Any public page works. Your home page gives the most complete result.
We fetch robots.txt, llms.txt and the raw page from our servers. Nothing is installed or changed on your site.
Each finding comes with a plain-English explanation and the exact line or setting to change.

No. GPTBot collects training data. ChatGPT search uses a separate crawler, OAI-SearchBot, and ChatGPT-User when someone asks it to open a page. You can block GPTBot and still appear in ChatGPT answers, as long as the other two are allowed.
llms.txt is a plain-text file at the root of your site that summarises what the site is about and links to its most useful pages. It is an emerging convention, not a standard, so a missing file is a suggestion rather than a problem.
Most AI crawlers download your HTML and stop there. If your text only appears after JavaScript runs, those crawlers see an empty page and have nothing to quote or recommend.
Yes. The check is free and needs no account. You only need an account for weekly monitoring and the tools that fix what the check finds.
No. We only read public files, the same way a search engine or AI crawler would. Nothing is installed, submitted or stored on your site.
An SEO audit looks at how you rank in search results. This check looks at whether AI assistants are allowed to read your site and can understand who you are, which decides whether they can mention you at all.
Reguweb writes your robots.txt rules, llms.txt and business schema, rechecks every day, and tracks what AI assistants say about you.
