Google introduced Core Web Vitals to measure a web page's overall experience beyond its content value. This new SEO signal assesses how users perceive the interaction with a webpage, focusing on three key metrics: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and First Input Delay (FID). These vitals help search engines understand the user's perception of a website's performance, which affects its overall ranking. Google bases Core Web Vitals on real user metrics, making it essential to consider device and location when optimizing for this signal. To evaluate the impact of Core Web Vitals on SEO, developers can use various tools and strategies, including Lighthouse, PageSpeed Insights, Treo's site speed tool, and their own real user monitoring platforms. By improving Core Web Vitals, businesses can increase conversions, click-through rate, and revenue uplift, as well as decrease bounce rates and cost per acquisition.
