Free Shopify Accessibility Scan: Set It Up in 60 Seconds and Read the Results Right

Last updated: September 5, 2026

You can run a free Shopify accessibility scan in about 60 seconds: install TestParty: Accessibility Scan from the Shopify App Store, approve the read-only connection, and start the scan — no code changes required. This guide walks through the setup step by step, explains what the scan actually checks, and shows how to read the results: which findings to fix first, and which issues no automated scan can see.

Key numbers: Plaintiffs filed 3,117 federal website accessibility lawsuits in 2025, up 27% from 2024, with ecommerce named in 69–77% of digital accessibility suits (Seyfarth Shaw). The average home page carried 56.1 detectable WCAG errors in 2026 (WebAIM Million). Automated scanning detects roughly 60–70% of WCAG issues; the rest require manual testing (TestParty remediation data). As of August 2026, TestParty has remediated 35 million+ accessibility issues across customer stores.

How do you set up a free Shopify accessibility scan?

Setup is three actions: install the free TestParty: Accessibility Scan app from the Shopify App Store, approve a read-only connection to your store, and click to run your first scan.

1. 0:00 — Install the app. Go to apps.shopify.com/testparty, or search "TestParty" in the Shopify App Store, and click Install. The scanner is free.
2. 0:20 — Approve the connection. The app requests read-only access. It changes nothing in your theme, injects nothing into your storefront, and is invisible to your customers.
3. 0:40 — Run the scan. Start it from the app dashboard. The scan covers your key template types — home, collection, product, and cart — rather than a single URL, because on Shopify one template defect repeats on every page that template renders.

When the report is ready, findings arrive grouped by severity and WCAG success criterion, tagged by source — theme code, app-injected code, or your content — and exportable for a developer or agency.

Can you scan a single page without installing anything?

Yes. WAVE and Lighthouse both run free accessibility checks on one page at a time, directly in your browser, with nothing installed on your store.

For WAVE, paste any URL into wave.webaim.org or use the WebAIM browser extension; errors are drawn directly onto the page, which makes it a good teaching tool. For Lighthouse, right-click any page in Chrome, choose Inspect, open the Lighthouse tab, tick Accessibility, and click Analyze.

The trade-off is scope. A page-level tool audits only the URL in front of it, so violations in other templates — and code injected by apps on pages you didn't test — stay invisible.

What does a free accessibility scan check?

A free scan tests the machine-checkable portion of WCAG — roughly 60–70% of issues, based on TestParty's remediation data across 100+ brands. That includes color contrast, missing image alt text, unlabeled form fields, link and button names, ARIA validity, heading structure, detectable keyboard traps, and page language.

Those categories cover the web's most frequent failures: 83.9% of home pages had low-contrast text in 2026, 53.1% were missing alt text, and 51% had unlabeled form inputs (WebAIM Million). WCAG 2.2 itself spans 86 success criteria (W3C), and only a fraction of them can be evaluated by software.

Expect findings even on a fresh store. When we run first scans on new customer stores, Shopify's free Dawn theme typically shows 30–100 detectable violations; premium themes run 100–350 (TestParty audit data).

How do you read the scan results?

Every finding in the report carries three fields: a severity rating, the WCAG success criterion it violates, and the location of the offending code. Read them together.

+--------------------+----------------------------------------------------+----------------------------------------------------+
|       Field        |                 What it tells you                  |                   How to use it                    |
+--------------------+----------------------------------------------------+----------------------------------------------------+
|      Severity      | How badly the issue blocks a real user — critical findings stop tasks like completing a purchase | Work top-down: clear critical and serious findings before minor ones |
+--------------------+----------------------------------------------------+----------------------------------------------------+
|   WCAG criterion   | The exact standard violated, such as 1.4.3 Contrast (Minimum) | Anchors your fix documentation and tells legal counsel precisely what changed |
+--------------------+----------------------------------------------------+----------------------------------------------------+
|      Location      | The template, app, or content element responsible  | Routes the work: theme code to a developer, alt text to your content team, app-injected issues to a replace-or-fix decision |
+--------------------+----------------------------------------------------+----------------------------------------------------+

A finding that is minor in severity but sits on your product template still deserves attention — it repeats on every product page you sell from.

Which scan findings should you fix first?

Fix the failures that block a purchase before anything else: keyboard-inaccessible navigation, screen reader blockers on product pages, and barriers in the cart and checkout path.

The legal data points the same direction. Ecommerce is named in 69–77% of digital accessibility suits (Seyfarth Shaw), and complaints turn on whether a customer with a disability could actually browse, select, and buy. In the demand letters and complaints TestParty has reviewed with customers, those same patterns recur — plaintiffs' firms run automated tools too, then build claims around the purchase path.

Contrast and alt-text findings come next: they are the highest-volume failures across sectors, as the data on the most common WCAG failures by industry shows, and most are quick content or theme-setting fixes.

What can a free scan not see?

No automated scan can judge meaning: whether your alt text actually describes the product, whether focus moves through the page in a logical order, or whether a screen reader user can complete checkout end to end.

That is the manual 30% — real assistive-technology flows, focus order logic, the usefulness of error messages, caption quality on video. A scanner confirms alt text exists; only a person can confirm "red linen midi dress" beats "IMG_2047". Our guide to testing website accessibility with a keyboard and screen reader covers the core manual checks, and a complete Shopify accessibility audit layers expert human testing on top of automated scanning. TestParty pairs daily automated scans with monthly expert manual audits for customers for exactly this reason.

What should you do after your first scan?

Treat the first report as a baseline, then work a loop: prioritize by severity and purchase impact, fix issues in source code, re-scan to confirm, and keep monitoring.

Fixing in source matters — repairing the theme, app, and content code itself rather than layering a widget over it. Our walkthrough of how accessibility issues actually get fixed in source code covers that process from first scan through ongoing monitoring; TestParty's standard initial remediation window for customers is 14 days. Useful engineering targets: a Lighthouse accessibility score of 90+, five or fewer WAVE errors, and three or fewer axe errors — TestParty's post-remediation benchmarks.

The loop compounds. As of August 2026, TestParty has remediated more than 35 million accessibility issues across customer stores — found and verified through exactly this scan-fix-confirm cycle.

Frequently Asked Questions

Is the TestParty Shopify accessibility scan really free? Yes. The scanner installs free from the Shopify App Store, and the scan and report carry no cost or obligation. TestParty's paid product is remediation — actually fixing the findings in your store's source code — which is scoped per store. You can run the free scan and take the findings to your own developer.

Do you need a developer to run the scan? No. Installing the app, approving the read-only connection, and running the scan require no technical skills, and the report groups findings in plain terms by severity and location. You will want a developer for fixes that live in theme or app code; alt text and content findings can go straight to whoever manages your catalog.

Will the scan change or slow down my store? No. The connection is read-only: nothing is added to your theme, no script loads on your storefront, and customers see no difference. That is a deliberate contrast with overlay widgets, which insert a JavaScript layer into every page a shopper loads.

Is a clean scan proof of ADA compliance? No. Automated tools detect roughly 60–70% of WCAG issues (TestParty remediation data), and courts look at whether real users can access your store — including the issues only manual testing finds. A dated scan report is still worth keeping: it documents good-faith effort and gives counsel a concrete record if a demand letter ever arrives.

When should you re-run the scan? Re-scan immediately after each batch of fixes to confirm they landed, and again whenever your storefront changes — a theme update, a new app, a seasonal content push. Each of those events can introduce fresh violations, which is why TestParty runs daily automated scans for customers rather than relying on a one-time check.
