Free Web Vitals Comparison Tool - Compare Core Web Vitals Performance

Compare your website's Core Web Vitals performance against competitors using real Chrome User Experience data. Our free tool analyzes Largest Contentful Paint (LCP), Interaction to Next Paint (INP), Cumulative Layout Shift (CLS), and other key performance metrics.

What are Core Web Vitals?

Core Web Vitals are a set of real-world, user-centered metrics that quantify key aspects of the user experience. They measure dimensions of web usability such as load time, interactivity, and the stability of content as it loads.

Largest Contentful Paint (LCP)

LCP measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading.

Interaction to Next Paint (INP)

INP measures interactivity. To provide a good user experience, pages should have an INP of 200 milliseconds or less.

Cumulative Layout Shift (CLS)

CLS measures visual stability. To provide a good user experience, pages should maintain a CLS of 0.1 or less.

Why Web Performance Matters

Website performance directly impacts user experience, search engine rankings, and business metrics. Studies show that:

• 53% of mobile users abandon sites that take longer than 3 seconds to load
• A 1-second delay in page response can result in a 7% reduction in conversions
• Google uses Core Web Vitals as ranking factors in search results
• Faster websites have lower bounce rates and higher engagement
