WCAG 1.2.8: Media Alternative (Prerecorded)
Level AAAQuick answer: A full text alternative should cover all spoken and visual information for prerecorded synchronized media.
What This Means
On ecommerce sites, Media Alternative (Prerecorded) 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 brand mission videos offer captions but no complete text alternative covering visuals. or tutorial clips include visual annotations that are absent from the transcript., 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
- Brand mission videos offer captions but no complete text alternative covering visuals.
- Tutorial clips include visual annotations that are absent from the transcript.
- Video-only care guides lack a printable text walkthrough.
- Product training content for B2B buyers has no fully equivalent text version.
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.
- Publish a complete text alternative that includes dialogue, actions, and key visuals.
- Use the media alternative as a searchable support resource, not just a compliance artifact.
- Link to the full alternative directly under the video player.
- Keep transcripts updated whenever the video is revised.
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.
