Is your website visible to AI search engines like ChatGPT?
AI search visibility is whether AI tools can reach your website, read its text, and understand what you do well enough to use you when they build an answer. CRO9 tests your page as six named AI crawlers, compares each result against a real browser request, and returns a 0–100 score with the exact issues to fix.

Why ranking on Google is no longer enough
Google search returns a list of links. AI search returns one answer, assembled from a small set of sources the engine could actually reach and parse. Those are different selection problems. A page can hold a top organic position and still be unreachable to the crawler that assembles the answer — because ranking is decided on a copy Google already has, while an AI answer depends on a fresh request that your server, your robots.txt or your JavaScript can refuse. Ranking is not access, and access is where most sites quietly fail.
We are not going to hand you a conversion-lift statistic we have not measured ourselves. What we can show you is something more useful and entirely checkable: whether the engines can get in the door at all.
The failure that is invisible to every other tool
A site can return a perfect 200 OK to your browser, to a curl request, and to Googlebot — while returning 403 Forbidden to GPTBot and ClaudeBot. Bot-protection features on modern hosting platforms do exactly this, often with a single toggle labelled something harmless like “AI bots”. Nothing warns you. Your analytics look normal. Your rankings do not move. You simply stop existing inside AI answers.
We know because it happened to cro9.com. Our robots.txt explicitly invited eleven AI crawlers in. Our firewall was turning them away at the door. The site that sells AI visibility was, for a period, invisible to AI — and no ranking tool, uptime monitor or analytics dashboard we ran ever mentioned it. We found it by fetching our own site as GPTBot and comparing the response to a browser request. That comparison is now the first thing this scanner does to yours.
What the score actually measures
Three dimensions, because any one of them alone gives a false green.
Status
Does your server actually answer that crawler — or quietly block it? Measured against a real browser request in the same run, because a site can return 200 to a browser and 403 to GPTBot.
Content
Does the crawler receive readable words, or an empty shell? Client-rendered pages return 200 with almost no text. We count the visible words the bot actually gets.
Permission
Does your robots.txt allow that specific bot? A site can serve a perfect page and still tell the crawler, in writing, to go away.
Tested as these six crawlers
And whether your content is built to be answered with
Reaching your page is step one. The second half of the score — Answer Engine Optimization — grades the page itself across ten weighted factors:
Every issue comes back in plain language with what to change — not a jargon dump you need a developer to translate first.
AI visibility vs. traditional SEO tools
| Traditional SEO tools | CRO9 AI visibility | |
|---|---|---|
| What it measures | Keyword rankings and backlinks | Whether AI engines can reach, read and understand you |
| How it tests | Queries an index | Fetches your page as six named AI crawlers, against a browser control |
| Content advice | Hit a word count | Answer the real question, first and clearly |
| Blind spot | Assumes clicks still happen the old way | Accounts for zero-click, AI-answered searches |
| What it will not claim | — | That we can guarantee a citation. Nobody can. |
How to fix a weak score
- 1Unblock the crawlers
Check your host’s bot-protection rules and your robots.txt. This is the one that silently zeroes everything else.
- 2Answer in the first paragraph
Put the direct answer to the page’s core question in the opening lines, before the context.
- 3Shape headings as questions
Use the phrasing people actually type, then answer it immediately underneath.
- 4Add a real FAQ block
Genuine questions, plainly answered, with FAQPage schema attached.
- 5Ship valid structured data
Organization, WebPage and FAQPage at minimum, so an engine knows what your business is.
None of this is a rebuild. It is knowing which five things to change — which is exactly what the score gives you.
Frequently asked questions
What is the difference between SEO and GEO?
SEO helps your page rank in a list of search results. GEO (Generative Engine Optimization) makes sure AI tools can reach your page, read it, and understand it well enough to use it when they build an answer.
Can a website rank well on Google but still be invisible to AI search?
Yes, and it happens often. The two are graded on different signals, and access is separate from ranking: a page can hold a strong Google position while an AI crawler is being blocked at the server or in robots.txt.
Do I need to rebuild my website to improve my AI visibility score?
No. Most fixes are structural and content-based — clearer answers, question-shaped headings, valid schema, and unblocking AI crawlers. None of that requires a redesign.
How long does the AI search visibility scan take?
About ten seconds, with no signup. You get the score and the specific issues immediately.
Does a good score mean ChatGPT will recommend my business?
No, and we will not tell you otherwise. No tool can promise a citation — answers vary by prompt, by user and by day, and no engine publishes a "do you know this site" API. What we measure is whether the engines can reach and read you at all, which is the prerequisite. Reachability is a fact. Citation is a guess. We report the fact.
Is AI search visibility only important for large companies?
No. Smaller sites often gain the most, because AI answers frequently pull from the page that addresses a specific question directly rather than the biggest brand that never quite answers it.
