Accessibility Guidance for Social Media

All social media posts must be accessible to ensure the content is available for as many people as possible. 

Follow the guidance below to leverage the accessibility tools available on each social media platform and ensure your content meets digital accessibility standards

Best Practices

  • Include alt text on all photos, graphics and other static visuals.
    • If text is embedded on an image/graphic, include that text verbatim in the image description.
  • Add closed captions on all video content.
    • If a social media platform doesn't support closed captions, add open captions (burned-in text) directly to the video.
  • Make sure color contrast is accessible.
  • Use camelCase or PascalCase on hashtags that contain multiple words.
  • Avoid acronyms and initialisms in posts whenever possible, unless the acronym is widely recognizable (e.g. NASA).
  • Use a URL shortener to minimize characters.
  • Avoid using special fonts and typefaces.
  • Use emojis strategically and keep screen readers in mind.
    • Avoid using special characters to create images.
