Speed and app weight
Auditing what each app loads on every page and replacing the heaviest with theme code that does only what you need. Usually the quickest measurable improvement available.

Shopify removes most of the infrastructure problems and leaves you two that matter: how fast the store is on a phone, and whether your catalogue can be found at all. We build and fix both, and because we also run the Shopping feeds, the product data gets done once rather than twice.

Quick answer
What actually limits a Shopify store
Two things, usually. Speed on a phone, and whether the catalogue is findable. Shopify handles hosting, payments and scale, so the ceiling is rarely infrastructure. It is apps slowing every page, and a collection structure that cannot rank for anything broader than a product name.
App weight is the commonest speed problem. Each app adds scripts to every page, and stores accumulate them the way WordPress sites accumulate plugins. Several apps can usually be replaced by a small amount of theme code that does exactly the needed job, which is both faster and one less subscription.
Findability is a structural question. Collection pages, not product pages, hold the terms with real search volume. A store with good products and thin, automatically generated collections is competing for exact product names and giving away everything broader. Shopify's default URL and tag behaviour also creates duplicate space that needs deliberate handling.
The product data behind both is the same data that feeds Google Shopping. Doing it once, properly, serves organic search, the Shopping feed and AI comparison answers together, which is why we would rather run those alongside each other than separately.
What we do
Shopify work we take on
Eight areas. Speed and catalogue structure are the usual starting points.
02
Theme development
Custom themes and substantial modifications, built so updates remain possible rather than forking the theme into something nobody can upgrade.
03
Custom app development
Private apps for the things Shopify does not do and the app store charges monthly for. Often cheaper within a year and considerably lighter.
04
Catalogue and collections
The structure that decides whether the store ranks for anything broader than product names, including deliberate handling of tag and filter URL space.
05
Shopping feed
Product data fixed at source so the feed, the store and the structured data agree. Done once rather than patched separately in three places.
06
Migrations
Onto Shopify from WooCommerce, Magento or custom, with URL mapping product by product and verification after launch.
07
Integrations
Connecting the store to ERP, finance, warehouse and fulfilment systems so stock and orders stop being reconciled by hand.
08
AI product visibility
Making product data machine-readable enough that assistants can include you when a buyer asks them to compare options.
Why stores stall
Good products nobody can find
The pattern repeats: a well-presented store, slow on mobile, ranking only for exact product names.
What we usually find
- Fifteen or more apps loading on every page
- Collections generated automatically and never written
- Tag and filter URLs creating large duplicate space
- A Shopping feed built from whatever the app exported
- Product content duplicated from the supplier
What we change
- App weight reduced, several replaced with theme code
- Collections written to win the terms with volume
- Duplicate URL space handled deliberately
- A feed built from product data that was fixed at source
- Product content that is yours rather than the supplier's
Store fast enough? Catalogue findable?
Those are the two questions that decide a Shopify store. The review answers both, and it is free.
How we work
Review, lighten, structure, grow
Speed and structure first, because they decide what everything else is built on.
1. Review
Store speed on a phone, app load, collection structure, URL space and the Shopping feed, looked at together. Free, in writing.
2. Lighten
Reduce app weight, replace the heaviest with theme code, and fix image and script delivery at the cause.
3. Structure
Collections written to hold the terms with volume, duplicate URL space handled, product data corrected at source.
4. Grow
Organic, Shopping and AI visibility run together, so the same product data serves all three.

Honest fit
When we suit a Shopify store
A small, fast, tidy store may need very little from an agency.
A good fit when…
- The store is slow on mobile and nobody knows why
- You are paying for apps that could be theme code
- Collections are automatic and rank for nothing
- You are migrating onto or off Shopify
- The Shopping feed and the store disagree
Not the right fit when…
- You have fifty products and a clean, quick store
- You want the cheapest possible theme install
- You need brand and campaign creative
- Your margins do not support any acquisition cost

FAQ
Shopify — FAQs
What UK retailers ask about Shopify work.
Still have a question?
Ask us directly — a senior engineer will get back to you.
Ask about your projectWhy is our Shopify store slow?
Almost always app weight. Each app adds scripts to every page, and stores accumulate them over time. Images served larger than they display and a theme doing too much work on load are the other two. All three are fixable without leaving Shopify.
Can you replace our apps with custom code?
Frequently, and it is often cheaper within a year as well as much lighter. Several apps each doing a fraction of what you need can usually become one small piece of theme code or a private app that does exactly the job and loads only where it is used.
Why do our collection pages not rank?
Usually because they were generated automatically and have no content beyond a product grid. Collection pages hold the terms with real search volume, so a store with strong products and thin collections competes for exact product names and gives away everything broader.
Can you migrate us onto Shopify?
Yes, from WooCommerce, Magento or custom platforms. The part that decides whether it goes well is URL mapping, done product by product and verified after launch rather than by pattern. That is where the large traffic losses happen.
Do you handle the Google Shopping feed too?
Yes, and we would rather do both. The product data that feeds Shopping is the same data that decides organic visibility and whether AI assistants can include your products. Fixing it once at source beats patching it separately in three places.
Is Shopify Plus worth it?
Only at certain volumes or for specific needs like checkout customisation and multiple storefronts. Below that the standard plan usually does the job and the difference is better spent elsewhere. We will give you a straight answer rather than an upsell.
Can you connect Shopify to our ERP?
Yes. Stock, orders, pricing and customer records between Shopify and finance, warehouse or ERP systems is ordinary integration work and it is a large part of what we do outside ecommerce.
Do we own the theme and any apps you build?
Yes. Theme code and private apps are yours, in your repositories, running in your Shopify account. We do not build things that stop working when the relationship ends.
What does it cost?
It depends on the size of the site and the scope of the work, so we do not publish a fixed price: the honest range is wide. The first conversation and the audit are free, and the quote follows them, in pounds, once we both know what the work actually is.
Who do we contract with?
SpiderHunts Technologies Ltd, registered at Companies House under number 16718403, with an office at 182-184 High Street N, Office 14607, London E6 2JA. You are invoiced in pounds. The engineering team works from Lahore, which we state openly rather than implying a room full of desks in London.
