LCP, Largest Contentful Paint, is one of the new Core Web Vitals, which include FID (First Input Delay) and CLS (Cumulative Layout Shift). The Core Web Vitals are part of Google’s new ranking factor: Page Experience that will be implemented in 2021.
The Core Web Vitals measure the speed, interactivity and stability of a web page.
LCP is a measure of how quickly the main content or element of a web page renders on a device. If your website is set up with a Google Search Console profile you can find out what Googlebot thinks of your LCP, as well as the FID and CLS in the Core Web Vitals report.
If your LCP is over 4 seconds, it will be reported as a Poor URL in the Report. There is a Report for Mobile and for Desktop.
If your LCP is poor like in the above GSC report then you’ll want to fix it before 2021 if not before.
Google will give you sample URLs that are representative of a page archetype with the issue. So your next step is to evaluate the page’s LCP to see if can be improved. To do that you have to first identify the HTML element that is the LCP. You can use Chrome Dev Tools to do this.
Using the Performance tab we can run a recording of the web page’s render that will show us the LCP.
Now you can locate the HTML element that is being measured by the LCP:
