Optimize Image Delivery and Sizing
Medium Impact+8 points estimated
Why It Matters
Images lack proper dimensions causing layout shifts and are over-compressed, wasting 135KB of bandwidth.
How to Fix
Add explicit width and height props to all Next.js Image components to prevent CLS. Use Next.js Image optimization with quality=75 for better compression. Implement proper responsive images with srcSet for different screen sizes.

AI Performance Analysis
This Next.js site performs well overall with a score of 93/100, but has one critical issue: it takes 9.2 seconds to become fully interactive, which is extremely slow for user engagement. The main culprits are render-blocking CSS that delays initial page display by 160ms and excessive unused JavaScript from tracking scripts (Facebook Pixel, Google Tag Manager, Ringostat) that waste 310KB of downloads. Additionally, the site uses outdated JavaScript polyfills that aren't needed for modern browsers, adding unnecessary 36KB. Optimizing these tracking scripts, deferring non-critical JavaScript, and modernizing the code could dramatically improve interactivity while maintaining the excellent loading performance.
Other Optimization Recommendations
Eliminate Render-Blocking CSS
High Impact+15 points estimatedWhy It Matters:
CSS is blocking initial render and delaying First Contentful Paint by 150ms.
How to Fix:
Use Next.js font optimization with next/font to inline critical CSS. Extract above-the-fold styles and inline them in the document head. Defer non-critical CSS using media='print' onload trick or dynamic imports.
Reduce JavaScript Main Thread Blocking
High Impact+12 points estimatedWhy It Matters:
240ms of main thread blocking time prevents user interactions and delays Time to Interactive.
How to Fix:
Remove 310KB of unused JavaScript from analytics scripts. Use Next.js dynamic imports for heavy components that aren't immediately needed. Configure webpack to split vendor chunks and enable code splitting for analytics libraries.
