Core Web Vitals [CWV]

Core Web Vitals
« Back to Glossary Index

Core Web Vitals (CWV) are a series of metrics that measure a website’s loading, interactivity, visual stability, and more. Google released these intending to help assess whether your website provides a good user experience.

We can use Page Speed Insights to measure CWV performance and Google Search Console to see how many pages on our websites do not pass the Core Web Vitals assessment.

Measuring CWV

While the CWV includes other metrics, such as mobile-friendliness, safe browsing, and intrusive interstitials, the initial metrics of focus were Largest Contentful Paint (LCP), First Input Delay (FID), which has since been replaced by Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS).

These factors are measured on real-world usage (known as field data) and simulated conditions that a user may encounter (known as lab data).

Even though CWV is not a strict ranking factor, it helps Google assess the quality and user experience of the page and, therefore, should not be ignored.
