Remove Unused JavaScript and CSS

High Impact+15 points estimated

Why It Matters

222 KiB of unused JavaScript and 12 KiB of unused CSS are wasting bandwidth and slowing down page load times.

How to Fix

Install Asset CleanUp plugin to disable unused CSS/JS on specific pages. Remove the completely unused Font Awesome CSS file since it's 100% unused. Configure Google Tag Manager and Hotjar to load conditionally only where needed instead of site-wide.

What This Score Means

A score of 80 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 WordPress site has good but improvable performance with a score of 80/100. The biggest problem is render-blocking CSS files that are preventing content from appearing quickly, delaying both First Contentful Paint (3.3s) and Largest Contentful Paint (3.8s) by an estimated 1.8 seconds. The site is also loading 222 KiB of unused JavaScript from tracking scripts (Google Tag Manager, Hotjar) and has inefficient font loading from Typekit that's causing text to appear slowly. Deferring non-critical CSS, removing unused tracking code, and optimizing font display could improve your score by 15+ points and significantly speed up how quickly users see your content.

Other Optimization Recommendations

Eliminate Render Blocking CSS

High Impact+25 points estimated

Why It Matters:

Render blocking CSS is delaying your First Contentful Paint and Largest Contentful Paint by 1,770ms, significantly impacting user experience.

How to Fix:

Use WP Rocket or Autoptimize to defer non-critical CSS files. Inline critical above-the-fold CSS directly in the HTML head. Move Elementor widget-specific CSS files to load after initial render using async loading or conditional loading based on widget usage.

Optimize Web Font Loading

Medium Impact+8 points estimated

Why It Matters:

Adobe Typekit fonts are causing 30ms delays and contributing to layout shifts during font loading.

How to Fix:

Add font-display: swap to your Typekit configuration to show fallback fonts immediately. Implement font metric overrides in your WordPress theme's CSS to prevent layout shifts. Consider self-hosting critical font weights to reduce external dependencies.
