See every featureAltGenius writes alt text for your product images from a template you choose, using details such as title, type, brand and variant. You see the result on your own products before you start. By default it fills in only images with no alt text, so anything you wrote stays as it is. Alt text with links or embed code, which review and video apps use, is skipped.
