Core Web Vitals describe important parts of the user experience: how quickly the main content becomes visible, how promptly the page responds and whether the layout moves unexpectedly.
Good scores support usability, but they are not a substitute for helpful content or a competitive offer. Treat performance as part of product quality rather than a one-time SEO task.
Measure representative pages on real devices, fix oversized media and excessive JavaScript, and prevent layout shifts by reserving space for images, embeds and dynamic components.

Choose the one improvement most likely to reduce friction for a valuable user journey. Measure the result, learn from it and build from there.
