Overview

Core Web Vitals focus on loading performance, responsiveness and visual stability. Improve them by fixing the real bottlenecks affecting visitors rather than chasing a single score.

Measure Representative Pages

Test the homepage, key landing pages, posts and product templates. Compare field data and lab tests to identify patterns.

Improve LCP

Optimize the main above-the-fold image, reduce server response time, preload important resources when appropriate and avoid delaying critical content.

Make one meaningful change at a time and test the result before moving to the next step. This makes troubleshooting much easier.

Improve INP

Reduce unnecessary JavaScript and heavy third-party scripts. Keep interactions lightweight so the browser can respond quickly to user input.

Reduce CLS

Reserve dimensions for images, banners and embeds. Avoid inserting unexpected content above elements that have already rendered.

Retest After Changes

Measure again after each meaningful optimization. Performance work is iterative and should be validated on real devices.

Final Checklist

Review the changes on desktop and mobile, confirm important links and interactions, clear relevant caches, and keep a recent backup before publishing major updates.
