Remove Lazy Loading from LCP Image
High Impact+25 points estimated
Why It Matters
The hero image has lazy loading enabled, preventing immediate discovery and delaying LCP by several seconds.
How to Fix
In Webflow Designer, select the hero background image element. In the Settings panel, remove the lazy loading attribute and add fetchpriority='high' to prioritize this critical resource. Consider setting this image as eager loading instead.

AI Performance Analysis
This Webflow site has severe performance issues with a score of 39/100. The biggest problem is an enormous network payload of 10MB, primarily from large Vimeo video files that are loading immediately rather than being deferred, causing your Largest Contentful Paint to take 5.4 seconds and First Contentful Paint to reach 4.3 seconds. The site also suffers from 616 KB of unused JavaScript and 77 KB of unused CSS that are blocking the initial render. Implementing video lazy loading, removing unused code, and optimizing the massive image files could improve your score by 30+ points and dramatically reduce loading times for users.
Other Optimization Recommendations
Optimize Video Content Delivery
High Impact+20 points estimatedWhy It Matters:
Vimeo video chunks consume 5.6MB of the 10MB total payload, severely impacting load times and Core Web Vitals.
How to Fix:
In Webflow, replace auto-playing background videos with optimized poster images on mobile. Use Vimeo's adaptive streaming with lower quality settings for mobile devices. Consider moving videos below the fold and implementing intersection observer-based loading.
Eliminate Render-Blocking JavaScript
High Impact+18 points estimatedWhy It Matters:
Critical JavaScript blocks initial page render for 3.3 seconds, preventing users from seeing content quickly.
How to Fix:
In Webflow's Project Settings, defer non-essential scripts by moving them to the 'Before </body> tag' section. Use async loading for third-party scripts like Optimizely and analytics. Consider removing or deferring GSAP animations until after first contentful paint.
