Accessibility on social media
Whether you use social media for work or to chat with friends, you are bound to create content for everyone. That includes people using screen readers.
Be careful with emojis
When you use an emoji, screen readers read its unicode name. This is the description of the emoji and it can be different from what you expect. For example, 🙏 is read as "folded hands" not a high five. Make sure to check the emoji's description in the Emojipedia before using it. You'll find it in the technical information.
Emojis can also mean different things in different places. For instance, 🤘 means rock on in many places. But it also implies the horns, a symbol for infidelity in mediterranean countries.
It's best to avoid a series of emojis in a post. Screen readers will read the unicode names out and repeat them as many times as you've used them. Also, prefer using emojis at the end of a post rather than in the middle of a sentence.
Image description or alt-text?
On social media too you need to describe images with alt-text. This is important for screen readers to describe images with important information. But it also works for anyone when the image hasn't loaded.
You can also add an image description at the end of your posts. Not everyone experiences disability in the same way. People who are visually impaired don't always use screen readers. You can see an example on one of Meryl Evans' posts on LinkedIn. Image description allows you to use more than the alt-text 125 characters. Whenever necessary, use both the alt-text and the image description.
#AboutHashtags
Each word making up your hashtag must be easy to read by people and assistive technologies. You can use a simple trick by using Title Case. Example: #ThisIsEasierToRead vs #thisisnotsoeasytoread. Developers call it Pascal Case. But this trick doesn't work for some dyslexic people. Capital letters and lowercase are usually hard to distinguish for them. Also, keep in mind that Instagram will automatically format hashtags in lowercase.
Don't fake bold and italic text
Although they make words stand out, faux bold, italic or columns don't work for people using screen readers. Screen readers will entirely skip those words, as they are not actual words but Unicode symbols. If you create faux columns, screen readers will still read lines after lines.
