Site Speed and Core Web Vitals

Core Web Vitals are a set of measurements Google uses to judge how good a page feels to use. The three main ones are Largest Contentful Paint (LCP), which measures how long the main content takes to load; Interaction to Next Paint (INP), which measures how quickly the page responds to clicks and taps; and Cumulative Layout Shift (CLS), which measures whether elements unexpectedly jump around while loading.

A slow or jumpy page frustrates visitors, who often leave before it finishes loading. That behavior signals to search engines that the page may be a poor result, even if the content itself is excellent.

Common causes of slow pages include oversized, unoptimized images, too many heavy scripts loading at once, and slow web hosting. Compressing images and removing unused scripts are often the fastest wins.
