What are Core Web Vitals?
Core Web Vitals are a set of specific metrics Google uses to measure a webpage's user experience. They focus on three main areas: loading performance (LCP), interactivity (FID/INP), and visual stability (CLS). Meeting these benchmarks is a confirmed ranking factor for both mobile and desktop search.
Core Web Vitals represent Google's effort to quantify the 'feel' of a website. It is no longer enough to just have great content; the technical delivery must also be smooth. The three pillars are: 1. Largest Contentful Paint (LCP), which measures how fast the main content loads; 2. First Input Delay (FID), recently being replaced by Interaction to Next Paint (INP), which measures how quickly the page responds to a user's first click; and 3. Cumulative Layout Shift (CLS), which measures how much the page elements 'jump around' while loading. If your site performs poorly in these areas—for example, if a button moves just as a user is about to click it—Google views this as a poor experience. Sites that pass the Core Web Vitals thresholds often see a slight ranking boost, but more importantly, they see higher conversion rates and lower bounce rates because the site is simply more pleasant to use. Optimizing these requires a mix of server-side improvements, image compression, and efficient coding practices.
