Your questions answered
What determines a website's leaderboard position?
Websites are ranked best to worst based on their Core Web Vitals performance. Each website receives a score that combines the performance of three key metrics: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP).
What are Core Web Vitals?
Core Web Vitals (CWV) are a set of metrics used to measure user experience on the web. Each metric measures a different aspect of user experience, focusing on initial content display, visual stability, and responsiveness. For more on CWV, read our guide.
