Understanding Core Web Vitals and Google search results
Core Web Vitals is a set of metrics that measure real-world user experience for loading performance, interactivity, and visual stability of the page. We highly recommend site owners achieve good Core Web Vitals for success with Search and to ensure a great user experience generally. This, along with other page experience aspects, aligns with what our core ranking systems seek to reward. Learn more in Understanding page experience in Google Search results.
Core Web Vitals metrics
- Largest Contentful Paint (LCP): Measures loading performance. To provide a good user experience, strive to have LCP occur within the first 2.5 seconds of the page starting to load.
- First Input Delay (FID): Measures interactivity. To provide a good user experience, strive to have an FID of less than 100 milliseconds. Starting March 2024, Interaction to Next Paint (INP) will replace FID as a Core Web Vital.
- Cumulative Layout Shift (CLS): Measures visual stability. To provide a good user experience, strive to have a CLS score of less than 0.1.
