Shopify's admin edits alt text one image at a time from the product's media. To cover a whole catalog, use a template that writes alt text from data you already have, such as "{title} - {variant}", applied only to images without alt text. Review a preview before saving, and keep the text short and factual.
Alt text describes an image for screen readers, and it's one of the few text signals attached to a product photo. AI agents and image search can read it. Missing alt text is one of the most common gaps in Shopify catalogs.
That's fine for a handful of products and slow for hundreds.
In Botfound's Fix rules, add the action Alt text from template. Placeholders are {title}, {variant}, {vendor}, {type} and {index}; the default is {title} - {variant}. Tick "only if empty" to keep alt text you've already written. The preview lists every image and its new text before anything changes, and a run can be undone.
Not if you apply it only to images with no alt text. In Botfound that's the "only if empty" option.
Describe the product accurately. Natural product and variant names already contain the words shoppers use.
