- Real-user data in Search Console matters most
- Images, scripts and layout shifts are the usual culprits
Core Web Vitals are a set of measurements Google uses to judge how pleasant a page feels to use. They are one part of how Google assesses page experience.
Largest Contentful Paint (LCP)
How long it takes for the main content, often a hero image or heading, to appear. Slow servers, large images and render-blocking code make it worse.
Interaction to Next Paint (INP)
How quickly the page responds when someone taps or clicks. Heavy JavaScript is the usual cause of slow responses.
Cumulative Layout Shift (CLS)
How much the page jumps around while loading, such as text moving when an ad or image appears. It is frustrating and causes mis-taps.

Keep perspective
Great content still matters most. But between two similar pages, the faster, smoother one offers a better experience and tends to convert better.
