Why It Matters

AI Performance Analysis
This website has severe performance issues with a critically low score of 28/100. The biggest problems are massive amounts of unused JavaScript (546 KiB) and render-blocking scripts that delay page rendering by 1.7 seconds, causing extremely slow loading times with pages taking over 9 seconds to become visually complete. The site is also bloated with a 5.6 MB total payload and suffers from 11.6 seconds of main-thread blocking work. Removing unused JavaScript, deferring non-critical scripts, and optimizing the numerous WooCommerce plugins could dramatically improve performance and user experience.
Other Optimization Recommendations
Remove Unused JavaScript Resources
High Impact+25 points estimatedWhy It Matters:
Unused JavaScript wastes 546 KiB and delays LCP by 800ms while blocking the main thread.
How to Fix:
Remove or defer Google Tag Manager script (107KB unused). Audit WooCommerce and payment gateway scripts for unused code. Use code splitting to load only necessary JavaScript per page. Configure async loading for analytics and tracking scripts.
Eliminate Render-Blocking Resources
High Impact+20 points estimatedWhy It Matters:
Critical render path is blocked for 1,720ms, preventing First Contentful Paint from occurring sooner.
How to Fix:
Move jQuery and WooCommerce scripts to load after DOM parsing using async/defer attributes. Inline critical CSS for above-the-fold content. Use resource hints like preload for essential fonts and defer non-critical CSS until after page load.
