SEO Technical Audit
SEO Technical Audit is an SEO topic covered in SeoWiki.

Key takeaways
- A technical SEO audit focuses on the non-content parts of a site, especially crawlability, indexability, rendering, speed, security, and architecture.
- Its core question is whether search engines can reach important pages and then store and show them in search results.
- Google Search Console is a primary source for audit data, especially coverage/indexing, crawl stats, mobile usability, manual actions, and security issues.
For SEO practitioners, it reveals hidden blockers such as blocked pages, crawl errors, duplicate URLs, and slow or unstable pages that can suppress organic visibility. It also helps prioritize fixes that improve how Google crawls, indexes, and renders important content.
