What each format building block adds to Shopify product image alt text.
Component reference
- Shop Name — from Settings
- Product Title — Shopify product title
- Variant Name — variant title when relevant
- Variant SKU — SKU when relevant
- Product Tags — product tags as context/keywords
- Existing Alt Text — keep prior alt in the new string
- AI Generated — model-written description
- Custom text — fixed words you type
Always include AI Generated or another descriptive source so the image content is actually explained, not only branded.
