Core Web Vitals
Core Web Vitals are three values Google uses to measure how fast a page loads, how quickly it responds and how stable it looks. Together they show how comfortable a page is to use.
What are Core Web Vitals?
Core Web Vitals are three measurements Google uses for page experience. LCP measures how long the main content takes to appear. INP measures how quickly the page reacts when you tap or click. CLS measures whether things jump around while the page loads.
Here is an everyday case. You open a site on your phone and are about to tap a link when an image loads and pushes the text down. You tap the wrong thing. That is a poor CLS score. Reserving space for images fixes it.
Why does it matter?
Slow, jumpy pages lose visitors, and Google uses these values as part of how it assesses page experience. You can check your own site with Google's free PageSpeed Insights tool. We keep these values in mind from the start, as described on our web design page. We walk through the fixes step by step in site speed and Core Web Vitals.
Frequently asked questions
How do I measure my Core Web Vitals?
Enter your address into Google's free PageSpeed Insights tool. It shows LCP, INP and CLS based on real user data. The Core Web Vitals report in Google Search Console lists which pages have problems.
What are good Core Web Vitals scores?
By Google's thresholds, LCP should be under 2.5 seconds, INP under 200 milliseconds and CLS under 0.1. These should hold for most visits. Thresholds can change, so check the current values on web.dev.
Do Core Web Vitals affect rankings?
Yes, but they are not decisive on their own. Google uses them as part of how it assesses page experience. Content that answers the question still matters more.
What usually hurts Core Web Vitals?
Large uncompressed images, heavy web fonts and many third-party scripts are the usual causes. Images and ad slots without set dimensions make the page shift.
