What is cumulative layout shift CLS?
CLS is a measure of the largest burst of layout shift scores for every unexpected layout shift that occurs during the entire lifespan of a page. A layout shift occurs any time a visible element changes its position from one rendered frame to the next.
Does CLS affect performance?
Cumulative Layout Shift is a ranking factor in Google as it affects the website's performance and user experience. It is one of the Core Web Vitals metrics, and Google can penalize a site that does not meet its standard. A poor CLS score indicates that a website is unreliable, which can cause visitors to leave faster.
