Loading performance
Measures how long it takes for the largest content element to become visible.
Needs Improvement
2.5s - 4s
👆
First Input Delay (FID)
Interactivity
Measures the time from when a user first interacts with your page to when the browser responds.
Needs Improvement
100ms - 300ms

Speed Optimization Guide: Common Issues & Fixes
Large Unoptimized Images
High Impact30 minutes
Images that haven't been compressed or properly sized can significantly slow down your page.
Quick Fix Steps:
- Compress images using tools like TinyPNG or ImageOptim
- Use next-gen formats (WebP, AVIF) where supported
- Implement responsive images with srcset attributes
- Add lazy loading for below-the-fold images
Excessive CSS/JavaScript
High Impact1-2 hours
Large CSS and JavaScript files block page rendering and increase load times.
Quick Fix Steps:
- Minify CSS and JavaScript files
- Remove unused CSS with tools like PurgeCSS
- Defer non-critical JavaScript loading
- Split code into smaller, manageable chunks
Poor Server Response Time
High ImpactVaries
Slow server responses affect every aspect of your website's performance.
Quick Fix Steps:
- Upgrade hosting plan if needed
- Implement server-side caching
- Use a Content Delivery Network (CDN)
- Optimize database queries and server configuration
No Browser Caching
Medium Impact15 minutes
Without proper caching, users re-download the same resources on every visit.
Quick Fix Steps:
- Set appropriate cache headers for static resources
- Implement browser caching policies
- Use cache-control headers effectively
- Leverage service workers for advanced caching
