Fix Layout Shifts from Images
Medium Impact+8 points estimated
Why It Matters
Unsized images cause a 0.352 CLS score, creating jarring content jumps that hurt user experience and Core Web Vitals.
How to Fix
Add explicit width and height attributes to all img elements, especially the app store badges in the footer. Use Next.js Image component with proper sizing for responsive images. Reserve space for dynamic content with CSS aspect-ratio or min-height properties.

What This Score Means
A score of 18 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 site has severe performance issues with a critically low score of 18/100. The biggest problem is excessive JavaScript blocking the main thread for over 40 seconds, causing an extremely slow Time to Interactive of 48.6 seconds and poor user experience. The site is loading nearly 500KB of unused JavaScript and has render-blocking CSS that delays content loading by over 1 second. Removing unused code, optimizing JavaScript execution, and addressing the layout shifts from unsized images could dramatically improve performance and make the site usable for visitors.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+25 points estimatedWhy It Matters:
CSS files are blocking page render for 1.1 seconds, severely delaying LCP and FCP by preventing the page from displaying content.
How to Fix:
Use Next.js dynamic imports to split CSS by components. Inline critical CSS for above-the-fold content using @next/bundle-analyzer. Move non-critical CSS (like the 29KB unused CSS) to load asynchronously with media='print' then switch to 'all' on load.
Remove Unused JavaScript Code
High Impact+30 points estimatedWhy It Matters:
470 KiB of unused JavaScript is blocking the main thread for 25+ seconds and delaying LCP by 1.7 seconds.
How to Fix:
Use Next.js code splitting with dynamic imports for components not needed on initial load. Configure webpack-bundle-analyzer to identify unused code. Remove legacy polyfills since modern browsers support ES6+ features, saving 40 KiB immediately.
