Yes. The closest fit is vidIQ, especially if you want niche/long-tail keywords your existing videos are already attracting. Its Top Search Terms for Your Channel shows the searches bringing viewers to your videos, while its keyword tools surface related and rising terms. vidIQ Help Center

But YouTube Studio itself is essential: each video's Reach tab shows the actual YouTube Search terms and the specific videos suggesting your video. Google Help Google Help

For your use case, I'd combine:

• YouTube Studio → actual queries + suggested-video sources.
• vidIQ → uncover adjacent/niche keywords and opportunities.
• TubeBuddy → keyword research and ranking analysis. TubeBuddy TubeBuddy

If you mean “show me obscure keywords my videos are already getting impressions/ranking for, including ones I never targeted”, I can point you to the tools/features specifically designed for that.

Yes. If you mean “show me the weird/niche queries that my existing videos are actually getting discovered from,” rather than generic keyword-volume tools, there are a few options.

Best fit for what you're describing

1. YouTube Studio — surprisingly useful, and free

For each video, go to Analytics → Reach → YouTube Search terms. YouTube shows the actual search terms viewers used when they found that video. It also separately shows Suggested videos, including the videos that referred viewers to yours. Google Help Google for Developers

This is the closest thing to ground truth because it's based on your actual traffic, not estimated keyword volume.

The limitation: YouTube doesn't give you a giant keyword-discovery database or necessarily expose every low-volume query.

2. vidIQ — probably the closest third-party fit

vidIQ has a Top Search Terms for Your Channel feature that summarizes search terms bringing viewers to your videos, including their contribution to views/watch time. It also has personalized Keywords For You based on your channel data. vidIQ Help Center

support.vidiq.com

That's more interesting for your use case than simply typing "my niche + keyword" into a keyword tool.

3. TubeBuddy — better for expanding what you discover

TubeBuddy's Keyword Explorer gives search/competition information and related keyword ideas, while Search Explorer lets you investigate keywords directly from YouTube search results. TubeBuddy TubeBuddy

tubebuddy.com

The important distinction

There are really two different datasets you're asking about:

And Suggested is fundamentally different from Search. YouTube says Suggested traffic comes from recommendations next to/after other videos, and its recommendation system uses signals including viewing/search history, clicks, watch time, and satisfaction—not simply keywords. Google Services

So if your goal is something like:

“My video unexpectedly started getting 2,000 views/day. Tell me the obscure searches and adjacent videos that are causing it, then find more topics I can exploit.”

I'd use YouTube Studio as the source of truth + vidIQ as the discovery layer.

If you tell me what kind of videos/channel you make, I can also show you a specific workflow for turning those hidden Search + Suggested terms into 10–20 new video ideas.

Yes. If you mean “What weird/niche phrases are my already-published videos actually getting discovered for?”, there are a few tools, but they differ quite a bit.

Best options

• YouTube Studio — the most authoritative starting point. Your video's Analytics can show the search terms generating traffic, while the newer Trends tab surfaces searches your audience is making and content gaps. Google Help vidIQ
• vidiq.com — probably the closest to what you're describing. It combines keyword research, search-performance data, related keywords, search volume, competition, and trend information. vidIQ vidIQ
• tubebuddy.com — particularly useful if you want to track where a video ranks for specific keywords. Its Rank Tracker monitors positions across YouTube and Google, while Search Explorer analyzes keywords directly from YouTube search results. TubeBuddy TubeBuddy

The important distinction

If you're after hidden opportunities, I'd look for a workflow like:

Your video → actual search queries → unusual/low-volume phrases → ranking position → related phrases → new video opportunities

That's more valuable than a generic keyword tool telling you that “fitness” has 500K searches.

For Suggested/Browse, though, there's an important caveat: YouTube doesn't give creators a clean list of “these are the keywords your video ranks for in Suggested.” Suggested traffic is recommendation-driven rather than a conventional keyword-ranking system. You can see the videos/sites sending traffic and recommendation-related analytics in Studio, but tools claiming to expose the exact “Suggested keywords” should be treated skeptically.

If you tell me what platform your videos are on (YouTube, TikTok, etc.), I can point you to the tool that gets closest to “show me every obscure query my recent videos are currently winning.”

Yes. If you mean “show me the weird/niche searches that my actual recent videos are already getting discovered for”, there are a few options.

Best options

• YouTube Studio itself — best source of truth. For each video, go to Analytics → Reach → YouTube Search terms. YouTube shows the actual searches that led viewers to the video. You can also see which specific videos are sending you Suggested Videos traffic. Google Help Google Help
• vidIQ — best third-party option for turning that data into keyword opportunities. Its “Top Search Terms for Your Channel” identifies search terms bringing viewers to your videos, while its keyword tools expand those into related/matching terms and rising keywords. vidIQ Help Center
• YouTube Studio Trends — better for finding what to make next. It surfaces searches from your audience, breakout videos, recent videos your audience watches, and content gaps. Google Help

The important distinction

If you're looking for something like:

Video published 5 days ago → 17 impressions from “how to _ without _” → currently ranking around #8 → also being suggested after these 6 videos → here are 20 adjacent low-competition queries

YouTube Studio gives you pieces of this, but doesn't really package it into that kind of “niche keyword discovery” report. Search-term data can also be incomplete because YouTube may suppress low-volume/one-off queries. Google Help

And Suggested Videos isn't really a keyword-ranking system. YouTube says Suggested/Up Next recommendations are personalized based heavily on what viewers are likely to watch next, whereas Search ranking considers relevance to the query plus engagement. Google Help

If you tell me what kind of videos/channel you have, I can recommend the best tool/workflow for specifically uncovering long-tail queries your videos are already accidentally ranking for—which is usually much more useful than generic keyword-volume tools.

Yes. If you mean “show me the weird/niche searches that are actually bringing viewers to my recent videos, plus what videos YouTube is putting me next to,” there are a few good options.

Best starting point: YouTube Studio

YouTube Studio itself gives you the underlying data:

• YouTube Search terms — the actual searches viewers used to discover each video.
• Suggested videos — the specific videos that generated suggested traffic to your video.
• Advanced Mode lets you drill into individual videos and traffic sources. Google Help Google Help

That's actually better than generic keyword tools for your question because it's first-party data from your own channel, rather than estimated search volume.

For surfacing niche opportunities: vidIQ

vidiq.com has a Keywords Research tool with things like:

• Top Search Terms for Your Channel — terms already bringing viewers to you.
• Keywords For You — opportunities based on your channel data.
• Rising Keywords — growing searches.
• Related/matching terms and questions. vidIQ Help Center

So if your goal is “I already rank/get discovered for this obscure thing—what adjacent obscure keywords should I make videos around?”, vidIQ is probably closer to what you're describing.

One important distinction

There isn't really a trustworthy tool that can tell you the exact keywords behind Suggested traffic in the same way it can for Search. Suggested is recommendation-driven: YouTube says Suggested videos are selected based on what viewers are likely to watch next, including the video they're currently watching and personalized watch history. Google Help

So I'd use:

YouTube Studio → actual search terms + suggested-video sources
→ vidIQ → expand those discoveries into related/niche keyword opportunities

Also, YouTube's Trends tab now surfaces top searches, audience interest, breakout videos, and content gaps based on your audience's recent behavior. Google Help

If you tell me what kind of videos/channel you make, I can recommend the best tool/workflow specifically for finding those “holy crap, I didn't know people searched for that” keywords.

Yes. If you mean “show me the weird/niche queries my already-published videos are actually getting discovered for, plus the videos that are feeding me Suggested traffic,” there are a few good options.

Best options

1. YouTube Studio — best source of truth, and free

For each video, go to Analytics → Reach. YouTube exposes:

• YouTube Search terms — the actual searches viewers used to find that video.
• Suggested videos — the specific videos that viewers watched before/around being served your video.
• Other discovery sources such as Browse/Home. support.google.comsupport.google.com

This is actually better than a generic keyword tool for your question because it's based on your video's real traffic, rather than estimated keyword volume.

YouTube's Advanced Mode also lets you drill into traffic-source rows and export/analyze the data. support.google.comsupport.google.com

2. vidIQ — best third-party layer

vidIQ has a Top Search Terms for Your Channel feature that surfaces the search terms actually bringing viewers to your videos, along with their contribution to views/watch time. It also has keyword research, related terms, rising keywords, and search-volume/competition estimates. support.vidiq.com

That's probably the closest to the tool you're describing if you want the data turned into something more actionable.

3. YouTube Studio Trends — useful for finding what to make next

The newer Trends tab shows what your audience is searching for, related recent videos, breakout content, and content gaps. It's more useful for finding the next opportunity than diagnosing exactly what a particular existing video is ranking for. support.google.com

One important distinction

YouTube doesn't really give you a clean “your video ranks #7 for this keyword” report. Its native analytics tells you the searches that generated traffic, while third-party tools can estimate search volume/competition. support.google.com

So if your goal is:

“Take my last 20 videos and surface obscure search queries + unexpected Suggested-video relationships that are already working, then tell me which ones I should make follow-ups around.”

YouTube Studio + vidIQ is a very good combination.

If you want, I can also point you to the specific tool that does this automatically across your whole channel rather than making you inspect videos one by one.

Yes. If you mean “show me the obscure queries that are already bringing people to my recent videos, plus the videos/topics YouTube is using to recommend them”, there are a few good options.

Best options

• YouTube Studio itself — actually the most authoritative source for your channel. For each video, Analytics → Reach → YouTube Search terms shows the searches that led viewers to that video. The same Reach area shows Suggested videos, i.e. the videos that viewers watched before/around yours through recommendations. Google Help Google Help
• vidiq.com — probably closest to what you're describing as a dedicated keyword-discovery tool. Its Top Search Terms for Your Channel uses your channel data to surface terms bringing viewers in, while Matching Terms can uncover more specific/niche variants. vidIQ Help Center vidIQ
• YouTube Studio Trends — useful for finding adjacent opportunities rather than just terms you're already ranking for. It shows searches related to your audience, breakout videos, and content gaps. Google Help

The important distinction

If your goal is “what weird/niche keywords are my videos already winning on?”, I'd start with YouTube Studio + vidIQ, rather than a generic keyword-volume tool.

A particularly useful workflow is:

Recent videos → Search terms → find low-volume/long-tail queries → group them by topic → check Suggested videos → make follow-up videos targeting the emerging cluster.

That's more actionable than simply looking for high-volume keywords, because YouTube says Search ranking considers relevance to the query plus engagement, while Suggested is personalized around what viewers are likely to watch next. Google Help

If you tell me what kind of videos you make, I can also point you to the tool that is best specifically for finding those “I didn't even realize people were searching for this” keywords.

Yes. If you mean “show me the weird/niche queries my existing videos are already getting discovered for, and the videos feeding me Suggested traffic,” there are a couple of good options.

Best fit: vidIQ

vidIQ is probably the closest off-the-shelf tool.

• Top Search Terms for Your Channel surfaces the actual search terms bringing viewers to your videos, including the less-obvious ones. support.vidiq.com
• It can show which videos rank for keywords and lets you track keyword positions over time. vidiq.comdevelopers.google.com
• Its keyword research can expand those terms into related/matching long-tail queries.
• For your particular use case, I'd use it less as a generic “keyword generator” and more as a mine-the-keywords-you're-already-winning-for tool.

YouTube Studio itself is surprisingly useful

You don't actually need a third-party tool to get the raw data.

In YouTube Studio → Analytics → Reach, YouTube exposes:

• YouTube Search terms — the specific queries that generated traffic.
• Suggested videos — the specific videos appearing as sources of Suggested traffic. support.google.com

Google's Analytics API confirms that the underlying data can return the top search terms for an individual video, including the terms that generated the most views. developers.google.com

The important distinction is that YouTube Studio tells you what is actually happening on your channel, whereas tools like vidIQ/TubeBuddy are better at helping you expand those discoveries into additional opportunities.

TubeBuddy is another option

TubeBuddy has Search Explorer and Search Positions/Rank Tracking, which can analyze search volume, competition and your ranking position for keywords. www.tubebuddy.com

For exactly what you're describing, I'd rank them:

1. YouTube Studio — best source of truth for actual queries and Suggested sources.
2. vidIQ — best for turning those discoveries into a systematic keyword-mining workflow.
3. TubeBuddy — strong if you specifically want rank tracking and SEO optimization.

If you tell me what kind of videos/channel you make, I can also show you a concrete workflow for finding the “why the hell is this video ranking for THAT?” keywords and turning them into your next 10 videos.

Yes. If you mean “show me the obscure queries that my already-published videos are actually getting discovered for, plus the videos that are feeding me Suggested traffic”, there are a few options.

Best options

• YouTube Studio itself — best source of truth. For each video, Analytics → Reach gives you:

• YouTube Search terms — the actual searches that led people to the video.
• Suggested videos — the specific videos that viewers were watching when your video was suggested. Google Help Google Help

You can also use Advanced Mode to drill into “YouTube Search” and see the individual search queries. Google Help

• vidiq.com — probably closest to what you're describing. Its Top Search Terms for Your Channel feature surfaces the search terms actually bringing viewers to your videos, including their contribution to views/watch time. It also has keyword/opportunity research and “Rising Keywords.” vidIQ Help Center
• YouTube Studio Trends is useful for the next layer: it shows searches associated with your audience, breakout videos, recently watched topics, and content gaps. It's more about discovering opportunities than reverse-engineering exactly what your existing videos rank for. Google Help

The important distinction

If your goal is niche keywords you didn't intentionally target, I'd prioritize YouTube Studio + vidIQ.

For example, you might discover:

Your video is about “best cameras for travel”

But it's actually getting Search traffic from:

• “best compact camera for Europe”
• “camera for walking tours”
• “small camera low light travel”
• “best camera under 500 for travel”

Those are often much more interesting than generic keyword-volume tools because they're validated by your own audience and video.

And for Suggested, YouTube Studio can tell you something like:

8.2% of traffic → Suggested Videos
→ Video A
→ Video B
→ Video C

That gives you a way to identify the topic clusters YouTube already associates your video with, rather than guessing from keyword tools. Google Help

One caveat: YouTube doesn't expose every tiny search query; low-volume/one-off searches can be omitted from Analytics. Google Help

If you're looking for a tool specifically built to turn this into a “hidden keywords my recent videos are winning” dashboard, I can also find the 3–5 best tools for that and compare them.

Yes. If you mean YouTube videos, there are tools that can uncover:

• Niche search keywords your existing videos already rank for
• Keywords driving impressions but not clicks
• Long-tail queries you’re close to ranking for
• Suggested videos / “watched next” opportunities
• Competitor videos your audience overlaps with

The best options:

For your specific use case (“my recent videos are ranking for niche keywords and suggested watch lists”), I’d do this:

1. Open YouTube Studio → Analytics → Reach
2. Check: - YouTube search terms → find unexpected phrases you’re already appearing for
3. Content suggesting this video → see which videos are feeding recommendations
4. Impressions from suggested videos → identify adjacent topics
5. Put those terms into vidIQ or TubeBuddy to expand them into: - related searches
6. lower-competition variations
7. follow-up video ideas vidIQ TubeBuddy

A particularly useful workflow is:

“Ranking but low views” keywords → make a follow-up video → link them together with end screens/playlists.

Those are often better opportunities than chasing completely new keywords because YouTube already has evidence your channel fits that audience.

If you mean TikTok, Instagram Reels, or Google video search rather than YouTube, the tool stack is different.

Yes. If you mean “show me the weird/niche queries that my existing videos are already getting discovered for”, rather than generic keyword research, there are a few options.

Best fits

• vidIQ — probably the closest match. Its Top Search Terms for Your Channel surfaces the search terms actually bringing viewers to your videos, including the views/watch time associated with those terms. It also has “Keywords For You” and rising keywords personalized to your channel. vidIQ Help Center

vidiq.com

• TubeBuddy — its current Recommended Tags feature incorporates the old Suggested Tags functionality, including information about how many views a video received through Search. Its Keyword Explorer also finds long-tail, lower-competition opportunities. TubeBuddy TubeBuddy

tubebuddy.com

• YouTube Studio itself — don't overlook this. Studio's Analytics/Reach data can show the actual search terms generating traffic, while the newer Trends tab lets you explore what viewers are searching for. Google Help

The important distinction

If you're specifically interested in Suggested/Browse discovery, that's harder. YouTube doesn't give you a clean list like:

“Your video is being suggested next to X because people interested in Y are watching it.”

Third-party tools tend to be much better at keyword/search research than exposing the underlying Suggested Videos recommendation graph.

For your use case, I'd want a workflow that takes your last 10–20 videos, finds:

1. obscure search queries already producing impressions/views,
2. queries where you're ranking surprisingly well,
3. long-tail variations around those queries,
4. videos/channels your videos are appearing alongside in Suggested,
5. recurring topics connecting those search + suggested signals,

…and then turns those into new video opportunities.

If that's what you're after, I can also tell you which tool currently does the closest job to that workflow and how I'd use it to mine your recent videos for “hidden” keywords.

Yes. If you mean “show me the weird/niche queries that my recent videos are actually getting discovered for, plus the videos/channels that are feeding me Suggested traffic”, there are a few options.

Best options

• YouTube Studio itself — surprisingly good for the actual data. For each video, go to Analytics → Reach:

• YouTube Search shows the specific searches that brought viewers to the video.
• Suggested videos shows the videos that viewers were watching when your video was suggested. Google Help Google Help
• Advanced Mode lets you drill into individual traffic sources and export the data. Google Help
• vidIQ — probably closest to what you're describing as a keyword discovery tool. Its Top Search Terms for Your Channel uses the search terms actually bringing viewers to your videos, while its keyword research also surfaces related/matching terms and rising searches. vidIQ Help Center

vidiq.com

• YouTube Trends — better for finding adjacent opportunities rather than telling you exactly what an existing video is ranking for. The current Trends tab includes audience searches, breakout videos, recent videos, and content gaps. Google Help

The important distinction

If you're specifically after:

“My video has 3,000 views. What obscure searches like ‘best X for Y’ or ‘how to Z without A’ are quietly sending me traffic, and what videos are causing YouTube to recommend me?”

YouTube Studio is the source of truth. Third-party tools can estimate search volume/opportunity, but they generally can't see your channel's private Suggested/Search attribution as completely as YouTube can.

And there's an interesting opportunity here: combine Search Terms + Suggested Videos for your last 10–20 videos, then identify clusters where a niche search query and a particular group of suggested videos overlap. That's much more useful than generic “keyword research.”

If that's what you're trying to do, I can show you the exact YouTube Studio workflow (or a tool that automates it) to surface those hidden/niche keywords from your recent videos. Google Help

Yes. If you mean “what weird/niche phrases are my existing videos actually getting discovered for?”, there are a few options—but they differ in how close they get to the exact thing you want.

Best options

• YouTube Studio Analytics — start here. Your video's Reach → YouTube search terms report shows the actual searches that generated traffic to your video. YouTube's newer Trends tab also surfaces searches from your audience and related content watched by them. Google Support Google Support
• vidIQ — probably the closest third-party tool to what you're describing. It has Top Search Terms for Your Channel, which summarizes the search terms bringing viewers to your videos, plus keyword discovery, rising keywords, and related terms. vidIQ Help Center vidIQ
• TubeBuddy — stronger as an all-around channel/SEO tool, with keyword research and competitor/search analysis, but I'd favor vidIQ for the particular “what terms are emerging around my channel?” use case. vidIQ

The important distinction

If you're trying to uncover unexpected long-tail keywords like:

“best cheap ___ for beginners”
“___ problem after 3 months”
“why does _ do _”

that your videos are already getting impressions/rankings for, YouTube Studio's actual search-term data is the gold mine. Third-party keyword tools are better at estimating what you could rank for.

For Suggested/Browse, though, there isn't an equivalent clean “these are the keywords you're ranking for” report because Suggested isn't fundamentally keyword-ranked the way Search is. You want to look at Traffic source → Suggested videos and identify the videos/topics that are feeding impressions to yours, then extract recurring topical patterns.

If you tell me what kind of videos you make, I can also recommend the best tool/workflow specifically for uncovering low-volume, high-intent “hidden” keywords from your last 10–20 videos.

Yes — YouTube Studio itself is the first place I’d look, and there are third-party tools that go further.

• YouTube Studio → Analytics → Content/Reach: For each video, YouTube exposes the actual search terms viewers used to find it and the specific videos that suggested your video. Google Help Google Help
• vidIQ: Probably the closest match to what you're describing. Its Channel Audit surfaces top search terms your channel is associated with and top videos suggesting your content. Its keyword tools also identify related/matching terms and search-volume/competition estimates. vidIQ Help Center vidIQ Help Center
• TubeBuddy: Stronger for keyword research and SEO optimization, with keyword competition/search-traffic data, but it's less directly focused on uncovering the unexpected queries your existing videos are already winning. TubeBuddy TubeBuddy

The distinction that matters

If you mean:

“Show me weird/niche searches that my last 10 videos are already getting impressions/views from, especially terms I didn't intentionally target.”

Then YouTube Studio + vidIQ is the combination I'd use.

YouTube gives you the first-party data: search query → your video and suggesting video → your video. Google Help

Then you can look for patterns like:

Video A → 37 searches for “best budget X for Y”
Video B → 19 searches for “X vs Y for beginners”
Video C → 11 searches for “how to X without Y”

Those unexpected, low-volume queries that are already converting into views are often much more valuable for your next videos than generic keyword-volume tools.

One caveat: Suggested Videos aren't really “keywords.” YouTube identifies the videos that are driving suggested traffic; recommendation ranking is personalized and based heavily on viewer behavior, relevance, and satisfaction. webfiddle.net developers.google.com

If you tell me what kind of videos you make, I can also point you to the tool/workflow that is best specifically for finding “hidden keywords + suggested-video opportunities” from your recent uploads.

Yes. For YouTube specifically, there are tools that can help uncover:

• niche keywords your existing videos already rank for
• search terms driving impressions/views
• keywords where you’re close to ranking higher
• videos appearing in Suggested alongside yours
• content gaps your competitors are capturing

The closest matches:

For your exact use case — “my recent videos are ranking for unexpected niche keywords and suggested watch lists” — I’d do this workflow:

1. Open YouTube Studio → Analytics → Reach

• Look at: - “YouTube search terms”
• “Suggested videos”
• “Content suggesting this video”
• Run your best-performing recent videos through vidIQ or TubeBuddy

• Look for: - keywords you rank on page 1–3 for
• phrases with low competition
• related videos that repeatedly appear beside yours
• Create a “keyword harvesting” spreadsheet:

• Keyword
• Current ranking position
• Video ranking
• Monthly impressions
• Suggested videos appearing next to you
• Next video idea

A lot of creators miss this: the best opportunities are often not the keywords you targeted. A video about “budget cameras” might quietly start ranking for something like “best webcam under $50 for Zoom” — and that unexpected phrase can become your next video.

If you mean YouTube specifically, I’d lean toward vidIQ + YouTube Studio for discovery, and TubeBuddy if you want more structured rank tracking. vidIQ TubeBuddy

If you mean TikTok, Instagram Reels, or Google search traffic from videos, the tool stack is different.

Yes. If you mean “show me the weird/niche queries that my existing videos are actually getting discovered for, plus what videos are feeding me Suggested traffic”, there are a few options.

Best options

• YouTube Studio itself — best source of truth. For each video, go to Analytics → Reach. YouTube exposes:

• YouTube Search terms — the actual searches that led viewers to the video.
• Suggested videos — the specific videos that were watched before/around yours through Suggested. Google Help Google Help

The catch: YouTube can suppress low-volume/one-off search queries, so you won't necessarily see every long-tail keyword. Google Help

• vidiq.com — probably closest to what you're describing. Its Top Search Terms for Your Channel feature summarizes the search terms actually bringing viewers to your videos, including their contribution to views/watch time. It also has keyword discovery, related terms, rising keywords, etc. vidIQ Help Center
• TubeBuddy is another option for keyword research and optimization, but I'd distinguish it from the specific use case you're describing: finding unexpected queries you're already ranking for. For that, I'd start with YouTube Studio + vidIQ rather than treating a generic keyword-volume tool as the answer.

One important distinction

There isn't really a tool that can reliably tell you “your video ranks #7 for these 47 tiny keywords” across YouTube in the way an SEO tool can do for Google.

YouTube's own data is more useful for answering:

“What searches are already sending people to this video?”

And Suggested is a different beast: YouTube recommends videos based on viewer behavior and predicted satisfaction, not simply a keyword match. Google Help Google Help

If your goal is finding “hidden niches” from your recent uploads, I'd actually use the data like this:

Recent videos → Search terms → cluster unexpected queries → check Suggested videos → identify the topic intersection → make follow-up videos

That can uncover much more interesting opportunities than conventional keyword-volume research.

If you tell me whether you're doing long-form YouTube, Shorts, or both, I can recommend the best tool/workflow specifically for surfacing those hidden ranking opportunities.

Yes. If you mean “show me the obscure/niche queries that my existing videos are already getting discovered for”, there are a few options—but they differ a lot.

Best options

• YouTube Studio itself — best source of truth.

For each video, go to Analytics → Reach → YouTube Search terms. YouTube shows the actual searches viewers used to find that video. You can also see which specific videos are sending you Suggested traffic. Google Help Google Help
This is the closest thing to what you're describing because it's based on your actual traffic, rather than estimated keyword volume.

• vidiq.com — best third-party option.

Its Top Search Terms for Your Channel feature surfaces the search terms bringing viewers to your videos and lets you see their contribution to views/watch time. It also has Keywords For You, which identifies opportunities based on your channel data, plus related/matching keywords and questions. vidIQ Help Center

• YouTube Studio Trends — best for finding the next niche topic.

The newer Trends tab shows searches from your audience, breakout videos, recently watched topics, and content gaps. It's more about opportunity discovery than reverse-engineering exactly what your existing videos are unexpectedly ranking for. Google Help

The important distinction

What you're describing is really a “keyword mining from my winners” workflow:

Recent video → actual search queries → low-volume/niche queries → check whether video ranks → find related queries → identify Suggested-video clusters → turn those into new videos.

YouTube gives you the actual search terms and Suggested-video sources, while vidIQ adds more keyword expansion/research around them. YouTube also explicitly says Search ranking considers how well the title, description and video content match the query, so these unexpected queries can reveal topics YouTube has associated with your video beyond the obvious title keyword. Google Help

If you want, I can also point you to the tool that gets closest to automatically doing this across your last 10–50 videos and spits out a ranked list of “you’re already getting impressions for these niche keywords” opportunities.

Yes. If you mean “show me the weird/niche queries that my already-published videos are actually getting discovered for”, there are a few options—but they differ a lot.

Best starting point: YouTube Studio itself

YouTube now exposes this natively:

• Search terms: In a video's Analytics → Reach, YouTube Search shows the actual terms viewers searched before finding your video. Google Help Google Help
• Suggested videos: The same Reach area shows which videos are sending you traffic through Suggested videos. Google Help
• Trends: YouTube Studio's newer Trends tab can surface what your audience is searching for, breakout videos, recent videos, and content gaps. Google Help

The limitation is that Studio isn't really designed as a “find all the hidden long-tail opportunities across my newest videos” tool.

Third-party option: vidIQ

vidiq.com is probably closest to what you're describing.

Its Top Search Terms for Your Channel feature specifically summarizes search terms that are bringing viewers to your videos and lets you see their contribution to views/watch time. vidIQ Help Center

It also has keyword discovery around related terms, matching terms, questions, search volume, competition, and rising keywords. vidIQ Help Center

The important distinction

If your goal is:

“My last 20 videos are getting impressions from searches/being suggested alongside unexpected videos. Tell me the niche topics/phrases emerging from that data.”

That's a more specialized workflow. YouTube gives you the underlying search terms + suggested-video sources, but it doesn't give you a great automatic “niche keyword mining” layer on top.

And Suggested isn't really keyword-driven in the same way Search is. YouTube says Suggested is personalized around what viewers are likely to watch next and what videos are often watched together. Google Help

So I'd separate the opportunity into:

Search mining:
actual query → your video → views/watch time → emerging long-tail keyword

Suggested mining:
video sending traffic → your video → shared topic/audience → niche topic cluster

If you tell me what kind of YouTube channel you have, I can recommend the best tool/workflow for specifically mining those unexpected ranking queries and Suggested-video niches rather than generic keyword-volume tools.

Yes. If you mean “show me the hidden/niche queries my existing videos are already getting impressions or suggested traffic from”, there are a few tools — but the best source is actually YouTube’s own data.

Best options

1. YouTube Studio (free, most accurate)

Go to:

YouTube Studio → Analytics → Reach → Traffic source: YouTube Search

You’ll see:

• Exact search terms people typed that led to your videos
• Impressions from those searches
• CTR
• Views
• Watch time

This is the closest thing to “keywords my videos are already ranking for.”

For suggested videos:

YouTube Studio → Analytics → Reach → Traffic source: Suggested videos

You can see:

• Which videos are recommending yours
• Which topics YouTube associates with your content
• Where your suggested traffic is coming from

The limitation: YouTube does not reveal every query (some are hidden due to privacy thresholds).

2. vidiq.com

Good for finding:

• Long-tail keywords
• Rising search terms
• Keyword difficulty vs opportunity
• Competitor keyword ideas

It also has ranking tools that let you check whether videos appear for specific searches. vidIQ

Best use case:

“My video is about X. What smaller phrases are people searching that I could make follow-ups around?”

3. tubebuddy.com

Useful for:

• Keyword discovery
• Search volume estimates
• Competition scoring
• Rank tracking

Its Search Explorer and Keyword Explorer features are designed around finding lower-competition YouTube search opportunities. TubeBuddy TubeBuddy

Best use case:

“Which keywords could I target next that are realistic for my channel size?”

4. search.google.com (if you have a website)

Helpful if your videos are also appearing in Google:

• “video” search queries
• Google Discover traffic
• Embedded video traffic

For “niche keywords my videos are already winning”

My preferred workflow:

1. Export your last 90 days from YouTube Studio → Reach
2. Sort search terms by: - High impressions
3. Good CTR
4. Low views relative to impressions (opportunity)
5. Look for patterns: - Specific problems
6. Product names
7. “how to” phrases
8. Comparisons
9. Beginner questions
10. Use vidIQ/TubeBuddy to expand those into related keywords.

Example:

Your video ranks for:

“best camera settings for indoor basketball”

Hidden opportunities:

• “basketball gym low light camera settings”
• “120fps basketball video settings”
• “iphone basketball filming settings”

Those smaller phrases often become better follow-up videos because YouTube has already shown your channel has relevance there.

If you mean TikTok, Instagram Reels, or YouTube Shorts rather than long-form YouTube, the tooling is different.

Yes. If you mean “show me the weird/niche queries that are actually bringing viewers to my recent videos, plus the videos that are feeding me Suggested traffic”, there are a few ways to do this.

Best starting point: YouTube Studio

YouTube already exposes both pieces at the individual-video level:

• Search: Video → Analytics → Reach → YouTube search terms shows the searches viewers used when they found that video. Google Help Google Help
• Suggested: Video → Analytics → Reach → Content suggesting this video shows the specific videos from which viewers reached your video via recommendations. Google Help
• You can use Advanced Mode to dig deeper, compare videos, and export analytics. Google Help Google Help

The catch is that YouTube doesn't expose every tiny search query—low-volume/one-off terms may be omitted from the report. Google Help

If you want an actual “niche keyword discovery” tool

Tools such as vidIQ and TubeBuddy are useful for keyword research, but there's an important distinction: they generally help you find opportunities, whereas YouTube Studio tells you what is actually happening to your videos.

For the specific workflow you're describing, I'd prioritize first-party YouTube data and build a layer on top of it:

Recent video → actual search queries → low-volume/niche queries → related suggested videos → recurring topic clusters → new video opportunities

YouTube's newer Trends tab is also worth checking. It surfaces searches based on your audience, related videos, breakout content, and content gaps. Google Help

If you're asking because you want a tool that automatically scans your channel and says “these 17 obscure keywords are emerging across your last 10 videos, and these 8 videos are driving Suggested traffic”, that's a more specific product—and I can look for the best tool that does exactly that.

Yes. There are a few tools that get close to exactly this, but they differ in how deeply they expose your own video's actual discovery data.

Best options

• YouTube Studio — actually the best starting point. For each recent video, Analytics → Reach shows:

• the specific YouTube search terms that generated traffic
• the videos that suggested your video
• other traffic sources

YouTube explicitly exposes both reports in the Reach tab. Google Help Google Help

• vidiq.com — probably the closest third-party tool to what you're describing. Its Keyword Research tool has “Top Search Terms for Your Channel,” which identifies search terms bringing viewers to your videos, plus related/matching terms and rising keywords. vidIQ Help Center
• YouTube Studio Trends — useful for going beyond terms you're already ranking for. It surfaces searches your audience is making, breakout videos, recent videos, and content gaps. The current Studio rollout is being updated in 2026. Google Help

The important distinction

If by “niche keywords my recent videos are ranking for” you mean:

“Show me weird, low-volume search phrases that this specific video is already getting impressions/views from, even though I didn't target those phrases.”

YouTube Studio is the authoritative source. Third-party keyword tools generally estimate search demand/opportunity; they don't have the same access to your video's private search-query data.

And for Suggested, you're looking for a slightly different signal. Rather than keywords, YouTube Studio can show you the specific videos sending viewers to yours via Suggested Videos. Google Help

If you want, I can also point you to a tool/workflow that automatically mines your last 10–50 videos for those long-tail search terms + suggested-video relationships and turns them into new video ideas.

Yes. For YouTube specifically, there are tools that can help surface long-tail/niche keywords your existing videos are already appearing for, plus opportunities from Suggested Videos and related content.

The closest matches:

• vidiq.com — Good for discovering keywords, tracking rankings, and finding content opportunities. It can help identify search terms around your niche and suggest topics based on your channel data. vidIQ vidIQ
• tubebuddy.com — Strong for YouTube SEO workflows: keyword discovery, rank tracking, competitor analysis, and optimization suggestions. TubeBuddy TubeBuddy
• search.google.com — If your videos are indexed in Google, it can reveal actual search queries driving impressions/clicks (more useful for Google search than YouTube Suggested).
• studio.youtube.com — The native source. Go to: - Analytics → Reach → YouTube Search terms (what people typed)
• Analytics → Reach → Traffic source: Suggested videos (which videos are sending viewers)
• Advanced mode → filter by video to compare winners

For the specific thing you described — “what weird/niche phrases are my recent videos already ranking for?” — I’d look for a workflow like:

1. Export your last 10–50 videos from YouTube Studio.
2. Put the videos into vidIQ/TubeBuddy rank tracking.
3. Look for: - keywords where you rank positions ~5–30 (easy wins)
4. unexpected long-tail phrases with low competition
5. suggested-video neighbors that repeatedly appear
6. Make follow-up videos targeting those exact clusters.

A more advanced option is to analyze your own channel data with the YouTube Analytics API and build a keyword map from:

• search terms
• suggested video sources
• retention by traffic source
• subscriber conversion by query

One caveat: YouTube does not expose a complete list of every keyword your videos rank for, so third-party tools are estimates or based on tracked keywords. The most accurate data about your actual viewers comes from YouTube Studio. vidIQ TubeBuddy

If you mean YouTube specifically, TikTok, or Google Search video results, the best tool stack changes.

Yes — but there’s an important distinction between “keywords my videos are actually getting found for” and “keywords I might rank for.”

Best option: YouTube Studio itself

For your actual recent videos, YouTube Studio gives you the first-party data:

• YouTube Search terms — the specific searches that led viewers to each video.
• Suggested videos — the specific videos that were recommending your video.
• Both are available under a video's Analytics → Reach reports. Google Help Google Help

YouTube does limit/omit very low-volume search terms, so you won't necessarily get every query someone typed. Google Help

If you want a tool that surfaces the niche opportunities automatically

vidIQ is probably closest to what you're describing. Its Top Search Terms for Your Channel identifies terms actually bringing viewers to your videos, while its keyword tools surface related/niche terms, search volume, competition, and rising searches. vidIQ Help Center vidIQ

It also has a rank checker where you can give it a video + keyword and see where that video currently appears in YouTube search. vidIQ

vidiq.com

The really interesting workflow

If your goal is “find weird/niche keywords my recent videos are already accidentally winning on”, I'd do:

Recent videos → actual Search terms → filter for low-volume/long-tail queries → compare which ones generated disproportionately good views/watch time → identify related terms → check rankings → make follow-up videos around the winners.

For Suggested, use the videos appearing in Content suggesting this video as a separate signal. That can reveal a different kind of niche: the topics/videos YouTube thinks your content belongs beside, rather than what people explicitly searched. Google Help

YouTube's own Trends tab is also useful for expanding those discoveries into related searches and emerging topics. Google Help

If you tell me what kind of videos you make, I can point you to the tool/workflow that's best for finding those unexpected long-tail rankings, rather than generic keyword research.

Yes. If you mean “show me the weird/niche queries my videos are actually getting discovered for right now,” there are a few options, but they differ quite a bit.

Best fit: YouTube Studio + vidIQ

YouTube Studio itself is the source of truth for this. For each video, go to Analytics → Reach → YouTube Search terms. It shows the actual searches viewers used to find that video. You can also see the specific videos sending you traffic under Suggested videos. Google Help Google Help

support.google.com

Then vidIQ is probably the closest third-party tool to what you're describing. Its Top Search Terms for Your Channel surfaces search terms actually bringing viewers to your videos, including their contribution to views/watch time. It also has personalized keyword opportunities based on your channel data. vidIQ Help Center

vidiq.com

For actual ranking positions: TubeBuddy

TubeBuddy is stronger if by “ranking” you specifically mean:

“My video is currently #7 for weird niche phrase.”

Its Rank Tracker monitors video positions for specified keywords, while Keyword Explorer helps find related/long-tail terms. TubeBuddy TubeBuddy

tubebuddy.com

The important distinction

There are really three different datasets:

YouTube's own Analytics API confirms that YouTube Search can expose the associated search term, while Suggested Videos identifies the referring video. Google for Developers Google for Developers

If your goal is specifically “mine the gold hidden in my recent videos”, I'd use YouTube Studio first, then vidIQ. The interesting stuff isn't necessarily high-volume keywords—it's often the bizarre 3–8 word queries where you already have evidence that YouTube is willing to surface your video.

If you tell me whether you're talking about long-form videos or Shorts, I can also tell you exactly where I'd look and what metrics I'd pull to find those “accidental rankings.”

Yes — but there’s an important distinction between “keywords your videos are actually getting discovered for” and “keywords a tool thinks you could rank for.”

Best options

• YouTube Studio itself is the best source for actual ranking/discovery data. For each video, go to Analytics → Reach → YouTube Search terms. It shows the search terms viewers actually used to find that video. You can also see the specific videos sending traffic through Suggested videos. Google Support Google Support
• vidiq.com is probably closest to what you're describing. Its Top Search Terms for Your Channel surfaces search terms bringing viewers to your videos and connects them to views/watch time. It also has keyword/ranking tracking. vidIQ Help Center vidIQ
• tubebuddy.com is stronger for keyword research and rank tracking. Its Keyword Explorer provides search volume, competition, trends, and related terms, while its SEO tools focus on improving search visibility. TubeBuddy TubeBuddy

For your specific use case

If what you want is something like:

“Take my last 20 videos and tell me the weird/niche searches I'm already appearing for, which ones I'm ranking for, and which suggested-video ecosystems I'm getting pulled into.”

I'd lean vidIQ + YouTube Studio.

The really valuable data isn't just high-volume keywords. It's the unexpected queries where you're already getting impressions/views. Those can reveal little topic clusters you didn't intentionally target.

For Suggested, YouTube Studio is especially useful because it tells you which videos are actually recommending your video; third-party keyword tools generally can't give you an equivalent authoritative list of your video's actual suggested-video traffic. Google Support

If you tell me whether you're doing long-form, Shorts, or both, I can point you to the tool/workflow that gets closest to an “unexpected keywords + suggested-video opportunities” dashboard.

Yes. If you mean “show me the weird/niche queries that my existing videos are already getting discovered for”, there are a few options—but they differ a lot.

Best options

• YouTube Studio itself — best source of truth.

For each video, go to Analytics → Reach → YouTube Search terms. YouTube shows the actual terms viewers searched when they found that video. It also gives you “Content suggesting this video,” which shows the videos that generated Suggested traffic. Google Help Google Help
support.google.com

• vidIQ — probably closest to what you're describing.

Its Top Search Terms for Your Channel surfaces search terms actually bringing viewers to your videos, while its keyword tools expand those into related/niche terms. It also has Rising Keywords for emerging searches. vidIQ Help Center
support.vidiq.com

• YouTube Studio Trends — useful for finding the next niche opportunity.

The Trends tab shows what your audience is searching for, breakout videos, recent videos, and content gaps. It's more about discovering opportunities than reverse-engineering exactly why an existing video is ranking. Google Help

The important distinction

If your goal is:

“Video X is unexpectedly getting traffic. What obscure searches and adjacent videos are YouTube associating with it?”

I'd use YouTube Studio + vidIQ together.

YouTube gives you the actual first-party search/suggested traffic data. vidIQ can then help expand those terms into related long-tail keywords, search volume, competition, and emerging variants. Google Help vidIQ Help Center

One caveat: Suggested isn't really keyword ranking in the same way Search is. YouTube says Suggested/Up Next is personalized and heavily driven by what viewers are likely to watch next, whereas Search ranking considers relevance to the query plus engagement. Google Help Google Help

If you tell me what kind of videos/channel you have, I can also point you to the tool that is best specifically for finding those “I didn't even realize people searched for this” keywords.

Yes. If you mean “show me the weird/niche queries my existing videos are already getting discovered for, plus what videos are feeding me Suggested traffic,” there are a few good options:

Best options

1. YouTube Studio — best source of truth
For each video, go to Analytics → Reach. YouTube exposes:

• YouTube Search terms — the actual searches that led people to your video.
• Content suggesting this video — the specific videos that sent you Suggested traffic. support.google.com

This is the most valuable data because it's your actual audience behavior, rather than an estimated keyword database.

2. vidIQ — best for turning that data into keyword opportunities
vidIQ has Top Search Terms for Your Channel, which surfaces the search terms bringing viewers to your videos, along with their contribution to views/watch time. It also has keyword research, rising keywords, related terms, and rank tracking. support.vidiq.com

This is probably closest to what you're describing if you want something that says:

“Your video is unexpectedly getting discovered for these 17 low-volume queries. Here are the related niches you could make another video about.”

3. TubeBuddy — good for search/ranking investigation
TubeBuddy Search Explorer analyzes YouTube search results for keyword score, volume, competition, and the videos/channels ranking for the query. www.tubebuddy.com

One important distinction

Most third-party keyword tools are primarily keyword research tools. They don't necessarily tell you the full long tail of queries your particular video is organically appearing for.

For that, YouTube Studio is the underlying goldmine. YouTube's analytics API actually identifies YT_SEARCH traffic with the search term that generated the view. developers.google.com

And Suggested is a different beast: YouTube can tell you which videos are suggesting yours, but there isn't an equivalent public “keywords you're ranking for in Suggested” report because Suggested isn't fundamentally keyword-ranked like Search.

If you're trying to find “hidden niches” from your existing videos, I'd use YouTube Studio + vidIQ together. Studio finds the actual accidental winners; vidIQ helps expand those winners into related keywords/topics.

If you tell me whether you're doing long-form, Shorts, or both, I can also point you to the tool/workflow that's best specifically for finding those unexpected ranking queries.

Yes. If you mean “show me the weird, specific queries my existing videos are already getting discovered for”, there are a few options—but they differ quite a bit.

Best fit: vidIQ

vidIQ is probably the closest to what you're describing.

• Top Search Terms for Your Channel shows the actual search terms bringing viewers to your videos, including their contribution to views/watch time. support.vidiq.comdevelopers.google.comwww.tubebuddy.com
• Its keyword tools can then expand those terms into related/long-tail keywords, search volume, competition, and trends. support.vidiq.comvidiq.com
• It also has keyword/rank tracking, so you can monitor whether a video is actually moving for a particular query. support.vidiq.comvidiq.com

For the Suggested side

This is where things get trickier. YouTube itself gives you the most useful first-party data: in Studio → Analytics → Content/Reach, you can see which specific videos are sending you traffic through Suggested Videos. YouTube explicitly exposes this as a traffic-source detail. support.google.com

But Suggested isn't really keyword-driven in the same clean way Search is. A better analysis is:

Search: “What exact queries are already causing my videos to appear?”
Suggested: “What videos/audiences is YouTube already associating my video with?”

You can actually pull the Search terms programmatically through the YouTube Analytics API; Google's own example retrieves the top search terms generating views for a specific video. developers.google.com

TubeBuddy is another option

TubeBuddy has Keyword Explorer and Rank Tracker for researching and tracking YouTube rankings. www.tubebuddy.com

If your goal is specifically “find the obscure keywords my recent videos are already winning on, then turn those into more videos,” I'd lean vidIQ + native YouTube Analytics rather than generic keyword research.

If you tell me whether you're talking about YouTube long-form, Shorts, or both, I can also point you to the tool that gets closest to surfacing “you got 37 views from this oddly specific query, and you're ranking #4 for it” automatically.

Yes. If you mean “show me the weird/niche queries that my existing videos are actually getting discovered from, plus what videos are feeding me Suggested traffic”, there are tools for that—but they differ in how deeply they surface the data.

Best options

1. YouTube Studio — best source for your actual data

For each video, go to Analytics → Reach. YouTube gives you:

• YouTube Search terms — the actual searches viewers used to find that video.
• Suggested videos — the specific videos that sent viewers to yours.
• Impressions, CTR, watch time, etc. alongside those traffic sources. support.google.com

This is the most valuable data because it's your real traffic, rather than an SEO tool estimating search volume.

The catch: YouTube's native interface isn't particularly good at turning those discoveries into a big, searchable list of long-tail/niche opportunities.

2. vidIQ — probably closest to what you're describing

vidIQ has a Top Search Terms for Your Channel feature that identifies the search terms actually bringing viewers to your videos and shows their contribution to views/watch time. It also has Keywords For You and Rising Keywords for finding adjacent opportunities. support.vidiq.com

Its keyword research can then expand a discovered phrase into related keywords, matching terms and questions. support.vidiq.com

3. TubeBuddy — better for expanding discovered keywords

TubeBuddy's Keyword Explorer is useful once you've found a promising phrase. It can surface related/long-tail keywords and assess competition/search opportunity. www.tubebuddy.com

But there's an important distinction

If your goal is something like:

“My latest 20 videos are unexpectedly getting traffic for these 73 obscure searches. Find the patterns, group them into topics, tell me which ones I'm already ranking for, and identify videos I should make next.”

YouTube Studio + an analysis layer is what I'd use. vidIQ gets partway there, but the really interesting insight is in combining:

actual Search terms → Suggested-video sources → video/topic → views/watch time → emerging keyword clusters

YouTube itself confirms that Search and Suggested are separate traffic sources and lets you inspect the specific terms/videos behind them. support.google.com

If that's specifically what you're trying to do, I can also recommend the best tool/workflow for automatically mining your last 10–50 videos for those “you didn't know you ranked for this” keywords.

Yes. If you mean “show me the weird/niche queries that my actual recent videos are already getting discovered for”, there are a few options—but they differ a lot in how deeply they expose the data.

Best options

1. YouTube Studio — best source of truth
For each video, go to Analytics → Reach → YouTube Search terms. YouTube explicitly exposes the terms viewers searched when they found that video. It also separately shows Content suggesting this video, including the videos that generated Suggested traffic. support.google.com

The limitation: YouTube doesn't really turn this into a sophisticated “niche keyword opportunities across my last 20 videos” dashboard.

2. vidIQ — probably closest to what you're describing
vidIQ's current keyword tools include Top Search Terms for Your Channel, which summarizes search terms actually bringing viewers to your videos and associates them with views/watch time. It also has channel-specific keyword opportunities and rising keywords. support.vidiq.com

That's particularly useful for finding things like:

“I made a video about X, but YouTube is unexpectedly sending me traffic for X for beginners with Y.”

Those unexpected long-tail queries are often more interesting than generic keyword-volume tools.

3. YouTube Studio Trends — good for finding the next niche
YouTube's newer Trends tab shows what your audience and viewers across YouTube are searching for, including top searches over the last 28 days. support.google.com

One important distinction

There isn't really a legitimate tool that can tell you the exact “keywords” behind Suggested Videos in the same way Search terms can. Suggested isn't fundamentally keyword-driven. YouTube says Suggested/Up Next is based on what a viewer is likely to watch next, using signals such as viewing behavior and the video they're currently watching. support.google.com

So I'd think of the data as:

Search
→ What specific queries are people using to find my videos?

Suggested
→ Which videos/topics is YouTube associating my videos with?

And the second one can be extremely valuable for niche discovery even though it isn't technically a keyword report.

If you're specifically looking for a tool that will take your last ~10–50 videos and automatically surface the obscure search phrases + the videos you're being suggested beside + identify emerging topic clusters, I can point you to the closest tools for that workflow.

Yes. If you mean “show me the weird/niche queries my existing videos are already getting discovered for, plus what videos are feeding them through Suggested”, there are a few options:

Best starting point: YouTube Studio

YouTube already exposes this data for your own channel:

• YouTube Search → search terms: shows the actual terms viewers searched that led to your video.
• Suggested Videos → specific referring videos: shows which videos are sending viewers to yours.
• You can get to these under YouTube Studio → Content → select video → Analytics → Reach. support.google.com

This is actually better than generic keyword tools for your question because it's first-party data about what your videos are already ranking/discovering for, rather than estimated keyword volume.

If you want it surfaced/organized automatically: vidIQ

vidIQ is probably the closest fit.

Its Top Search Terms for Your Channel feature identifies search terms actually bringing viewers to your videos and shows their contribution to views/watch time. It also has Keywords For You and Rising Keywords for finding adjacent opportunities. support.vidiq.com

The particularly useful workflow is:

Your actual search terms → obscure/niche variations → related keywords → new videos

For ranking/SEO tracking: TubeBuddy

TubeBuddy has Keyword Explorer/Search Explorer, which is more focused on keyword scores, search volume, competition, and tracking rankings. www.tubebuddy.com

One important distinction: there isn't really a tool that can reliably tell you “your video is being suggested because of these exact keywords.” Suggested Videos isn't keyword-based in the same transparent way Search is. YouTube's own reporting identifies the specific videos that suggested yours, while Search reporting identifies the actual search terms. developers.google.com

If your goal is finding hidden/niche topics your existing videos are accidentally ranking for so you can make follow-up videos around them, I'd use YouTube Studio + vidIQ, rather than a generic keyword research tool.

Yes. If you mean “show me the obscure/niche searches that my existing videos are already getting discovered for”, there are a few options—but they differ quite a bit.

Best options

1. YouTube Studio — best source of truth
For each video, go to Analytics → Reach → YouTube Search terms. YouTube shows the actual search terms viewers used to find that video. You can also see the specific videos sending traffic through Suggested videos. support.google.com

The catch: YouTube doesn't really turn this into a sophisticated keyword-discovery database. It's more of an analytics report.

2. vidIQ — probably closest to what you're describing
vidIQ has Top Search Terms for Your Channel, which surfaces the search terms actually bringing viewers to your videos and associates them with views/watch time. It also has Keywords For You, which identifies opportunities based on your channel data, plus rising/matching keywords. support.vidiq.com

This is the one I'd investigate first if your goal is:

“Take my recent videos → find the weird long-tail queries they're already getting traction from → show me adjacent keywords I could make more videos around.”

3. TubeBuddy Keyword Explorer — better for keyword research
TubeBuddy is stronger for evaluating a keyword's search traffic, competition, and related terms. Its Opportunity Finder also analyzes individual videos for optimization opportunities. www.tubebuddy.com

One important distinction

Search keywords ≠ Suggested keywords.

YouTube gives you actual search terms for Search, but Suggested is fundamentally recommendation-driven. YouTube says Suggested videos are selected based on what viewers are likely to watch next and can be personalized based on watch history. support.vidiq.comwww.tubebuddy.comsupport.google.com

So for Suggested, I'd want a tool/workflow that answers:

“What videos are currently suggesting my video?” → “What topics/keywords do those videos collectively represent?” → “What adjacent videos should I make?”

YouTube Studio already gives you the first piece—the specific videos generating Suggested traffic. support.google.com

If that's specifically what you're after, I can also find you a tool that does the “reverse engineer my existing videos' Search + Suggested traffic into niche keyword opportunities” part. That's a narrower requirement than ordinary YouTube keyword research.

Yes. If by “niche keywords my recent videos are actually ranking for” you mean discovering unexpected long-tail terms that YouTube is already associating with your videos, there are a few options:

• YouTube Studio itself is the baseline. For each video, Analytics → Reach → YouTube Search terms shows the terms viewers searched that led them to your video. It also separately shows the videos that generated traffic through Suggested videos. support.google.com
• vidIQ goes further with Top Search Terms for Your Channel, which summarizes the searches bringing viewers to your videos and connects them to views/watch time. Its keyword tools also surface related and niche terms. support.vidiq.com
• TubeBuddy is stronger for rank tracking: you can monitor where your videos rank for keywords and combine that with Keyword Explorer/Search Explorer to find adjacent opportunities. www.tubebuddy.com

The important distinction

If your goal is specifically:

“Show me weird/low-volume keywords that my last 10–20 videos are already getting discovered for, then tell me which ones are worth making another video about.”

I'd lean vidIQ + YouTube Studio, rather than a generic keyword-research tool. YouTube Studio gives you the actual observed queries, while vidIQ can help expand those into related/rising terms. support.vidiq.com

For Suggested, there isn't really a clean “keywords you're ranking for” equivalent because Suggested is recommendation-driven rather than a conventional keyword-ranking system. YouTube does, however, expose the specific videos that are sending suggested traffic to yours. support.google.com

If you tell me what kind of videos/channel you make, I can also suggest the tool/workflow that best surfaces those hidden long-tail opportunities.

Yes. If you mean “show me the weird/niche queries my existing videos are actually getting discovered for, plus what videos are feeding me Suggested traffic”, there are a few options.

Best options

1. YouTube Studio — best source of truth

• Go to Video → Analytics → Reach.
• YouTube Search terms shows the actual searches that led viewers to that video.
• Content suggesting this video / Suggested videos shows which videos are sending you suggested traffic. support.google.com
• YouTube's Analytics API can also pull the top search terms for specific videos, so this data can be automated. developers.google.com

2. vidIQ — probably closest to what you're describing
vidIQ has Top Search Terms for Your Channel, which summarizes the search terms actually bringing viewers to your videos, including their contribution to views/watch time. It also has keyword opportunity/rising-keyword features. support.vidiq.com

The useful distinction is that this isn't merely “what keywords should I target?” — it can surface what your channel is already getting found for.

3. TubeBuddy — stronger for keyword/rank analysis
TubeBuddy's Keyword Explorer gives search volume, competition, related terms, and ranking-oriented analysis. www.tubebuddy.com

One important caveat

There isn't really a third-party tool that can perfectly tell you “these are all the keywords YouTube currently considers your video relevant for in Search + Suggested.”

That's because Suggested isn't fundamentally keyword-driven. YouTube reports the specific videos that generated Suggested traffic, rather than a list of “suggested keywords.” support.google.com

So if your goal is finding hidden content opportunities from videos that are already performing, I'd use:

YouTube Studio → actual search terms + suggested source videos → vidIQ for keyword expansion/ranking data

That combination can reveal things like: “My video is titled X, but YouTube is quietly sending it traffic for Y, Z, and this oddly specific phrase.” Those are often much more interesting opportunities than generic keyword-volume tools.

If you tell me whether you're talking about YouTube specifically (and roughly how many videos you have), I can point you to the tool/workflow that gets closest to automatically surfacing those “hidden ranking keywords.”

Yes — but there’s an important distinction between keyword research tools and tools that reveal what your existing videos are actually getting discovered for.

Best options

1. YouTube Studio — best source of truth
For each video, go to Analytics → Reach. YouTube directly shows:

• YouTube Search terms — the actual searches that led viewers to your video.
• Content suggesting this video — the specific videos that sent you traffic through Suggested. support.google.com

This is the closest thing to what you're describing, because it's based on your actual recent traffic, rather than estimated keyword volume.

2. vidIQ — better for finding the “niche within the niche”
vidIQ has keyword research with related/matching terms, questions, search volume, competition, and trend information. It also lets you track keywords and see which of your videos rank for them. support.vidiq.com

3. TubeBuddy — useful for ranking/keyword analysis
TubeBuddy Keyword Explorer provides keyword competition/search-traffic analysis, and TubeBuddy's current Recommended Tags feature incorporates information about searches driving views to your video. www.tubebuddy.com

For what you're specifically asking

If your goal is:

“Take my last 20 videos and tell me the weird/niche searches they're already ranking for + the videos they're appearing beside in Suggested, then find patterns I can make more videos around.”

I'd use YouTube Studio data as the raw data, then an analysis layer on top of it. YouTube itself also has a Trends tab that surfaces searches, breakout videos, recent videos, and content gaps based partly on your audience's behavior. support.google.com

That approach is actually more interesting than generic “YouTube keyword research,” because you can uncover unexpected keywords you never intentionally targeted.

If you tell me whether you're looking for a standalone tool or something that can automatically pull your channel's recent videos and surface those opportunities, I can point you to the closest options.

Yes. If you mean “show me the weird/niche queries that my existing videos are actually getting discovered through, plus what videos are feeding me Suggested traffic”, there are a few options.

Best starting point: YouTube Studio

YouTube itself gives you the underlying data:

• YouTube Search: for each video, go to Analytics → Reach → YouTube Search terms. This shows the actual terms viewers searched when they found your video. support.google.com
• Suggested Videos: the same Reach report shows the specific videos that are sending you Suggested traffic. support.google.com
• Advanced Mode: lets you dig into and export more granular analytics. support.google.com

The limitation is that Studio doesn't really turn this into a “here are the emerging niche keywords you're unexpectedly ranking for” discovery workflow.

Tools that make this more useful

vidIQ is probably the closest fit if your goal is keyword discovery. Its keyword tools provide search volume, competition, related terms, matching terms, questions, and trend information. support.vidiq.com

But there's an important distinction:

Keyword research tools tell you what people search for. YouTube Studio tells you what people actually searched to find your videos.

For the specific use case you're describing, I'd prioritize your actual Studio Search Terms + Suggested Videos data, then use vidIQ (or another research tool) to expand the promising niches.

The workflow I'd use

For every recent video, make a table like:

The 🔥 opportunities are especially interesting when a query is:

1. highly specific,
2. already producing impressions/views for you,
3. not the obvious topic you optimized the video around, and
4. connected to a cluster of Suggested videos.

That's often much more actionable than generic “high-volume keywords.” YouTube says Search ranking considers relevance to the search as well as engagement, while Suggested is personalized around what viewers are likely to watch next. support.google.com

If you want, I can also recommend a tool that specifically does the “upload/connect my channel → find hidden keywords my existing videos are ranking for → identify Suggested-video clusters” workflow, including free vs. paid options.

Yes — but there’s an important distinction between tools that estimate keywords and tools that show what your videos are actually getting discovered for.

Best source: YouTube Studio itself

For your own videos, YouTube Studio is actually the most useful starting point. In each video's Analytics → Reach, YouTube exposes:

• YouTube Search terms — the actual queries viewers used to find your video.
• Suggested videos — the specific videos that sent viewers to yours through recommendations.
• Other discovery sources such as Browse/Home and playlists. support.google.com

The catch: YouTube can suppress very-low-volume search queries, so you won't necessarily see every obscure/niche query that generated a view. support.google.com

If you want a tool that goes further

TubeBuddy is probably closest to what you're describing. Its Rank Tracker can monitor where your videos rank for keywords, while Keyword Explorer finds related/long-tail opportunities. www.tubebuddy.com

vidIQ is another strong option for discovering niche/related keywords. Its current Keyword Research tool has matching terms, related keywords, questions, and trending-video research. support.vidiq.com

But neither is literally a magic "show me every obscure keyword YouTube is currently associating with my recent videos" dashboard. For that, I'd combine your actual Studio data with keyword/rank-tracking data.

There's also a newer YouTube-native feature

As of 2026, YouTube Studio's Trends tab is particularly interesting. It can show Top searches, breakout videos, recent videos, and content gaps, based partly on what your audience has watched/searched over the previous 28 days. support.google.com

If what you're really after is:

"I uploaded a video 3 days ago. What weird/niche searches is YouTube already surfacing it for, and what videos is it being suggested next to?"

I can show you a specific workflow to extract those signals from YouTube Studio and turn them into a list of new video topics/keywords.
