Optimize Images for Modern Formats
High Impact+12 points estimated
Why It Matters
Large unoptimized images are causing 1.9MB of wasted bandwidth and delaying LCP by 750ms.
How to Fix
Convert the 3.4MB avatar image to WebP/AVIF format which will reduce size by 40-60%. Implement responsive images with srcset for different screen sizes. Configure your Supabase storage to serve modern image formats automatically or use a CDN like Cloudinary.

AI Performance Analysis
This website has good performance with a score of 83/100, but there are several opportunities for improvement. The biggest issue is extremely large image files totaling over 5MB, with one image alone being 3.4MB and causing significant layout shifts as the page loads. Converting these images to modern formats like WebP could save nearly 2MB of data and improve loading times by 750 milliseconds. Additionally, images lack explicit width and height dimensions, which is causing layout shifts that hurt the user experience as elements move around while the page loads.

High Impact+10 points estimatedWhy It Matters:
Unsized images are causing a CLS score of 0.252, significantly hurting user experience and rankings.
How to Fix:
Add explicit width and height attributes to all image elements, especially the logo and category icons. Use CSS aspect-ratio property to maintain proper dimensions. Reserve space for dynamically loaded content with placeholder containers of fixed dimensions.
Implement Efficient Caching Strategy
Medium Impact+8 points estimatedWhy It Matters:
Short 1-hour cache lifetime for static assets wastes 3.6MB of repeat downloads for returning visitors.
How to Fix:
Configure your Supabase storage bucket to serve images with longer cache headers (1 year for static assets). Add cache-control headers for CSS and JavaScript files. Implement versioning or fingerprinting for cache busting when assets change.
