Core Web Vitals

Core Web Vitals are a set of standardized metrics from Google that help developers and site owners quantify the "health" of their site’s user experience. These metrics specifically target three pillars: Largest Contentful Paint (LCP) for loading performance, First Input Delay (FID) – or Interaction to Next Paint (INP) – for responsiveness, and Cumulative Layout Shift (CLS) for visual stability. Together, they provide a data-driven look at whether a site feels fast and stable to a real human user, rather than just how fast it appears to a laboratory test.

From an SEO perspective, mastering Core Web Vitals is one of the most effective ways to improve rankings in a competitive market. Because Google uses these signals to determine page experience, a high score can be the deciding factor in who wins the top spot in search results. Beyond SEO, improving these vitals leads to tangible business results: faster, more stable sites consistently see lower bounce rates, higher conversion rates, and increased customer satisfaction.
