Shopify Alt Text in 2025: A Practical Guide

Product image alt text is easy to postpone until the catalog is large, inconsistent, and hard to clean up. For Shopify merchants, that creates practical problems: screen reader users get less useful product context, image SEO signals are weaker, and teams have no clear record of what changed.

This guide explains how to write better Shopify alt text, where merchants usually make mistakes, and how to build a reviewable workflow instead of relying on one-off edits.

What Shopify Product Alt Text Should Do

Alt text should describe the image in the context of the product page. It is not a place to repeat every keyword, shipping phrase, or promotion. A good product image description helps someone understand the visible product details that matter for buying decisions.

• Weak: "blue dress women fashion sale"
• Better: "Sleeveless navy linen midi dress with a square neckline and side pockets"

If the image shows a variant, mention the variant. If it shows texture, scale, material, packaging, or a lifestyle use case, describe the useful visual detail. If the image is decorative, it may need empty alt text instead of a forced description.

A Step-by-Step Shopify Alt Text Cleanup

1. Export or scan your catalog. Identify missing, duplicated, and placeholder alt text first.
2. Prioritize revenue pages. Start with best sellers, paid-search landing products, and high-impression collections.
3. Write for the image. Use visible attributes before adding product category terms.
4. Review before publishing. AI drafts can save time, but merchants should approve the final wording.
5. Keep a record. Document which products were updated, when, and by whom.

Common Mistakes

• Repeating the exact product title across every image.
• Stuffing search keywords into product image alt text.
• Using file names like IMG_2049.jpg as a substitute for descriptions.
• Publishing AI drafts without a merchant review step.
• Fixing one product at a time without tracking catalog-wide gaps.
