Quick Answer: To add alt text to an image on Twitter, upload the image and look for the Alt Text prompt.

When you post an image on Twitter, you may want to add alt text before you hit tweet.

Why? Because adding a description allows screen readers to explain the image to someone who’s visually impaired.

On top of that, search engines use this information to categorize content and provide more accurate results.

Also, if an image doesn’t load for whatever reason, alt text provides a description of what you’re meant to see.

In truth, adding a bit of descriptive text isn’t a time-consuming task. Let’s discuss how to add alt text to images on Twitter.
