The problem

Why is my Shopify store slow on mobile?

A Shopify store is usually slow because weight has built up: apps piled up over the years, huge unoptimised images, scripts nobody uses, and theme code that blocks rendering. The result is slow mobile pages and failing Core Web Vitals, and past speed fixes often don’t last. Mooshfy finds exactly what slows your store, removes it, and stops it creeping back.

  • Pages take too long to load on mobile
  • Apps have piled up over the years
  • Images are huge and unoptimised
  • Core Web Vitals are failing
  • Scripts load that nobody uses
  • Past speed fixes didn’t last

We find exactly what slows your store, remove it, and stop it creeping back.

The outcome

What should Shopify speed optimisation achieve?

Speed optimisation should give you faster load and interaction on the phones customers use, passing Core Web Vitals, fewer apps on every page, and speed that lasts. Mooshfy measures before and after on your own store using field data from real devices, not lab scores, and adds a budget and monitoring so pages for Hong Kong shoppers stay fast.

01

Faster pages

Quicker load and interaction on the phones customers use.

02

Passing Core Web Vitals

Better experience, and a healthier search signal.

03

Fewer apps

Only what earns its place on the page.

04

Speed that lasts

A budget and monitoring so it stays fast.

What we deliver

What does Shopify speed optimisation include?

Shopify speed optimisation includes a Core Web Vitals audit of LCP, INP and CLS on real devices, image optimisation, removal of unused apps and leftover code, theme code fixes for render-blocking JavaScript, font and asset tuning, and ongoing monitoring. Mooshfy hands over an audit report, a prioritised fix list, the implemented optimisations, before/after Core Web Vitals and a monitoring setup. For Hong Kong brands, we set up FPS, Octopus and AlipayHK at checkout, price in HKD, and keep invoicing IRD-ready.

Core Web Vitals audit

We measure LCP, INP, and CLS on real devices to find what your shoppers actually feel.

Image optimization

We optimise your images — modern formats, correct sizing, lazy loading — usually the biggest win.

App & script cleanup

We remove unused apps and leftover code that quietly bloat every page.

Theme code optimization

We defer non-critical JavaScript and eliminate render-blocking resources.

Font & asset tuning

We speed up fonts and assets so the first paint arrives sooner.

Ongoing monitoring

We keep an eye on performance so it doesn’t regress as you add features.

What you keep
  • Performance audit report
  • Prioritised fix list
  • Implemented optimisations
  • Before/after Core Web Vitals
  • Monitoring setup

Why Mooshfy

How do you choose a Shopify speed optimisation agency?

Mooshfy is built around those four, with a fixed price in writing and code you own.

Real users, not just Lighthouse

We optimise for field data, not a lab score.

Developers, not plugins

Fixes in the code, not another speed app on top.

Straight answers

What worries brands about hiring an agency for speed optimization?

The usual worries are cost creep, slow communication, juniors doing the work, lock-in and paying for work the store does not need. Mooshfy answers each one with a commitment you can hold it to:

The worryWhat Mooshfy does
It will cost more than quotedScope and a fixed price are agreed in writing before work starts. The number does not move unless the scope does.

How it works

How does Shopify speed optimisation work?

Shopify speed optimisation at Mooshfy runs in six steps: Measure, Find the weight, Remove, Optimise, Verify and Protect. We take real-user Core Web Vitals, cost every app, script, image and font, take out what is unused, rework images, loading order and theme code, compare before and after on the same pages, then set a budget and monitoring.

  1. 01

    Measure

    Core Web Vitals from real users, plus lab tests on the pages that sell.

  2. 02

    Find the weight

    Every app, script, image and font accounted for and costed.

  3. 03

    Remove

    Unused apps and dead code taken out — the fastest code is no code.

  4. 04

    Optimise

    Images, loading order, theme code and third-party scripts reworked.

  5. 05

    Verify

    Before-and-after on the same pages and devices, checkout included.

  6. 06

    Protect

    A budget and monitoring so new apps do not quietly undo the work.

Technical capability

What does a Shopify speed audit look at?

A Shopify speed audit looks at Core Web Vitals (LCP, INP, CLS), every app and script, image formats and sizing, lazy loading, font loading, theme JavaScript and CSS, third-party tags, Liquid rendering, and caching and preloading. Mooshfy then tracks the results with real-user monitoring so new apps don’t quietly undo the work.

  • Core Web Vitals (LCP, INP, CLS)
  • App & script audit
  • Image formats & sizing
  • Lazy loading
  • Font loading
  • Theme JavaScript & CSS
  • Third-party tags
  • Liquid rendering
  • Caching & preloading
  • Real-user monitoring
Who it’s for

Does my Shopify store need speed optimisation?

Your Shopify store needs speed optimisation if mobile pages feel slow, Core Web Vitals are failing in Search Console, you run more than a handful of apps, your theme carries years of custom code, or you spend on ads that land on slow pages. Mooshfy works on a staging copy first for Hong Kong stores, so speed work doesn’t break the live store.

Speed work is worth doing if:

  • Mobile pages feel slow
  • Core Web Vitals are failing in Search Console
  • You have more than a handful of apps
  • Your theme has years of custom code
  • You spend on ads that land on slow pages
Questions

What do brands ask about Shopify speed optimisation?

These are the most common questions brands ask about Shopify speed optimisation — what slows a store down and whether fixing it is safe — answered by Mooshfy’s Shopify team. Anything not covered here, ask on WhatsApp — a real person replies in minutes.

Why is my Shopify store slow?

Usually heavy images, too many apps, and bloated theme code. We measure first, then fix the things that actually move the needle.

Will speed work break my store?

No — we work on a staging copy, test thoroughly, and only then apply changes to your live store.

How much faster will my store be?

It depends on what is slowing it down — usually apps, images and theme code. We measure on real devices before we start and again after, and report the change in Core Web Vitals, so you see exactly what improved.

How much does speed optimization cost?

There is no package price for speed optimization, because scope varies from store to store. Every project starts with a free audit or scoping call and ends that stage with a written scope and a fixed price — the number does not move unless the scope does. What drives the cost is how much of the store is involved, the features and integrations it needs, and the timeline.

Do you offer speed optimization for brands in Hong Kong?

Yes. Mooshfy delivers speed optimization for brands in Hong Kong with a senior team working worldwide. Every store is set up for how shoppers in Hong Kong pay: FPS, Octopus and AlipayHK at checkout, prices in HKD, and IRD-ready invoicing.

Which payment methods should a Shopify store in Hong Kong accept?
