Text of buttons and links should not be repeated in the image alternative
Log in (Premium content) Request a demo
When button and link text is repeated in an
<alt> attribute value, screen reader users will hear the same information twice, which renders the alt text meaningless and confusing.
Why this is Important
It is unnecessary and potentially confusing to have alt text for a link or image to be repeated in the text adjacent to the link or image, since it would be read twice by a screen reader.
How to Fix the Problem
Ensure that for any <a href> or <img> element with an alt text value that is repeated as the text adjacent to the element, this redundancy is eliminated.
