AI Visibility Audit
Check whether ChatGPT, Perplexity, and other AI crawlers can actually see and understand your website.
What the AI Visibility Audit checks
ChatGPT, Perplexity and other AI assistants can only cite a page their crawlers are allowed to fetch and can read. The audit checks both for any public URL and gives a score out of 100: 45 points for access and 55 for readability.
Access is your robots.txt rules for five AI crawlers: GPTBot, OAI-SearchBot, PerplexityBot, Google-Extended and ClaudeBot. Readability is whether the page carries JSON-LD structured data and whether its text is in the raw HTML, since most AI crawlers do not run JavaScript. The audit also reports whether you have an llms.txt file, without scoring it.
How to use it
- 1Enter your homepage URL, or the URL of the page you most want AI assistants to cite.
- 2Run the audit. It reads your robots.txt, looks for llms.txt and fetches the page the way a crawler would.
- 3Check the access section: each crawler is marked allowed or blocked.
- 4Check the readability section: the structured data types found, and whether the text is visible without JavaScript.
- 5Work through the fixes in the order listed, then run the audit again to confirm the score moved.
How to act on the results
- A blocked search crawler keeps you out of that assistant’s answers. OAI-SearchBot feeds ChatGPT search and PerplexityBot feeds Perplexity; unblock them if you want to be cited.
- GPTBot, ClaudeBot and Google-Extended are mostly about using your content to train or ground models. Blocking them is a separate business decision, and blocking Google-Extended does not affect your Google Search rankings.
- If the text is not in the raw HTML, render the page on the server or prerender it. A crawler that sees an empty shell has nothing to cite.
- If no structured data was found, start with Organization on your homepage and Article on your blog posts. It tells machines who wrote a page and what it is about.
Frequently asked questions
Is the audit free?
Yes. There is no signup and no card. You can run up to 10 checks an hour, shared across all the free tools.
Does a perfect score mean ChatGPT will cite me?
No. Access and readability are the preconditions. Being cited depends on whether your page answers the question better than the other pages the assistant can read.
Do I need an llms.txt file?
It is optional. llms.txt is a proposed standard, and the major AI assistants have not said they use it, so the audit reports whether you have one but does not score it.
Will unblocking AI crawlers hurt my Google rankings?
No. Googlebot is a separate crawler, and robots.txt rules for AI crawlers do not change how Google Search crawls or ranks your pages.
