Accessibility Checking for Large Sites

Rocket Validator integrates axe-core version 4.4, into an automated web site scanner.

Text of buttons and links should not be repeated in the image alternative

When button and link text repeats in a alt attribute value, screen reader users hear the same information twice, which renders the alt text meaningless and confusing.

It is unnecessary and potentially confusing to have alternative text for a link or image to be repeated in text adjacent to the link or image since it would be read twice by a screen reader.

Since image buttons use alt attributes for labels, the labels must not duplicate the text next to the button. Duplicated alternative text for an image or link in the text adjacent to that image or link results in screen readers announcing the text to the user twice.
