AI Visibility Checker
Enter a domain and get a 0–100 AI-visibility score in seconds — crawler access, llms.txt, schema, metadata and answer-shaped copy, each with the exact fix.
Quick answer
This checker fetches public site resources and evaluates eleven documented technical checks, producing a 0–100 diagnostic score. The score is this tool's assessment, not a published ranking formula used by ChatGPT, Perplexity or Gemini, and it does not predict citations or traffic.
What AI visibility actually is
When someone asks ChatGPT or Perplexity for a recommendation, the engine assembles an answer from what it can read about you: whether its crawler is allowed in, whether your pages state plainly what you do, whether your entity is machine-verifiable, and whether a quotable answer sits near the top of the page. AI visibility is the sum of those signals — and almost all of them are technical, checkable, and fixable in an afternoon.
The eleven signals this checker audits
| Signal | Why answer engines weigh it | Weight |
|---|---|---|
| AI crawler access | A blocked GPTBot or PerplexityBot means zero citations from that engine, forever, no matter what else you fix. | 14% |
| Structured data (JSON-LD) | Organization and LocalBusiness markup give engines a verified entity to attach citations to. | 14% |
| llms.txt | The curated brief that tells models which pages to read first and how to describe you. | 12% |
| Title tag | The strongest single entity statement on a page — and what engines quote verbatim. | 10% |
| Answer-shaped copy | A 2–3 sentence plain-language opening with concrete numbers is the chunk engines lift. | 10% |
| Meta description | The fallback summary engines reuse when they paraphrase your link. | 8% |
| H1 heading | States what the page is in one machine-parsable line. | 8% |
| XML sitemap | Complete URL discovery for engines that crawl before they cite. | 8% |
| Open Graph tags | Reused when engines summarise or preview your link. | 6% |
How to track AI visibility over time
Re-run this checker after every meaningful change — it measures readiness, not results. For results, ask live models whether they name you with the AI Brand Mention Tracker, follow your answer position with the AI Rank Tracker, or run a ChatGPT-specific check with the ChatGPT Visibility Checker. Readiness first, mentions second — tracking a blocked site just measures the block.
What a good score looks like
- 90–100 (A): every major engine can read, verify and quote you. Keep files fresh as content changes.
- 75–89 (B): citable, but warnings are costing you ranking positions inside answers.
- 60–74 (C): engines can reach you but struggle to describe or trust you — schema and llms.txt usually missing.
- Below 60 (D/F): something is hard-blocked or missing. Fix the red checks first; nothing else moves the needle until you do.
From score to cited
The fixes this checker proposes are the same ones our full scanner ships as deploy-ready files: an AI-aware robots.txt, an llms.txt, and Organization JSON-LD. Generate, publish, and re-check — most sites move a full grade in one session.

Build around the decision your audience is making
Industry-specific GEO starts with a real question, not a generic page containing an industry keyword. A software buyer may need compatibility, security and pricing details; a patient may need eligibility, risks and clinician qualifications. Write the answer in the language and jurisdiction of the audience, state who it applies to, and link the source of any claim. Search accessibility, useful content and trustworthy references remain important even when the final answer appears in an AI interface.
Choose evidence appropriate to the risk
For healthcare, finance and legal topics, name the responsible reviewer and cite current primary guidance. Include the effective date and applicable region; do not present general information as individual professional advice. For products, keep specifications, availability and prices consistent with the visible offer. For education or travel, verify eligibility, schedules, accessibility and cancellation details. No schema type or publishing frequency substitutes for accurate underlying information.
A worked example: a software integration question
For “Does this service work with our CRM?”, a useful page identifies supported versions, required permissions, setup steps, limitations and who owns support. A short comparison table can distinguish native integration, API integration and unsupported combinations. Link the actual documentation rather than inventing benchmark results. If the integration changes, revise the answer and dated limitations together; adding more general GEO paragraphs does not help the buyer.
Measure visibility without inventing industry benchmarks
Build a fixed set of relevant questions for each market and language. Record the engine, date, response, correct mention and cited URL. Monitor referral visits and business outcomes separately because many AI mentions produce no identifiable click. A before-and-after difference is an observation, not proof that schema or llms.txt caused it. There is no universal citation lift, market-share figure or guaranteed time to result applicable to every industry.
Evidence and next actions
| Check | Evidence to retain | Action |
|---|---|---|
| Healthcare | Current guidance, reviewer credentials, region | Verify safety claims before publication |
| Finance and legal | Effective date, regulation, scope | Separate facts from advice |
| Commerce | Live price, availability, product specification | Sync visible facts and matching structured data |
| Software | Versioned documentation and tested steps | Explain prerequisites and failure cases |
| Local services | Actual service area, hours and contact details | Remove unsupported location claims |
Implementation checklist
- Choose questions specific to the buying or service decision.
- State the language, region and eligibility clearly.
- Attach primary sources to claims that affect a decision.
- Use structured data only for information visible on the page.
- Distinguish search crawling from model-training controls.
- Measure each audience with its own unchanged prompt set.
A repeatable workflow
- 1Establish a baseline
Save the page URL, date, language, target market and exact questions before editing. Record what the page actually says and what each tested answer cites; a mention without a source link is not a citation.
- 2Make one coherent change
Resolve the clearest failure first, then check the published page rather than only an editor preview. Keep an implementation log so unrelated redesigns, campaigns or product changes are not mistaken for the effect of this work.
- 3Repeat and compare
Repeat the same questions and technical checks after deployment. Keep engines and measurement conditions consistent, report sample size, and inspect answer accuracy alongside citations. A single response is not a stable ranking.
More questions answered
- Does this guarantee an AI citation?
- No. A crawlable, accurate page can still be omitted. Retrieval, source selection and generated answers vary between products and requests; these checks improve the evidence available, not guarantee placement.
- How do I tell whether an improvement worked?
- Compare like-for-like checks and retain the underlying evidence. Track correct brand mentions, source-linked citations and qualified referral visits separately. Do not call a technical score a traffic forecast or attribute every change to one edit.

Run a full GEO + AEO scan on your siteFrequently asked questions
- What is an AI visibility checker?
- It audits the technical signals that decide whether ChatGPT, Perplexity, Gemini and Claude can read, trust and cite your site: AI crawler access in robots.txt, llms.txt, structured data, metadata, sitemap and answer-shaped copy — and turns them into one score you can improve.
- How is the AI visibility score calculated?
- Eleven weighted checks are fetched live from your domain. Crawler access and structured data carry the most weight; a hard block or a missing entity scores zero for that check. Pass earns the full weight, a warning earns partial credit, and the total is normalised to 0–100.
- How is this different from the brand mention tracker?
- The checker audits whether your site is readable and citable — the foundation. The AI Brand Mention Tracker and AI Rank Tracker ask live models whether you actually get mentioned today. Fix what the checker finds first; tracking before fixing just measures the same problem repeatedly.
- Does the check touch my pages or cost anything?
- No signup, no cost. The checker fetches your homepage, robots.txt, llms.txt, sitemap.xml and .well-known/ai-plugin.json exactly as an AI crawler would, and nothing is stored.
- What score should I aim for?
- Above 90. Below 75 you are leaving citation chances on the table; any single hard fail — a blocked GPTBot or missing structured data — can zero your visibility on an engine regardless of content quality.
