A technical SEO audit is the foundation of a healthy, high-ranking website. While keywords and content drive relevance, technical SEO ensures that search engines can properly crawl, index, and rank your pages. By reviewing crawlability, indexation, Core Web Vitals, and structured data compliance, you can identify hidden issues that may limit your site’s visibility.
This guide walks you through the essential steps of a technical SEO audit so you can improve your site’s performance and future-proof your rankings.
