What we check
On each page: a status other than 200, redirects (worse when they go to the home page or end broken), a block in robots.txt, noindex, a canonical that is missing or points to another URL, HTML with no content before JavaScript runs, a title that is missing, generic or not 40 to 60 characters long, and a missing description.
Across pages: titles and descriptions that repeat, and one plan with different prices, also in llms.txt. The free sample checks the first 20 sitemap URLs on the same host.
How to use the result
Start with the three issues at the top: they cost the most search traffic. Each issue shows the pages it touches and the fix.
The result stays for one hour. After you publish the fixes, run the audit again to see the new score.
