Accessibility of social media content is the responsibility of platform managers across Michigan Tech. Without following these guidelines, our social media content—whether consumed through embeds on our websites or through the original platform itself—may not be accessible by users with disabilities.
Alternative text or ALT tags are imperative in ensuring that our photo content is accessible. Unfortunately, most social media platforms (Twitter is a notable expection) do not allow their content creators to add alternative text to the images they post.
If the platform that you are using does not allow you to add alternative text to the images you post natively, you can do one of two things:
- If you are including no other text with the photo, include an image description or caption describing what is in the image along with the image you are posting.
- If you are including marketing language or other post content already, also include an image description in brackets afterward. For example: Register for our open house online. [Students studying on campus].
By posting an image caption or description within your social post, you are providing text that a screen reader can access.
Video captions or subtitles are necessary to make social media video accessible. Different social media platforms have different options for including captions:
- Facebook video captions
- Twitter video subtitles
- Instagram video captions are not natively possible (Instagram alternatives)
- Snapchat video captions are natively possible (Snapchat alternatives)
- YouTube video captions
- Vimeo video captions
