Speed Checker - Check Website Speed & Core Web Vitals

What are Core Web Vitals?

Core Web Vitals are metrics that measure user experience on websites, used by Google as SEO ranking factors. They include 3 main metrics: LCP (Largest Contentful Paint), FID (First Input Delay), and CLS (Cumulative Layout Shift).

Key Metrics

• LCP (Largest Contentful Paint): Main content load time (< 2.5s is good)
• FID (First Input Delay): First interaction response time (< 100ms is good)
• CLS (Cumulative Layout Shift): Page layout stability (< 0.1 is good)
• FCP (First Contentful Paint): Time to first content display
• TTI (Time to Interactive): Time until page is interactive
• TBT (Total Blocking Time): Total time blocking interactions

How to improve website speed

• Optimize images (compress, use WebP, lazy loading)
• Minify CSS, JavaScript, and HTML
• Use CDN for content delivery
• Enable browser caching and compression
• Reduce number of HTTP requests
• Use fast server response time
• Remove unnecessary JavaScript and CSS
