Reduce JavaScript Bundle Size
High Impact+12 points estimated
Why It Matters
1.3MB of unused JavaScript blocks the main thread for 1.7 seconds, preventing user interactions.
How to Fix
Enable Next.js dynamic imports for heavy components that aren't immediately visible. Split vendor chunks more aggressively using webpack bundle analyzer to identify large dependencies. Implement code splitting at the route level and lazy load non-critical features using React.lazy().

AI Performance Analysis
This Next.js site has poor performance with a score of 59/100, indicating significant user experience issues. The biggest problem is render-blocking CSS files that are delaying page rendering by 730ms, directly impacting how quickly users see content. The site is also suffering from excessive JavaScript execution (1.7 seconds), large layout shifts from improperly sized images, and a massive 2.9MB payload that takes too long to download. Addressing the render-blocking resources and optimizing the oversized images could improve load times by over a second and dramatically enhance the user experience.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+18 points estimatedWhy It Matters:
CSS files are blocking initial page render for 750ms, significantly delaying LCP and FCP.
How to Fix:
Use Next.js built-in CSS optimization by moving critical styles inline using styled-jsx or CSS-in-JS. Split large CSS files and load non-critical styles asynchronously using dynamic imports. Remove unused CSS from the main bundle using PurgeCSS or Next.js automatic tree-shaking.
Fix Image Layout Shifts
High Impact+15 points estimatedWhy It Matters:
Unsized images cause 0.295 CLS score, creating jarring content jumps that harm user experience.
How to Fix:
Add explicit width and height props to all Next.js Image components, especially partner logos and footer images. Use Next.js Image component's fill property with proper aspect ratios for responsive images. Implement proper image placeholders using blurDataURL to reserve space during loading.
