As with Google’s previous updates, any offered website’s rankings may knowledge a drop, go up or remain the similar. 

Google furnished information about their main updates here. However, we’ll present you with a checklist you can use to enhance for the three big metrics underneath this update.

Major Content material Paint (LCP)

You can use Search Console to check your CLS rating. A rating of <0.1 is considered good, 0.1 to 0.25 will need improvement, and more than 0.25 is considered poor. 

Aim for a score of 0.1 or less to ace page experience.
