Eliminate Render-Blocking JavaScript Resources

High Impact+25 points estimated

Why It Matters

Critical JavaScript files are blocking page rendering for 1.6 seconds, directly delaying LCP and FCP.

How to Fix

Add async or defer attributes to UIKit.js, jQuery, and theme.js files. Use WP Rocket's 'Delay JavaScript execution' feature or manually modify script tags in functions.php. Consider moving jQuery to footer and using vanilla JavaScript alternatives where possible.

AI Performance Analysis

This WordPress site has below-average performance with a score of 72/100. The biggest problem is render-blocking JavaScript files (including jQuery and UIKit) that are delaying page rendering by an estimated 1.6 seconds, causing your Largest Contentful Paint to reach 4.9 seconds. The site is also loading 112KB of unused JavaScript from Google Tag Manager, jQuery, and theme files that could be removed or deferred. Fixing these JavaScript issues by deferring non-critical scripts and removing unused code could improve your score by 15-20 points and significantly speed up how quickly users see meaningful content.

Other Optimization Recommendations

Reduce and Optimize Unused JavaScript

High Impact+18 points estimated

Why It Matters:

112 KiB of unused JavaScript is wasting 450ms of load time and blocking LCP improvements.

How to Fix:

Remove unnecessary Google Tag Manager events and unused UIKit components. Use Asset CleanUp Pro to disable jQuery on pages that don't need it. Split large JavaScript bundles and load only required modules per page using WordPress conditional loading.

Minify JavaScript and Implement Caching

Medium Impact+12 points estimated

Why It Matters:

Unminified UIKit.js wastes 25 KiB and poor cache policies force unnecessary re-downloads.

How to Fix:

Enable JavaScript minification in WP Rocket or Autoptimize. Configure browser caching for 1 year on static assets via .htaccess. Move cookie-script.com to a CDN with proper cache headers or host locally with long expiration times.
