Check 7 / 19 LOW impact In the full checklist
Alt text descriptive: blue-linen-dress-front.jpg
What this check is
Alt text is what a screen reader announces and what search engines read when an image fails to load. "IMG_1234" wastes both.
How to implement it
Describe the product and the view in the alt text, as in the product name plus colour plus angle, and keep it under a short sentence. Decorative images take an empty alt, and the same file should not carry twenty different descriptions across pages.
How to verify it
Navigate the product page with a screen reader or an accessibility audit tool and confirm every meaningful image is announced with a description that identifies the product and view.
