Why Perform a Technical SEO Audit?

A technical SEO audit is an exhaustive analysis of your website's architecture, code, and overall performance from the perspective of search engines like Google and Bing. Even if your website features a modern design, an elegant user interface, and carefully written content, invisible technical bottlenecks — such as slow page loading, missing canonical tags, internal 404 errors, or misconfigured robots.txt files — can severely suppress your rankings. BACKR's free audit tool runs on a high-performance distributed infrastructure. Powered by our ultra-fast HTTP crawler and the official Google Lighthouse 13 engine, BACKR evaluates over 50 strategic parameters in 30 to 60 seconds. You receive an overall score out of 100, a detailed assessment of Core Web Vitals metrics (LCP, CLS, TBT), and a prioritized list of corrective tasks complete with copy-paste code snippets for your technical team.
