Core Web Vitals are a set of performance metrics that Google has identified as being important for a good user experience on the web. They include:
- Largest Contentful Paint (LCP): This measures the time it takes for the main content of a webpage to load and become visible to the user.
- First Input Delay (FID): This measures the time it takes for a webpage to become interactive, based on the user’s input.
- Cumulative Layout Shift (CLS): This measures the stability of a webpage, based on the amount of unexpected layout shifts that occur while the page is loading.
In Google Search Console, the Core Web Vitals report shows you the performance of your website based on these metrics. It provides information on the median value of each metric for your website, as well as the percentage of pages on your site that meet the recommended thresholds for each metric. By monitoring these metrics, you can get a sense of the overall performance of your website and identify any areas that may need improvement.
Google has stated that it will begin using these metrics as ranking signals in its search algorithm in 2021, so improving the performance of your website based on these metrics can help improve your site’s ranking in search results.
