Boosting Mobile Sales: A Shopify Page Speed & App Audit
Client: A high-growth DTC (Direct-to-Consumer) apparel brand.
Challenges We Faced
The client’s “beautiful” Shopify theme was slow and clunky, especially on mobile:
App Bloat
The client had installed 15+ third-party Shopify apps (for pop-ups, reviews, tracking, etc.), which were loading 30+ external scripts.
Slow LCP
Large, unoptimized “hero” images and carousels on the homepage caused a 5-second LCP (Largest Contentful Paint).
High CLS
Pop-up apps and late-loading fonts were causing the layout to shift (Core Web Vitals failure), frustrating users.
“Liquid Code” Junk
Old, un-deleted code from uninstalled apps was still in the theme, adding to the bloat.
Poor Mobile Performance
The combined script bloat and render-blocking resources disproportionately hurt mobile users, where most traffic originated, further dragging down Core Web Vitals and conversions.
Speed Up Your Shopify Store
“Are third-party apps and large images slowing down your store? Our shopify page speed optimization service will fix it.”
Our Approach – How We Solved These Challenges
Shopify Page Speed Optimization
Our team used a Shopify Analyzer to find the slowest scripts and heaviest apps.
App & Plugin Analysis
We audited all 15 apps. We kept 10 essential ones and found lightweight, “scriptless” alternatives for 5.
Image Optimization & Next-Gen Formats
We compressed all homepage/collection images and converted them to WebP, saving 2MB on the initial page load.
Code Minification & Cleanup
We manually edited the theme.liquid file to remove “junk” code from uninstalled apps.
We deferred non-critical scripts (like the review app) to load after the page was interactive.
Results
| Metric | Before | After | Growth |

| Google PageSpeed Score (Mobile) | 41 | 88 | +114% |
| LCP (Largest Contentful Paint) | 5.2s | 1.8s | -65% |
| Mobile Conversion Rate | 1.1% | 2.5% | +127% |
