I've been building websites since 1997. One thing that hasn't changed: accessibility gets treated as an afterthought more often than not. On Shopify, that's a problem, because the platform gives you a solid starting point and then hands the wheel to you. What you do with it determines whether your store actually works for everyone.

This post covers what we build into every Shopify store we develop, why it matters, and what store owners need to watch after we hand things off.

Why We Build Accessible Shopify Stores

Legal compliance is part of it. But honestly, the stronger reason is simpler: accessible stores reach more people and perform better.

We build to WCAG 2.1 Level AA because that's what ADA Title III requires and what courts apply. We also build that way because semantic HTML, clear navigation, and descriptive content are exactly what search engines and AI agents need to index and rank your store correctly. A 2025 Semrush study of 10,000 websites found WCAG-compliant sites received approximately 23% more organic traffic. Accessibility and SEO are the same work.

Then there's the market itself. Roughly 61 million Americans have a disability. Add 71 million Boomers, the first generation navigating digital commerce with changing vision and dexterity, controlling over $548 billion in discretionary spending. These are customers actively looking to buy. Inaccessible stores turn them away before they get to a product page. They leave and don't come back.

We build accessible Shopify stores because we want your store open to as many visitors as possible. Compliance is the floor, not the ceiling.

Shopify Gives You a Foundation. Not a Finished Store.

Shopify's default Dawn theme is genuinely well-built from an accessibility standpoint. Semantic HTML, skip navigation, ARIA landmarks, a hosted checkout built to WCAG 2.1 Level AA. That's a real head start.

The moment you start customizing, adding apps, and building out product pages, you're building on top of that foundation. Every layer you add is your responsibility to keep accessible. Shopify can't audit your customizations. It can't police your third-party apps. It doesn't know what your developers changed.

Most stores drift from that foundation faster than their owners realize.

What We Build In From the Start

Accessibility isn't something we add at the end of a Shopify build. It's baked into how we write code.

Semantic HTML structure. Every page we build uses correct heading hierarchy, proper landmark regions, and meaningful element choices. This isn't just for screen reader users. Search engines and AI agents read the same structure. A well-built page is easier to index, easier to rank, and easier for AI-driven search to cite.

Keyboard navigation. Every interactive element, menus, cart drawers, modals, product image galleries, works without a mouse. We test this manually on every build, not just run it through a scanner.

Color contrast. We check every color combination against WCAG 2.1 Level AA contrast requirements before anything goes live. Brand colors that fail get flagged early, not after the design is finalized.

Alt text strategy. We set up the alt text fields correctly and brief store owners on how to write useful alt text for product images. Shopify provides the field. Filling it in correctly is a content job, and we don't leave clients guessing on how to do it.

ARIA only where it's needed. A lot of developers reach for ARIA attributes to patch broken HTML. We don't. ARIA is for enhancing semantics, not fixing structural problems. When we use it, it's intentional and tested.

Third-party app vetting. Before we recommend or integrate any app, we check its accessibility. A lot of popular Shopify apps inject code that breaks keyboard navigation or creates screen reader traps. We've walked clients away from apps they wanted because the accessibility impact wasn't worth it.

What Can Break After Handoff

This is the part most agencies skip. A store that's accessible on launch day can drift quickly once the client takes over.

Content edits. Adding product images without alt text, pasting in formatted text that disrupts heading structure, embedding videos without captions. These are common and they add up.

New apps. Every app added after launch is a new accessibility variable. Some are fine. Some aren't. There's no automatic vetting once we hand things off.

Theme updates. Shopify pushes theme updates. Applying them without reviewing what changed can overwrite accessibility fixes.

Overlay apps. We occasionally inherit stores that have installed an accessibility overlay widget. We remove them. They don't fix underlying code. They patch over it, and they've been named in ADA lawsuits. Our sister company Accessibility.Works has written about this in detail if you want the full picture.

Wrap Up

Shopify makes it possible to build an accessible store. It doesn't make it automatic. The work happens at the development layer and the content layer, and it requires someone who knows what they're doing at both.

If you're planning a Shopify build or rebuild and want accessibility handled properly from the start, let's talk about what that looks like for your store. If you already have a store and want to know where it stands, our sister company Accessibility.Works offers Shopify accessibility audits.
