Speed & Performance
Description
Your store is losing sales before the page even loads. We fix that.
We’re the team behind eComX, a family of Shopify themes built for speed and conversion. We’ve spent 9+ years optimizing Shopify stores and build our own tools for page size and performance, so we know where Shopify stores slow down and how to fix it.
What’s included
Full speed audit: Lighthouse and Core Web Vitals (LCP, CLS, INP) on your homepage, collection, product and cart pages, for both mobile and desktop.
App bloat cleanup: we find apps and leftover code that slow your store down, then remove or replace them.
Image & media optimization: image compression and resizing, modern formats and lazy loading, without visible loss of quality.
Script & code optimization: we defer or remove render-blocking scripts, clean up unused CSS/JS and tidy theme code.
Third-party script review: tracking pixels, chat widgets and review apps are loaded more efficiently.
Before/after report: scores and load times measured before and after, with a summary of every change.
Maintenance guide: recommendations to keep your store fast as you add apps and content.
Who this is for
Stores with low mobile PageSpeed scores or slow load times
Merchants with many apps installed over time
Brands running paid ads whose landing pages lose visitors to slow loads
What we need from you
Store access (collaborator account)
A list of apps and features you must keep
Your main traffic pages (if they differ from homepage/products)
