Recommendations for Improving Accessibility of Social Media by HowTo.gov

HowTo.gov has a great article on how to make Facebook and other social media accounts accessible to people with disabilities. Here is the run-down for the Facebook article:

"Tips for Making Facebook Posts Accessible
For General Account Information
Ensure your website address is listed in the About section of your Timeline/Page in order to provide an easy point of entry to more information.
Include other ways to contact your organization, such as your 800 number, an online “Contact Us” form, or general contact email address for more information.

For Photos, Video, Audio
Always provide a link back to a .gov page that hosts a copy of the photo, video, or audio with full caption/transcript.
After posting the photo, video, or audio, immediately post a comment that directs users to the full caption or the full transcript.
If you have a YouTube channel, upload your video to your channel and make sure you enable closed-captions (you’ll want to upload your own transcript to make sure the captions are accurate). Then post a link to your YouTube video as your status update, rather than uploading the video into Facebook. This will ensure that visitors will be taken to your accessible version on YouTube.

For Composing Status Updates
Facebook provides ample space that allows you to spell out acronyms. Spell out the first instance of the acronym and add the acronym in parentheses after (e.g., U.S. Geological Survey (USGS)). This is especially helpful for those using screen readers, because after the name is heard the acronym is spelled out, and the user will associate the sound of the acronym with the full name."
