Axe Core 4.8

Alternative text of images should not be repeated as text

When button and link text in an alt property value repeats, screen reader users hear the same information twice, rendering the alt text worthless and confusing.

It is redundant and potentially misleading to have alternate text for a link or image repeated in text adjacent to the link or image because a screen reader would read it twice.

Because image buttons employ alt attributes for labels, the labels should not repeat the text next to the button. Screen readers announce the text to the user twice when there is duplicate alternative text for an image or link in the text adjacent to that image or link.

What this Accessibility Rule Checks
