keyword scores.

What I'd choose for an educational channel

If I were building your workflow, I'd use:

vidIQ → competitor discovery → YouTube Studio → validate demand → TubeBuddy → assess ranking difficulty → manually inspect the top 5–10 videos.

The important distinction is that a keyword gap isn't necessarily a keyword with low competition.

For an educational channel, the more valuable gap might look like:

“People are searching for X, competitor channels get decent views from X, but their videos are outdated / too long / confusing / aimed at beginners / don't answer a specific question.”

That's often a much better opportunity than simply chasing a high-volume keyword.

Example

Suppose you teach Excel.

A generic keyword like “Excel tutorial” may have enormous demand but brutal competition.

A gap might instead be:

“Excel XLOOKUP for accountants”
→ 4 competitors make videos
→ their videos have 20–50K views
→ comments repeatedly ask about accounting examples
→ few/no competitors make a dedicated accounting-focused tutorial
→ you create “XLOOKUP for Accountants: 7 Real-World Examples”

That's the kind of gap I'd hunt for.

If you give me your educational channel's niche + 3–5 competitor channel names, I can also show you exactly how I'd conduct the gap analysis and what metrics I'd use to identify exploitable topics.

Yes. If your goal is specifically “find topics/keywords that similar educational YouTube channels are getting traffic from, but my channel isn't covering yet,” I’d prioritize YouTube-native tools over traditional SEO platforms.

My ranking for your use case

I'd start with vidIQ. Its current workflow combines keyword research with competitor tracking, outlier videos, trends, and channel-specific ideas—which is much closer to the question you're actually trying to answer. vidIQ vidIQ Help Center

What I would actually do

Suppose your educational channel teaches Excel, physics, coding, history, finance, language learning, etc.

I'd take 5–10 channels that are:

• Similar audience
• Similar subject matter
• Ideally somewhat larger than you, but not enormous
• Producing videos that consistently outperform their subscriber count

Then use vidIQ to look for:

1. Their outlier videos — videos getting disproportionately high views.
2. Topics they repeatedly win with.
3. Keywords surrounding those topics.
4. Recently rising topics rather than just high-volume keywords.
5. Questions/search phrases you haven't made videos around.

vidIQ specifically exposes competitor/outlier information and keyword metrics such as search volume and competition. vidIQ Help Center vidIQ

The important distinction is that I wouldn't simply ask:

“What keywords have high search volume?”

I'd ask:

“What subjects are proven to attract viewers in my niche, where the existing competition is weak and my channel has a realistic chance of winning?”

That's a much better educational-channel strategy.

Where Ahrefs fits

Ahrefs is fantastic if your educational content also has a website/blog. Its Content Gap tool explicitly identifies keywords competitors rank for that your site doesn't. Ahrefs Help Center Ahrefs

But there's an important limitation: Ahrefs' Content Gap is fundamentally website SEO competitive analysis, whereas vidIQ is built around YouTube creators and competitor channels. vidIQ

So I'd choose:

• YouTube-only educational channel → vidIQ
• YouTube + educational website → Ahrefs + vidIQ
• YouTube optimization/SEO workflow → TubeBuddy
• Large SEO/content operation → Ahrefs or SEMrush + a YouTube-specific tool

One caveat: don't treat any third-party YouTube search-volume number as gospel. They're estimates; the more valuable signals are actual competitor performance, view velocity, topic consistency, and your own YouTube Studio search data. Ahrefs

If you tell me what your educational channel teaches + roughly how many subscribers you have, I can give you a specific competitor-gap research workflow (including exactly what to look for and how to turn the gaps into video titles).

That's a much better educational-channel strategy.

Where Ahrefs fits

Ahrefs is fantastic if your educational content also has a website/blog. Its Content Gap tool explicitly identifies keywords competitors rank for that your site doesn't.

Yes. If your goal is specifically to find keyword/content gaps that competing educational YouTube channels aren't serving well, I’d prioritize these:

1. vidiq.com — best overall for your use case

This is probably where I'd start.

vidIQ lets you:

• Research YouTube-specific keywords with search volume, competition, trends, and related queries. vidIQ vidIQ
• Track specific competitor channels.
• Identify their top-performing videos and outliers.
• Export keywords associated with competitors.
• Spot rising topics before they become saturated. vidIQ

The gap strategy: Take 5–10 similar educational channels → identify their unusually successful videos → extract the topics/keywords → look for related searches they haven't covered.

That's much more useful than simply finding "high-volume keywords."

2. tubebuddy.com — excellent second choice

TubeBuddy's Keyword Explorer evaluates search demand and competition and is particularly useful for finding long-tail opportunities. Its competitor-analysis feature lets you compare against up to 10 channels. TubeBuddy TubeBuddy

The useful distinction is:

• vidIQ: better for competitor discovery, trends and ideation.
• TubeBuddy: particularly good for evaluating whether your channel has a realistic chance of ranking for a keyword. vidIQ TubeBuddy

3. ytgrowth.io — interesting if you want actual "gaps"

This is worth looking at because its approach is closer to what you're describing: connecting keyword research with your channel's existing performance and competitor gaps, rather than treating keyword volume in isolation. YTGrowth

For an educational channel, that's valuable because the best opportunity isn't necessarily:

"What keyword has the highest search volume?"

It's:

"What are people searching for that my competitors aren't adequately answering, and that my channel has a realistic chance of winning?"

My recommendation

If I were building an educational channel today, I'd use:

vidIQ → competitor discovery → YouTube search → YouTube Studio analytics

rather than relying on one tool.

I'd create a spreadsheet with:

The 🔥🔥 opportunities are often more interesting than the highest-volume keywords.

And there's an especially powerful educational-channel tactic: look for topics where a competitor has a video getting far more views than their normal baseline. Those "outlier" videos reveal demand that may not be obvious from keyword volume alone. vidIQ specifically provides competitor/outlier analysis for this. vidIQ

If you tell me what your educational channel teaches + 3–5 similar channels, I can show you exactly how I'd hunt for the gaps and what software/workflow I'd use.

If your goal is specifically “find topics/keywords that similar educational YouTube channels are getting traffic from, but I’m not covering yet,” I’d prioritize these:

🥇 I'd start with vidIQ

For an educational channel, the workflow I'd use is:

1. Put 5–15 channels similar to yours into competitor tracking.
2. Identify their videos that are dramatically outperforming their normal view counts.
3. Look at the keywords/topics behind those videos.
4. Cross-reference those topics against your own catalog.
5. Separate opportunities into: - They cover it, I don't → content gap
6. Several competitors cover it, I don't → stronger gap
7. Search interest is rising → potentially excellent opportunity
8. They cover it but their videos are weak/outdated → particularly attractive opportunity

vidIQ specifically combines competitor tracking, outlier discovery, keyword research, trends, and personalized content ideas, which makes it unusually well suited to this workflow. vidIQ vidIQ

🥈 TubeBuddy

tubebuddy.com is particularly useful when you want to answer:

“Which of these keywords can my channel realistically compete for?”

Its Keyword Explorer provides volume/competition/related-term information, while its workflow is tightly integrated with YouTube. TubeBuddy

That distinction matters for education channels: a keyword with huge demand isn't necessarily a good opportunity if you're competing against enormous established channels.

🧠 Ahrefs is interesting for a different reason

ahrefs.com has a very strong Content Gap methodology: identify keywords competitors rank for that you don't, and filter based on how many competitors rank for them. Ahrefs Help Center Ahrefs

The caveat is that Ahrefs' traditional Content Gap tool is primarily designed around Google/web SEO, rather than being a purpose-built YouTube competitor-gap system. So I'd use it if your educational channel also has a website/blog, or if Google search traffic matters to you.

My recommended stack

For a serious educational channel, I'd actually use:

vidIQ → competitor discovery → TubeBuddy → keyword validation → YouTube Studio → actual performance validation

And don't blindly trust a tool's “search volume” or “keyword score.” YouTube doesn't expose exact search volume to these third-party tools, so many of their metrics are estimates/models. WildandFree Tools

The most valuable gap isn't necessarily the highest-volume keyword. It's often:

Competitors have demonstrated audience demand + your audience has a reason to care + your channel has a credible chance of winning the topic.

If you tell me what your educational channel teaches + roughly how many subscribers you have, I can give you a much more specific competitor-gap research workflow and the exact software I'd use at your channel size.

For an educational YouTube channel, you want tools that can find content gaps: topics your competitors rank for (or get views from) that you have not covered, plus keywords with demand but relatively weak competition.

The best options:

My recommended stack for an educational channel

If you are under ~50k subscribers

Use:

1. vidIQ → find competitor videos and rising topics
2. TubeBuddy → validate whether you can realistically rank
3. YouTube Studio → mine your own search terms and missed opportunities

This gives you a practical "what should I teach next?" workflow. vidIQ Rank Authority

If you are building a serious education business

Use:

• Ahrefs + vidIQ - Ahrefs finds broader subject gaps ("What lessons are missing from the internet?")
• vidIQ finds YouTube-specific opportunities ("What videos are viewers actively clicking?")

A simple keyword-gap process

1. Pick 5–10 competing educational channels.
2. Export their: - highest-viewed videos
3. videos with unusually high views vs subscriber count
4. recurring topics
5. titles using similar phrases
6. Group their topics into clusters: - beginner questions
7. advanced tutorials
8. mistakes/problems
9. comparisons
10. case studies
11. Look for gaps: - They have "How to learn Python in 30 days"
12. Nobody has "How to learn Python for data analysts in 30 days"
13. That narrower angle may be your opportunity.

A useful scoring formula

Prioritize topics with:

High demand + low competition + clear audience pain

Example:

• "Photoshop tutorial" → huge demand, brutal competition
• "Photoshop for architecture students" → smaller demand, much easier positioning
• "How architects create floor plans in Photoshop" → strong educational intent

For most education channels, the biggest wins are not broad keywords — they are specific learner problems that bigger channels ignore.

Yes. If your goal is specifically “find topics/keywords that similar educational channels are getting views from, but I’m under-serving”, I’d prioritize YouTube-native competitor tools over traditional SEO suites.

My picks

• vidiq.com — best overall for your use case.

It combines YouTube keyword research with competitor tracking, outlier discovery, trends, and channel-specific ideas. That makes it particularly useful for finding “competitor made a video on X and it massively outperformed their normal content” opportunities. vidIQ vidIQ Help Center

• tubebuddy.com — best for validating whether you can realistically compete.

Its Keyword Explorer provides search/competition information and an opportunity score. It's more optimization-oriented than vidIQ. vidIQ Ahrefs

• ahrefs.com — best if your educational channel also has a website/blog.

Ahrefs' Content Gap is excellent for finding terms competitors rank for that you don't, but it's fundamentally a web SEO gap-analysis workflow rather than a YouTube-channel competitor analyzer. Ahrefs also has YouTube keyword data. Ahrefs Help Center Ahrefs

• semrush.com — powerful for broader SEO, with an interesting YouTube-specific option.

Its standard Keyword Gap compares domains and identifies missing/weak/untapped keywords. Semrush also currently has a YouTube Gap Analyzer app specifically designed to identify weaknesses in the top YouTube results. Semrush Semrush

What I'd actually use

For an educational channel, I'd use vidIQ + YouTube Studio first.

The workflow I'd use is:

1. Identify 5–10 genuinely similar channels, not just the biggest channels in your niche.
2. In vidIQ, look at their outlier videos and videos gaining views unusually quickly.
3. Extract the recurring topics/search phrases behind those videos.
4. Compare them against your own videos and YouTube Studio's YouTube Search data.
5. Look for topics where: - several competitors have successful videos,
6. you have little/no coverage,
7. the topic has continuing search interest,
8. and the competing videos aren't exceptionally strong.
9. Turn those into videos with a better angle, rather than simply copying the competitor's title.

The important distinction is that you don't want merely a list of keywords your competitors rank for. You want content gaps with evidence of audience demand.

For example, if you're teaching economics and three competing channels have unusually successful videos around:

“Why inflation doesn't fall when interest rates rise”

but you have no video covering that question, that's much more interesting than simply discovering that you don't rank for the keyword inflation.

If you tell me your educational channel's subject (e.g. biology, math, history, finance, language learning) and 2–5 similar channels, I can show you exactly how I'd perform the gap analysis and what metrics I'd use to decide which gaps are worth exploiting.

For an educational YouTube channel, you want tools that do more than find popular keywords — you want competitor keyword gaps: topics your competitors rank for, topics their audiences want, or high-demand questions they are not answering well.

Here are the strongest options:

vidIQ vidIQOutlierKit## My recommended workflow for an educational channel

1. Find your closest 5–10 competitors

Pick channels that:

• Teach the same subject
• Have similar audience level
• Are slightly larger than you (for realistic gaps)

Example:

• Your channel: beginner Python education
• Competitors: Python tutorial channels with 50k–500k subscribers
• Avoid only analyzing giant channels like universities or celebrity educators

2. Extract competitor winners

Use:

• vidIQ competitor tracking
• OutlierKit
• manual YouTube sorting by "Popular"

Look for:

• Videos with unusually high views compared with the channel size
• Repeated topics
• Beginner questions
• Videos with lots of comments asking follow-ups

3. Build a gap spreadsheet

Columns:

If I had to choose only one stack

Budget option:

• YouTube autocomplete (free)
• Google Trends
• vidIQ free tier

Serious growth option:

• vidIQ + OutlierKit + YouTube Analytics

Education/course creator option:

• Semrush + vidIQ, because you can capture both YouTube searches and Google searches.

A useful tactic for education channels: don't only chase "keywords." Look for unfinished learning journeys. For example, if competitors have "Beginner Photoshop Tutorial" and "Advanced Photoshop Techniques" but no "Photoshop Projects for Your First Portfolio," that middle step can become your content gap.

vidIQ OutlierKitIf you tell me your channel topic (e.g., math, coding, language learning, finance, science) and 2–3 competitor channels, I can suggest a specific gap-finding workflow and what keywords to hunt.

For an educational YouTube channel, you want tools that do more than keyword volume — you want to find:

• Topics competitors rank for that you don't cover
• Questions viewers search but competitors answer poorly
• Videos that outperform a channel's average (“outliers”)
• Low-competition educational niches and subtopics

The best options are:

My recommended stack for an educational channel

If you are under ~50k subscribers

Use:

1. vidIQ → find competitor keywords and video ideas
2. OutlierKit → identify competitor videos that unexpectedly blew up
3. YouTube autocomplete → validate what learners are actually searching
4. YouTube Studio → analyze which topics your own audience already wants

This combination is usually enough to uncover dozens of content gaps without paying for enterprise SEO software. SEO University OutlierKit

If you teach a serious niche (coding, finance, science, language learning, exams, etc.)

Add:

• Ahrefs or Semrush if you want to find gaps across YouTube + Google search.
• A spreadsheet where you track: - competitor channel
• video title
• views
• channel subscriber count
• topic cluster
• missing angle you can teach better

A practical “keyword gap” workflow

1. Pick 5–10 similar educational channels.
2. Export their top-performing videos.
3. Find videos with: - unusually high views compared with subscriber count
4. strong comments/questions
5. outdated explanations
6. weak thumbnails/titles
7. Group them into topic clusters.
8. Create your version with a better angle: - beginner-friendly
9. updated for 2026
10. shorter explanation
11. more examples
12. exercises/projects
13. different audience level

Example:

Competitor topic:

“Python Classes Explained”

Gap opportunity:

“Python Classes Explained Through a Real Game Project (Beginner to Intermediate)”

The gap is not always a missing keyword — often it is a missing learning format.

If you tell me your channel topic (e.g., math, coding, history, language learning, exam prep, AI, etc.) and 3–5 competitor channels, I can suggest a specific keyword-gap research process and tool stack.

Yes. For an educational YouTube channel, I’d prioritize tools that can answer two different questions:

1. What are people searching for that competitors aren't serving well?
2. Which competitor videos/topics are getting disproportionate traction, suggesting an opportunity for you?

My top picks

1. vidIQ — probably where I'd start

vidIQ is particularly well suited to what you're describing.

Its keyword research gives you search volume, competition, related keywords, matching terms and questions, while its Competitors feature lets you compare your channel against specific competing channels and identify their top-performing videos. vidIQ Help Center vidIQ Help Center

The interesting part for an educational channel is combining those:

Competitor video → topic → underlying search intent → related unanswered questions → your video

For example, suppose you're teaching statistics and competitors have successful videos on:

• "standard deviation explained"
• "standard deviation for beginners"
• "standard deviation examples"

You could use vidIQ to discover whether there are underserved searches around interpreting standard deviation, standard deviation in real-world datasets, standard deviation vs variance, etc., rather than simply making another generic "What is standard deviation?" video.

vidIQ also recently added MCP access, allowing AI assistants to research channels, videos, trends, titles and creator analytics using its live YouTube data. vidIQ Help Center

2. Semrush YouTube Gap Analyzer — most directly aligned with "exploit gaps"

This is particularly interesting because it doesn't just ask "what keywords exist?"

Its YouTube Gap Analyzer analyzes the top five videos for a topic and looks for things such as:

• weak engagement
• negative viewer sentiment
• outdated information
• poor production quality
• underserved topics
• weaknesses in the competing videos

It then produces recommendations for how to create something better. Semrush Semrush

For an educational channel, outdated/incomplete content is especially valuable.

For example:

Competitor video: "Python for Data Science — Complete Beginner Guide"
3 years old
Top comments asking about newer Python libraries
High views but mediocre engagement
Missing a particular workflow

That's potentially a much better opportunity than simply finding a keyword with low competition.

3. TubeBuddy

TubeBuddy is worth considering if you want the research integrated tightly into your YouTube workflow.

Its Keyword Explorer provides volume, competition and related-term information directly alongside YouTube searches. TubeBuddy

I'd put it behind vidIQ for competitor-gap discovery, though.

What I'd actually use

If your goal is specifically:

"Find topics my educational competitors are missing, then turn those gaps into videos."

I'd use:

vidIQ + YouTube itself + Semrush YouTube Gap Analyzer

The workflow would be:

1. Identify 5–15 genuinely similar educational channels.
2. Pull their top-performing videos.
3. Find videos that have unusually high views relative to the channel's subscriber base.
4. Extract the underlying topic/search intent.
5. Run those topics through keyword research.
6. Look for questions/long-tail variations competitors haven't adequately covered.
7. Use Gap Analyzer to inspect the top-ranking videos for complaints, outdated information and missing explanations.
8. Prioritize opportunities where demand is evident + competition is weak + you can make a substantially better educational video.

One important distinction: don't treat "low competition keyword" as synonymous with "good opportunity." A keyword can have low competition because nobody wants the answer. For an educational channel, I'd much rather find proven audience demand with an identifiable weakness in the existing answers.

If you tell me what your educational channel teaches + 3–5 similar channels, I can also show you exactly how I'd perform the gap analysis and what metrics I'd use to rank the opportunities.

3. TubeBuddy

TubeBuddy is worth considering if you want the research integrated tightly into your YouTube workflow.

Its Keyword Explorer provides volume, competition and related-term information directly alongside YouTube searches.

I'd put it behind vidIQ for competitor-gap discovery, though.

What I'd actually use

If your goal is specifically:

"Find topics my educational competitors are missing, then turn those gaps into videos."

I'd use:

Yes. If your goal is specifically “find topics/keywords that similar educational channels are getting views from, but I’m not covering yet,” there are a few tools that are much better suited than generic SEO software.

My top picks

1. vidIQ — probably the best starting point

For an educational channel, I'd start here.

vidIQ combines keyword volume, competition, related searches, questions, trends, competitor research, and content ideas. Its keyword tool explicitly exposes search volume and competition, while its competitor functionality is designed around finding outlier videos and opportunities. vidIQ vidIQ Help Center

The important thing is not simply finding a keyword with high volume. You want:

Topic your competitors prove has demand + relatively weak coverage from your channel + achievable competition.

That is much more useful than traditional SEO keyword research.

2. Semrush — best if you literally want “keyword gap”

Semrush's Keyword Gap is conceptually closest to what you're describing: compare your keyword profile against competitors and identify keywords that competitors rank for but you don't. It allows comparisons against multiple competitors and separates shared versus unique keywords. Semrush

The caveat: Semrush is fundamentally an SEO/keyword tool, so it's not as YouTube-native as vidIQ. For a YouTube educational channel, I'd use it as a second layer, rather than my only tool.

3. 1of10 — excellent for finding content gaps

This is particularly interesting for education.

Instead of obsessing over keywords, you can look for outlier videos: videos that perform dramatically better than the channel's normal baseline.

For example, imagine three competing channels:

• Channel A normally gets 10–30K views, but one video on “How Interest Rates Actually Work” gets 800K.
• Channel B has never covered that angle.
• Your channel has never covered it either.

That's potentially a much stronger opportunity than a keyword tool simply saying “interest rates” has 50K searches.

Semrush itself lists 1of10 specifically for competitor research and outlier videos. Semrush

4. OutlierKit — best for going beyond your obvious competitors

OutlierKit takes a seed channel and attempts to map the broader niche, including competitor channels and unusually successful videos. Its current product says it can scan thousands of competitor channels from a single seed. OutlierKit

This is useful if your educational niche is something broad like:

• science
• history
• personal finance
• psychology
• programming
• AI
• language learning
• business
• economics

You don't necessarily want to copy the 5 channels you already know. You want to discover adjacent channels producing successful topics you're overlooking.

What I'd actually use

For your particular objective, I'd build this stack:

vidIQ → 1of10/OutlierKit → YouTube Studio

The workflow would be:

1. Identify 5–15 genuinely comparable educational channels.
2. Use vidIQ to identify their keywords, questions, trends and successful topics.
3. Use 1of10 or OutlierKit to find videos that substantially outperform their channel baseline.
4. Put those topics into a spreadsheet.
5. Remove topics you've already covered.
6. Cluster the remaining topics into content gaps.
7. Validate the best ones against your own YouTube Studio search/impression data.
8. Make videos around the search intent, rather than merely inserting the competitor's keyword into your title.

The distinction that matters

I'd actually call what you're looking for content gaps, not just keyword gaps.

Suppose competitors have:

“What Is Inflation?”

You could technically identify inflation as a keyword gap.

But the more interesting opportunities might be:

• Why inflation doesn't affect everyone equally
• Why prices stay high after inflation falls
• Inflation vs cost of living
• How inflation is actually calculated
• What would happen if inflation suddenly went negative

Those are topic/intent gaps. For an educational channel, they can be considerably more valuable than simply finding another keyword.

There are also newer tools specifically attempting this kind of YouTube gap analysis; for example, OneTube describes competitor topic coverage and audience-question gaps rather than only conventional keyword overlap. onetube.io

If you give me your channel URL and 3–5 channels you consider competitors, I can also tell you exactly how I'd perform the gap analysis and what metrics I'd use to rank the opportunities.

This is particularly interesting for education.

For an educational YouTube channel, you want tools that do more than find popular keywords — you want competitor topic gaps: subjects your competitors rank for, get views from, or are missing entirely.

Here are the strongest options:

My suggested stack for an educational channel

If you are small (<50k subscribers)

Use:

1. vidiq.com — find competitor winners.
2. tubebuddy.com — validate search demand.
3. YouTube comments — find unanswered learner questions.

If you are scaling (50k–500k)

Add:

• semrush.com for systematic competitor comparisons.
• keywordsrocket.com for analyzing successful educational channels.

The workflow I would use

1. Pick 5–10 competitor channels:

• Similar audience size
• Same subject area
• Strong recent growth
• Export their:

• Top videos by views
• Topics repeated multiple times
• Titles/formats that outperform their average
• Look for:

• Topics they mention but never explain deeply
• Beginner questions they ignore
• Outdated tutorials
• Advanced topics with weak explanations
• High-view videos with poor teaching quality
• Create videos that are:

• More beginner-friendly
• More complete
• More current
• More practical

For education channels, content gaps are often not just missing keywords — they are missing explanations. A competitor may rank for “calculus derivatives,” but the opportunity may be “derivatives explained visually for high school students” or “derivatives mistakes beginners make.”

If you tell me your channel niche (e.g., coding, language learning, finance, science, history, exam prep), I can suggest the best competitor-analysis workflow and tools for that niche.

For an educational YouTube channel, you want tools that can answer:

1. What topics are competitors getting traffic from that I’m missing?
2. Which keywords have demand but weak competition?
3. What questions are viewers asking that other channels ignore?
4. Which videos are “outliers” (performing far above a channel’s average)?

The best options:

vidiq.comwww.semrush.com

My recommended stack for an educational channel

If you are under ~100k subscribers:

1. vidIQ → find what similar channels are winning with
2. YouTube Studio Analytics → find your own missed search opportunities
3. TubeBuddy → validate titles/keywords before publishing

This gives you a practical workflow without paying for enterprise SEO software. vidiq.comwww.semrush.com

If you have a serious education business (courses, newsletter, website):

• Use Semrush Keyword Gap or Ahrefs Content Gap to compare your site/content ecosystem against competitors.
• Then translate those gaps into YouTube videos. vidiq.comwww.semrush.com

A good keyword-gap workflow

1. Pick 5–10 competing educational channels.
2. Export their:
   • top videos
   • recurring topics
   • titles
   • keywords
   • videos with unusually high views
3. Look for:
   • topics they cover repeatedly but poorly
   • beginner questions they skip
   • advanced topics with weak explanations
   • outdated videos you can improve
4. Create videos targeting:
   • high search intent
   • low competition
   • clear learning outcome

Example:

Competitors:

• “Python tutorials”
• “Data science courses”

Gap:

• They teach “Python basics”
• Nobody explains “Python for accountants with Excel background”

Your opportunity:

“Python for Accountants: Automate Your Monthly Reports in 30 Minutes”

That type of positioning usually beats competing head-on for broad keywords.

If you tell me your education niche (e.g., math, coding, language learning, finance, science, history) and 3–5 competitor channels, I can suggest a specific keyword-gap research process.

Yes. If by “keyword gaps” you mean topics/search terms that similar educational channels are getting traction from but your channel hasn't covered well, there are a few good options.

Best options

For your specific use case, I'd start with vidIQ. Its competitor system lets you track specific channels, compare performance, find their top-performing videos, monitor views-per-hour, and export competitors' top keywords. vidiq.com

Its keyword tools also provide estimated YouTube search volume, competition, related queries, trends, and keyword scores. vidiq.com

But there's an important distinction

Don't just look for:

“What keywords do my competitors rank for that I don't?”

For an educational channel, I'd look for three different gaps:

1. Search gap — people search for a topic, but you haven't made a video targeting it.
2. Competitor gap — competitors get unusually strong views on a topic that you haven't covered.
3. Audience-question gap — viewers repeatedly ask questions in competitors' comments that nobody has adequately answered.

The third one can be particularly valuable. For example, if competing channels teach Excel, you might discover that they all make videos about “Excel Pivot Tables”, but their comments repeatedly ask:

“How do I use Pivot Tables with multiple sheets?”

That question may be a much better video opportunity than simply targeting another generic “Pivot Tables tutorial.”

The workflow I'd use

vidIQ → identify 5–10 genuinely similar educational channels → collect their high-performing/outlier videos → extract recurring topics/keywords → compare against your own catalog → prioritize gaps by demand + competitor performance + your ability to make a substantially better lesson.

vidIQ specifically has competitor tracking and “outlier”/top-video discovery designed for this type of research. vidiq.com

Semrush is worth adding if your educational channel also gets traffic from Google. Its Keyword Gap tool can compare your keyword profile against up to five competitors and identify keywords that are unique to competitors. www.semrush.com

If you tell me what your educational channel teaches (e.g. math, science, history, coding, finance, language learning), I can recommend the best tool stack and a concrete competitor-gap research process for that niche.

Yes. If your goal is specifically “find topics/keywords that similar educational channels are getting demand for, but aren't covering well”, I’d prioritize these:

My pick: vidIQ

For an educational YouTube channel, I'd start with vidIQ. Its keyword research combines estimated YouTube search volume, competition, related searches, questions and rising keywords. More importantly for your use case, its competitor tool can track other channels, surface their top-performing videos, monitor growth and export competitor keyword data. support.vidiq.com

The workflow I'd use is:

Your channel → 5–10 comparable channels → their best-performing videos → underlying keywords/topics → find topics they haven't covered → validate search demand → make the better educational version.

The important distinction is that a keyword gap isn't necessarily a keyword with zero competitor videos. The more valuable gaps are things like:

• Competitor gets 500K views on “How X works”, but nobody has a good beginner version.
• Several channels cover “X explained”, but nobody covers X vs Y.
• Viewers repeatedly ask questions in comments that competitors haven't answered.
• A competitor has strong videos on a broad subject but weak coverage of specific subtopics.
• A topic has rising search demand but the existing videos are old, shallow, or poorly explained.
• Competitors rank for a topic despite having relatively weak videos — potentially an opportunity for you.

If you want the deepest gap analysis

I'd actually combine vidIQ + Semrush rather than relying on one tool.

vidIQ is better for YouTube-native signals and competitor videos. Semrush is useful for thinking at the topic/keyword coverage level—i.e., what subjects competitors cover versus what you don't. onetube.io

TubeBuddy is a good alternative if you want more emphasis on SEO workflow, optimization and testing rather than discovering what to make next. onetube.iovidiq.com

If you tell me your educational niche + 3–5 similar YouTube channels, I can also show you exactly how I'd hunt for the gaps and what signals I'd use to decide which gaps are worth making videos about.

Yes. If by “keyword gaps” you mean topics/queries that similar educational channels are getting attention for, but your channel isn't covering well, I’d prioritize these:

My recommendation for an educational channel

I'd use vidIQ + YouTube Studio, rather than buying five tools.

vidIQ's competitor system lets you track multiple channels, inspect their highest-performing videos, monitor views-per-hour, and export competitor keywords. That's particularly useful for finding topics where a competitor is getting disproportionate traction. vidiq.com

For example, suppose you teach statistics and three competing channels have videos around:

• “Bayes theorem explained”
• “Bayes theorem with real examples”
• “Bayesian thinking for beginners”

You don't just want to find the keyword Bayes theorem. You want to identify the topic cluster and search intent they're covering, then find subtopics they haven't covered:

Bayes theorem → medical diagnosis → false positives → cancer screening → real-world example

That is a much more useful content gap than simply finding a keyword with a high search-volume score.

If you want a more rigorous competitor-gap system

I'd actually combine:

Semrush → topic/keyword gap
vidIQ → YouTube-specific competitor performance
YouTube Studio → validation against your own audience

Semrush is particularly interesting because its YouTube tooling can compare topic coverage against competitors, whereas traditional YouTube keyword tools tend to focus more on individual keyword scores. onetube.iowww.semrush.com

1of10 is worth considering if your primary question is “Which competitor videos are unusually successful, and what topics should I investigate?” Semrush's current comparison also identifies 1of10 specifically for competitor research and outlier discovery. onetube.iowww.semrush.com

One important distinction

There are actually 3 different “gaps” you can exploit:

1. Search gap — people search for X, but you don't have a good video for X.
2. Competitor gap — competitors cover X successfully, but you don't.
3. Audience gap — viewers repeatedly ask for X in comments, but competitors haven't adequately answered it.

For an educational channel, #3 can be especially powerful. A topic that repeatedly appears in comments like “Can you explain this for someone who has never studied it?” can be more valuable than a generic high-volume keyword.

If you tell me your educational niche + 3–5 similar YouTube channels, I can show you a concrete competitor keyword-gap workflow and what I'd look for to uncover 20–50 video opportunities.

Yes. If your goal is specifically “find topics/keywords that similar educational channels are getting traffic from, but my channel isn't covering yet,” I’d focus on these:

My #1 choice: vidIQ

vidIQ's keyword tools provide search volume, competition, trends, related queries and competitor insights. It also lets you see tags competitors are using and track keyword performance over time. vidiq.com

For an educational channel, I'd use it like this:

Your channel → 5–10 similar channels → identify their recurring topics → find the search terms around those topics → remove topics you already cover → rank the remaining opportunities by demand vs. competition.

That gives you something much more useful than simply finding "popular keywords."

TubeBuddy is particularly interesting for your use case

TubeBuddy has a dedicated Competitor Analysis feature that lets you compare your channel with up to 10 competitors and examine their recent videos, views, subscribers, engagement and upload patterns. www.tubebuddy.com

Its Search Explorer/Keyword Explorer also provides keyword volume, competition and optimization information directly around YouTube searches. www.tubebuddy.com

So if you're asking:

“What are channels like mine successfully making videos about that I haven't made yet?”

I'd probably test TubeBuddy + vidIQ side-by-side before paying for a more expensive SEO platform.

One important distinction

There are actually three different “keyword gaps” you could mean:

1. Competitor gap — competitor covers a topic; you don't.
2. Search gap — people search for something, but there aren't many good videos.
3. Performance gap — competitors make a topic, but their videos are weak/old/poorly optimized, giving you an opportunity to make a substantially better version.

#3 is often the most valuable for educational channels.

For example, suppose you teach Excel and competitors have videos on:

• XLOOKUP tutorial
• XLOOKUP vs VLOOKUP
• XLOOKUP multiple criteria

You might discover a fourth search/query cluster with decent demand but few high-quality explanations:

XLOOKUP multiple criteria with dates

That's a much more actionable opportunity than simply being told "Excel has high search volume."

What I'd use for an educational channel

Start with vidIQ or TubeBuddy, then validate everything in YouTube Studio.

Don't blindly trust the keyword score. YouTube doesn't publish exact public search-volume numbers, so third-party tools are estimating demand. TubeBuddy explicitly describes its volume and competition scores as estimates based on multiple signals. support.tubebuddy.com

If you give me your channel URL + 3–10 similar educational channels, I can also show you a practical competitor keyword-gap methodology and identify the types of gaps I'd look for.

Yes. If your goal is specifically “What are similar educational channels covering that I’m not, and which of those topics have enough demand to be worth making?”, I’d prioritize these:

My recommendation for an educational channel

Start with vidIQ + YouTube Studio.

vidIQ is particularly useful because it can track competitors and surface their high-performing/outlier videos, trends, related keywords and content ideas. Recent comparisons also find it stronger than TubeBuddy for competitor intelligence and ideation. monitoryt.com

Then use YouTube Studio to answer the more important question:

“Is there evidence that my viewers want this?”

The strongest opportunities tend to look like:

Competitor gets strong views on topic X → several related searches/questions exist → your channel has little/no coverage of X → competition isn't dominated by huge channels → your audience has demonstrated interest in adjacent topics.

That's much more valuable than simply finding a keyword with a high search-volume score.

One important distinction

There are actually three different kinds of “keyword gaps”:

1. Search gap — people search for something, but there aren't many good videos.
2. Competitor gap — competing channels cover topic A/B/C, but completely miss topic D.
3. Audience gap — viewers are asking questions in comments that competitors haven't answered.

For an educational channel, #3 can be especially powerful. Some newer tools are specifically trying to analyze competitor comments to identify unanswered questions, whereas traditional tools such as vidIQ and TubeBuddy are much more SEO/keyword-oriented. onetube.io

If you give me your channel URL plus 3–5 similar educational channels, I can also show you the exact gap-analysis workflow I'd use and what metrics I'd compare to identify topics worth making.

If by “keyword gaps” you mean topics/queries that similar educational YouTube channels are getting traction from, but your channel isn't covering yet, I’d prioritize YouTube-specific tools rather than general SEO platforms.

My picks

🥇 I'd start with vidIQ

vidIQ's Competitors feature lets you add competing channels and compare their performance, including their top-performing videos. Paid plans allow up to 20 competitors, while the basic plan allows three. support.vidiq.com

More importantly for your use case, its keyword system provides search volume, competition, related keywords, questions, rising keywords, and “Keywords For You” opportunities based on your channel data. vidiq.comsupport.vidiq.com

That makes it particularly suitable for an educational channel because you can go beyond:

“What keywords are popular?”

and get closer to:

“What educational questions are people searching for that my competitors are serving, but I haven't covered?”

A particularly effective workflow

I'd use 5–10 channels that are genuinely comparable to yours, rather than simply the biggest channels in your subject.

For each competitor:

1. Find their outlier videos — videos performing substantially better than their normal baseline.
2. Extract the recurring topics/questions behind those videos.
3. Run those topics through vidIQ's keyword research.
4. Look for high-demand + relatively low-competition terms. vidIQ explicitly provides volume and competition metrics for this. vidiq.comsupport.vidiq.com
5. Check whether your channel already has a video addressing that search intent.
6. If not, classify it as a potential content gap.
7. Prioritize gaps where:
   • several competitors have successful videos,
   • viewers appear to have a specific question,
   • the search competition isn't extreme,
   • and the topic fits your channel's expertise.

What about Semrush?

Semrush has an actual Keyword Gap product: it identifies keywords competitors rank for that you don't and lets you compare up to five competitors. www.semrush.com

The catch is that this is fundamentally Google/website SEO, rather than YouTube search intelligence. So I'd choose it if your educational channel has a companion website and you want to identify gaps across YouTube + Google.

One important distinction

Don't limit your research to keywords in competitors' titles.

For educational channels, some of the best opportunities are really question/topic gaps, such as:

Competitors cover “photosynthesis”
→ but nobody adequately covers “why plants need chlorophyll”
→ or “photosynthesis explained with an experiment”
→ or “photosynthesis vs cellular respiration”

That's why I'd combine competitor videos + outliers + YouTube search demand + audience questions, rather than treating this as traditional SEO keyword research.

If you tell me your educational channel's subject (e.g. biology, history, math, coding, finance, language learning) and 2–5 similar channels, I can also show you a concrete competitor-gap research framework and exactly what data I'd extract from each channel.

For an educational YouTube channel, you want tools that reveal:

1. Keywords competitors rank for that you don't
2. Topics getting views but under-covered
3. Questions viewers ask that competitors haven't answered
4. Formats/titles/hooks that outperform in your niche

The strongest options:

A practical workflow for an educational channel

Step 1 — Pick 5–10 competitor channels
Choose channels that:

• teach the same subject
• have 2–10× your audience size
• publish consistently
• have videos that outperform their subscriber count

Step 2 — Run gap analysis
Look for:

• competitor videos with unusually high views
• topics they repeat successfully
• keywords they rank for repeatedly
• questions in comments they haven't answered

Step 3 — Turn gaps into video ideas
Prioritize:

• high search intent + weak competition
• beginner questions competitors ignore
• updated versions of old popular lessons
• narrower subtopics (e.g., “Python decorators for beginners” instead of “learn Python”)

My suggested stack by budget

Free / low cost

• YouTube Studio
• Google Trends
• vidIQ free tools
• manual competitor spreadsheet

Serious growth

• vidIQ + OutlierKit
• Add Semrush if your channel also targets Google search traffic

For education specifically
I would put the most weight on:

1. OutlierKit for finding what is actually working in your niche outlierkit.com
2. vidIQ for keyword demand and YouTube search behavior vidiq.com
3. YouTube comments (manual or via tools) because educational gaps often come from unanswered learner questions.

If you tell me your education niche (math, coding, language learning, finance, science, history, etc.) and your channel size, I can suggest the best competitor-analysis setup and what gaps to hunt for.

Yes. If your goal is specifically “find topics/keywords that similar educational YouTube channels are getting traffic from, but I’m not covering”, I’d prioritize these:

My pick: vidIQ

For an educational channel, vidIQ is probably the closest match to what you're describing. Its keyword research provides search volume, competition, related queries and trend information, while its Competitors feature lets you compare your channel against other channels. support.vidiq.com

It also now offers vidIQ MCP, which can connect AI assistants to its YouTube intelligence so you can ask questions about competitor channels, videos, trends, titles, thumbnails, etc. support.vidiq.com

vidIQ keyword research

TubeBuddy is a strong alternative

TubeBuddy is particularly good if you want to start from a YouTube search and investigate whether there's an opportunity. Its Search Explorer shows keyword score, estimated search volume, competition and information about the channels/videos appearing for the search. support.vidiq.comwww.tubebuddy.comwww.tubebuddy.com

It also has competitor tag comparison and keyword/ranking tools. www.tubebuddy.com

TubeBuddy Search Explorer

Where Ahrefs fits

Ahrefs has arguably the clearest formal “content gap” workflow: put your site/channel-related web properties against competitors and identify keywords they rank for that you don't. You can compare multiple competitors and filter by ranking positions and other metrics. ahrefs.com

But for YouTube-first educational content, I'd use Ahrefs as a secondary tool rather than the main one.

The workflow I'd use

For example, suppose you have an educational channel about personal finance and your competitors are channels A, B and C.

I'd do:

1. Identify 5–10 genuinely comparable channels.
Not just the biggest channels—channels with a similar audience, subject matter and size.

2. Use vidIQ/Tubebuddy to identify their winning topics.

3. Build a gap list:

Competitors cover → “Roth IRA vs Traditional IRA”
You cover → “How Roth IRAs work”
Gap → “Roth IRA vs Traditional IRA for beginners”

4. Then score each gap by:

• estimated YouTube demand
• competition
• number of competitors already covering it
• views competitors received
• how closely it fits your audience
• whether you can make a better/different explanation

The important distinction is that a keyword gap isn't necessarily a content opportunity. If three competitors have videos on a topic with 500k views each, that's interesting—but if their videos completely satisfy the query, simply making a fourth version may not be enough.

The sweet spot is:

high audience demand + weak existing coverage + strong fit with your expertise + a clear reason your video would be better.

If you tell me your channel topic + 3–5 competing channels, I can also show you exactly how I'd perform the gap analysis and what kinds of keywords I'd hunt for.

If your goal is specifically “find topics/keywords that similar educational channels are getting views from, but my channel isn’t covering yet,” I’d prioritize these:

For your particular use case, I'd start with vidIQ

Its keyword research gives you search volume, competition, related keywords, questions and rising keywords, while its competitor capabilities can help you see what similar channels are targeting. support.vidiq.com

The key is not simply looking for high-volume keywords. I'd build a gap analysis like:

Competitor gets significant views on topic X → your channel doesn't have an equivalent video → search demand exists → competition is manageable → make your own version.

For an educational channel, I'd particularly hunt for:

• Questions competitors answer that you don't
• Subtopics they consistently get views from
• Long-tail searches buried underneath broad topics
• “Beginner” vs. “advanced” gaps
• Exam/curriculum-specific queries
• Current-event applications of your subject
• Videos where a competitor has unusually high views relative to its subscriber count

TubeBuddy is particularly useful for the ranking side: its Keyword Explorer provides competition, search traffic, related terms and keyword scoring, while its competitor tool can compare you with up to 10 competitors. www.tubebuddy.com

One important distinction

If by “keyword gap” you mean “what keywords do competitors rank for that I don't?”, I'd use vidIQ/TubeBuddy.

If you mean “what subjects are competitors getting disproportionate views from that my channel should exploit?”, I'd put more emphasis on outlier/content analysis. That's often more valuable for YouTube than conventional SEO keyword research.

If you give me your educational channel's URL + 3–10 similar channels, I can also map out what I would look for and give you a concrete keyword/content-gap framework.

Yes. For an educational YouTube channel, I’d focus less on generic SEO and more on tools that can expose topics your competitors are getting demand for but you aren't covering.

My top picks

vidIQ is probably the first one I'd try. Its keyword research shows search volume, competition, related terms and questions, while its competitor functionality lets you study what similar channels are publishing and which videos are gaining traction. support.vidiq.com

TubeBuddy is particularly useful if your question is, "What keywords can a channel of my size realistically compete for?" Its Keyword Explorer evaluates competition, search traffic, related terms and trends. www.tubebuddy.comsupport.vidiq.com

Semrush is worth considering if you want a more rigorous "competitors rank for X, but I don't" workflow. Its Keyword Gap tool explicitly identifies missing, weak and untapped keywords against up to five competitors—but it's fundamentally an SEO/web keyword tool rather than a YouTube-native research product. www.semrush.com

The workflow I'd use for your channel

Don't simply enter your channel and ask for "keyword ideas." Instead:

1. Pick 5–10 genuinely similar educational channels.

Ideally they're close to you in:

• subject
• target audience
• video length
• channel size

2. Find their "outlier" videos.

Look for videos that substantially outperform that channel's normal views. Those are often more valuable than their biggest evergreen videos.

3. Extract the underlying topics/questions.

For example, suppose you teach economics and competitors have successful videos around:

"Why Japan's economy stopped growing"

You don't necessarily want to make the same video. Look for the adjacent unanswered searches:

• Why did Japan's wages stagnate?
• Why does Japan have so much government debt?
• Why didn't Japan's lost decade end?
• Japan vs South Korea economic growth
• What would happen if Japan raised interest rates?

That's where the gap is.

4. Cross-check demand vs competition.

The ideal opportunity is:

Competitors have demonstrated audience interest + people search for the topic + relatively few strong videos answer it well + it's relevant to your audience.

That's much more useful than simply chasing keywords with high search volume.

One important distinction

There are actually three different kinds of gaps you can exploit:

Search gap:
People search for something, but there aren't many good videos.

Competitor coverage gap:
Your competitors cover a broader topic but neglect an important subtopic.

Audience-question gap:
People repeatedly ask questions in comments that the creator hasn't adequately answered.

The third can be particularly powerful for educational channels because it can reveal what people are confused about, rather than merely what they type into search. Some newer tools specifically analyze competitor comments for this purpose, although I'd treat those as supplementary rather than your primary SEO tool. onetube.io

If I had to choose one: start with vidIQ for competitor/topic discovery, then use TubeBuddy to validate whether the resulting ideas are realistically winnable for your channel. www.tubebuddy.comsupport.vidiq.com

If you tell me what your educational channel teaches + roughly how many subscribers you have, I can also show you exactly how I'd perform a competitor-gap analysis and what metrics I'd use to rank the opportunities.

Yes. If your goal is specifically “find keywords/topics that similar educational channels are getting traffic from, but I’m under-serving”, I’d prioritize these:

What I'd choose for your use case

Start with vidIQ if your channel is primarily YouTube. Its keyword tools provide estimated demand, competition, trends and related queries, while its competitor functionality helps you reverse-engineer what's working for comparable channels. vidiq.com

Add Semrush if you want a more rigorous content-gap analysis: e.g., Competitor A ranks/gets visibility for these topics → Competitor B does too → my channel doesn't cover them. Semrush is particularly useful when you want to analyze gaps at the topic/keyword level rather than simply generate ideas. onetube.io

TubeBuddy is a good alternative if you want the research tightly integrated into your YouTube workflow. Its Keyword Explorer evaluates search volume, competition and related terms, and it can surface keyword information while you're browsing YouTube. www.tubebuddy.com

But there's an important distinction

Don't just look for “keywords my competitors rank for.”

For an educational channel, I'd look for this much more valuable intersection:

Competitor demand + weak coverage + your expertise

For example:

3 competing channels repeatedly get views around “Bayes theorem explained”
↓
They don't cover “Bayes theorem with real-world medical examples”
↓
Search demand exists for related queries
↓
You can make a substantially better explanation
↓
That's a real content gap.

I'd also inspect comments on competitor videos. Viewers frequently reveal gaps by asking things like “Can you explain X?”, “What happens if Y?”, or “Can you do an example for Z?”—signals that conventional keyword tools don't capture very well. Some newer YouTube research tools are explicitly targeting this audience-question gap. onetube.io

My recommended stack

If I were building an educational channel today:

vidIQ → competitor discovery & YouTube keyword research
Semrush → systematic keyword/content-gap analysis
YouTube itself → autocomplete + competitor comments + actual SERPs
Google Trends → validate whether interest is growing or declining

And I wouldn't obsess over the exact search-volume numbers. YouTube doesn't expose true search volume publicly, so third-party tools are estimates; the relative opportunity is often more useful than the absolute number. wildandfreetools.com

If you tell me what your educational channel teaches (e.g. physics, coding, finance, history, medicine, language learning), I can also tell you exactly how I'd run a competitor keyword-gap analysis for that niche, including which 3–5 competing channels to benchmark.

Yes. If your goal is specifically “find keywords/topics that similar educational YouTube channels are getting traction from, but I’m not covering yet,” I’d prioritize these:

1. vidIQ — best overall for your use case

vidIQ is probably the first one I'd try. It combines keyword research, competitor research, trends, and content ideas. Its keyword research exposes search volume, competition, related terms, and questions; it also has competitor-oriented discovery features. support.vidiq.com

Best for: finding “competitors are getting views from these topics; which ones could I realistically pursue?”

2. TubeBuddy — best for keyword opportunity scoring

TubeBuddy's Keyword Explorer looks at competition, search traffic, related terms, and long-tail opportunities. Its advantage is that the research is tightly integrated with YouTube Studio. www.tubebuddy.com

Best for: validating whether a keyword is actually attainable for your channel rather than merely popular.

3. YouTube Gap Analyzer via Semrush — closest to literal “gap analysis”

This is particularly interesting for what you're asking. It analyzes the top videos for a keyword and looks for outdated information, low engagement, negative viewer sentiment, poor production quality, and underserved topics. www.semrush.com

Best for: finding “Here are weaknesses in the videos currently winning this search; make a better educational version.”

What I'd use for an educational channel

I'd actually combine vidIQ + YouTube Gap Analyzer:

Competitor channels → their high-performing topics → keyword variations → topics you don't cover → search/competition → weaknesses in existing videos → video ideas.

For example, imagine you teach statistics and three competing channels are getting unusual traction from:

“Bayes theorem explained with real examples”

You'd investigate adjacent searches such as:

• Bayes theorem for beginners
• Bayes theorem medical diagnosis
• Bayes theorem interview questions
• Bayesian thinking explained
• Bayes theorem without formulas

Then look for the intersection of demand + weak competition + a topic your audience actually wants.

One important distinction: a conventional keyword tool isn't necessarily a true content-gap tool. The strongest workflow is to compare your channel's topic coverage against several competitors, rather than simply finding keywords with high search volume. Current tool comparisons also note that vidIQ is particularly oriented toward competitor research/ideation, while TubeBuddy is stronger around optimization and workflow. monitoryt.com

If you give me your educational channel's niche + 3–5 competing channels, I can also show you exactly how I'd build a competitor keyword-gap matrix and what metrics I'd use to decide which gaps are worth making videos about.

Yes. If your goal is specifically “find topics/keywords that similar educational channels are missing, then make videos around those gaps,” I’d prioritize these:

My pick: vidIQ + YouTube Studio

vidIQ is particularly useful for this because its keyword research surfaces search volume, competition, related keywords, matching terms and questions, while its competitor-oriented features can help you see what similar creators are doing. support.vidiq.com

But there's an important distinction:

A “keyword gap” isn't necessarily a keyword with low competition.

For an educational channel, I'd look for:

Demand exists + competitors have weak coverage + you have a credible way to teach it better.

For example, suppose you're making videos about economics and three competing channels repeatedly cover:

• “What is inflation?”
• “How interest rates work”
• “Why recessions happen”

But their audiences repeatedly ask:

• “Why does raising interest rates actually lower inflation?”
• “Why didn't inflation fall immediately?”
• “How does inflation affect renters specifically?”

Those question-level gaps can be much more valuable than simply finding a keyword with a high score.

A good workflow

1. Pick 5–10 genuinely similar channels.
2. Put them into vidIQ's competitor research/tracking.
3. Identify their highest-performing videos relative to their normal performance, rather than just their videos with the most views.
4. Extract the topics, titles and recurring questions.
5. Expand each topic into long-tail searches using vidIQ/TubeBuddy.
6. Check YouTube autocomplete and your YouTube Studio → Analytics → Research data for evidence of audience demand.
7. Look at the first page of YouTube results manually.
8. Find places where existing videos are:
   • old,
   • overly broad,
   • poorly explained,
   • aimed at a different audience,
   • missing an obvious sub-question,
   • or getting lots of comments asking for clarification.
9. Score the resulting ideas by demand × gap × your authority × likely clickability.

TubeBuddy is particularly useful in step 5 because its Keyword Explorer provides search/competition data and a channel-specific perspective on keyword opportunity. www.tubebuddy.com

One tool I'd not rely on alone

Don't just enter your niche into a keyword tool and sort by “high volume / low competition.” That's likely to give you SEO opportunities, not necessarily content opportunities.

For an educational channel, I'd actually build a competitor content-gap matrix—competitor × topic × search demand × existing coverage × audience questions—and rank the gaps. That's much closer to what you're trying to accomplish.

If you give me your channel topic + 3–5 similar YouTube channels, I can show you exactly how I'd identify the gaps and what kinds of videos I'd prioritize.

For an educational YouTube channel, you want tools that reveal:

1. Keywords your competitors rank for that you don't
2. Topics viewers search for but competitors haven't covered well
3. Questions/comments your audience is asking
4. Video opportunities with high demand and lower competition

The best options are:

My recommended stack by channel size

New/small educational channel

• YouTube Studio (free)
• vidIQ free tier
• Google Trends
• AnswerThePublic

Goal: find underserved beginner questions.

Growing channel

• vidIQ or TubeBuddy
• Ahrefs or Semrush

Goal: find topics where competitors have traffic but weak coverage.

Serious education brand

• Ahrefs + Semrush
• YouTube analytics
• Comment mining (your competitors’ comments are often a goldmine)

The workflow I would use

1. Pick 5–10 similar channels.
2. Export their top-performing videos.
3. Look for patterns:
   • High views but few competing videos
   • Many comments asking follow-up questions
   • Videos older than 1–2 years that still get traffic
4. Use Ahrefs/Semrush-style gap analysis to find missing search terms. www.mqlmagnet.comwww.semrush.com
5. Create videos that are:
   • more beginner-friendly,
   • more current,
   • more specific,
   • or solve the next question viewers have.

For educational channels, the biggest wins often come from “subtopic gaps”, not just keywords. Example:

Competitors:

• “Python Tutorial for Beginners” (huge competition)

Gap opportunity:

• “Python Lists Explained Through 10 Real Data Problems”
• “Python Mistakes Beginners Make After Week 1”
• “Python Projects for High School Students”

Those narrower lessons are easier to rank and often attract more engaged learners.

If you tell me your education niche (math, coding, language learning, science, finance, etc.) and your target audience, I can suggest the exact tools + competitor-gap process for that niche.
