Google recently announced a new algorithm update that will roll out in 2021 that ranks websites on the quality of a user’s experience on a web page. Didn’t they always do this? The new “Core Web Vitals” and it can be broken down into these components below.
Google suggests Best Practice should be where a website Largest Contentful Paint (LCP) should occur within 2.5 seconds when a webpage starts loading. First Input Delay (FID) measures interactivity and pages should have a FID of less than 100 milliseconds while Cumulative Layout Shift (ClS) measures visual stability and pages should maintain a CLS of less than 0.1.
The focus is on speed again and content as always. Interesting, there is a new focus on the stability of content as the page loads. SO what does this mean? So when we found this CLS issue inside Google Search Console for one of our clients across 46 URLs, we followed all the links to ‘Learn More’ yet the links just take you back to https://developers.google.com/speed/pagespeed/insights/ which then doesn’t reference Core Web Vitals. NICE!
