Professionals of website design in Dubai explain that the Cumulative Layout Shift (CLS) measures the amount of unexpected shifting of visual page content, which can disrupt a user’s experience by causing sudden movements on the page. The ideal CLS score is less than 0.1; anything higher can lead to frustration as users may accidentally click on unintended elements. Reducing CLS involves optimizing images, ads, and dynamic content to load in a stable, predictable way, enhancing both usability and SEO rankings.
