Shopify workflow
Shopify recommends brief, descriptive text and currently supports product-media editing from the product details screen.
Alt text is contextual. A useful description for one page may be redundant or misleading on another.
From examples to updates in your Shopify store
Lumi connects image descriptions to a controlled Shopify catalog workflow rather than treating every generated suggestion as ready to publish.
Start with the free report to sample storefront pages for missing or weak image alt text, missing meta descriptions, and page-structure findings.
Generate contextual drafts, then edit and publish the content that fits each product.
Apply approved Shopify updates, use generation history, and retain eligible-plan records of completed alt-text fixes.
Frequently asked questions
No. A photo can't prove a rating. Put verified ratings in the product description and describe visible features in the alt text.
Name the product and what it's doing in the scene, such as 'runner wearing a black hydration vest on a trail.' Keep scenery brief.
No. When gallery images show different angles, details, variants, packaging, or lifestyle context, the alt text should describe what is distinct about each image. A decorative or redundant image may instead need an empty alt attribute.
No. Useful alt text supports accessibility and helps search systems understand images, but the rest of your storefront matters too. Lumi uses Web Content Accessibility Guidelines (WCAG) as a reference without guaranteeing legal or ranking outcomes.
In Shopify Admin, open Products, choose a product, select a product media item, choose Add alt text, enter a brief description, and save. Shopify also supports alt text updates through product CSV workflows.
