Be sure to check Core Web Vitals for both the desktop and mobile versions of your website pages. The result for CLS, LCP & FID metrics may be 'good', 'needs improvement' or 'poor'.
As for LCP - an individual page’s content must load in less than 2.5 seconds. An FID of 100 milliseconds and lower is perfect. A good CLS will be below 0.1.
Your pages need to be within the green measurements for all three Core Web Vitals to get the full benefit of any ranking boost (plus great content, of course!)
