ChatGPT answers, unedited

Yes — there are a few free ones now, and for a freelancer doing client SEO reports, I’d look at these:

• semrush.com — Probably the best starting point. You can enter a domain/URL and get an AI visibility score, mentions, platforms, cited pages, topics/prompts, and estimated audience reach. It checks ChatGPT, Gemini, Google AI Mode and AI Overviews. Semrush
• rankbits.com — Particularly relevant to what you're asking: enter a website and it gives share of voice among brands/competitors, mentions vs. citations, and a competitive landscape. The free scan checks ChatGPT, Google Search and Google AI Overview. RankBits
• therankagent.com — Explicitly calculates AI share of voice by asking buyer-intent questions and comparing how often you vs. competitors get recommended. Free, no login for the snapshot. RankAgent
• ahrefs.com — Good for client reporting because it shows mentions across ChatGPT, Gemini, Perplexity, Copilot and Google AI Overviews, plus cited domains/pages. It's free with no signup, although the full competitive AI Share of Voice functionality is part of the paid product. Ahrefs
• frase.io — Nice if you specifically want to enter a domain or individual URL and see whether ChatGPT, Perplexity and Gemini cite it, along with share-of-voice/citation metrics. Frase

What I'd use for client SEO reports

If your goal is something like:

Client: Acme Plumbing
AI Share of Voice: 18%
Competitor A: 31%
Competitor B: 24%
Competitor C: 12%
Platforms: ChatGPT / Perplexity / Gemini
Top cited pages: ...

I'd try RankBits or RankAgent first because they're closer to an actual share-of-voice metric rather than just an "AI visibility score."

One caveat: AI SOV isn't yet a standardized metric. Different tools use different prompts, engines, weighting, and definitions of "mention" vs. "citation." So for client reports, I'd label it something like "AI Search Share of Voice (tool methodology)" rather than presenting the percentage as an absolute market statistic.

If you want, I can also find you the best genuinely free option that lets you enter a URL + competitors and export a client-friendly report/PDF.

Yes. If you’re doing SEO reports for clients, there are a few free tools that are actually useful for this now.

Best options

• rankbits.com — probably the closest match to what you described. Enter a website and it gives you AI share of voice, competitors, mentions/citations, and a visibility score. It checks ChatGPT, Google Search, and Google AI Overviews, with a free scan and no signup. RankBits
• asklantern.com — particularly interesting for client reporting because you enter the website URL and it reports visibility percentage, share of voice vs competitors, and platform-level results. No account required. Lantern
• semrush.com — accepts a domain/URL and gives an AI visibility score, mentions, cited pages, topics/prompts, and estimated audience. The free version is more of a snapshot. Semrush
• frase.io — lets you paste a domain or specific URL and measures share of voice, citations, momentum, and sentiment across AI answers. The free checker is limited, but useful for a quick client snapshot. Frase
• therankagent.com — explicitly designed around AI share of voice. You enter the customer's search category + website and it runs five buyer questions, showing your share versus competitors. Free/no login for the basic snapshot. RankAgent

What I'd use as a freelancer

For a client report, I'd start with RankBits or Lantern. They're closer to the workflow you're after:

Client URL → AI visibility/SOV → competitors → citations → screenshot/export into monthly SEO report.

One caveat: AI share of voice isn't yet as standardized as Google rankings. A tool might calculate SOV based on 5–20 prompts, while another uses a much larger prompt dataset, so I wouldn't present "AI SOV = 23%" as an industry-standard metric. I'd label it something like "AI Search Share of Voice (tool methodology)" and use the same tool and prompt set month-to-month.

If you want, I can also find you the best completely free option that lets you run multiple client URLs and export/share a branded report.

Yes. For a freelancer doing client SEO reports, there are a few actually-free options now:

1. Ahrefs Free AI Visibility Checker — probably my first choice. You enter a brand, and it checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. It gives mentions, citations, platforms, topics, etc. No signup. The catch: the free checker doesn't give the full competitive AI Share of Voice report—that's part of paid Brand Radar. ahrefs.comhelp.ahrefs.com

2. RankAgent AI Share of Voice Checker — closest to exactly what you're asking for. Enter the customer's website, their category/search query, and optionally location. It runs five buyer-style questions and gives you a percentage showing how often the brand is recommended versus competitors. Free, no login for the basic result. www.therankagent.com

3. Frase AI Visibility Checker — particularly interesting for an SEO report because you can enter an actual URL, not just a brand. It checks AI citations and reports visibility/share-of-voice-type metrics. www.frase.io

4. Semrush AI Search Visibility Checker — accepts a domain or URL and gives AI visibility, mentions, citations, prompts/topics and estimated audience reached. www.semrush.com

What I'd use for client reports

If you're trying to produce a nice "AI SEO / GEO snapshot" without paying for another subscription, I'd use:

RankAgent → AI Share of Voice %
Ahrefs → AI mentions + citations + platforms
Frase → URL-level citation visibility

Then put something like:

AI Search Visibility: 12%
AI Share of Voice: 8.4%
AI Platforms Detected: ChatGPT, Gemini, Perplexity
Top Competitor: Competitor.com — 21.7%
Pages Currently Cited: /service-page, /blog/article

One important distinction: "AI visibility," "AI mentions," "AI citations," and "AI share of voice" aren't interchangeable. Ahrefs, for example, defines AI SoV as your share of impressions relative to tracked competitors, whereas some free tools calculate SoV simply from the proportion of AI answers that mention you. help.ahrefs.com

If you tell me what kind of SEO clients you have (local businesses, SaaS, ecommerce, etc.), I can also point you to the best free checker specifically for generating a client-facing AI SEO report rather than just an interesting score.

Yes — there are a few free ones now that are actually useful for SEO client reporting.

Best options

1. RankAgent AI Share of Voice — probably the closest match to what you're asking for.
   • Enter a website + target category/query
   • Runs 5 buyer-style AI questions
   • Shows your share of recommendations vs. competitors
   • No signup for the basic snapshot. www.therankagent.com

2. Frase AI Visibility Checker — good if you want something more SEO-report oriented.
   • Accepts a domain or specific URL
   • Checks ChatGPT, Perplexity and Gemini
   • Reports share of voice, citations, momentum and sentiment
   • Free checker, though the ongoing tracking is paid. www.frase.io

3. Ahrefs AI Visibility Checker — nice for client-facing credibility.
   • Checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode
   • Free, no signup
   • Shows mentions and which pages/domains are being cited
   • The free version is more of a snapshot than a full SOV tracker. ahrefs.com

4. AnswerMonk — interesting specifically for agencies/freelancers.
   • Give it a URL and it generates buyer prompts
   • Tests ChatGPT, Gemini and Claude
   • Gives AI share of voice + competitor rankings + citation sources
   • Free audit, with ongoing monitoring paid. www.answermonk.ai

If you're making SEO reports for clients

I'd probably use RankAgent for the actual "AI SOV %" number, then pair it with Ahrefs or Frase for citation/visibility evidence.

One important distinction: tools like IsVisible.ai give you an AI crawler/accessibility score—whether GPTBot, ClaudeBot, etc. can access the site—not AI search share of voice. isvisible.ai

If you tell me what kind of SEO clients you have (local businesses, SaaS, ecommerce, etc.), I can also find you the best genuinely-free tool that lets you generate a branded/client-ready AI SOV report, ideally without making you sign up for a trial.

Yes — there are a few free AI visibility / AI Share of Voice checkers that are pretty useful for client SEO reports.

Best free options

1. Ahrefs Free AI Visibility Checker — probably my first choice. Enter a brand/domain and it checks visibility across ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews. It gives mentions, platforms, topics, cited domains/pages, and a limited free report. ahrefs.comhelp.ahrefs.com

Best for: a quick client-facing snapshot.

2. Semrush AI Search Visibility Checker — free, no signup, and accepts a domain/URL. It checks AI visibility and competitive positioning across ChatGPT, Gemini and Google AI Overviews. www.semrush.com

Best for: adding a recognizable SEO-tool name to your reports.

3. AI Share of Voice — more directly aligned with what you're asking for. You enter your domain + competitors + keywords and get AI citation share across a keyword set. aishareofvoice.io

Best for: an actual “Client has 14% AI Share of Voice vs. Competitor A at 31%” type metric.

4. Frase AI Visibility Checker — accepts a domain or specific URL, and reports share of voice, citations, momentum, and sentiment from AI responses. The free checker includes a ChatGPT result; more comprehensive tracking is paid. www.frase.io

Best for: when you specifically want to evaluate an individual client's page/URL, rather than just the brand.

5. Lantern Free AI Visibility Report — enter a website URL and get visibility scores and share of voice versus competitors across AI platforms. www.asklantern.com

For a freelancer doing client reports

I'd probably use Ahrefs + AI Share of Voice:

• Ahrefs: “Your brand was mentioned X times across AI search”
• AI Share of Voice: “Your domain owns X% of AI citations for these target queries”
• Then manually grab 3–5 important prompts and show exactly what ChatGPT/Perplexity/Google AI says and which competitors get cited.

One important distinction: AI visibility ≠ AI Share of Voice. A tool can tell you “your site appeared in 30% of answers,” but true SoV needs a defined prompt/keyword universe and comparison against competitors. Ahrefs itself describes AI SoV as a competitive benchmark, while its free checker is more of a visibility snapshot. help.ahrefs.com

If you tell me what kind of clients you report for (local businesses, SaaS, ecommerce, law firms, etc.), I can point you to the best free setup for generating a polished AI SOV section in your SEO reports.

Yes — there are a few, and some actually give you AI Share of Voice rather than just an “AI-readiness” score.

Best free options for client SEO reports

1. Lantern AI Visibility Report — probably the closest match to what you're asking for. Enter a website URL and it reports AI visibility + Share of Voice, including how often the brand is recommended versus competitors across ChatGPT, Perplexity and Gemini. No account required for the initial report. www.asklantern.comahrefs.com

2. Frase AI Visibility Checker — particularly useful for SEO work because it can analyze AI answers, share of voice, citations, competitors and sentiment. The free checker is limited, but it's more actionable than a simple GEO score. www.frase.io

3. CitedSpy AI Visibility Checker — free/no signup and specifically gives a 0–100 visibility score, competitor Share of Voice, prompt-level rankings and cited sources. It checks ChatGPT, Perplexity, Gemini, Claude and Grok. www.citedspy.com

4. Ahrefs Free AI Visibility Checker — very credible option for client reporting. It checks ChatGPT, Gemini, Perplexity, Copilot and Google AI surfaces and gives mentions, topics and cited domains. Caveat: the free checker is more of a snapshot; historical/true competitive SOV tracking is part of their paid Brand Radar product. ahrefs.com

5. Discoverable AI Visibility Checker — free snapshot with visibility score, competitors ahead of you and citation gap. It actually runs buyer-style prompts against AI engines rather than merely checking your site's technical AI accessibility. bediscoverable.ai

One important distinction

A lot of “AI visibility checkers” aren't really measuring Share of Voice.

For example, IsVisible.ai gives a free URL-based AI crawler accessibility score — robots.txt, llms.txt, GPTBot, ClaudeBot, PerplexityBot, etc. That's useful for a technical SEO audit, but it doesn't tell you “you have 18% of the AI answers in your market.” isvisible.ai

For your use case as a freelancer, I'd start with Lantern + CitedSpy. They give you numbers that make much more sense in a client report:

AI Share of Voice: 14%
Visibility: 31/100
Top competitor: Competitor X — 42%
Engines monitored: ChatGPT, Gemini, Perplexity, Claude
Citation gap: 7 relevant sources cite competitors but not you

That is considerably more compelling to a client than “your llms.txt is missing.”

If you tell me what kind of SEO clients you have (local businesses, SaaS, ecommerce, agencies, etc.), I can also find you the best genuinely-free tool that lets you put the AI SOV number into a recurring white-label client report.

Yes. For client SEO reports, there are a few free (or freemium) tools that can give you an AI Share of Voice / AI Visibility metric. The catch: most measure brand visibility in AI answers, not a URL’s organic “AI ranking” in the same way Ahrefs/SEMrush measure Google rankings.

Good options:

For a freelancer doing recurring SEO reports, I’d probably use this workflow:

1. Traditional SEO section
   • Google Search Console data
   • GA4 traffic
   • Ahrefs/Semrush/Ubersuggest keyword movement

2. AI visibility add-on
   • Run the client domain through Ahrefs or Semrush
   • Track:
     • AI visibility score
     • % of prompts where brand appears
     • competitors appearing instead
     • cited URLs/pages

3. Create your own AI Share of Voice metric

Example:

   AI Share of Voice = Client mentions ÷ (Client mentions + Competitor mentions) × 100

So if ChatGPT/Gemini/Perplexity responses mention:

• Client: 18 times
• Competitors: 82 times

AI SOV = 18%

One thing to watch: many tools say “URL checker,” but the underlying metric is usually brand/entity visibility, not “this exact page is winning AI answers.” For local SEO clients, the domain-level reports are usually more useful because AI engines often pull from reviews, directories, and third-party mentions too. www.citedspy.com

If you’re packaging reports for clients, I’d lean toward Ahrefs free checker + a simple custom AI SOV table because it looks the most familiar to SEO buyers. ahrefs.com

Yep — there are a few actually free options now that are useful for client SEO reports.

Best options

1. Lantern AI Visibility Report — probably the closest match to what you're asking for. You enter a website URL and it reports AI visibility plus share of voice vs. competitors across ChatGPT, Perplexity, and Gemini. No account required. www.asklantern.com

2. Frase AI Visibility Checker — accepts a domain or individual URL and analyzes AI mentions, citations, share of voice, momentum, and sentiment. The free checker gives you a useful snapshot. www.frase.io

3. CitedSpy AI Visibility Checker — free/no signup and checks ChatGPT, Perplexity, Gemini, Claude, and Grok. It gives a visibility score, competitor share-of-voice breakdown, rankings, and cited sources. www.citedspy.com

4. Ahrefs Free AI Visibility Checker — excellent if you're already using Ahrefs. It checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. The catch: the free tool gives a snapshot; AI Share of Voice and historical/competitive tracking are part of the paid Brand Radar product. ahrefs.com

For your use case

If you're a freelancer and want something you can drop into a client report, I'd start with Lantern or CitedSpy.

One important distinction: AI "share of voice" isn't really a property of a URL in the same way traditional SEO metrics are. These tools generally use the URL/domain to identify the brand, generate relevant commercial prompts, query AI engines, and calculate something like:

Your brand mentions ÷ total competitor/brand mentions

So I'd report it to clients as "AI Search Share of Voice" rather than implying that the percentage is an objective ranking metric.

If you want, I can also find you the best completely free tool that lets you enter a client's URL + 3–5 competitors and produces a client-presentable AI SOV report/PDF.

Yes — but the market is still pretty immature. There are a few free (or freemium) tools you can use for client SEO/GEO reports. The key distinction: some measure AI visibility/share of voice, while others only audit whether a URL is “AI-friendly.”

Here are the better options:

rankseer.com

For a freelancer making client SEO reports, I’d probably do this workflow:

1. Run the client URL through a free AI visibility/GEO audit:
   • AI citations found
   • AI readability issues
   • schema/content gaps
   • competitor mentions

2. Create your own “AI Share of Voice” metric:
   • Pick 20–50 buyer-intent prompts:
     • “best [service] in [city]”
     • “top [product category] providers”
     • “how to choose [service]”
   • Run them through ChatGPT/Perplexity/Gemini manually or with a tracker.
   • Count:
     • % of prompts where client appears
     • average position in answers
     • citations received

3. Report it alongside traditional SEO:
   • Organic rankings
   • Traffic
   • Backlinks
   • AI visibility %

A lot of agencies are calling this GEO (Generative Engine Optimization) or AI SEO now, so adding a one-page AI visibility section to your existing SEO reports can be a nice differentiator. www.rankseer.com

If you want something that looks client-ready with a PDF export/white-label feel, the free tools are more limited — you may need a paid platform or a custom spreadsheet/dashboard approach.

Yes — there are a few now, but “AI Share of Voice” and “AI visibility” aren’t quite the same thing.

For your use case as a freelancer producing client SEO reports, I’d look at these:

1. Ahrefs Free AI Visibility Checker — probably the best quick client-facing option. You enter a brand, and it checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. It gives mentions, topics, cited domains/pages, etc. No signup. ahrefs.com
   • Catch: the free checker doesn't give the actual competitive AI SoV percentage; that's part of Ahrefs Brand Radar.

2. CitedSpy AI Visibility Checker — this is closer to what you're asking for. It accepts a brand + optional domain, finds competitors, checks 5 AI engines, and explicitly reports competitor share of voice, rankings, sentiment, and cited sources. It says the full check is free with no signup. www.citedspy.com

I'd try this first for your reports.

3. Frase AI Visibility Checker — particularly useful because you can enter a domain or specific URL. It checks whether AI engines cite the site/page. The free version is more of an AI visibility/citation check than a true competitive SoV report. www.frase.iowww.semrush.com

4. Semrush Free AI Search Visibility Checker — accepts a domain or website URL and reports visibility/competitive positioning across AI search. www.semrush.com

If you're building reports for clients

I'd distinguish the metrics like this:

AI Share of Voice:

“Of all brand mentions in AI answers for this client's target topics, X% belong to the client.”

AI Visibility:

“How frequently does AI mention/cite this brand?”

Citation Share:

“How often does AI cite this client's domain/pages versus competitors?”

For an SEO report, AI SoV + competitor names + cited URLs is much more compelling than a generic “AI visibility score.”

One particularly interesting option is CitedSpy, because its free checker actually gives you a competitor SoV breakdown rather than just an arbitrary 0–100 score. www.citedspy.com

If you tell me what your client report currently looks like (e.g. Looker Studio/PDF/Google Docs), I can also find you a free workflow where you enter a client's URL and automatically produce an AI SoV number + competitors + citations without paying for Ahrefs/Semrush.

Yes. If you're doing client SEO reports, there are a few free options worth knowing about:

Best free options

1. Semrush AI Search Visibility Checker — probably the best fit for your use case. You can enter a domain/URL and it reports AI visibility across ChatGPT, Gemini, and Google AI Overviews, including an overall visibility score and competitor positioning. No signup is required for the checker. www.semrush.com

Semrush AI Search Visibility Checker

2. Ahrefs Free AI Visibility Checker — very good for quick client snapshots. It checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode, and shows mentions, platforms, topics, cited domains, and cited pages. It accepts a brand/product name rather than directly analyzing an arbitrary URL. ahrefs.com

Ahrefs Free AI Visibility Checker

But if you specifically mean "AI Share of Voice %"

That's a slightly different metric. You want something like:

Client: 18% AI SOV
Competitor A: 31%
Competitor B: 24%
Competitor C: 12%

Semrush's paid AI tooling explicitly has AI Share of Voice, while its free checker is more of a visibility snapshot. Ahrefs likewise says its free checker gives a snapshot, while AI Share of Voice and competitive benchmarking are part of the paid Brand Radar product. ahrefs.com

For a freelancer, I'd use Semrush's free checker for the report and label the metric "AI Search Visibility" rather than "AI Share of Voice." That avoids implying you're calculating a true market share percentage when you're really measuring presence.

If you want, I can also find you 3–5 genuinely free tools that give an actual AI SOV percentage and let you enter a client URL + competitors, rather than the usual "free" tools that turn out to require a paid subscription.

Yes. If you're doing SEO reports for clients, there are a few free options now, but there's an important distinction between AI visibility and actual AI Share of Voice (SoV).

Best free options

1. Semrush AI Search Visibility Checker — probably the easiest for client reports

Semrush AI Search Visibility Checker

• Enter a domain/URL
• Checks visibility across AI search platforms including ChatGPT, Gemini and Google AI Overviews
• Shows how you compare with competitors
• No signup required according to Semrush www.semrush.com
• Best fit if you want something you can quickly screenshot/export into a report.

2. Ahrefs Free AI Visibility Checker — excellent quick snapshot

Ahrefs Free AI Visibility Checker

• Free, no signup
• Checks ChatGPT, Gemini, Perplexity, Copilot and Google AI Overviews
• Shows mentions, topics and cited domains/pages
• But: the free checker gives a limited snapshot; actual AI Share of Voice and competitor benchmarking are part of Ahrefs Brand Radar. ahrefs.comhelp.ahrefs.com

If you specifically need a percentage like "AI SoV = 12.4%"

That's harder to get completely free.

Semrush defines AI SoV roughly as:

your AI mentions ÷ total AI mentions across brands × 100

and its paid tooling calculates it using both mentions and position/prominence. www.semrush.com

Ahrefs likewise has AI Share of Voice as a dedicated metric in Brand Radar. ahrefs.comhelp.ahrefs.com

So if your client report has a section like:

—you generally need a proper tracking tool rather than a simple URL checker.

One other free option

There's also FreeSOV, which was specifically built around AI prompt tracking and SoV. It can track whether ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews mention/cite/rank you, although it requires bringing your own LLM/DataForSEO keys. www.reddit.com

For your freelancer use case, I'd start with Semrush + Ahrefs' free checkers. If you're trying to build a repeatable AI-visibility section into every client's monthly SEO report, I can also find you the cheapest/free tools that let you track 10–20 client domains and generate an actual AI SoV percentage.

Yes. If you’re producing SEO reports for clients, there are a few free options worth testing.

Best free options

1. Semrush AI Search Visibility Checker — probably the best fit for your use case. You can enter a domain/URL, and it checks visibility across AI platforms such as ChatGPT, Gemini, and Google AI Overviews, including competitive positioning. No signup is required. www.semrush.com

3. Ahrefs Free AI Visibility Checker — very polished and useful for client-facing reports. It checks ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews and shows mentions, topics, and cited domains/pages. The catch is that AI Share of Voice itself is part of the paid Brand Radar product, while the free checker gives a limited snapshot. ahrefs.com

urlAhrefs Free AI Visibility Checkerturn0search0

4. Discoverable — free snapshot with a domain, including an AI visibility score, competitors appearing ahead of you, and a citation gap. It tests multiple AI engines. bediscoverable.ai

urlDiscoverable AI Visibility Checkerturn0search6

For your specific need

If by "AI share of voice" you mean something like:

Client's domain = 18% of AI mentions/citations for 50 relevant prompts
Competitor A = 32%
Competitor B = 24%

then Frase is the closest match among the genuinely free tools I found. www.frase.io

There are also some newer free tools specifically aimed at this metric. CitedSpy, for example, claims to provide a 0–100 visibility score, competitor share-of-voice breakdown, prompt-level rankings, sentiment, and cited sources across ChatGPT, Perplexity, Gemini, Claude, and Grok. www.citedspy.com

One caveat for client reports: AI visibility/SOV isn't as stable as Google rankings. AI responses vary by prompt, location, model, and time, so I'd label the metric something like "AI Search Share of Voice (sampled prompts)" rather than presenting it as an absolute percentage. www.techradar.com

If you tell me what kind of SEO clients you have (local businesses, SaaS, ecommerce, etc.), I can also give you a free AI-SOV reporting workflow you can repeat for every client and turn into a nice report section.

Yes — there are a few free options now, but there’s an important distinction between AI visibility and true AI Share of Voice (SoV).

Best free options for client SEO reports

1. urlSemrush AI Search Visibility Checkerturn0search4 — probably the best starting point.
   • Enter a domain/URL
   • Checks visibility across ChatGPT, Gemini, Google AI Overviews, etc.

2. urlAhrefs Free AI Visibility Checkerturn0search0 — very easy for prospect/client reports.

   • Checks ChatGPT, Perplexity, Gemini, Claude and Grok
   • Finds competitors automatically
   • Reports competitor share of voice, prompt-level rankings, sentiment and cited sources
   • Free/no signup. www.citedspy.com

One caveat for SEO reporting

If by "AI share of voice for a URL" you mean:

"This client's website gets 18% of the AI citations/recommendations for these 50 commercial queries, versus 31% for Competitor A"

that's a much more meaningful metric than an AI-readiness score.

Tools like IsVisible, AuditZap, SiteTest, etc. can tell you whether a page is technically accessible/crawlable by AI systems, but that's not AI SoV. isvisible.ai

For your use case as a freelancer, I'd test CitedSpy and Semrush first. CitedSpy appears particularly useful if you want an actual competitor SoV number that you can put into a monthly SEO/AEO report.

If you tell me what you want the report to show (e.g. "AI SoV %, citations, competitors, prompts, ChatGPT/Perplexity/Gemini"), I can also find you the best genuinely-free workflow for producing this for multiple clients, including options that don't require paying $100+/month.

Yes. For a freelancer making SEO reports, there are a few free (or freemium) AI Share of Voice / AI Visibility checkers that can give you something client-friendly.

Best free options

1. urlAhrefs AI Visibility Checkerturn0search0
2. Best for: quick client screenshots/reports

5. Best if you want URL-level checks rather than only brand/domain checks.
6. Looks at whether AI engines cite your content. www.frase.io

5. urlCitedSpy AI Visibility Checkerturn0search5
6. More explicitly focused on share-of-voice style metrics: mentions, competitor comparisons, and prompt-level visibility. www.citedspy.com

For client SEO reports, I’d structure it like this:

AI Search Visibility Snapshot

• AI Share of Voice: X%
• Competitors appearing more often: A, B, C
• AI engines checked: ChatGPT / Gemini / Perplexity
• Number of tracked prompts
• Citation sources missing vs competitors
• Recommended actions:
  • improve entity signals
  • build authoritative mentions
  • update comparison/service pages
  • add clearer expertise signals

One caveat: AI Share of Voice is still an emerging metric. AI answers vary by prompt, location, personalization, and time, so a single score is best presented as a benchmark rather than a definitive ranking metric. arxiv.org

For a freelancer, I’d probably use Ahrefs or Semrush for the polished client-facing snapshot, then supplement with a manual prompt test spreadsheet for higher-value clients. www.semrush.comahrefs.com

Yes. If you mean AI Share of Voice (SoV) specifically—i.e. “for a set of relevant prompts, how often does this client’s brand/domain appear compared with competitors?”—there are a few free options worth testing.

Best free options

1. urlAhrefs Free AI Visibility Checkerturn0search0 — probably my first choice for client reports.
   • Free, no signup
   • Checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews/AI Mode
   • Gives mentions, topics, competitors/sources
   • Caveat: the free checker is more of a visibility snapshot; Ahrefs says actual ongoing AI Share of Voice + competitive benchmarking is in Brand Radar.

2. urlSemrush Free AI Search Visibility Checkerturn0search3 — particularly useful for an SEO freelancer because you can enter a domain/URL and get competitive AI-search visibility information. It checks things like ChatGPT, Gemini and Google AI Overviews.

3. urlDiscoverable AI Visibility Checkerturn0search2 — interesting for client reporting. Enter the domain and it generates buyer-style prompts, then shows a visibility score, competitors ahead of the brand, and a citation gap. The free snapshot doesn't require login.

4. urlFrase AI Visibility Checkerturn0search5 — accepts a domain or individual URL and specifically reports share of voice, citations, momentum and sentiment from AI responses. There's a free check, although ongoing monitoring is paid.

One important distinction

If you're making monthly SEO reports, I'd separate these into:

AI visibility / SoV

"Acme Plumbing appears in 18% of relevant AI answers vs. 31% for Competitor A."

vs.

AI crawlability/readiness

"Acme's site is accessible to GPTBot, ClaudeBot, PerplexityBot, etc."

For the latter, urlIsVisible.aiturn0search1 is a genuinely free URL checker, but it doesn't measure Share of Voice. It checks whether AI crawlers can access the site and gives an AI visibility/access score.

For your use case

If you're trying to produce a repeatable client-facing SEO report without paying $100+/month, I'd start with Ahrefs + Frase and see which produces the most useful numbers for your clients.

If you tell me what you want the report to show (e.g. AI SoV %, competitors, prompts, citations, ChatGPT vs Gemini vs Perplexity, monthly change), I can also find you the best genuinely free workflow, including a DIY spreadsheet/API approach if the existing tools aren't free enough.

Yes. There are a few genuinely free options that are useful for freelancers, although they measure slightly different things.

Here's how I'd rank them:

1. urlAhrefs AI Visibility Checkerturn0search1 ⭐ Best free overall
   • Free, no signup
   • Enter a brand or domain
   • Shows:
     • AI mentions
     • AI Share of Voice preview
     • Platforms (ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews)
     • Pages/domains cited
   • Limitation: full historical tracking requires their paid Brand Radar product. ahrefs.com

2. urlSemrush AI Search Visibility Checkerturn0search4
   • Free snapshot
   • Enter a URL/domain
   • Shows AI visibility and competitors
   • Good if clients already know Semrush. www.semrush.com

3. urlFrase AI Visibility Checkerturn0search2
   • Checks whether ChatGPT, Gemini, and Perplexity cite your domain
   • Gives visibility score and citations
   • Useful for quick audits. www.frase.io

4. urlIsVisible.aiturn0search0
   • Different purpose
   • Doesn't measure Share of Voice
   • Instead checks whether AI crawlers (GPTBot, ClaudeBot, Perplexity, etc.) can actually access the site via robots.txt/llms.txt.
   • Nice technical appendix for SEO reports. isvisible.ai

If you're building client SEO reports

A workflow that looks professional without paying for enterprise tools is:

That gives you an "AI Visibility" section alongside rankings, traffic, backlinks, and technical SEO.

If you're comfortable using APIs, you can also build your own AI Share of Voice report by running a set of client keywords through ChatGPT, Gemini, and Perplexity, then counting how often the client's domain is mentioned versus competitors. Many freelancers do this because it's inexpensive and can be customized to each niche, though results should be sampled over multiple runs since AI answers vary from one query to the next. arxiv.org

Yes. There are a handful of free tools that can give you a snapshot of AI share of voice (or AI visibility) for a URL/domain. Most are limited compared to paid platforms, but they're useful for freelancer client reports.

Here are the best free options:

For client reporting, I'd recommend this workflow:

1. Run the client's domain through Ahrefs AI Visibility Checker.
2. Verify with Frase to see actual AI citations.
3. Add:
   • Organic traffic (Google Search Console or Ahrefs/Semrush if available)
   • AI Visibility Score
   • AI Share of Voice
   • Top AI-cited competitors
   • Pages most likely to earn AI citations
   • Recommended GEO (Generative Engine Optimization) improvements

This creates a report that's more valuable than a standard SEO audit.

If you're making reports every month, the paid tools that agencies tend to use are:

• urlAhrefs Brand Radarturn0search0
• Semrush AI Toolkit
• Profound
• Peec AI

Those track trends over time instead of just providing a one-time snapshot.

If your clients are small businesses, the free Ahrefs + Frase combination is usually enough to add an "AI Visibility" section to your SEO reports without paying for another tool.

Yes. There are a few genuinely free options now that are useful for freelancers. The main difference is whether you want a one-time AI visibility snapshot or ongoing AI Share of Voice tracking.

My recommendations:

For client SEO reports, I'd usually use this stack:

• Ahrefs AI Visibility Checker – quick executive summary showing mentions across ChatGPT, Gemini, Copilot, Perplexity, and Google AI Overviews, plus cited pages. ahrefs.com
• Semrush AI Search Visibility Checker – good competitor comparison and AI visibility score. www.semrush.comahrefs.com
• Frase – useful if you want to demonstrate which pages AI is actually citing. www.frase.io

If you need a metric that's closest to a traditional Share of Voice chart, FreeSOV is probably the best free option because it measures visibility across multiple AI engines over your own prompt set. The tradeoff is that you need to supply your own API keys. freesov.com

A nice section to add to SEO reports is:

• AI Visibility Score
• AI Share of Voice (% vs competitors)
• Number of AI mentions
• Number of citations
• Top pages cited by AI
• Competitors appearing more often
• Recommended GEO/AEO improvements

Clients are increasingly asking for these metrics because they complement traditional rankings rather than replace them. www.semrush.comahrefs.com

If you're producing reports every month, I can also suggest a workflow that's almost entirely free using Google Sheets plus one of these checkers to create a repeatable AI visibility dashboard.

Yes. There are a few free (or free-tier) tools that estimate AI Share of Voice (AI SoV)—how often a URL or brand appears in responses from AI assistants like ChatGPT, Gemini, Claude, or Perplexity.

Here are the best options:

1. Peec AI
   • Free plan available.
   • Tracks how often your domain is cited across AI search prompts.
   • Lets you compare against competitors.
   • One of the better tools if you're producing client SEO reports.

2. Profound
   • Enterprise-focused.
   • May offer demos or limited trials.
   • Very comprehensive AI visibility tracking.

3. Otterly.AI
   • Free trial.
   • Tracks prompts across ChatGPT, Perplexity, and Google AI.
   • Good for recurring monitoring.

4. Scrunch AI
   • AI search analytics and visibility monitoring.
   • More geared toward agencies and larger brands.

5. Semrush AI Toolkit
   • Paid, but if you're already using Semrush it's worth exploring.
   • Includes AI visibility reporting alongside traditional SEO metrics.

If you want something completely free

There's no fully featured unlimited free AI SoV checker yet, but you can get close by:

• Using Google AI Mode or AI Overviews manually.
• Checking responses in ChatGPT, Gemini, Claude, and Perplexity for a fixed list of prompts.
• Recording whether your client's URL is mentioned or cited.
• Calculating:
  • AI Visibility % = prompts where the client appears ÷ total prompts.
  • AI Share of Voice % = client mentions ÷ total mentions across all competitors.

This approach works well for monthly SEO reports if you use the same prompt set every month.

For freelancers

If you're serving SMB clients, I'd recommend:

• Free: Peec AI's free tier + a manual prompt spreadsheet.
• Low-cost: Otterly.AI if you want automated monthly reports.
• Agency scale: Profound or Scrunch AI.

That combination gives you a credible "AI Visibility" section in client reports without needing an enterprise budget.

Yes. If you're creating SEO reports for clients, there are several free tools that measure AI visibility or AI Share of Voice (how often a brand or URL appears in AI-generated answers). They're not all the same, though.

Here's what I'd recommend:

Best free option: Ahrefs

The free checker:

• Tests ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews.
• Shows where your brand is mentioned.
• Breaks down mentions by AI platform.
• Shows which pages/domains are cited alongside your brand.
• Requires no signup for the basic report. ahrefs.com

If you want actual AI Share of Voice

The closest free option is:

• urlDiscoverable AI Visibility Checkerturn0search1

It reports:

• AI visibility score
• Competitors that appear ahead of you
• Citation gap
• Share-of-voice snapshot across several AI engines

The detailed report requires an email, but the initial snapshot is free. bediscoverable.ai

For agencies/freelancers

A workflow many freelancers use is:

1. Google Search Console (organic clicks/impressions)
2. Ahrefs or Semrush (SEO rankings/backlinks)
3. AI Visibility Checker (AI mentions/share of voice)
4. PageSpeed Insights
5. Screaming Frog (technical SEO)

That gives clients a report covering both traditional SEO and AI search visibility.

If you're building white-label monthly reports

There's no widely available free API that tracks AI Share of Voice across many prompts over time. Most ongoing tracking is paid (for example, Ahrefs Brand Radar, Semrush AI Visibility Toolkit, or similar platforms). For freelancers with a small client list, it's often practical to run one of the free checkers monthly and include the AI visibility score and competitor comparison in the report. ahrefs.com

If you're using tools like Looker Studio, Google Sheets, or Notion for your reports, I can also suggest a mostly free AI SEO reporting stack that looks polished and only takes a few minutes per client each month.
