Image Alt Text That Repeats a Caption Word for Word
1.1.1 — Non-text Content
Scenario
Setting
A ticket marketplace's seat-selection map
What’s wrong
Redundant alt duplicating adjacent caption/link text, creating double announcements (fails the "equivalent purpose" intent and creates noise. F-adjacent).
Example
A tester reviewing a ticket marketplace's seat-selection map finds this: redundant alt duplicating adjacent caption/link text, creating double announcements (fails the "equivalent purpose" intent and creates noise. F-adjacent).
Why it matters
Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning. On a ticket marketplace's seat-selection map, that means they get no equivalent for the sound or picture content.
How to test
Check for double announcements: if an image's alt repeats text already in an adjacent caption or link, a screen reader announces the same content twice — set alt="" instead.
How to fix
Remove the duplicated alt (empty alt) when a caption or link text already conveys the same content.
Outcome
With the fix in place on a ticket marketplace's seat-selection map, they hear or read what the media conveys.
Who is affected
Blind and low-vision people using screen readers, and anyone who browses with images disabled, when icons or photos carry meaning.
