You can measure Core Web Vitals by running a full-page performance audit that traces network dependency chains and reports metrics like FCP, LCP, TBT, CLS, and Speed Index to identify render-blocking resources.
Profiling page loads and optimizing Lighthouse scores requires running comprehensive performance traces that assess resource timing, caching issues, and accessibility gaps across desktop and mobile experiences.
Performance tracing diagnoses web performance bottlenecks by analyzing resource timing and network dependency chains during page loads, isolating specific render-blocking resources and caching issues slowing down the site.
Yes, you need Chrome DevTools MCP access to run performance traces and report Core Web Vitals metrics like FCP, LCP, and CLS for both desktop and mobile experiences.
Yes, a web performance audit can assess caching issues and accessibility gaps alongside measuring Core Web Vitals, providing a comprehensive view of site speed and rendering bottlenecks.
Your page load may remain slow due to render-blocking resources, network dependency chains, or unoptimized caching issues, which a full performance trace can identify by analyzing resource timing beyond images.
