Remove Unused CSS Rules

High Impact+15 points estimated

Why It Matters

85% of your main stylesheet (31KB) is unused, blocking render and delaying first paint by 150ms.

How to Fix

Use Webflow's built-in CSS optimization by removing unused classes and interactions in the Designer. Audit your style manager for orphaned styles. Consider splitting critical above-the-fold styles into a separate inline block in your page settings.

0Poor

What This Score Means

A score of 42 falls in the "Poor" 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 Webflow site has poor performance with a score of 42/100 and critical Core Web Vitals issues. The biggest problem is extremely slow image loading, with your Largest Contentful Paint taking 10.7 seconds - nearly 7 seconds slower than Google's recommended threshold. Your site is loading over 5.6MB of unoptimized images, including large PNG files that should be converted to modern formats like WebP, and oversized images that need proper compression. Additionally, there's significant JavaScript blocking (2.8 seconds of execution time) and 31KB of unused CSS slowing down your initial page render, resulting in a painful 16+ second Time to Interactive that will frustrate users and hurt search rankings.

Other Optimization Recommendations

Optimize Image Delivery Format

High Impact+25 points estimated

Why It Matters:

Large unoptimized images delay LCP by 6.6 seconds and consume 5.6MB of unnecessary bandwidth.

How to Fix:

In Webflow Designer, reupload the hero background (2.9MB PNG) and mascot GIF as optimized WebP/MP4 formats. Use Webflow's responsive image settings to serve appropriately sized images. Replace the meditation GIF with a compressed MP4 video for 70% smaller file size.

Add Image Dimensions Attributes

Medium Impact+8 points estimated

Why It Matters:

Images without explicit dimensions cause layout shifts when they load, degrading user experience.

How to Fix:

In Webflow Designer, select each image element and set fixed width/height values in the Style panel. For the hero images, add aspect-ratio CSS property via custom code. Use Webflow's responsive settings to maintain proper scaling across breakpoints.
