Cumulative Layout Shift (CLS) is a metric for measuring visual stability on a site and helps to quantify how often users experience unexpected layout shifts. CLS measures the sum total of all individual layout shift scores for every unexpected layout shift that occurs during the entire lifespan of the page. A layout shift occurs any time a visible element changes its position from one rendered frame to the next.
CLS affects SEO, and a lower score is better. Sites should strive to have a CLS score of 0.1 or less.
Sulvo-powered ad units eliminate CLS issues by default, no code changes are needed. If you are using a Sticky Mobile Top unit (non-tagless version) placed on your site prior to March 18, 2021, please update the Sticky Mobile tag on your sites with the latest version by clicking "Get Code" on the Inventory section.
