Core Web Vitals: 5 Steps To Improve Website Experience

Core Web Vitals measure loading, responsiveness and visual stability. The current set is Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS). Older references to First Input Delay in this article have been corrected.

1. Measure The Actual Problem

Use field data where available and lab tests to diagnose problems. PageSpeed Insights and Search Console can help with different parts of the review. A lab score is not the same as every customer’s experience.

2. Improve Loading

Inspect the largest visible content, image sizes, server response and resources that delay rendering. Prioritise the page’s important content and avoid loading unnecessary media before it is needed.

3. Improve Responsiveness

Check work that keeps the browser busy, including unnecessary scripts and expensive event handlers. Test important interactions such as opening navigation, using filters and submitting forms.

4. Reduce Layout Movement

Reserve space for images and other media. Avoid inserting content above something the visitor is already reading. Check fonts, banners and third-party embeds for unexpected movement.

5. Recheck After Changes

Compare the affected pages before and after the work. Google’s good-experience targets include LCP within 2.5 seconds, INP at or below 200 milliseconds and CLS at or below 0.1, assessed across real visits. Good metrics support usability but do not guarantee a search position or conversion rate.
