Remove Unused CSS and JavaScript

Medium Impact+12 points estimated

Why It Matters

98% unused CSS and legacy JavaScript polyfills waste 53KB and slow page rendering.

How to Fix

Remove unused CSS rules from bundle.css (24KB savings) and style.css (12KB savings). Update jQuery from v1.10.2 to modern version and remove legacy polyfills for String.trim and Array.forEach. Minify remaining CSS and JavaScript files to save additional 11KB.

What This Score Means

A score of 60 falls in the "Needs Improvement" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.

This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.

Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis

This website has poor performance with a score of 60/100, primarily due to severe layout stability issues. The biggest problem is an extremely high Cumulative Layout Shift score of 2.114 (anything above 0.1 is considered poor), caused by web fonts loading late and shifting page content around as users try to read it. The site also suffers from a slow Largest Contentful Paint of 4.2 seconds and has 36KB of unused CSS that's unnecessarily slowing down the page. Fixing the font loading strategy, optimizing images (which could save 107KB), and removing unused CSS would dramatically improve both the user experience and search rankings.

Other Optimization Recommendations

Eliminate Web Font Layout Shifts

High Impact+25 points estimated

Why It Matters:

Web fonts are causing 2.114 CLS score by loading late and shifting all page content.

How to Fix:

Add font-display: swap to all @font-face declarations in CSS. Preload critical fonts by adding <link rel='preload' as='font'> tags for Sora and DM Sans. Use font metric overrides or fallback fonts with similar dimensions to minimize layout shifts during font swaps.

Optimize LCP Image Loading

High Impact+18 points estimated

Why It Matters:

The main ERP image is oversized and delays LCP by causing forced reflows.

How to Fix:

Resize Hispamedia_Sistema_ERP.webp from 1536x688 to actual display size (669x299) to save 60KB. Add explicit width='669' height='299' attributes to prevent layout shifts. Move the image above the fold and ensure it loads before JavaScript execution.
