Avoid Redundant Alternative Text

Images and related text are often paired together, such as a product image with the product name immediately below it, or a photograph with a caption. In instances where the text conveys the content of the image, the image should usually be given null or empty alternative text (alt=””). This avoids the redundancy of having a screen reader read the same information twice (once for the image alternative text and once for the caption or adjacent text).

If the image and the adjacent text are links to the same location, combine both the image and the text into one link and give the image null alternative text. This avoids redundancy, results in fewer links for the user to navigate, and results in fewer links for the user to navigate.
