Fix Critical LCP Element Rendering
High Impact+25 points estimated
Why It Matters
Element render delay of 2.1 seconds is causing your LCP to reach 19 seconds, severely impacting user experience.
How to Fix
Add resource hints for the LCP image in your Shopify theme's head section using rel='preload'. Optimize the banner carousel component to render synchronously. Remove render-blocking CSS for slideshow components by inlining critical styles or using media='print' onload technique.

AI Performance Analysis
This Shopify site has severe performance issues with a critically low score of 29/100. The biggest problem is an extremely slow Largest Contentful Paint of 19 seconds, caused primarily by a massive 2.1-second delay in rendering the main carousel image after it loads. The site is also bloated with 2MB of unused JavaScript from Google Analytics and other scripts, plus 44KB of unused CSS, creating nearly 13 seconds of main thread blocking time. Immediate fixes should focus on optimizing the homepage carousel image loading, removing unused code, and deferring non-critical JavaScript to dramatically improve user experience and Core Web Vitals scores.
Other Optimization Recommendations
Eliminate Unused JavaScript Execution
High Impact+20 points estimatedWhy It Matters:
2MB of unused JavaScript is causing 8.5 seconds of execution time and blocking the main thread for nearly 3 seconds.
How to Fix:
Remove duplicate Google Tag Manager instances and unused tracking scripts. Use Shopify's Script Tag API to load analytics asynchronously. Implement code splitting for Klaviyo and Facebook Pixel to load only when needed. Consider replacing heavy third-party scripts with lighter alternatives.
Optimize Critical Resource Chain
Medium Impact+15 points estimatedWhy It Matters:
Resource load delay of 835ms and network dependency chains up to 10 seconds are preventing fast page rendering.
How to Fix:
Add preconnect hints for fast.wistia.net and api.config-security.com origins. Move font loading to use font-display: swap in your Shopify theme CSS. Bundle and minify critical CSS files to reduce the number of render-blocking requests from 490ms to under 100ms.
