A technical SEO audit should include a comprehensive review of the website's architecture, codebase, content structure, and performance. It should assess any potential issues with indexing or crawling that could be preventing optimal visibility in search engine results pages (SERPs). Additionally, it should check for broken links and duplicate content; evaluate page speed optimization; analyze meta tags and titles; identify keyword opportunities; verify proper canonicalization is being used; inspect robots.txt files to ensure only relevant URLs are blocked from crawling; test site navigation usability to maximize user experience on SERP rankings. Lastly, it must also monitor the website‣s security protocols to prevent malicious attacks from hackers.
