What is image redundant alt?

Every image on a web page can have an "alt" attribute — a short text description that screen readers announce aloud to blind or visually impaired shoppers. The "image-redundant-alt" issue means an image's alt text says exactly (or nearly) the same thing as visible text right next to it — for example, a product photo with alt="Red Running Shoes" placed directly beneath a heading that already reads "Red Running Shoes." Screen readers end up announcing the same phrase twice in a row, which is confusing and disorienting for shoppers who rely on them.

When screen reader users hear the same text repeated back-to-back, it wastes their time and creates a disjointed, unprofessional shopping experience — making them more likely to abandon your store. Accessibility failures like this can expose your business to legal risk under laws such as the ADA (US), the Equality Act (UK), and the European Accessibility Act (EU). Google's crawlers also read alt text: redundant, repetitive alt attributes are a low-quality signal that can dilute the value of your image SEO. Fixing this is a quick win that simultaneously improves the experience for assistive-technology users, reduces legal exposure, and keeps your image metadata clean for search engines.
