WCAG 3.3.3: Error Suggestion
Level AAQuick answer: If the system can detect likely corrections, it should suggest them instead of leaving shoppers to guess.
What This Means
On ecommerce sites, Error Suggestion usually shows up in repeating storefront components such as product cards, PDP media, search results, cart drawers, checkout forms, and support content. If the live experience depends on patterns like address validation says only 'invalid address' without suggesting the corrected format. or email signup rejects typos like gmial.com without hinting at the probable issue., disabled shoppers can lose context or get blocked before purchase.
This criterion matters because D2C teams often fix the homepage but miss reusable app blocks, campaign pages, and mobile-specific UI. The practical standard is simple: build the same outcome for keyboard users, screen-reader users, low-vision users, and anyone relying on captions, labels, structure, or predictable behavior.
For Shopify, WooCommerce, and custom storefronts, the fastest remediation path is usually template-level work. Fix the repeated component once, then retest every place it appears across browse, buy, and post-purchase journeys.
Common Violations on Ecommerce Sites
- Address validation says only 'invalid address' without suggesting the corrected format.
- Email signup rejects typos like gmial.com without hinting at the probable issue.
- Payment forms fail CVV length checks without stating the expected length.
- Order lookup rejects numbers with spaces but never tells users to remove them.
How to Fix It
Start with the live customer journey, not isolated components in Storybook or Figma. Audit the problem on category pages, product detail pages, quick views, cart, checkout, account, and help templates.
- Provide specific suggestions such as expected format, length, or valid options.
- Offer correction hints only when they can be given safely and accurately.
- Tie suggestions to the field so screen readers announce them with the error.
- Use server-side validation responses to improve the specificity of client-side hints.
On Shopify, fix the theme section or app block that repeats the defect. On WooCommerce and WordPress, update the template override or plugin output. In custom React or headless storefronts, move the fix into shared components so merchandisers cannot reintroduce the issue with every campaign.
Code Example
<!-- Before -->
<p class="error">Invalid email.</p>
<!-- After -->
