What Are Core Web Vitals?
Core Web Vitals are a set of specific metrics Google uses to measure real-world user experience on a web page — focusing on loading speed, interactivity, and visual stability.
Why it matters
Core Web Vitals are part of Google’s page experience signals and can influence rankings, especially when competing pages are otherwise similar in quality. More importantly, they measure how the page actually feels to users — slow, janky pages drive visitors away and hurt conversions. The three metrics are LCP (Largest Contentful Paint, loading), INP (Interaction to Next Paint, responsiveness), and CLS (Cumulative Layout Shift, stability).
Example
A page where the layout jumps around as images load has a poor CLS score — frustrating users who tap the wrong button. Reserving space for images and ads fixes it.
