Google measures how your website feels to real visitors using three numbers called Core Web Vitals. They affect rankings a little and sales a lot, because slow and jumpy pages make people leave.

LCP: how quickly the main content appears

Largest Contentful Paint measures how long it takes for the biggest thing on the screen, usually a heading or a large image, to show up. Aim for under 2.5 seconds on a phone.

Usual fixes: smaller, modern image formats, a faster server, fewer scripts in the way, and making sure the main image loads first.

INP: how quickly the page reacts

Interaction to Next Paint measures the delay between tapping something, like a menu or a button, and the page responding. Aim for under 200 milliseconds.

Usual fixes: removing heavy scripts, chat widgets and trackers you do not need, and loading the rest after the page is ready.

CLS: how much the page jumps around

Cumulative Layout Shift measures how much content moves while the page loads. You have felt it when you try to tap a link and an image or banner pushes it away. Aim for under 0.1.

Usual fixes: giving every image a fixed size, reserving space for banners and ads, and loading fonts carefully.

How to check your own site

  1. Open PageSpeed Insights and enter your address.
  2. Look at the top section, which uses data from real visitors if Google has enough.
  3. Check the Core Web Vitals report in Google Search Console to see which groups of pages fail.

What matters most

Do not chase a perfect score for its own sake. Aim for passing numbers on your most important pages, especially the ones your ads and search traffic land on.

If your site is failing, our website speed service finds and fixes the causes.
