FAQ

Questions about SEO Audit Tools

Which audit tool should I start with?

Start with the Free SEO Audit Checker for a broad page review, then use focused tools such as HTTP status, redirects, headings, images, and broken links to investigate specific issues.

Do these tools use private analytics or Search Console data?

No. These audit tools use public URLs, visible page HTML, response headers, or browser-side input. They do not connect to private Google Analytics or Search Console accounts.

How these tools handle checks, data, and limitations

Most tools run in your browser or fetch public URLs only. They do not use private Google Analytics, Search Console, or account data.

Use results as practical diagnostics, then validate critical fixes with official platform tools, crawlers, and production checks before deployment.

  • Pages blocked by robots.txt, login walls, bot protection, heavy JavaScript, or network timeouts may return incomplete results.
  • Validate critical fixes with official Google tools such as Search Console, Rich Results Test, Lighthouse, and your own crawl data.
