What is a technical SEO audit?
A technical SEO audit is a review of the behind-the-scenes parts of your site that affect how well it can be found. It looks at speed, crawlability, indexing, mobile friendliness, structure, and errors. The goal is to remove anything that blocks search engines or confuses them. A clean technical base does not guarantee rankings, but a broken one will hold back even great content, so this check comes first.
The classic checks that still matter
- Make sure important pages are indexable and not blocked.
- Fix broken links, errors, and bad redirects.
- Improve page speed and core web vitals.
- Confirm the site works well on mobile.
- Keep a clean sitemap and logical structure.
The 2026 AI-search additions
- Check which AI crawlers you allow in robots.txt.
- Add clear schema so machines understand your pages.
- Make sure key content is in the HTML, not hidden behind scripts.
- Break content into clean chunks with clear headings.
- Review your logs to confirm AI bots reach your best pages.
How to run your audit
Work through the classic checks first, since a broken base undermines everything else. Then add the AI-search items so you are ready for how models read your site. Pair this audit with sensible AI crawler settings and log file analysis. Use Google Search Console to spot indexing and speed issues for free.
