You can audit Core Web Vitals by analyzing field data from CrUX and lab data from Lighthouse for a target URL. This process diagnoses LCP, CLS, INP, and TTFB metrics to identify speed and rendering issues affecting search rankings.

Diagnosing poor PageSpeed involves analyzing payload weight, third-party script impact, and image loading configurations. By evaluating both real user data and lab measurements, you can pinpoint specific bottlenecks like render-blocking scripts or uncompressed assets.

To optimize images and fonts for rendering performance, you should evaluate image formats, implement lazy loading, and adjust fetch priority. This reduces payload weight and improves perceived loading speed for better Core Web Vitals scores.

Yes, the performance audit evaluates mobile parity alongside desktop metrics. By assessing field and lab data across different devices, it identifies discrepancies in loading speed and rendering behavior to ensure consistent user experience.

A high TTFB often results from server processing delays or inefficient caching policies. Analyzing server response times and optimizing caching rules for static assets helps reduce TTFB and improves overall page speed metrics.

Yes, you can assess third-party script impact by analyzing total payload weight and the number of requests. This evaluation identifies how external scripts affect loading performance and provides actionable recommendations to mitigate their impact.
