Core Web Vitals Checker
Analyze LCP, INP, and CLS instantly to ensure your website passes Google's Core Web Vitals assessment.
Why Core Web Vitals Matter
Google uses Core Web Vitals as a significant ranking factor. By optimizing your Largest Contentful Paint (LCP), Interaction to Next Paint (INP) / First Input Delay (FID), and Cumulative Layout Shift (CLS), you can drastically improve your search engine rankings and user retention rates.
What Our Checker Tests
- Largest Contentful Paint (LCP): Measures how long it takes for the largest visual element on the screen to load.
- Interaction to Next Paint (INP): Measures a page's overall responsiveness to user interactions.
- Cumulative Layout Shift (CLS): Measures the visual stability of a page and prevents annoying unexpected shifts.
By consistently monitoring these metrics with Pathlight's Core Web Vitals Checker, you can quickly identify bottlenecks and optimize your front-end architecture.
