Core Web Vitals are Google’s ranking factors that measure user experience. According to Google’s PageSpeed Insights, websites with good Core Web Vitals rank higher in search results.
Here is how to optimize your website for Core Web Vitals and improve your Google rankings.
What Are Core Web Vitals?
- LCP (Largest Contentful Paint): How fast the main content loads. Target: under 2.5 seconds.
- FID (First Input Delay): How fast the page responds to user interactions. Target: under 100 milliseconds.
- CLS (Cumulative Layout Shift): How much the page layout shifts unexpectedly. Target: under 0.1.
How to Optimize Each Metric
LCP Optimization
- Optimize images (use WebP format, compress files)
- Use a Content Delivery Network (CDN)
- Enable browser caching
- Minimize CSS and JavaScript files
- Use fast hosting (cloud hosting recommended)
FID Optimization
- Minimize JavaScript execution time
- Break up long tasks
- Use web workers for heavy computations
- Defer non-critical JavaScript
CLS Optimization
- Set explicit width and height for images and videos
- Reserve space for dynamic content (ads, embeds)
- Avoid inserting content above existing content
- Use CSS transform animations instead of layout-changing animations
