AI Search Visibility Checker

Find out if AI search recommends you — or your competitor.

An AI search visibility checker tells you whether ChatGPT, Perplexity, Gemini and Claude actually **name your brand** — or **cite your site** — when buyers ask about your category, and which sources each engine pulled to get there. Your Google ranking doesn't predict this, so you have to check it directly. SourceWatch's free, working check is the AI SEO audit: enter one URL and in about 15 seconds see whether AI engines can read, recognize and recommend that page — plus your top fixes if they can't. No login to see your score. A trial turns that one-page check into ongoing, cross-engine visibility tracking.

TL;DR

  • **An AI search visibility checker** answers one question: when someone asks AI about your category, does it **mention your brand** or **cite your site** — or name a competitor instead? It measures four things: mention rate, share of voice vs competitors, the real questions being asked, and what the AI actually cited.
  • **A mention is not a citation.** A mention means the AI named you; a citation means it pulled a specific source to say it. Citations are the stronger signal — and the only one that sends a referral click.
  • **SourceWatch's free check is the AI SEO audit** — one URL, a 0–100 AI-readiness score, a Google-recognition verdict, an AI-crawler access check and your top fixes. Point-in-time, one page, no card. Full-site tracking across all four engines is on the trial.
  • **Moat 1 — first-party traffic, verified.** SourceWatch also captures the real AI crawlers and AI-referral clicks on your own site, checked against vendor IP ranges — measured, not inferred from synthetic prompts.
  • **Moat 2 — works inside Claude Code.** SourceWatch ships an MCP server, so your assistant can read the data and act on it in-loop. Almost no AI visibility tool does this. (REST API coming soon; MCP is the programmatic surface today.)

What an AI search visibility check actually measures

"Are we visible in AI?" is too vague to act on. A real AI search visibility check breaks it into measurable pieces — per engine, because ChatGPT, Perplexity, Gemini and Claude each source their answers from different places. Being visible in one is not being visible in all. Four signals decide whether AI puts you in the answer:

  • **Mention rate** — across the real questions buyers ask, how often does each engine name your brand at all? This is your baseline presence, and usually the first number that surprises people.
  • **Share of voice vs competitors** — when the AI does answer, who gets named: you, or the competitors it lists instead? Share of voice turns "we're invisible" into "we win 2 of 10 prompts and a rival wins 6."
  • **The real questions being asked** — visibility is per-question. The actual prompts in your category show exactly which questions you win, which you lose, and which you've never shown up for.
  • **What the AI actually cited** — the signal that matters most: the specific sources the model pulled to build its answer — your own pages, a directory, a competitor's blog, a Reddit thread. You can't earn a citation you can't see.

A mention is not a citation

Plenty of tools tell you your name appeared. The useful question is what source the model trusted to say it — because that's where the work to improve actually lives. A citation is the stronger authority signal and the only one of the two that drives a real referral click. SourceWatch reads both.

Why checking AI search visibility matters now

Search used to end in a click. Increasingly it ends in an answer — and the answer names a few brands and moves on. The shift isn't hypothetical; it's measured. ChatGPT alone reached roughly 900 million weekly active users in early 2026, and when an AI summary is present the clicks that used to flow to websites are staying inside the answer.

8% vs 15%

Google traditional-link click rate when an AI summary appears vs when it doesn't — clicks inside the summary happen only ~1% of the time (Pew Research, 2025)

In Pew Research's 2025 study of 900 U.S. adults across nearly 69,000 searches, users clicked a traditional result in just 8% of visits when a Google AI summary was shown, versus 15% with no summary — roughly half. Clicks on links inside the summary happened in only about 1% of visits. So the question stops being "where do I rank?" and becomes "am I one of the few brands the AI names — and what did it cite to choose them?" If you're not in the answer, you're not in the consideration set.

The good news: AI visibility is optimizable

This isn't a lottery. The peer-reviewed GEO paper (Aggarwal et al., KDD 2024) showed that the right content tactics — answer-first structure, citable statistics, quotations and clear sourcing — can lift a page's visibility in generative-engine responses by up to 40%. A checker tells you where you stand; the fixes tell you how to climb. See how it works.

What SourceWatch surfaces — and the two things rivals structurally can't

The free audit reads a single page the way AI engines do. A SourceWatch trial turns that into ongoing, cross-engine intelligence — plus two things almost no competitor has, because both require being on your own analytics, not just prompting the models.

Moat 1 — Real AI traffic, verified, not just synthetic prompts

Most checkers infer your visibility by firing test prompts at the models and seeing if your name comes back. SourceWatch does that and captures the real thing: actual AI-crawler hits and AI-referral clicks on your own site, verified against each vendor's published IP ranges so a spoofed user-agent pretending to be GPTBot doesn't pollute your numbers. So you see not just "the model said your name in a test," but who actually arrived from ChatGPT, Perplexity, Gemini and Claude — first-party data a prompt-sampling tool can't reach.

Why "verified vs inferred" is the whole game on accuracy

Synthetic sampling can be badly off. One review caught a prompt-sampling tool undercounting a brand's ChatGPT mentions by roughly 97%. First-party capture isn't a sample — it's the actual event, so it doesn't drift with which prompts you happened to pick.

Moat 2 — Act on it inside Claude Code (MCP-native)

SourceWatch ships an MCP server for Claude Code, so your visibility data is readable and actionable right inside the agent you already work in — pull the gaps, generate target prompts, draft fixes, all in the loop. Among self-serve tools this is effectively unique; the only comparable agent stack is enterprise-only and gated behind a separate subscription. (A documented REST API is coming soon; today the programmatic surface is MCP.)

On top of the two moats, a trial tracks the competitive core: mention rate, self-citation rate and share of voice vs named competitors; the actual search queries the models ran; most-cited domains and your citation gaps; daily tracking with drop and competitor-movement alerts; and content briefs aimed at the questions you're losing — across ChatGPT, Perplexity, Gemini and Claude.

Why you have to check every engine, not just one

Checking one engine is not checking all of them. Engines source their answers from wildly different places, so the same brand can dominate one and be invisible on another. A Profound analysis of 680 million citations makes the divergence concrete: ChatGPT leaned heavily on Wikipedia (47.9% of its top-10 sources) while Perplexity leaned on Reddit (46.7%), and Google AI Overviews was more balanced. If your brand has a strong encyclopedic presence but no community footprint, you may post a healthy ChatGPT visibility and near-zero Perplexity visibility from the same questions.

EngineWhere it pulls answers from (top source signal)What that means for your visibility
ChatGPTWikipedia-heavy (47.9% of top sources)Encyclopedic authority and a clean entity wins
PerplexityReddit-heavy (46.7% of top sources)Community footprint and discussion wins
Google AI OverviewsBalanced (Reddit 21.0%, YouTube 18.8%)Mixed signals; classic fundamentals still carry
Gemini & ClaudeDistinct source mixes againPer-engine reads — never assume one stands in for the rest

So a real check tracks the major engines separately and reports a per-engine read, not a blended headline that hides where you're losing. The per-engine split is what tells you which source to earn next — a Wikipedia entry, a stronger community presence, fresher pages, or schema-marked content. SourceWatch runs your category's real questions against each engine and layers in the first-party traffic actually hitting your pages.

Checked it and you're invisible? How to improve

A low score isn't a verdict — it's a to-do list. There's a lot of GEO superstition online, so SourceWatch's recommendations lean on the peer-reviewed foundational GEO study (Aggarwal et al., KDD 2024) rather than folklore. The fixes that move AI visibility most are concrete and mostly within your control:

  • **Let the crawlers in.** Confirm GPTBot, ClaudeBot, PerplexityBot and Google-Extended aren't blocked in robots.txt. If they can't read you, you can't be cited — full stop. See AI crawlers.
  • **Become a recognized entity.** Add Organization schema and consistent references so Google's Knowledge Graph knows you're a real business. If Google doesn't recognize you, AI engines have nothing solid to cite.
  • **Write answer-first, with citable facts.** Lead each key page with a direct one-sentence answer, add a statistic, quote a source, and structure it for extraction. Adding statistics, quotations and citations is exactly what the GEO research found lifts generative-engine visibility most.
  • **Publish an llms.txt file.** The proposed open standard (Answer.AI, Sept 2024) maps your best content for LLMs. Treat it as forward-looking hygiene, not a guaranteed lever — it isn't yet confirmed to be read by ChatGPT or Gemini for live answers — but it's cheap and directionally right.

Free check vs full tracking — the honest contrast

The free audit and a SourceWatch trial do different jobs, and we'd rather be clear than overclaim. The free check reads one page point-in-time; the trial tracks your whole category across all four engines, daily — including the two moats. Here's the honest split:

Free AI visibility checkSourceWatch trial (14-day, card optional)
ScopeOne page (the URL you enter)Every page on your site
EnginesReads your page the way AI engines doChatGPT, Perplexity, Gemini & Claude, daily
Mention rateTracked over time, per engine
Share of voice vs competitorsYes — vs the competitors AI names instead
Real questions in your categoryYes — by topic and intent
What the AI citedSnapshot of one pageMost-cited domains + your citation gaps
Real AI traffic (crawlers + referrals)Yes — first-party, IP-verified (moat)
Claude Code MCP serverYes — act on the data in-loop (moat)
AlertsYes — visibility drops + competitor moves
ResultOn-screen in ~15s, no loginOngoing dashboard + briefs to fix gaps

What SourceWatch does NOT do (so you choose with eyes open)

It doesn't generate content for you — it tells you exactly what to write and where the gaps are. There's no public REST API yet (MCP today, REST coming soon). The free audit covers one page; full-site is the trial. And no honest tool can promise a Google Knowledge Panel or guaranteed ROI — anyone who does is selling you a coin flip.

Start with the free single-page check, then track your whole category across ChatGPT, Perplexity, Gemini & Claude on a free trial.

Frequently asked questions

What is an AI search visibility checker?

A tool that shows whether AI assistants — ChatGPT, Perplexity, Gemini and Claude — mention and recommend your brand when people ask about your category, and which sources those engines cite. SourceWatch measures four things: how often you're mentioned (mention rate), how you stack up against named competitors (share of voice), the real questions being asked, and what the AI actually cited. Your Google ranking doesn't predict any of these, so AI search visibility has to be checked directly.

How do you check visibility across ChatGPT, Perplexity, Gemini and Claude?

SourceWatch runs the real questions in your category against each engine and records whether — and how — your brand shows up, then layers in first-party data from your own site: real AI-crawler hits and AI-referral clicks, verified against each vendor's published IP ranges. Checking every engine matters because each one pulls from different sources — across 680 million citations, ChatGPT leaned Wikipedia (47.9% of top sources) while Perplexity leaned Reddit (46.7%) — so being visible in one doesn't mean you're visible in all.

Is the AI visibility check free?

Yes — every business gets one free single-page check at /ai-seo-audit, no credit card and no login to see your result. You enter one URL and in about 15 seconds get a 0–100 AI-readiness score, a Google-recognition verdict, an AI-crawler access check and your top fixes. To track your whole site across all four engines daily — with mention rate, share of voice and what each engine cited — start a 14-day free trial (card optional).

What's the difference between a mention and a citation, and why does it matter?

A mention means your name appeared in the AI's answer — good for awareness, but it doesn't necessarily send anyone to your site. A citation means the AI linked to your domain as a source it trusted to build the answer. Citations are the stronger authority signal and the only one of the two that drives an actual referral click — and they're where the work to improve lives. SourceWatch shows you both, plus the exact sources (yours, a directory, or a competitor's) the model pulled.

Can you guarantee I'll get cited or rank in AI answers?

No, and you should distrust anyone who does. AI answers are non-deterministic — the same prompt can return different brands on different days — any check is a sample, and there's no paid placement in organic AI answers. What we can do: show you exactly where you stand today, track it over time, and give you research-backed fixes. The peer-reviewed GEO study (Aggarwal et al., KDD 2024) found adding statistics, quotations and citations can lift a page's visibility in AI answers by up to 40%.

How is this different from a normal SEO tool or rank tracker?

A rank tracker grades you for Google's blue links. An AI search visibility checker grades you for AI answers — a different signal with different fixes, and the two don't reliably correlate. SourceWatch also captures real AI traffic (who actually arrived from ChatGPT, Perplexity, Gemini and Claude, verified against vendor IP ranges) and is MCP-native, so you can act on the data inside Claude Code — things classic SEO suites don't do.

Does llms.txt help my AI visibility?

It's a sensible, low-cost step — a root Markdown file that maps your best content for LLMs, proposed by Answer.AI in September 2024 — but it's an emerging standard, not yet confirmed to be read by ChatGPT or Gemini for live answers. SourceWatch flags it as forward-looking hygiene, not a guaranteed ranking lever. We recommend it because it's cheap and directionally right, and we'll tell you plainly that it's not a magic switch.

Source: The /llms.txt standard proposal
Can I check my AI visibility for free, by hand?

Yes. Build a query bank of 30–50 real customer questions, run about 10 a week across ChatGPT, Gemini and Perplexity, and for each answer log whether you were mentioned, whether you were cited, roughly your position, and which competitors were named instead. After a few weeks you'll see your mention rate, average position and the topics you're absent in. It's real work — exactly the loop SourceWatch automates across all four engines on a schedule, alongside the first-party AI traffic a manual check can't see.
