Fix Font-Induced Layout Shifts
High Impact+25 points estimated
Why It Matters
Material Symbols font loading causes significant layout shifts (CLS: 0.352), severely impacting user experience.
How to Fix
Add font-display: swap to your Google Fonts import. Preload the Material Symbols font using <link rel='preload' as='font'> in your Next.js _document.js. Use font metric overrides or size-adjust CSS to minimize layout shifts during font swaps.

What This Score Means
A score of 9 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 score of only 9/100. The biggest problem is excessive JavaScript execution taking over 41 seconds of main thread work, causing extremely slow loading times - your page takes 49 seconds to become interactive and 14 seconds for the largest content to appear. The site is loading 470KB of unused JavaScript and experiencing significant layout shifts when web fonts load, which creates a jarring user experience. Reducing unused JavaScript, optimizing font loading, and implementing proper caching could dramatically improve performance by 20+ seconds and provide a much better user experience.
Other Optimization Recommendations
Reduce Unused JavaScript Payload
High Impact+18 points estimatedWhy It Matters:
470 KiB of unused JavaScript delays LCP by 2.4 seconds and blocks user interactions.
How to Fix:
Use Next.js dynamic imports with code splitting for non-critical components. Remove or lazy-load Google Analytics until user interaction. Audit your bundle with next-bundle-analyzer to identify unnecessary polyfills and dependencies that can be eliminated.
Eliminate Render-Blocking CSS
High Impact+12 points estimatedWhy It Matters:
CSS files block initial page render, delaying both FCP and LCP by 900ms.
How to Fix:
Inline critical CSS for above-the-fold content in your Next.js pages. Move non-critical CSS to load asynchronously using next/dynamic or loadCSS library. Consider extracting unused CSS (28 KiB savings identified) from your stylesheets.
