Remove Unused CSS and JavaScript

Medium Impact+10 points estimated

Why It Matters

213 KiB of unused code (53 KiB CSS + 160 KiB JS) delays rendering and wastes bandwidth, impacting LCP by 450ms total.

How to Fix

Use Asset CleanUp Pro WordPress plugin to disable unused Bootstrap CSS and FontAwesome on pages that don't need them. Remove or defer Google Tag Manager and Iubenda scripts until after page interaction. Audit your theme's bundle.js for unused code.

AI Performance Analysis

This WordPress site has poor performance with a score of 70/100, primarily due to a severe layout shift problem that's causing significant visual instability when the page loads. The biggest culprit is a custom web font (odudosoft-regular-webfont.woff2) that's causing the entire page content to jump around as it loads, resulting in a very poor Cumulative Layout Shift score of 0.639. Additionally, the site is loading a large 2.8MB video file and oversized images totaling over 4MB, which is slowing down the initial page load to 3.2 seconds. The quickest wins would be to add font-display: swap to prevent layout shifts, compress or replace that large video file, and optimize the image compression to reduce file sizes by about 123KB.

Fix Font Loading Layout Shifts

High Impact+25 points estimated

Why It Matters:

Web font loading causes a massive 0.639 CLS score, severely impacting user experience and Core Web Vitals.

How to Fix:

Add font-display: swap to your custom font CSS for odudosoft-regular-webfont.woff2. Implement font metric overrides in CSS to match fallback font dimensions. Preload the critical font file with <link rel='preload' as='font'> in your WordPress theme header.

Optimize Images and Reduce Payload

High Impact+15 points estimated

Why It Matters:

Images waste 123 KiB and the 2.8MB video file dominates your 4.1MB total payload, slowing LCP by 150ms.

How to Fix:

Increase compression on fitness-rig.webp and offers.webp files using WordPress plugins like ShortPixel. Convert the 18-years-banner PNG to WebP format. Consider replacing the large MP4 video with a compressed version or poster image for mobile devices.
