Remove Unused CSS Rules
High Impact+15 points estimated
Why It Matters
89% of your main stylesheet (36 KiB) goes unused, slowing initial page rendering unnecessarily.
How to Fix
Use a tool like PurgeCSS to remove unused CSS rules from your stylesheets. Split critical above-the-fold CSS and inline it directly in the HTML head. Defer loading of non-critical CSS using media='print' onload='this.media="all"' technique.

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 website achieves an excellent performance score of 99/100, indicating very fast loading times for users. The biggest optimization opportunity is reducing unused CSS, which could save 36 KiB by removing unnecessary styling rules that aren't being used on the page. Additional improvements include eliminating 62 KiB of unused JavaScript from Google Tag Manager, updating legacy JavaScript code to modern standards (saving 13 KiB), and extending cache lifetimes for third-party scripts. While these optimizations would further enhance performance, the site is already performing exceptionally well and provides an excellent user experience.
Other Optimization Recommendations
Optimize Google Tag Manager
High Impact+12 points estimatedWhy It Matters:
42% of your GTM script (62 KiB) is unused JavaScript that delays page interactivity.
How to Fix:
Review your GTM container and remove unused tags, triggers, and variables. Split tracking into essential (load immediately) and non-essential (defer until after page load). Consider loading GTM asynchronously after the window load event for non-critical tracking.
Fix Forced DOM Reflows
Medium Impact+8 points estimatedWhy It Matters:
Multiple forced reflows are causing layout thrashing and degrading page responsiveness.
How to Fix:
Batch DOM reads and writes to avoid repeated layout calculations. Cache geometric properties instead of repeatedly querying offsetWidth/height. Move style changes to requestAnimationFrame callbacks to align with browser paint cycles.
