Core Web Vitals are three checks Google uses to see if a page feels usable: how fast the main thing appears, how soon you can tap, and whether the layout jumps while you read. You do not need a 100/100 trophy. You need a site that does not make a customer wait on 4G.

Most customers arrive on a phone. Test there, not only on a fast office Wi-Fi.

The three names, in plain words

  • LCP (Largest Contentful Paint): how long until the big hero or heading shows. Huge slider images are the usual villain.
  • INP (Interaction to Next Paint): how long until a tap feels answered. Heavy popups and chat widgets hurt this.
  • CLS (Cumulative Layout Shift): the page jumping when a banner or font loads late. You tap the wrong button.

What actually moves the needle on a small business site

  1. Compress and size images. Do not upload a 5000px photo for a 400px card.
  2. One hero, not five autoplay videos.
  3. Give images width and height so the page does not jump.
  4. Be careful with extra scripts: three chat tools, four pixels, a popup on first visit.
  5. Use a cache plugin or host cache after a backup. Do not stack three cache plugins.

Ignore the vanity score

A 92 vs 96 does not grow revenue. A 4-second wait on the quote form does. Fix the pages that take money: home, service, contact, checkout.
