What does this free SEO audit check?
Our free SEO audit checks technical SEO issues including broken links, redirect chains, noindex conflicts, missing structured data, thin content, duplicate titles, Core Web Vitals (LCP, INP, CLS), internal link structure, sitemap issues, and AI crawler accessibility.
How is this tool different from other free SEO audit tools?
Unlike other free SEO audit tools that just list issues, SiteForensics connects multiple findings to reveal root causes through investigations.
