What does Shopify theme customisation involve?

Shopify theme customisation covers custom sections, product pages, templates, design, theme updates and performance. Page builder apps and pasted code snippets make a theme slower and harder to update with every change. Anthony McGrath does the work himself, with 22 years in digital marketing, for businesses in the UK, the US, Dubai and Australia.

Custom, without the mess

Page builder apps and pasted code snippets make a theme slower and harder to update with every change. Custom sections built into the theme do the same job faster, and they appear in the theme editor like any other section.

Every change is built on a duplicate theme, checked on real phones and tested against your apps before it goes live, so customers never see a half-finished page.

What's included

From one new section to a full redesign of your theme.

Before and after

An example of replacing a page builder with custom theme sections.

  • Product page load time on mobile: 5.4s before, 2.3s after
  • Add-to-cart rate: 6.1% before, 7.9% after
  • Page builder app fee: 49 a month before, 0 after

An example of the kind of change this work aims for, based on typical starting points. It is not a promise or a specific client result: every business starts somewhere different. Money figures are shown without a currency: the same pattern applies in pounds, dollars, dirhams or Australian dollars.

How it works

  1. Talk it throughA short call about your store, your products and what is holding sales back.
  2. Plan and priceA clear written plan: what gets built, in what order, how long it takes and what it costs.
  3. Build and testBuilt on a copy of your store, tested on real phones, then checked again before anything goes live.
  4. Launch and supportLaunched with tracking checked, then support afterwards so nothing is left half-finished.

Questions

Can you customise a premium theme?

Yes. Premium themes like Impulse, Prestige and Impact can be customised the same way, and changes are kept tidy so future theme updates are easier.

Will customisations break when the theme updates?

Theme updates can overwrite edits. I keep changes organised and documented, and can move them across to the new version for you.

Can my team edit the new sections?

Yes. Everything is built as proper theme sections with settings, so your team can add, move and change them in the theme editor.

Do you replace page builder apps?

Often. Page builders add weight and monthly fees. Rebuilding those pages as theme sections usually makes them faster and cheaper to run.
