Image Alternative Text and Why It’s
Important
Alternative text (or alt text) is written
copy that appears in place of an image when
the image fails to load on the visitor’s
screen. Alt text also works with screen
readers. It describes images to those site
visitors who are not able to see them.
Writing and testing alt text
When writing alt text, it is best practice to provide a short, concise phrase that clearly describes the content of the image.
If you wish to test your page for
accessibility, you may use a browser
extension such as Google Chrome Screen
Reader and listen to how the page
is read.
