Shopify Accessibility Audit: Automated Testing vs Manual Testing: What’s the Difference?
Imagine a customer visits your Shopify store, finds the product they love, and tries to complete a purchase. However, they cannot navigate the menu using a keyboard, access meaningful image descriptions through a screen reader, or identify the checkout form fields. What happens next? They may leave without completing their purchase.
This is why accessibility matters for every Shopify business. An accessible store makes shopping easier for people with visual, hearing, motor, and cognitive disabilities. It also creates a smoother shopping experience for other visitors.
A Shopify accessibility audit helps identify and fix barriers that affect how people browse, interact with, and purchase products. Businesses typically use two testing approaches: automated accessibility testing and manual accessibility testing. While automated tools detect common technical issues, manual testing evaluates real user interactions and usability. In this blog, we’ll explore the differences between automated and manual accessibility testing and why Shopify stores need both.
What Is Automated Accessibility Testing?
Automated accessibility testing uses specialized tools to scan Shopify websites and identify common accessibility issues. These tools automatically evaluate page structure, HTML elements, color contrast, and other technical accessibility factors to identify potential issues and generate actionable reports for improvement. Popular accessibility testing tools include WAVE, axe DevTools, Lighthouse, Accessibility Insights, and Siteimprove Accessibility Checker. They help detect missing labels, contrast issues, and other accessibility errors quickly.
However, automated testing cannot identify every usability problem, so manual testing and human review are also necessary to ensure a better experience for all users.
What Is Manual Accessibility Testing?
Manual accessibility testing involves evaluating a Shopify store through real user interactions and assistive technologies. Accessibility specialists check whether visitors can browse products, select variants, complete forms, and make purchases without barriers. Common testing methods include keyboard-only navigation, screen reader testing using NVDA, JAWS, VoiceOver, and TalkBack, focus indicator evaluation, form and checkout testing, content readability assessment, and interactive element testing.
Unlike automated tools, manual testing helps identify usability issues that software may overlook, ensuring a more accessible and user-friendly shopping experience.
Automated vs Manual Accessibility Testing: The Key
Differences
Both automated and manual accessibility testing play an important role in creating an inclusive Shopify store. However, they deliver value in different ways. Automated testing helps identify common accessibility issues quickly and consistently, while manual testing uncovers usability barriers that can affect how real customers navigate, interact with, and purchase from your store.
Comparison Factor | Automated Accessibility Testing | Manual Accessibility Testing |
Testing Approach | Automatically scans your Shopify store to identify common accessibility issues. | Evaluates your store through real human interactions and usability testing. |
Testing Speed | Delivers quick results, helping teams identify issues without lengthy testing cycles. | Takes more time but provides deeper insights into the actual user experience. |
Cost Efficiency | Reduces repetitive testing efforts and makes routine accessibility checks more affordable. | Requires additional expertise and time but helps prevent costly usability oversights. |
Issue Detection | Identifies technical issues such as missing alt text, incorrect labels, and color contrast problems. | Uncovers usability barriers, confusing navigation, and accessibility issues that automated tools may overlook. |
Keyboard Accessibility | Checks certain keyboard-related accessibility requirements automatically. | Verifies whether customers can navigate menus, product pages, forms, and checkout using only a keyboard. |
Screen Reader Compatibility | Detects some screen reader-related code and labeling issues. | Evaluates how assistive technology users actually experience and navigate your store. |
Complex Accessibility Issues | May overlook context-dependent issues and complicated interaction barriers. | Identifies complex accessibility problems through practical testing and human judgment. |
Scalability | Makes it easier to scan multiple pages and perform regular accessibility checks as your store grows. | Requires more resources but provides deeper evaluations of important customer journeys. |
Customer Experience | Helps maintain technical accessibility across your storefront. | Ensures customers with different abilities can interact with your store more comfortably and independently. |
Business Value | Supports continuous monitoring and faster issue identification. | Helps improve usability, reduce customer friction, and create more inclusive shopping experiences. |
Best Suited For | Routine accessibility monitoring, initial scans, and identifying common technical issues. | Comprehensive accessibility audits, usability evaluation, and validating real-world shopping experiences. |
Why Do Shopify Stores Need Both Automated and Manual Accessibility Testing?
Relying on only one testing method can leave important accessibility problems undiscovered. Automated tools identify technical issues, while manual testing helps determine whether customers can use the store comfortably.
A combined approach offers several advantages:
Identifies both common and complex accessibility issues.
Validates automated scan results through human evaluation.
Improves keyboard and screen reader experiences.
Helps developers prioritize accessibility fixes.
Supports better Shopify WCAG compliance efforts.
Makes ongoing accessibility maintenance easier.
The World Wide Web Consortium also recommends combining automated testing with human evaluation when assessing WCAG conformance. For Shopify merchants, this means testing the entire shopping journey rather than focusing only on individual page elements.
How Can You Perform a Complete Shopify Accessibility Audit?
A Shopify accessibility audit identifies barriers that may prevent people with disabilities from browsing products or completing purchases. A structured checklist helps ensure the store is accessible throughout the shopping journey.
1. Identify Key Pages and User Journeys: Review essential pages, including the homepage, product pages, collections, cart, checkout, and contact forms.
2. Run Automated Accessibility Tests: Use tools like WAVE, axe DevTools, and Lighthouse to detect common accessibility issues.
3. Review and Prioritize Issues: Identify problems based on their severity and impact on the customer experience.
4. Test Keyboard Navigation: Ensure customers can navigate menus, select products, add items to carts, and complete forms using a keyboard.
5. Test With Screen Readers: Use NVDA, JAWS, VoiceOver, or TalkBack to check whether website content and controls are accessible.
6. Evaluate Key Store Elements: Check product filters, forms, menus, pop-ups, cart drawers, and checkout functionality.
7. Check WCAG 2.2 AA Compliance: Review color contrast, keyboard accessibility, focus visibility, text alternatives, form labels, and target sizes.
8. Fix Accessibility Issues: Update Liquid templates, HTML, CSS, ARIA attributes, and JavaScript to resolve identified barriers.
9. Retest and Document Changes: Verify completed fixes, record remaining issues, and maintain accessibility reports.
10. Schedule Regular Audits: Conduct accessibility checks after theme updates, app installations, redesigns, and major store changes
