Social alt text

You have limited control over people’s experience on social platforms, but you can make it better by minding a few details.

Issue: The post contains an image or or a card that combines text and an image. If you drag your cursor over the text and can’t highlight it, a screen reader can’t “see” it.  Without good, contextual alt-text that information is hidden from blind users.

Who’s affected: Screen reader users (blind), people with slow or weak internet (alt text is what shows up on the screen if the image is slow to load)

WCAG standard: Guideline 1.1: Non-text content

Add alt text, ideally before posting (that seems to be the easiest). Steps vary, so check your specific platform for the details. 

Recommended tools: Sprout, Buffer (both for scheduling), AltTxtReminder (Twitter). Also check out our video captions resources if you’re posting video.
