Core Web Vitals Checker
Measure your page's performance against Google's key metrics: LCP, INP, and CLS. Ensure an excellent user experience and search engine ranking potential.
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 visual stability.**
LCP (Largest Contentful Paint)
Measures **loading performance**. Marks the time when the largest text or image block is rendered.
Goal: 2.5 seconds or less.
INP (Interaction to Next Paint)
Measures **interactivity**. Assesses the latency of all click, tap, and keyboard interactions made by users.
Goal: 200 milliseconds or less.
*(This metric is replacing FID.)*CLS (Cumulative Layout Shift)
Measures **visual stability**. Quantifies the unexpected shifting of page content.
Goal: 0.1 or less.
