Remove Unused JavaScript
High Impact+15 points estimated
Why It Matters
355 KiB of unused JavaScript is slowing page load by 1.85 seconds and blocking main thread execution.
How to Fix
Audit Google Tag Manager implementation to remove unused triggers and tags. Implement code splitting to load only necessary JavaScript per page. Use tree shaking to eliminate dead code from the 49KB app.js bundle. Consider replacing heavy third-party scripts with lighter alternatives.

AI Performance Analysis
This website has poor performance with a score of 57/100, indicating significant user experience issues. The biggest problem is render-blocking CSS files that are delaying the page from displaying content, causing a slow First Contentful Paint of 4.6 seconds and an extremely poor Largest Contentful Paint of 12 seconds. The site is also loading 355 KiB of unused JavaScript from Google Tag Manager and cookie consent scripts, further slowing down the page. Fixing the render-blocking resources could save 1.2 seconds of load time, while optimizing images and removing unused code could provide additional improvements of several hundred kilobytes in data savings.
Other Optimization Recommendations
Eliminate Render-Blocking CSS
High Impact+18 points estimatedWhy It Matters:
Multiple CSS files are blocking initial render, delaying LCP by 1.2 seconds and preventing users from seeing content.
How to Fix:
Combine the 6 separate block-specific CSS files (blockForm.css, blockTeamMember.css, etc.) into a single minified stylesheet. Inline critical above-the-fold CSS directly in the HTML head. Use media queries or loadCSS to defer non-critical styles until after page load.
Optimize Image Dimensions and Compression
Medium Impact+8 points estimatedWhy It Matters:
Case study images are oversized (500x500 vs 299x299 display) and poorly compressed, wasting 270 KiB of bandwidth.
How to Fix:
Implement responsive images using srcset with properly sized variants (299px, 598px for retina). Apply modern compression techniques to reduce file sizes by 40-50%. Convert PNG images to WebP format for better compression while maintaining quality.
