Alt Text is most often used in order to provide people who are blind and low vision access to online visual information.
What is Alt Text anyway?
Read this excerpt from our accessibility guide below!
Similar to Audio Description, Image Descriptions and Alt Text is most often used in order to provide people who are blind and low vision access to visual information. But whereas Audio Descriptions are audio-based and primarily used for video, Alt Text and Image descriptions are text-based and meant to describe still images for those who use screen readers to navigate the web, or for anyone who has trouble understanding the visual information in an image.
While Alt Text and Image Descriptions include similar information, the key difference between Alt Text and Image Descriptions is where and how they appear online. Alt Text is a type of “hard-coded” metadata associated with an image that exists as html. It is most often included in an “Alt-Text” field when uploading an image. In addition to providing accessibility, this text helps search engines learn what your image is about, and can improve your website’s SEO significantly.
Image Descriptions are usually more detailed than Alt Text, and are most often included in the body of a post or share text.
