Core Web Vitals and website speed optimization
Core Web Vitals optimization addresses loading, responsiveness and visual stability using measurements from real users and diagnostic tests.
Core Web Vitals and website speed optimization: what should you review?
Core Web Vitals describe three aspects of page experience: Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS). LCP concerns visible loading, INP concerns response to interactions, and CLS concerns unexpected movement.
Separate field evidence from a laboratory test
Core Web Vitals describe three aspects of page experience: Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS). LCP concerns visible loading, INP concerns response to interactions, and CLS concerns unexpected movement. These metrics measure different problems. [1]
A speed review should record the tested URL, device category, measurement source and date. A laboratory run can help isolate a large image or blocking script, but it does not replace field evidence from visitors. Where field data is unavailable, report the gap.
Prioritize changes against the actual template: reserve image space, review third-party code and examine the main content request. Retest the affected pages under comparable conditions. Avoid presenting one fast run as proof that every page loads within the same time.

Questions and answers
Does a good laboratory score prove field performance?
No. Keep laboratory diagnostics and real-user measurements separate, with their device, period and source identified.
