The audit covers crawlability, indexability, site speed and Core Web Vitals, mobile optimisation, HTTPS implementation, structured data, duplicate content, internal linking, and URL structure. Conducted using a combination of Google Search Console data, crawling tools (Screaming Frog, Ahrefs), and browser-based analysis, a thorough technical SEO audit typically takes four to twelve hours depending on site complexity. Technical SEO audits should precede any content or link building strategy — there is no point investing in content if the site cannot be crawled properly, or building links to pages that are inadvertently noindexed. The audit creates a prioritised list of technical fixes ordered by impact, providing a clear action plan for improving the site's technical foundation. ## Technical SEO audit steps - 1. Crawl the site — use Screaming Frog, Ahrefs, or Semrush to crawl all pages and identify technical issues - 2. Review Google Search Console — check Coverage, Core Web Vitals, Rich Results, and Manual Actions reports - 3. Check crawlability — review robots.txt, crawl errors, and blocked resources - 4. Audit indexation — compare crawled pages against indexed pages; identify unintended noindex pages - 5. Check redirects — identify redirect chains, redirect loops, and broken redirects - 6. Review Core Web Vitals — mobile and desktop CWV scores across the site - 7. Audit structured data — validate schema markup on key page types - 8. Check internal linking — identify orphan pages, shallow pages, and anchor text patterns - 9. Review duplicate content — canonical tags, parameterised URLs, and thin pages - 10. Prioritise issues — categorise by impact (critical/high/medium/low) and effort required Professional technical SEO audit How often should a website get a technical SEO audit? A comprehensive technical SEO audit should be conducted at minimum annually for established sites. Major technical audits should also be conducted before and after any significant site change — CMS migration, URL restructure, redesign, or platform change. Automated monitoring (Google Search Console alerts, Ahrefs weekly crawls) can catch new technical issues between formal audits, but automated alerts cannot replace the strategic judgment applied in a manual audit. What tools do technical SEO audits use? The standard toolkit for technical SEO audits: Google Search Console (free, essential — the primary data source), Screaming Frog SEO Spider (crawling tool, free up to 500 URLs, paid for larger sites), Google PageSpeed Insights or Lighthouse (performance analysis), Ahrefs or Semrush (link analysis, keyword data, site audit features), Chrome DevTools (rendering and network analysis), and the Schema Markup Validator (structured data validation). Some auditors also use log file analysis tools to examine actual Googlebot crawl behaviour from server logs. ### Ready to improve your Technical SEO? Get a free consultation from our expert team.
