What is the Crawler Control Tool?

The problem: most site owners have a robots.txt file they’ve never properly checked, and almost nobody knows what llms.txt does or whether they even need it.

That leads to broken indexing, blocked search engines, or AI crawlers accessing content you didn’t mean to share. This guide fixes that by showing exactly how the Crawler Control Tool works and how to use it safely.

The Crawler Control Tool helps you analyze and test two crawler instruction files on your website: robots.txt and llms.txt. These files tell search engines, AI crawlers, and other bots which parts of your site they are allowed to access and which parts they should avoid.

Instead of guessing or editing blindly, the tool shows you what’s happening, what’s wrong, and what to improve.
