Remove Unused JavaScript Files

High Impact+18 points estimated

Why It Matters

Unused JavaScript wastes 274 KiB and delays LCP by 1.2 seconds while blocking main thread execution.

How to Fix

Deactivate the affiliate plugin if unused, or configure it to load only on relevant pages. Use Asset CleanUp Pro to selectively disable ApexCharts and MediaElement scripts on pages that don't need them. Consider replacing heavy chart libraries with lighter alternatives.

AI Performance Analysis

This WordPress site has poor performance with a score of 59/100. The biggest problem is an excessive amount of unused JavaScript (268 KiB) from affiliate and chart plugins that's delaying page loading by over a second, combined with 119 KiB of unused CSS that's further slowing things down. The site takes 10.3 seconds to display its main content, which is far too slow for users. Removing or deferring these unused scripts and styles, along with updating legacy JavaScript code that's adding another 28 KiB of unnecessary bloat, could improve the performance score by 30+ points and dramatically reduce load times.

Other Optimization Recommendations

Fix LCP Image Discovery

High Impact+15 points estimated

Why It Matters:

Your LCP element isn't discoverable in the initial HTML, preventing the browser from prioritizing its download.

How to Fix:

Add fetchpriority='high' attribute to your hero image or video poster. Remove lazy loading from above-the-fold images. Ensure hero content is directly in HTML rather than loaded via JavaScript or hidden in carousel slides.

Optimize CSS Delivery Performance

Medium Impact+12 points estimated

Why It Matters:

Render-blocking CSS and unused styles delay FCP by 2.35 seconds and waste 122 KiB of bandwidth.

How to Fix:

Use Autoptimize or WP Rocket to inline critical CSS and defer non-essential styles. Remove unused Dashicons CSS (35KB) with Asset CleanUp if admin features aren't needed. Minify the unminified CSS file in CommerceKit plugin.
