Remove Unused CSS and JavaScript
Medium Impact+6 points estimated
Why It Matters
40KB of unused JavaScript and 34KB of unused CSS are unnecessarily slowing page load.
How to Fix
Use webpack-bundle-analyzer to identify unused code in Rails asset pipeline. Remove unused FontAwesome CSS (98% unused) and replace with specific icons. Split JavaScript bundles to load only required functionality per page using Rails code splitting.

What This Score Means
A score of 81 falls in the "Needs Improvement" 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 ClickFunnels landing page has good performance with a score of 81/100, but has significant room for improvement in Core Web Vitals. The biggest issue is render-blocking JavaScript files (jQuery, lazysizes, and intlTelInput libraries) that are delaying your First Contentful Paint by over 1 second and contributing to a slow Largest Contentful Paint of 3.7 seconds. The page is also loading 40KB of unused JavaScript and serving oversized images that are much larger than their displayed dimensions. Deferring non-critical JavaScript, minifying your custom scripts, and properly sizing your images could easily push your performance score above 90 and deliver a much faster user experience.
Other Optimization Recommendations
Defer Render-Blocking JavaScript Resources
High Impact+12 points estimatedWhy It Matters:
Critical JavaScript files are blocking page render and delaying FCP by 1.05 seconds.
How to Fix:
Move jQuery, lazysizes, and intlTelInput scripts to load after DOM content using defer attribute or async loading. In Rails, use javascript_include_tag with defer: true option. Consider inlining critical JavaScript directly in HTML to reduce network requests.
Optimize LCP Image Loading Performance
High Impact+8 points estimatedWhy It Matters:
LCP takes 3.7 seconds due to oversized images that are 4x larger than display dimensions.
How to Fix:
Resize hero image from 1000x279 to actual display size of 263x73 using Rails image processing gems like ImageMagick. Add fetchpriority='high' to LCP image element. Generate responsive srcset with multiple sizes using Rails Active Storage variants.
