How to Run a Technical SEO Audit: A Step-by-Step Guide
Technical issues quietly cap how well even great content can rank. Here's how to find and prioritize them.
Technical SEO issues are easy to overlook because they don't show up in the content itself — but they quietly cap how well even great content can rank. Here's a step-by-step approach to auditing your site.
1. Check Crawlability
Start with your robots.txt and XML sitemap. Make sure search engines aren't accidentally blocked from crawling important sections of the site, and that the sitemap only includes pages you actually want indexed.
2. Review Indexation
Use Google Search Console's Index Coverage report to see which pages are indexed, excluded, or flagged with errors. Investigate any unexpected exclusions — they often point to noindex tags, canonical issues, or duplicate content.
3. Audit Site Speed and Core Web Vitals
Slow-loading pages hurt both rankings and conversions. Check Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint using PageSpeed Insights, and prioritize fixes on your highest-traffic pages first.
4. Check for Duplicate Content
Look for near-identical pages, unresolved URL parameter variations, and missing or inconsistent canonical tags. Duplicate content splits ranking signals across multiple URLs instead of consolidating them.
5. Verify Mobile Usability
With mobile-first indexing, your site needs to work well on mobile, not just desktop. Check for text that's too small, tap targets that are too close together, and content that's hidden or broken on smaller screens.
6. Review Structured Data
Validate your schema markup (Organization, Article, Service, etc.) using a structured data testing tool. Errors here can prevent rich results from showing up in search.
7. Check Redirect Chains and Broken Links
Long redirect chains slow down crawling and dilute link equity. Fix broken internal links and simplify redirect chains down to a single hop wherever possible.
8. Prioritize by Impact
Not every issue needs to be fixed immediately. Rank findings by how many pages they affect and how much traffic those pages get, then work through the highest-impact issues first.
A technical audit isn't a one-time project — revisit it every few months, especially after any site migration, redesign, or major content push, to catch new issues before they quietly erode your rankings.
