Which apps add the most script weight without CRO benefit?

As an e-commerce store owner, I'm increasingly concerned about page load speed and its impact on conversion rates. I've noticed my Shopify store seems sluggish, and I suspect some of my installed apps might be contributing unnecessary script weight without providing meaningful conversion optimization. I want to understand which apps typically add the most bloat to my site and how to identify and remove performance-draining applications that aren't delivering real value to my business.

TL;DR - Quick Answer

Performance-heavy apps like complex product customizers, excessive review widgets, and poorly optimized social proof tools often add significant script weight without proportional conversion benefits. Focus on lightweight, focused apps with minimal external script loading.
