I have been working on my website’s SEO for months, but my rankings are stalled. My PageSpeed Insights report shows poor scores for LCP and CLS. Can someone explain how heavily Google weighs these Core Web Vitals in 2024 and what specific technical steps I should take to fix layout shifts?

Core Web Vitals are a critical part of Google's Page Experience signals. While great content is still king, a poor LCP (Largest Contentful Paint) or high CLS (Cumulative Layout Shift) can act as a tie-breaker between you and a competitor. To fix CLS, you must ensure all images and ad elements have defined height and width attributes in the HTML. This prevents the page content from "jumping" as assets load. In my experience optimizing enterprise sites in 2023, moving to a better CDN and lazy-loading non-critical CSS provided the biggest boost to our mobile rankings.
That makes sense, but does improving these metrics actually provide a direct ranking lift, or is it more about reducing the bounce rate of visitors who get frustrated by slow loading?
Don't forget mobile-first indexing. Always test your Core Web Vitals on a 4G connection simulation, not just your fast office Wi-Fi, to see the real impact.
Great point, Jessica. Most developers forget that Google crawls primarily as a mobile user, so desktop scores are often misleading for SEO purposes.
Michael, it’s actually both. Google confirmed these are ranking factors, but the indirect benefit is massive too. If your CLS is high, users accidentally click the wrong buttons and leave immediately. This sends a "pogo-sticking" signal to Google that your result didn't satisfy the user intent. By fixing the technical layout shifts, you improve the dwell time, which reinforces your authority in the eyes of the algorithm.
