I have no idea what you're talking about. What "core web vitals?" What is a "common layout shift?" What errors do you see? Please *show* them, since none of us is sitting in front of your computer.

CLS is stands for cumulative layout shift. If you have a lengthy page then CLS is natural because in page which have much content we use div and p tag images etc many times.

To remove the CLs issue first you need to check the page structure and hierarchy of nesting tags and, also check the both side  (left and right) edges of the page that any content is not out of the margin line or inside of the margin line.

Core Web Vitals are a set of specific factors that Google considers important in a webpage’s overall user experience. Core Web Vitals are made up of three specific page speed and user interaction measurements: 

  • Largest Contentful Paint
  • First input Delay
  • Cumulative Layout Shift

It is not mentioned in the link above, but server speed, and how long it takes to deliver files, plays a big part on this measurement.

The Core Web Vitals report shows URL performance grouped by status (Poor, Need improvement, Good), metric type (CLS, FID, LCP), and URL group (groups of similar web pages). The report is based on three metrics as measured by actual user data: LCP, FID, and CLS.
