Shopify Theme Development and Customization

A well-built custom Liquid theme delivers fast development, lower maintenance cost, and full access to Shopify's CDN and platform infrastructure without the engineering overhead of a separate frontend stack. Shero builds custom themes and Shopify OS 2.0 sections that perform, maintain, and convert.

Share of Shopify stores still running Liquid themes in 2026

95% of Shopify stores run Liquid themes as of 2026, and Shopify continues to invest heavily in Online Store 2.0 JSON templates, sections everywhere, app blocks, and native metafields. Headless is right for brands with dedicated frontend engineering teams and complex multi-storefront needs. For most Shopify brands, a well-built Liquid theme is the better investment.

48%

Of stores passed the Speed Test

Our Speed Benchmark of 1000 Shopify stores proved more than half of Shopify merchants are leaving performance gains and potentially revenue on the table. This is an opportunity for new and established merchants to rise on top of competitor online via perfomance only.

98%

Client Retention

98% of Shero's clients stay on retainer after their project closes. Custom themes require ongoing maintenance as Shopify updates the platform, new sections are added as the brand's content needs evolve, and performance is monitored as the app stack changes.

Premier Partner

Shero holds Shopify Premier Partner status, one of fewer than 150 agencies globally. Theme development at Premier level means the code is built to Shopify's OS 2.0 architecture standards, not a legacy pattern dressed up to look modern.

Looking to align their online store with their unapologetic brand identity, the brand partnered with Shero to overhaul their Shopify theme, develop a dedicated evergreen product strategy, and drive stronger conversions.

What Shero covers under theme development

Everything is built to Shopify's platform standards so it holds through platform updates rather than breaking on the next Shopify release. The setup involves:

  • Full custom Shopify theme builds from design to Liquid code
  • Online Store 2.0 migration: converting legacy themes to JSON templates and sections everywhere
  • Custom section development for product pages, collection pages, and landing pages
  • Metafield-driven content architecture for editor-controlled page layouts
  • Performance optimization: PageSpeed audit, script deferral, image optimization, and lazy loading
  • App block integration so third-party apps render correctly inside OS 2.0 section architecture

Why brands work with Shero on theme development

Shero builds the performance architecture into the theme before any apps are added, not as a retrospective fix.

01

OS 2.0 architecture so editors control layouts without developer involvement

Online Store 2.0 introduced JSON templates and sections on every page not just the homepage. A theme built correctly on OS 2.0 means the marketing team can change page layouts in the theme editor without opening a developer ticket. A theme built incorrectly still has hardcoded product.liquid files, sections that don't support blocks, and metafields that require a third-party app. Shero builds to OS 2.0 standards from the first file.

02

Performance built into the architecture, not patched in afterwards

The average off-the-shelf Shopify theme ships with render-blocking scripts, unoptimized images, and CSS that loads whether or not the page needs it. Shero's custom themes start with a performance budget mobile PageSpeed above 75 is a delivery requirement, not an aspiration. The theme architecture is designed around that target before any design is coded.

03

Product page architecture built for conversion, not template defaults

The product page is where purchase decisions are made. A template default shows a title, price, and add-to-cart button. A Shero product page build structures the information hierarchy for the brand's specific buyer journey trust signals in the right place, specifications surfaced appropriately, reviews integrated without adding load time, and upsells placed at the point of highest intent.

04

Every theme engagement starts with a store audit

Before Shero touches a line of theme code on an existing store, a conversion and performance audit runs first. The audit identifies what the current theme is getting right, what's hurting conversion, and what changes have the highest revenue impact. The theme build then implements the findings rather than rebuilding for its own sake.

05

Theme built with the marketing program in mind

A theme built in isolation from the brand's marketing program produces a storefront where landing pages require developer time, campaign assets don't fit any existing section, and UTM-based personalization isn't possible without a separate app. Shero builds the theme to serve the campaigns that will run on it.

06

Theme development as part of a broader Shopify development engagement

Most brands need more than a theme. ERP integrations, custom Shopify Functions, and checkout customizations sit on top of the theme layer. Shero scopes theme development alongside the integration and app work so the theme architecture supports everything that runs on top of it from the start.
