Semrush and Ahrefs Site Audit alternative for website owners
Updated
Semrush and Ahrefs Site Audit are thorough tools for search. If you just want to know what's wrong with your own site, use Sitecomb.
Checking a whole website usually takes several tools. Sitecomb checks six areas at once, and its full report gives a plain fix for each problem.

What Semrush and Ahrefs do well
- Depth on search. Both read many pages and find search problems a quick check won't.
- Ahrefs is free for your own site. Prove you own it and you get its Site Audit free, up to 5,000 pages a month.
Where Sitecomb is different
- No login, any site. Check your own site, a competitor's or a client's.
- Beyond search. Privacy notices, contact details and email anti-spoofing are in the same report.
- Plain fixes. Each finding says what it means and what to do, in one short report.
