# Core Web Vitals explained for small business owners

Core Web Vitals are Google's measures of how fast a page loads, how quickly it responds and how stable it is. Here is what they mean in practice.

By [Matthew Coleman](/about), MCC Solutions

**Quick answer.** Core Web Vitals are Google's measures of load speed, responsiveness and stability. Largest Contentful Paint should be 2.5 seconds or less, Interaction to Next Paint 200 milliseconds or less, and Cumulative Layout Shift should be low so the page does not jump around while loading.

## The three measures

Largest Contentful Paint (LCP) is how long the main content takes to appear. Google considers 2.5 seconds or less good. Interaction to Next Paint (INP) is how quickly the page responds when someone taps; 200 milliseconds or less is considered good. Cumulative Layout Shift (CLS) is how much things jump around while loading; 0.1 or less is good. Check Google's current thresholds.

## How to check

Run your page through PageSpeed Insights. It shows lab tests and, when enough data exists, real-user data. The Core Web Vitals report in Search Console groups your pages.

## Common causes of slow pages

Oversized images. Fonts and CSS that block rendering. Too many scripts from plug-ins, chat widgets and trackers. Slow hosting without caching or compression.

## Common fixes

Compress and resize images, using modern formats. Load fonts efficiently. Defer scripts you do not need immediately. Turn on caching and compression. Set image sizes so the page does not jump.

## Keep it in perspective

Speed matters mostly because visitors leave slow sites. A good score will not outrank better content, but a bad one can cost you customers.

## Common questions

**Do I need a perfect score?**

No. Aim for a fast real-world experience on a phone.

**Why does my score change each time?**

Lab tests vary with network and server conditions. Look at trends and real-user data.

This guide is general information. Search engines change how they work and their guidelines; check Google's current documentation for your situation. Nobody can guarantee a ranking.
