3. Click Test Now
4. View results when complete

Understanding Results

Good (Green)

• LCP: Under 2.5 seconds
• INP: Under 200 milliseconds
• CLS: Under 0.1

Needs Improvement (Yellow)

• LCP: 2.5 - 4 seconds
• INP: 200 - 500 milliseconds
• CLS: 0.1 - 0.25

Poor (Red)

• LCP: Over 4 seconds
• INP: Over 500 milliseconds
• CLS: Over 0.25

Improving Core Web Vitals

LCP (Loading Speed)

• Optimize images (format, size, lazy loading)
• Reduce server response time
• Preload critical resources
• Use a CDN

INP (Interactivity)

• Minimize JavaScript execution
• Break up long tasks
