How to Run a Technical SEO Audit Without Getting Lost

Technical SEO audits often produce hundreds of warnings. The skill is in deciding which issues actually affect visibility and revenue. This guide focuses on the checks that matter most.

Crawl the site like a search engine

Use a crawler such as Screaming Frog or Sitebulb to list every URL, status code, title, canonical and internal link. Compare the crawl with your XML sitemap and Search Console's indexing report. Differences reveal orphan pages, accidental duplicates and pages Google is ignoring.

Check indexing signals

Look for conflicting signals: pages in the sitemap that are noindexed, canonicals pointing to redirected URLs, or parameter URLs being indexed. Each important page should return status 200, be self-canonical and be linked internally.

Review redirects and errors

Replace redirect chains with single 301 redirects, fix internal links that point to redirected or broken URLs, and make sure your 404 page returns a real 404 status. Soft 404s confuse search engines and waste crawl activity.

Measure page experience

Use PageSpeed Insights and Search Console's Core Web Vitals report to identify slow templates rather than individual pages. Large images, render-blocking scripts and heavy tag managers are common culprits. Fixing one template can improve thousands of pages.

Validate structured data

Test key templates with the Rich Results Test. Use schema types that match visible content, such as Organization, BreadcrumbList, Product, Article and LocalBusiness. Markup that describes content users cannot see can violate guidelines.
