Technical SEO Audit Checklist for Websites

A technical SEO audit checklist makes sure search engines can find, read and trust your site. Run it every quarter.

Crawling and indexing

• Is robots.txt blocking important pages by mistake?
• Is there an XML sitemap submitted in Google Search Console?
• Do key pages show as indexed?
• Are duplicate pages using canonical tags?

Site structure

• Can any page be reached within a few clicks?
• Are URLs short and readable?
• Do important pages have internal links pointing to them?

Speed and mobile

• Do pages load quickly on a mobile connection?
• Are images compressed and sized correctly?
• Is the layout usable on small screens without zooming?

Errors

• Fix broken links and 404 pages.
• Redirect old URLs to the most relevant new page.
• Avoid long redirect chains.

Security and markup

• Use HTTPS on every page.
• Add structured data where it is accurate, such as articles and breadcrumbs.

Prioritise

List problems by impact and effort. Fix the ones that affect many pages first.
