Implement Proper Browser Caching

Medium Impact+8 points estimated

Why It Matters

Poor cache policies force re-downloading 855 KiB on repeat visits, slowing return user experience.

How to Fix

Configure next.config.js headers for static assets with 1-year cache lifetime. Set CDN cache headers for images to 31536000 seconds. Use Next.js automatic static optimization and enable immutable cache headers for _next/static files.

What This Score Means

A score of 49 falls in the "Poor" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.

This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.

Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis

This Next.js/React site has poor performance with a score of 49/100 and extremely slow loading times. The biggest problem is oversized, unoptimized images that are causing an 18.6-second Largest Contentful Paint - one event thumbnail alone is wasting 738KB by using PNG instead of WebP format and serving images much larger than their display size. The site is also loading 559KB of unused JavaScript and 50KB of unused CSS, while poor caching policies are forcing users to re-download large assets on every visit. Optimizing images to modern formats like WebP, implementing proper responsive images, and removing unused code could dramatically improve the score by 30+ points and reduce load times by over 10 seconds.

Other Optimization Recommendations

Optimize Image Delivery and Format

High Impact+25 points estimated

Why It Matters:

Images waste 1,484 KiB and severely impact LCP with the largest image being 18x larger than needed.

How to Fix:

Implement Next.js Image component with responsive sizing and WebP/AVIF formats. Use next/image with proper width/height props and sizes attribute. Configure next.config.js with image optimization domains and formats: ['image/webp', 'image/avif'].

Reduce Unused JavaScript Bundles

High Impact+20 points estimated

Why It Matters:

559 KiB of unused JavaScript delays LCP by 2.8 seconds and blocks main thread execution.

How to Fix:

Enable Next.js tree shaking and dynamic imports for large components. Use next/dynamic for code splitting heavy libraries. Analyze bundle with @next/bundle-analyzer to identify and remove unused dependencies. Move Google Analytics to _app.js with proper async loading.
