The legal landscape for e-commerce is shifting rapidly. By August 2026, the enforcement of the European Accessibility Act (EAA) and stricter interpretations of ADA Title III will make "good enough" accessibility a liability for online retailers.
For BigCommerce merchants, this means that simply having a "pretty" storefront isn't enough. If a customer using a screen reader cannot complete a checkout, or a user with motor impairments cannot navigate your product filters, your store is legally vulnerable.
In our experience consulting for high-volume retailers, we see many brands rely on "overlay" widgets as a band-aid. These often fail to meet WCAG 2.2 (Web Content Accessibility Guidelines) standards and can actually hinder navigation for some users.
To truly protect your business, you need to address the core architecture of your BigCommerce store. Here are eight critical fixes you must implement before the 2026 deadlines.
1. Fix Non-Descriptive Image Alt Text in Product Catalogs
The most common accessibility failure on BigCommerce stores is the use of generic or missing Alt Text (alternative text descriptions for images). When a screen reader encounters an image without a description, it may read the file name, such as "IMG_5542_final.jpg," which provides zero value to the user.
You must ensure every product image conveys the same information as the visual. Instead of "Blue Shirt," use "Men's slim-fit button-down shirt in navy blue with a cotton texture."
To fix this in BigCommerce:
- Navigate to Products in your admin panel.
- Select a specific product and scroll to the Images section.
- Click on an image to edit its properties.
- Enter a descriptive, concise sentence in the Alt Text field.
- Repeat this for every product in your catalog.
2. Correct Heading Hierarchy for Screen Readers
Many BigCommerce themes use "H1" or "H2" tags for styling purposes rather than structural purposes. This confuses screen readers, which use headings to create a "map" of the page content.
A proper hierarchy means you should only have one H1 (usually the Page Title). Subsequent sections should follow a logical order: H2 for main sections, H3 for subsections, and so on.
If your theme uses an H3 for a product price but an H2 for the "Related Products" section below it, the logical flow is broken. You should work with your developer to ensure the HTML tags reflect the actual importance of the content.
3. Ensure Keyboard Navigability for All UI Elements
A significant portion of users with motor disabilities navigate the web using only a keyboard. If a user cannot "Tab" through your navigation menu, product filters, or "Add to Cart" buttons, your store is non-compliant.
We often see BigCommerce stores where "hover" effects are the only way to trigger a dropdown menu. This is a major red flag for ADA website compliance.
To test this:
- Unplug your mouse.
- Try to navigate your entire store using only the Tab, Enter, and Spacebar keys.
- Ensure there is a visible Focus Indicator (a box or outline) showing which element is currently selected.
4. Audit Your Product Filter Sidebars
BigCommerce's advanced filtering capabilities are powerful, but they are often built with complex JavaScript that can be inaccessible. If a user cannot interact with a "Size" or "Color" filter via a keyboard, they cannot narrow down their search.
Ensure that your filter checkboxes and radio buttons are properly labeled in the code. Each input must have a corresponding <label> tag that is programmatically linked.
If you are using a third-party app for filtering, contact the developer to request a WCAG 2.2 compliance audit. If they cannot provide one, it may be time to switch to a more accessible solution.
5. Optimize Color Contrast for Readability
Low color contrast is a frequent reason for accessibility failures. If your "Sale" text is light gray on a white background, or your "Buy Now" button uses a pastel color with white text, it may be unreadable for users with visual impairments.
The WCAG 2.2 standard requires a contrast ratio of at least 4.5:1 for normal text.
You can use free tools like the "WebAIM Contrast Checker" to test your brand colors. If your primary brand colors don't meet the ratio, you may need to slightly darken the text or lighten the background to remain compliant.
6. Fix "Clickable" Elements Without Proper Labels
Sometimes, a button might only contain an icon, such as a magnifying glass for search or a shopping bag for the cart. If the code doesn't include an Aria-Label (Accessible Rich Internet Applications label), a screen reader will simply say "Button."
For every icon-only button in your BigCommerce theme, ensure the following attribute is present in the HTML:
aria-label="Search products" or aria-label="View shopping cart".
This small change ensures that the purpose of the button is communicated clearly to all users, regardless of how they interact with the site.
7. Simplify the Checkout Flow for Screen Readers
The checkout process is the most critical part of your store. Any friction here—such as a "hidden" error message that doesn't announce itself to a screen reader—can lead to abandoned carts and legal issues.
When a user enters an incorrect credit card number, the error message must be associated with the input field using aria-describedby. This ensures the screen reader immediately notifies the user of the mistake.
In the BigCommerce admin, you can often customize the checkout experience. Ensure that any custom fields you add are clearly labeled and that the "Place Order" button is the final, clearly defined action on the page.
8. Address Dynamic Content Updates
Many modern BigCommerce stores use AJAX to update the cart count or show "Added to Cart" confirmations without refreshing the page. If these updates aren't announced, a blind user might not know their action was successful.
To fix this, developers use ARIA Live Regions. These are specific areas of the code that tell the screen reader to announce any changes that happen inside that box.
For example, when a user clicks "Add to Cart," a live region should announce: "Item added to cart. Current total: $50.00."
The Role of AI in Accessibility Compliance
Manually auditing every single product page and interaction is a massive undertaking for most merchants. This is where Accessio.ai becomes a valuable asset for BigCommerce users.
Unlike "overlay" widgets that simply sit on top of your site and often break functionality, Accessio.ai works at the source code level. It uses AI to identify and fix underlying structural issues, ensuring that your store meets digital ADA standards without compromising the user experience.
By using an AI-powered approach, you can move from reactive "patching" to proactive compliance, ensuring your store stays ahead of the 2026 regulations.
Comparison: Overlays vs. Source Code Fixes
| Feature | Overlay Widgets | Source Code Fixes (Accessio.ai) |
|---|---|---|
| Compliance Level | Often fails legal audits | Meets WCAG 2.2 standards |
| User Experience | Can interfere with navigation | Invisible and seamless |
| Implementation | Quick "plug and play" | Fixes issues at the root |
| SEO Impact | Can sometimes slow down site | Improves site structure and SEO |
| Legal Protection | Low (easily challenged) | High (industry standard) |
Key Takeaways
- Deadline Awareness: August 2026 is a critical milestone for EAA and ADA compliance; start your audit now.
- Beyond Aesthetics: Accessibility is about functionality. If a user can't complete a purchase, the store is non-compliant.
- Avoid Overlays: Relying solely on widgets is no longer a sufficient legal defense against ADA lawsuits.
- Focus on Core Elements: Prioritize Alt Text, Heading Hierarchy, Keyboard Navigability, and Color Contrast.
- Automate with AI: Use tools like Accessio.ai to identify and repair deep-seated code issues that manual audits might miss.
Frequently Asked Questions
Does BigCommerce provide accessibility out of the box? BigCommerce provides a compliant platform framework, but your specific theme, third-party apps, and product content are your responsibility. You must audit your unique content and customizations.
Will fixing accessibility help my SEO? Yes. Search engines prioritize sites that are easy to crawl and navigate. Many accessibility best practices, such as proper heading structures and descriptive Alt Text, directly improve your SEO.
How much does it cost to make a store accessible? Costs vary depending on the complexity of your theme. However, proactive fixes are significantly cheaper than the legal fees and settlements associated with an ADA lawsuit.
Next Steps
- Perform a Manual Audit: Spend 30 minutes navigating your store using only your keyboard to identify immediate "blockers."
