Eliminate Unused JavaScript Execution
High Impact+20 points estimated
Why 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.

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.
