Remove Unused jQuery Code

Medium Impact+3 points estimated

Why It Matters

75% of jQuery (23KB) is unused, creating unnecessary network overhead and parse time.

How to Fix

Audit your WordPress theme and plugins to identify actual jQuery dependencies. Use WP Rocket's 'Delay JavaScript execution' feature to defer jQuery until user interaction. Consider replacing simple jQuery functions with vanilla JavaScript or remove entirely if not needed.

AI Performance Analysis

This WordPress site performs exceptionally well with a score of 99/100, indicating excellent optimization overall. The main opportunities for improvement involve cleaning up unused code - specifically removing 23 KB of unused JavaScript (primarily from jQuery) and 17 KB of unused CSS rules. Additionally, minifying a WP Rocket plugin file could save another 6 KB. While these issues aren't affecting Core Web Vitals metrics, addressing them would reduce bandwidth usage and create an even leaner, faster-loading site.

Other Optimization Recommendations

Optimize CSS Delivery

Medium Impact+3 points estimated

Why It Matters:

77% of CSS (17KB) is unused, slowing down initial page rendering and resource parsing.

How to Fix:

Use Asset CleanUp Pro to disable CSS from unused WordPress plugins on specific pages. Implement critical CSS extraction using WP Rocket's critical CSS feature. Move non-critical CSS to load after page render using media='print' onload technique.

Minify WP Rocket JavaScript

Low Impact+1 point estimated

Why It Matters:

WP Rocket's beacon script is unminified, wasting 6KB of bandwidth and parse time.

How to Fix:

Update WP Rocket to the latest version which includes minified assets. If issue persists, contact WP Rocket support or manually minify the beacon.js file. Enable WP Rocket's 'Minify JavaScript files' option to catch other unminified scripts.
