Video without captions — the fix

One or more <video> elements do not have a <track> element with captions or subtitles, making the content inaccessible to deaf and hard-of-hearing users.

Where this fits: accessibility in SEO

Accessibility overlaps heavily with SEO because both depend on machine-readable structure: alt text, heading hierarchy, labels, contrast. Screen readers and search crawlers consume the same signals. Accessible sites rank better not by special treatment but because the same fixes — descriptive alt attributes, proper headings, real link text — are exactly what search engines parse for meaning. It is also, in a growing number of jurisdictions, the law.

Why video without captions hurts your rankings

WCAG 1.2.2 requires captions for all prerecorded audio content in synchronized media. Without captions, deaf and hard-of-hearing users cannot access spoken content in videos. Captions also benefit users in noisy environments, non-native speakers, and users who prefer reading.

This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it.

How to fix it

Add a <track> element with kind='captions' (or kind='subtitles') to each video element. Provide a WebVTT (.vtt) file with accurate, synchronized captions.

<video controls>
  <source src="video.mp4" type="video/mp4">
  <track kind="captions" src="captions.vtt" srclang="en" label="English" default>
</video>

Accessibility best practices

  • Give every informative image an alt attribute that describes its content; decorative images get alt="".
  • Maintain heading hierarchy — never skip levels for styling reasons.
  • Make link text meaningful out of context; screen readers list links in isolation.
  • Keep text contrast at WCAG AA (4.5:1) minimum.
  • Make everything keyboard-operable with a visible focus state.
