To reach your audience, make sure everyone can access your posts.
All your pictures (including diagrams) should have an Alt text (alternative text) which will be read by a screen reader for users who can’t see them.
Here how to do this:
When you add a GIF, describe it [in square brackets]

Capitalise your Hashtags
Capitalising the first letter of each words on hashtags improves readability for screen reader users.
For example: #ThisIsHowtoFormatAnAccessibleHashtag
Caption your videos and multimedia
Advice from the Paciello group
Try not to use them too much. They are read aloud by screen readers. For example: 😃 would become “smiley face emoji”.
And don’t put them in your Twitter display name. In the tweet below, you can hear how a screen reader say the display name:
“Wheelchair symbol emoji — raised fist emoji — party popper Nicholas emoji — flag of Canada emoji — smiling face with smiling Steenhout at vavroom link”
This is read letter by letter by screen readers and you hear ‘mathematical’ a lot. So don’t use it!
Here is an example of how it sounds:
Hashtags and mentions should go at the end
The symbols # and @ are said aloud by screen readers, so it makes it harder to understand your post. Add them after your text. It will be clearer.
Avoid writing words or text in all Caps
It’s harder for everyone to read. The ‘shape’ of a word help us to identify it and this is lost with capitals. It can be misinterpreted by screen readers as well.
