Core Web Vitals Optimization
Google evaluates pages based on Core Web Vitals: Largest Contentful Paint (LCP) for loading time, First Input Delay (FID) or Interaction to Next Paint (INP) for interactivity, and Cumulative Layout Shift (CLS) for visual stability. As an SEO agency, I systematically analyze these metrics using Chrome UX Report, PageSpeed Insights and the Web Vitals JavaScript library. I optimize critical rendering paths, implement preloading strategies and eliminate layout shifts. The result: Green values across all Core Web Vitals and a measurable ranking boost in Google search.
Technical SEO Optimization
A comprehensive SEO and performance audit forms the foundation of every optimization. Using Lighthouse, WebPageTest, GTmetrix and Chrome DevTools, I analyze your website in detail. The audit report documents all bottlenecks: from oversized JavaScript bundles to unoptimized images to render-blocking resources. For each finding, you receive concrete, prioritized recommendations with estimated impact. Waterfalls and filmstrips visualize loading behavior. This way you know exactly where optimization potential lies and which measures will have the greatest effect.
