About this scan
Six checks for one page and host, in up to 30 seconds. External sitemaps are not visited. DNS records do not prove correct mail delivery.
Anyone with the result link can view the report. Reports expire after seven days. The public URL shows the latest available scan for that hostname and tool, so a later scan can change what it displays.
Query values in submitted and captured HTTP URLs and sensitive response headers are redacted. Hostnames, paths and query parameter names remain visible. Use public URLs without confidential information.
A snapshot, not a security guarantee.

What does SiteAudit check?
SiteAudit combines six checks for one page and its host: HTTP headers, redirects, TLS, page SEO, robots and sitemaps, and DNS. It works within a 30-second scan budget. Review each module’s evidence to see what was measured and which checks could not complete.
Does SiteAudit crawl my whole website?
No. It checks the URL you submit and supporting information for that host. It does not discover every page or run JavaScript. Audit representative URLs from different templates, such as an article, product page and homepage, to investigate a broader site change.
A practical technical SEO audit checklistDoes a good audit score mean my page will rank higher?
The score summarizes this tool’s technical checks. It does not measure search rankings, content quality, backlinks or whether Google has indexed the page. Use individual findings to plan fixes and Search Console to investigate search visibility.
Why is part of my audit marked incomplete or not checked?
A module may lack usable evidence because of a timeout, response-size limit, connection failure or unsupported response. That is not the same as a confirmed problem with your site. Review the explanation, resolve any access issue and run the audit again.
A practical technical SEO audit checklistCan robots.txt stop a page appearing in Google?
A robots.txt crawl block alone does not reliably prevent indexing. Google must be able to read a noindex instruction to apply it. SiteAudit shows relevant evidence, but does not confirm Google’s indexed state or fully simulate its crawler.
