Core Web Vitals (مقاييس الويب الأساسية)
Core Web Vitals are Google's three key page-experience metrics: LCP (loading speed — largest content under 2.5s), INP (interactivity — responses under 200ms), and CLS (visual stability — shifts under 0.1). They measure real user experience and influence rankings and conversions.

In detail
Core Web Vitals turn user experience into measurable signals. LCP measures how fast the main content becomes visible — slow images, render-blocking scripts, and distant servers hurt it. INP replaced First Input Delay in 2024 and measures responsiveness across every interaction; heavy JavaScript and long tasks degrade it. CLS tracks unexpected layout shifts caused by images without dimensions or injected content. Scores come from real-user field data in Chrome, not lab tests alone. These metrics are ranking tie-breakers and strongly affect bounce rates and conversions — every 100ms of delay costs measurable revenue. Optimization combines fast hosting, CDNs, image optimization, code splitting, and minimal third-party scripts.
Practical example
Moving images to a CDN and lazy-loading below-the-fold content cut LCP from 4.1s to 1.8s.
Frequently asked questions
What are good Core Web Vitals scores?
LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1, measured on real user data.
Do Core Web Vitals affect rankings?
They are a page-experience signal and tie-breaker between similarly relevant pages, and they strongly impact conversions.
