What is social media accessibility, and why does it matter?

The short answer

Social media accessibility means creating content that people with disabilities can perceive and understand. A screen-reader user needs alt text to know what an image shows, a Deaf or hard-of-hearing viewer needs captions to follow a video, and someone with low vision needs enough color contrast to read text overlaid on an image.

The most common gaps

A few specific, fixable gaps show up repeatedly:

• Images posted with no alt text, or alt text that is missing entirely
• Videos with no captions, or captions that are auto-generated and never checked for accuracy
• Text overlaid on a busy image or a low-contrast background, hard to read even for a sighted viewer
• All-caps or heavily stylized text that a screen reader may not read correctly

Why it is worth the small extra effort

Beyond reaching people who would otherwise be excluded from understanding a post at all, accessible practices like captions and clear contrast tend to help engagement broadly. Many people watch video with sound off, and high-contrast text is easier for everyone to read quickly while scrolling.
