Сumulative layout shift

In the ever-evolving world of web performance, user experience is more important than ever. Google’s Core Web Vitals are a crucial factor in determining how well a website performs in terms of Google Page Experience core web vitals. Among the key metrics that Google uses to measure UX, Cumulative Layout Shift stands out as a critical one. This metric evaluates how stable your page layout is, ensuring users aren’t frustrated by unexpected movements during page load. If you want your site to rank higher and offer an exceptional experience, understanding what is a CLS, how to test it, and how to improve it is vital. This cumulative layout shift guide will take you through everything you need to know about CLS and how to optimize it to ensure better user satisfaction and SEO results. What is Cumulative Layout Shift? Cumulative Layout Shift is a metric that measures the cumulative score of unexpected shifts in the layout of a webpage while it's loading. Essentially, if the content on your webpage moves unexpectedly after the page starts to load (like images or buttons shifting positions), it causes a poor experience for the user, leading to CLS. Why is CLS Important? Google Ranking Factor: CLS is one of the key elements in the Core Web Vitals, which are used by Google to assess the Google Page Experience core web vitals. A poor CLS can harm your rankings. User Experience: Users expect pages to load quickly and remain stable. Any unexpected content layout shift can frustrate users and cause them to abandon the page. SEO Impact: Core Web Vitals SEO optimization, which includes improving your CLS, directly impacts your site's search engine rankings. Understanding Core Web Vitals: The Big Picture To fully understand the importance of CLS, you need to grasp how it fits into the larger picture of Core Web Vitals. These three metrics—LCP (Largest Contentful Paint element), FID (First Input Delay), and CLS—play a significant role in determining user satisfaction. Core Web Vitals Breakdown: 📍 Largest Contentful Paint element (LCP): Measures the time it takes for the largest visible element on the page to load. 📍 First Input Delay (FID): Measures the time between the user’s first interaction with the page and the page’s response. 📍 Cumulative Layout Shift: Measures how much the layout shifts during page load.

What is the Meaning of CLS in Core Web Vitals? Cumulative layout shift meaning is simple: it’s a measure of unexpected shifts in the layout of a webpage during load. When a page loads and elements move around unexpectedly—like text jumping, buttons shifting, or images appearing late—it results in a poor CLS score. This can create a confusing and frustrating experience for users. How to Solve the Issue About Cumulative Layout Shift? Fixing CLS issues requires a combination of best practices for Core Web Vitals optimization. Here are a few tips to help reduce layout shifts: 🛠️ Reserve Space for Elements: Make sure that elements like ads, images, and videos have space reserved in the layout. 🛠️ Avoid Late Fonts and Images: Ensure that fonts and images load properly, with defined sizes and placeholders to avoid content jumps. 🛠️ Improve Rendering Performance: Use techniques like lazy loading for images to make sure that elements load in the correct order.

Sites with higher inp Core Web Vitals scores are more likely to rank higher on Google, giving you an edge over competitors.

Users will stay longer and engage more if they don’t experience annoying shifts in layout as the page loads.
