area-alt
WCAG 1.1.1 Non-text Content Level A
Who this affects
An image map region has no name, so its link is announced with no destination.
How to fix it
Add an alt attribute to each <area> describing where that region links to.
How much work is it?
Usually a content edit. That is a rough guide for planning, not an estimate for your codebase. A single content edit repeated across a template is a template change.
What a person still has to check
Passing this rule does not mean 1.1.1 passes. Automation checks part of the criterion, and the rest is a judgement:
Read each alt text and confirm it conveys what the image is for. Automation only checks that the attribute exists.

Where this check comes from
This is an axe-core rule. We run axe in a real browser on every page we scan. Deque’s reference for area-alt
Find out whether your site does this
A scan checks this rule on every page it visits, and shows you the code and a screenshot of each place it fires.
