Core Web Vitals are Google’s measures of real-world page experience: how quickly the main content loads, how fast the page responds to interaction, and how stable the layout is while loading.
Work through this checklist and recheck your pages in Search Console as you go.
Loading performance
Optimise the largest element on the page, usually a hero image or heading. Compress and correctly size images, preload critical resources, use fast hosting and enable caching.
Responsiveness
Reduce heavy JavaScript, break up long tasks, defer third-party scripts and remove tools you do not need so the page reacts quickly when visitors tap or click.
Visual stability
Reserve space for images, embeds and ads with explicit dimensions, avoid inserting content above existing content, and load fonts in a way that does not shift the layout.
