AI Performance Analysis

This Webflow site has poor performance issues with a score of 52/100. The biggest problem is excessive unused JavaScript, particularly from Google Analytics and Facebook tracking scripts, which is wasting 470 KiB and blocking the main thread for 1.5 seconds. Additionally, the site has a very slow Largest Contentful Paint of 13.4 seconds due to render-blocking resources and inefficient image delivery. Removing unused JavaScript, optimizing images, and deferring non-critical scripts could improve the score by 30+ points and dramatically enhance user experience, especially on mobile devices.

Other Optimization Recommendations

Remove Unused JavaScript Code

High Impact+25 points estimated

Why It Matters:

470 KiB of unused JavaScript is delaying LCP by 1.7 seconds and blocking user interactions.

How to Fix:

In Webflow's Project Settings, remove unnecessary Google Analytics tracking codes (you have duplicates). Defer Facebook Pixel loading using custom code that loads after page interaction. Use Webflow's built-in analytics instead of multiple tracking scripts.

Fix Image Dimensions Properly

Medium Impact+8 points estimated

Why It Matters:

Missing image dimensions cause layout shifts and hurt user experience during page load.

How to Fix:

In Webflow Designer, select each image element and set explicit width/height values in the Style Panel. For responsive images, use Webflow's built-in responsive settings with defined aspect ratios. Add loading='eager' to hero images via custom attributes.
