Optimize Image Delivery and Format
High Impact+12 points estimated
Why It Matters
Images waste 500KB and delay LCP by 1.6 seconds due to oversized files and legacy formats.
How to Fix
In Webflow Designer, replace PNG images with WebP format for 50-70% size reduction. Use Webflow's responsive image settings to serve appropriately sized images - your 800x1559px image displays at only 280x546px. Enable Webflow's automatic image optimization in Project Settings.

What This Score Means
A score of 35 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 severe performance issues with a score of only 35/100. The biggest problem is enormous video files (over 12MB total) that are blocking page rendering, causing an extremely slow Largest Contentful Paint of 10.3 seconds and Time to Interactive of 50+ seconds. The site is also loading massive amounts of unused JavaScript (877KB) and CSS (58KB), plus hundreds of font files that further slow down the initial page load. Compressing or removing the large video files, eliminating unused code, and optimizing the excessive font loading could dramatically improve performance by 30+ points and make the site actually usable for visitors.
Other Optimization Recommendations
Reduce JavaScript Bundle Size
High Impact+18 points estimatedWhy It Matters:
Unused JavaScript wastes 877KB and blocks main thread for 3.8 seconds, preventing user interactions.
How to Fix:
Remove or defer reCAPTCHA scripts until form interaction using Webflow's custom code. Audit Memberstack implementation to load only when needed. In Webflow's Site Settings, move non-critical scripts from head to before closing body tag with async/defer attributes.
Implement Font Display Optimization
Medium Impact+8 points estimatedWhy It Matters:
Custom fonts delay text rendering by 780ms, causing invisible text during page load.
How to Fix:
In Webflow's Typography settings, add font-display: swap to all custom fonts from Adobe Typekit. Reduce the number of font weights loaded - currently loading 40+ font variants. Preload only the most critical font weights using custom code in the head section.
