Reduce JavaScript Bundle Size
High Impact+12 points estimated
Why It Matters
281KB of unused JavaScript is increasing LCP by 150ms and blocking main thread execution for 2.2 seconds.
How to Fix
Enable Next.js tree-shaking and dynamic imports for Google Analytics and large components. Use next/dynamic with ssr: false for non-critical components. Split vendor bundles and lazy load third-party scripts like Google Tag Manager after page interaction.

AI Performance Analysis
This Next.js site has good performance with a score of 81/100, but there's significant room for improvement. The biggest problem is render-blocking CSS files that are delaying your page's initial display by 570ms, particularly a large stylesheet that's 93% unused CSS. Your site is also loading 281KB of unnecessary JavaScript and using outdated JavaScript polyfills that add another 40KB of bloat. Cleaning up these unused assets and optimizing your CSS delivery could easily push your score above 90 and dramatically improve your 9.4-second Time to Interactive.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+15 points estimatedWhy It Matters:
CSS files are blocking initial render and delaying LCP by 550ms with 93% unused CSS rules.
How to Fix:
Use Next.js CSS optimization by splitting critical CSS with next/dynamic and code splitting. Extract above-the-fold CSS and inline it, then load remaining CSS asynchronously. Remove unused CSS rules from the 31KB stylesheet using PurgeCSS or Next.js built-in CSS tree-shaking.
Update JavaScript Build Target
Medium Impact+8 points estimatedWhy It Matters:
Legacy JavaScript polyfills add 40KB of unnecessary code for modern browsers supporting ES6+ features.
How to Fix:
Update Next.js config to target modern browsers by setting target: 'es2017' in next.config.js. Remove polyfills for Array.prototype.at, Object.hasOwn, and other modern features. Configure Babel to exclude unnecessary transforms for current browser support matrix.
