Common questions
Is the check really free?
Yes. No sign up and no email needed.
Does a high score mean ChatGPT will recommend me?
No one can guarantee that. The score shows whether the technical basics are in place. Recommendations also depend on content and on mentions on other trusted sites.
What does it read on my site?
Only public pages: the home page, robots.txt, sitemap.xml and llms.txt. Nothing is stored.
How do I fix what failed?
Each result explains what to change. Most fixes are small changes to your site or its files. If you prefer, we can do it for you.
