Why It Matters
Critical CSS and JavaScript files are delaying First Contentful Paint by 950ms, significantly hurting user experience.
How to Fix
In Webflow Project Settings, enable 'Minify CSS' and 'Minify JavaScript'. Move the large webflow.schunk.91fef61251ff14a1.js (77KB) to load asynchronously by adding it through custom code with async attribute. Inline critical CSS for above-the-fold content in the head section.

AI Performance Analysis
This Webflow site has moderate performance issues with a score of 79/100, but there are significant opportunities for improvement. The biggest problem is render-blocking resources (CSS and JavaScript files) that are delaying the initial page load by nearly 1 second, combined with 595 KiB of unused JavaScript from Google reCAPTCHA and tracking scripts. The site is also loading a massive 9.9 MB video file that lacks proper caching, which severely impacts repeat visits and overall page weight. Addressing these render-blocking resources and implementing proper caching could potentially improve load times by over 1 second and significantly enhance the user experience, especially on slower connections.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+12 points estimatedWhy It Matters:
595KB of unused JavaScript is wasting bandwidth and blocking the main thread for 450ms.
How to Fix:
Remove or defer the reCAPTCHA script until form interaction occurs using custom JavaScript. Audit Google Tag Manager implementation and remove unused tags/triggers. Consider replacing heavy third-party scripts with lighter alternatives or load them conditionally.
Optimize Video and Asset Delivery
Medium Impact+8 points estimatedWhy It Matters:
The 9.9MB header video dominates page weight and lacks proper caching, slowing repeat visits.
How to Fix:
Compress the header video using a tool like HandBrake to reduce file size by 60-80%. Upload to a CDN like Cloudflare or use Webflow's native video optimization. Set proper cache headers in Webflow hosting settings or add cache-control meta tags for static assets.
