Core Web Vitals — what they are and why they affect ranking
Three specific measurements now directly influence where you appear in Google search results. Most business owners have never heard of them. Their competitors have.
Core Web Vitals is a set of three specific measurements Google uses to assess the real-world experience of visiting your website. Not theory. What it actually feels like to load your page on a real phone with a real internet connection.
Largest Contentful Paint (LCP) — loading
LCP measures how long it takes for the largest visible element on your page to fully load. Google wants this within 2.5 seconds. Anything over 4 seconds is a fail.
Interaction to Next Paint (INP) — interactivity
INP measures how quickly your site responds when a user does something. Target: under 200 milliseconds. INP issues usually come from too much JavaScript executing on page load.
Cumulative Layout Shift (CLS) — visual stability
CLS measures how much the page jumps around while loading. Google wants a CLS score below 0.1. Common causes: images without defined dimensions, web fonts loading and swapping, banner ads pushing content down.
Core Web Vitals is Google telling you clearly: fast, stable, responsive websites rank better.
The fixes that make the biggest difference
- Convert your images to WebP format — typically 25–35% smaller than JPEG/PNG.
- Specify width and height on all images so the browser reserves space.
- Reduce third-party scripts — audit chat widgets, pixels, marketing tools.
- Upgrade your hosting from cheap shared hosting to managed cloud.
- Enable caching for returning visitors and common assets.
