Can ChatGPT, Perplexity and Claude actually read your site?

Ranking on Google says nothing about this. We check the four things that decide whether an answer engine can fetch, parse and quote you — crawler access, server-rendered content, schema markup and /llms.txt. 30 seconds, no sign-up.

THE BLIND SPOT

A perfect SEO score can hide a total AI blackout.

Googlebot and the AI crawlers are different bots obeying different lines in the same file. When a site blocks GPTBot, nothing breaks in a way you would notice: Google keeps crawling, rankings hold, Search Console stays green, GA4 shows nothing unusual. There is no alert, because from every dashboard you own, nothing happened.

The most common cause is not a decision — it is inheritance. A robots.txt written before 2023 that allowlists the crawlers of its day still parses perfectly today, and quietly excludes every AI crawler invented since. The second most common cause is a client-rendered front end: the page looks full in a browser, and arrives empty at anything that does not run JavaScript.

What this scan does not do: it will not tell you whether ChatGPT cites you today. It tells you whether it can — access, readability, extractability. Citation share is measured by probing live AI answers for your queries over time, which is Alice’s job once you connect Search Console. But capability comes first: an engine that cannot read you will never cite you.

THE FOUR CHECKS

What we test, and why each one decides a citation.

01
AI crawler access
Whether each engine is actually allowed in.
We resolve your robots.txt the way a bot does and report each AI crawler separately — GPTBot and OAI-SearchBot (ChatGPT), ClaudeBot, PerplexityBot, Google-Extended and friends — as allowed or blocked. robots.txt groups are exclusive, so a file that names Googlebot in its own group silently blocks every crawler invented since.
02
Server-rendered content
Whether your words exist before JavaScript runs.
We read the raw HTML your server returns, with no browser and no JavaScript execution, and report whether the title, meta description, H1 and body copy are actually in it — plus the word count that survived and the framework we detected. A React or Vue app that renders entirely client-side can look empty to a crawler that does not execute scripts.
03
Schema.org markup
Whether your facts are extractable, not just readable.
We list the structured-data types found on the page and flag whether you have entity markup (Organization, Product), answer markup (FAQPage, HowTo) and article markup. Schema is how a model lifts a specific claim out of a wall of prose and attributes it to you rather than paraphrasing it away.
04
/llms.txt
Present or absent — graded as optional.
We check for the file and report its size. We also tell you plainly that the convention is experimental and unproven for citations, because a free tool that grades you red for missing an unratified standard is selling anxiety, not information.

Every finding comes back graded healthy / warning / error with the specific issue and the fix — not a number with no explanation.

SAME SCAN, OTHER HALF

Looking for the classic SEO side?

This page leads with AI visibility because that is where most sites are quietly broken. The same scan also grades on-page SEO, crawlability, search-index presence and your measurement tags — if that is the angle you came for, the free SEO + AI visibility check frames the same report around search.

Want the full picture — which queries you rank for, which AI answers cite you, and where paid spend is leaking? Connect Search Console, GA4 and Google Ads with one click after the scan, and Alice starts from the results you just got.

QUESTIONS

AI visibility, answered.

How do I check if ChatGPT can see my website?+

Three things have to be true: your robots.txt must allow the AI crawlers (GPTBot and OAI-SearchBot for ChatGPT, ClaudeBot for Claude, PerplexityBot for Perplexity), your page content must exist in the raw HTML rather than being rendered by JavaScript in the browser, and your key facts should be marked up with schema.org so they can be extracted cleanly. The scan on this page tests all three against your live URL in about 30 seconds.

Is an AI visibility check different from an SEO check?+

Yes, though they overlap. An SEO check asks whether Googlebot can crawl, index and rank a URL so a human clicks it. An AI visibility check asks whether an answer engine can fetch, parse and quote your content inside a generated answer where there may be no click at all. The most common failure mode is a site that scores well on SEO and badly on AI visibility, because Googlebot is explicitly allowed in robots.txt while the AI crawlers — all invented after 2023 — are not.

What is GEO (Generative Engine Optimization)?+

GEO is the practice of getting your brand, URL or content cited inside an AI-generated answer — Google AI Overviews, ChatGPT, Perplexity, Claude, Gemini — rather than ranking as a blue link. AEO (Answer Engine Optimization) is the closely related discipline of structuring content so a machine can lift a clean, complete answer out of it. Neither replaces SEO; they are what you do on top of it when the user may never click through.

Does blocking GPTBot in robots.txt hurt my traffic?+

It does not hurt your Google rankings — GPTBot has nothing to do with Googlebot — which is exactly why blocking it is so easy to miss. Nothing in Search Console or GA4 shows a symptom. What it does is remove your site from the pool of sources ChatGPT can read and cite. Blocking is a legitimate choice if you do not want your content used for training, but it should be a decision you made on purpose, not one a robots.txt file inherited from 2019 made for you.

Is /llms.txt worth adding?+

Probably harmless, currently unproven. /llms.txt is a proposed convention for giving language models a curated map of your site, and no major AI engine has publicly committed to honouring it as a ranking or citation input. We report whether you have one because it costs nothing to check, but we grade it as optional and would not put it ahead of fixing crawler access or server-rendered content.

Does this scan tell me whether ChatGPT actually cites my site?+

No — and be wary of any free tool that claims it does. This scan tests capability, not outcome: whether the engines are able to reach, read and extract your content. Measuring actual citation share requires repeatedly probing live AI answers for your buyer queries over time, which is what Alice does once you connect Search Console. Capability first, though: a site the crawlers cannot read will never be cited no matter how the tracking looks.
