FAQ<br>Common questions about AI visibility
What is an AI visibility score?It shows how many AI crawlers and search engines can reach your site right now, out of 100 points. The score combines two signals: whether each AI agent is allowed to access your pages, and whether you publish an llms.txt file.
What is robots.txt?robots.txt is a text file at the root of your domain that tells crawlers, including search engines and AI bots, which parts of your site they can access. It's the same file that already controls how Google indexes your pages.
What is llms.txt?llms.txt is a newer file, published at yourdomain.com/llms.txt, that gives AI systems a clean, direct summary of your site's content. It isn't required yet, but publishing one is an easy way to tell AI answer engines what your site is about.
