Synonyms: Web performance metrics User experience factors
CWV stands for Core Web Vitals, a set of specific metrics introduced by Google to measure and improve user experience on websites. These vitals focus on three key aspects of performance: loading speed, interactivity, and visual stability. Google uses CWV as part of its ranking factors, meaning websites that perform well in these areas can potentially rank higher in search results.
The three Core Web Vitals are:
- Largest Contentful Paint (LCP): Measures how quickly the largest element on a webpage loads, with an optimal target of under 2.5 seconds.
- First Input Delay (FID): Tracks the time it takes for a page to respond to a user’s first interaction, ideally less than 100 milliseconds.
- Cumulative Layout Shift (CLS): Assesses visual stability by measuring unexpected layout shifts during page loading. A good CLS score is below 0.1.
Core Web Vitals aim to quantify user experience, helping website owners and developers optimize performance for better engagement and satisfaction. By focusing on these metrics, you ensure that your site is fast, responsive, and visually stable, all of which contribute to a more user-friendly web experience and improved SEO.
