Core Web Vitals & SEO Checker

Core Web Vitals are three key metrics Google uses to measure user experience on your website. Largest Contentful Paint (LCP) measures how quickly your main content loads. Interaction to Next Paint (INP) measures how responsive your page is to user interactions like clicks and taps. Cumulative Layout Shift (CLS) measures how much your page layout shifts unexpectedly during loading. These metrics directly impact your Google search rankings and should be optimized for better SEO performance.

A good Largest Contentful Paint (LCP) score is 2.5 seconds or less. If your LCP is between 2.5s and 4.0s, it needs improvement. Anything over 4.0s is considered poor and should be fixed immediately. To improve LCP, optimize images, use a Content Delivery Network (CDN), reduce server response time, and eliminate render-blocking resources.

A good Cumulative Layout Shift (CLS) score is 0.1 or less. CLS measures how much your page layout shifts unexpectedly during loading. A score between 0.1 and 0.25 needs improvement, and anything above 0.25 is poor. To fix CLS, always set image and video dimensions, avoid inserting content above existing content, and use CSS transform animations instead of layout-triggering properties.

A good Interaction to Next Paint (INP) score is 200 milliseconds or less. INP measures how quickly your page responds to user interactions. Scores between 200ms and 500ms need improvement, and above 500ms is considered poor. To improve INP, reduce JavaScript execution time, break up long tasks, and use web workers for heavy computations.
