AI Performance Analysis
This WordPress site has poor performance with a score of 48/100. The biggest problem is excessive JavaScript blocking the page load, causing a painfully slow Time to Interactive of 20.3 seconds and Total Blocking Time of 1,210ms. The site is loading massive amounts of unused JavaScript (275 KiB of waste) from Google Tag Manager and other plugins, while also suffering from unoptimized legacy JavaScript that could save 16 KiB. Additionally, 26 KiB of unused CSS is delaying the First Contentful Paint. Cleaning up JavaScript dependencies, removing unused code, and optimizing the plugin stack could improve the score by 30+ points and dramatically reduce page load times.
Other Optimization Recommendations
Reduce JavaScript Execution Time
High Impact+15 points estimatedWhy It Matters:
2.2 seconds of JavaScript execution blocks the main thread and delays interactivity by 1,210ms.
How to Fix:
Use WP Rocket to defer jQuery and Swiper.js loading until after critical content loads. Remove or replace heavy Elementor animations with CSS alternatives. Audit jet-search and jet-tricks plugins - consider lighter alternatives or disable unused features in their settings.
Optimize Font Loading Strategy
Medium Impact+8 points estimatedWhy It Matters:
Font display issues cause 60ms delay in First Contentful Paint and potential layout shifts.
How to Fix:
Add font-display: swap to your Hanken Grotesk Google Fonts in Elementor > Global Settings > Typography. Use font metric overrides to prevent layout shifts during font loading. Consider self-hosting fonts with preload hints for better performance control.
