Eliminate Render Blocking CSS
High Impact+25 points estimated
Why It Matters
The main CSS file blocks rendering for 1.35 seconds, delaying both FCP and LCP significantly.
How to Fix
In Webflow Designer, go to Site Settings > Custom Code and add critical above-the-fold styles inline in the head tag. Use media='print' onload="this.media='all'" technique for non-critical styles. Remove 87% of unused CSS rules by auditing and cleaning up unused classes and components.

AI Performance Analysis
This Webflow site has poor performance with a score of 57/100. The biggest problem is render-blocking CSS that's delaying page rendering by 1.4 seconds, combined with 87% unused CSS code that's unnecessarily slowing down your site. Your Time to Interactive is extremely slow at 20.1 seconds, meaning users can't properly interact with your page for far too long. The most impactful fixes would be to defer or inline critical CSS, remove unused styles, and optimize your large images (especially the 426KB PNG file) to modern formats like WebP.
Other Optimization Recommendations
Optimize Image Delivery Strategy
High Impact+18 points estimatedWhy It Matters:
Images account for 643 KB of wasted bytes and use outdated formats, impacting LCP performance.
How to Fix:
In Webflow Asset Manager, replace PNG images with WebP format (350KB+ savings on home-1.png). Resize the expert card image from 1309x1440 to actual display size of 1244x700. Add explicit width and height attributes to all images including the logo and hero icons to prevent layout shifts.
Implement Efficient Caching Headers
Medium Impact+12 points estimatedWhy It Matters:
Poor cache lifetimes waste 275 KB on repeat visits and delay LCP by 150ms for returning users.
How to Fix:
Configure Webflow hosting settings or add Cloudflare to set longer cache headers for static assets. Set Facebook Pixel and tracking scripts to cache for at least 7 days instead of 20 minutes. Update image cache lifetime from 23 hours to 30 days minimum.
