Semrush Site Audit alternative: a technical SEO audit in ChatGPT
Semrush is a full marketing platform: keyword research, competitor analysis, position tracking and a site audit in one plan. Sitewalk does one job: the technical SEO audit, started from ChatGPT. If the audit is all you need, Sitewalk can be enough. If you need rankings and keywords too, Semrush covers ground Sitewalk does not.

Can I audit a site I do not own?
Yes, any public site, within the page limits and the site's robots.txt.

A small site usually takes a few minutes and a 500-page audit 20 to 60 minutes.
