We all love to post images on social media and often we're trying to figure out how to gain more followers to get more reach. One of the ways you can increase your audience is by adding descriptions to your images so that visually impaired people can enjoy them, too. These descriptions have different names: alt tags, alt text, alternative text, descriptions, or sometimes simply captions.In this tutorial, Allison teaches you how to add alt text in several social media platforms using her iPhone. You also learn how to use a free application called Be My Eyes to add incredibly good captions for your images using AI, saving you the trouble of thinking them up yourself.
