What is the Google Core Web Vitals report?

The Google Core Web Vitals report uses field data accumulated from the Chrome User Experience report over the previous 3 month period to track and categorize website URLs based on how well (and whether) they are meeting the new Core Web Vitals requirements. 

Why is this report important for search engine optimization?

Core Web Vitals will become a ranking factor in the summer of 2021. The data from this report can be used, for example, to pinpoint groups of URLs and specific URLs that need to be improved in order to help pass the Core Web Vitals assessment.

How does this report work?

The Core Web Vitals report can be found in your Google Search Console.

1. In the left hand rail of the main page nested under “Experience,” click on “Core Web Vitals.”

1. The new page will display charts for mobile and desktop versions of your site displaying URLs over the past 3 month period categorized as “good,” “need improvement,” and “poor.”

1. You can open reports for both in the upper right hand corner of each chart to see more details for each category of URLs: their statuses, issue types, trends, as well as the total number of URLs affected. 

1. Click into any one of the example URLs to see the aggregate scores for Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift.

1. Once you have made fixes to “need improvement” and “poor” URLs, you can click the “validate fix” button. Google will then monitor these URLs for 28 days post-fix to ensure the changes have been made. Sometimes it happens in less time.
