Optimize JavaScript Bundle Size
High Impact+5 points estimated
Why It Matters
25KB of unused JavaScript is being loaded unnecessarily, impacting performance.
How to Fix
Enable tree-shaking in your Next.js build configuration. Use dynamic imports with next/dynamic for components not needed on initial load. Analyze your bundle with @next/bundle-analyzer to identify and remove unused dependencies.

What This Score Means
A score of 89 falls in the "Needs Improvement" 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 good overall performance with a score of 89/100, but there's a critical issue blocking optimal loading speeds. The biggest problem is render-blocking CSS and font files that are delaying both First Contentful Paint (2.9s) and Largest Contentful Paint (3.0s) by an estimated 2.5 seconds. The site is loading Google Fonts and CSS files synchronously, which prevents the page from rendering until these resources finish downloading. To significantly improve Core Web Vitals, you should inline critical CSS, preload fonts, and defer non-essential stylesheets to move these resources out of the critical rendering path.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+8 points estimatedWhy It Matters:
CSS files are blocking initial render and delaying LCP by 2.55 seconds.
How to Fix:
In your Next.js app, move critical CSS inline using styled-jsx or CSS-in-JS. Preload the Google Fonts using next/font for automatic optimization. Consider splitting CSS and loading non-critical styles asynchronously using next/dynamic.
Fix Forced Reflow Issues
Medium Impact+3 points estimatedWhy It Matters:
JavaScript is forcing layout recalculations that block the main thread and hurt user interactions.
How to Fix:
Batch DOM reads and writes to avoid layout thrashing. Use CSS transforms instead of changing geometric properties. Implement React's useLayoutEffect sparingly and consider moving calculations to useEffect when possible.
