What are Core Web Vitals?
Core Web Vitals are three new metrics Google uses to measure the page experience of your visitors. From mid-June this year Google will use these metrics as a ranking signal in mobile search. All things being equal, pages with better Core Web Vitals scores will outrank those with poorer scores.
The three metrics are related to speed (LCP), responsiveness (FID) and visual stability (CLS), and for each metric your pages will receive a label of either Good, Needs Improvement, or Poor. All three must be Good in order to benefit from a potential ranking boost.
A better page experience has always helped your visitors. Now it will help your SEO.
Largest Contentful Paint
Ever wondered if a page is actually loading?
Largest Contentful Paint (LCP) is the time it takes for your largest piece of content to become visible on the page – whether that’s text, an image, a banner, or a video.
To get a score of ‘Good’ for LCP, the largest visible piece of content needs to have fully loaded within 2.5 seconds.
First Input Delay
Ever clicked a button and waited for the page to catch up?
First Input Delay (FID) is the reaction time of your page, after a visitor tries to do something – whether that’s tapping a button, a link, or typing in a text box.
To get a score of ‘Good’ for FID, your pages should react to user events within 100 milliseconds.
Cumulative Layout Shift
Ever seen a page shuffle round as it loads?
Cumulative Layout Shift (CLS) measures the visual stability of a page as it renders on screen. It calculates the distance that all items on the page move – often that’s because of images, pop-ups, or ad banners.
To get a score of ‘Good’ for CLS, pages should maintain a CLS score of 0.1 or less.
