Find images with no alt text

Missing alt text removes a text description from the product gallery. Start with active products and check every image, including images added through a CSV import or a bulk media update.

  • Find active products with image media but no alt text.
  • Check newly imported products before a collection is promoted.
  • Separate decorative media from product images that need context.

Replace generic labels with visible details

Values such as ‘product image’ do not tell a shopper what the image shows. Name the product, then add visible color, material, angle, or use details that support the buying decision.

  • Describe the product and the most useful visible detail.
  • Skip ‘image of’ and ‘picture of’ when those words add no context.
  • Do not insert unrelated keywords into an image description.

Give each gallery image its own context

A gallery often shows different angles, colors, details, or usage scenes. Reusing one alt text value across every image hides those differences from people using assistive technology.

  • Describe the front, detail, packaging, or lifestyle view accurately.
  • Add variant details when the image visibly shows them.
  • Keep repeated alt text as a review signal, not an automatic error for every gallery.

Use a concise length target

Shopify recommends brief, descriptive alt text, with 125 characters or less as a practical recommendation and 512 characters as the maximum in its documentation. Shorter is useful when it still describes the visible product context.

  • Write the shortest description that preserves the important visual fact.
  • Remove repeated product names and filler phrases.
  • Review long descriptions for hidden marketing copy or keyword blocks.

Re-scan after media changes

Alt text gaps often return after a new supplier feed, CSV import, product replacement, or theme migration. Re-scan the catalog after the change and keep the approved wording in the audit trail.

  • Compare coverage before and after the media update.
  • Review AI suggestions before applying them to product media.
  • Sample live pages so the text matches the visible image.

Frequently asked questions

How do I audit Shopify product image alt text?

Find missing, generic, repeated, and overly long values, then review each image against its alt text. Prioritize active products and galleries changed by imports or theme updates.
