Cumulative Layout Shift (CLS) is a user experience metric that measures the visual stability of a webpage by tracking unexpected layout shifts during page load. A low CLS score indicates that the content remains stable, ensuring that users do not experience disruptions that could lead to accidental clicks or a poor browsing experience. This metric is a key component of Google’s Core Web Vitals and plays a significant role in overall site performance and SEO.
High CLS scores can frustrate users, leading to increased bounce rates and decreased engagement, as elements on the page move unexpectedly during loading. Addressing CLS involves optimizing images, fonts, and dynamic content to prevent shifts in layout. Ensuring that the visual structure of a page remains consistent as it loads is critical for delivering a smooth, user-friendly experience.
Improving CLS is an ongoing process that requires regular performance monitoring and technical adjustments. By prioritizing visual stability, businesses not only enhance user satisfaction but also improve their search engine rankings. Ultimately, a low cumulative layout shift contributes to a seamless browsing experience, which is vital for maintaining high levels of user engagement and conversion rates.
