Shopify product image alt text that actually helps shoppers
Describe what a shopper would learn from the photo: the product, its color or variant, the angle or detail shown, and anything visible that affects a buying decision. Keep most alt text under about 125 characters, skip phrases like image of, and leave purely decorative images with empty alt text.
Alt text is a sales tool, not paperwork
A screen reader user shopping your store cannot glance at a photo to check whether a bag has a top handle or whether a dress is midi or maxi length. Alt text carries that information, and missing or lazy alt text quietly removes products from their consideration.
Good alt text also disciplines your photography. If a photo cannot be described in a useful sentence, it may not be showing a shopper anything worth seeing either.
The formula that covers most product photos
Name the product, name the distinguishing feature in this specific photo, and stop. Front view of a linen shirt needs the color and fit. A close up needs the texture or hardware it is showing. A lifestyle photo needs the context that matters, like worn with the matching skirt.
Do not repeat the product title word for word for every image in a gallery. Five identical alt texts tell a screen reader user that five identical images exist, which is wasted time in a long product page.
Length, keywords, and what to leave out
Most alt text works between a short phrase and two short sentences. Long essays slow down browsing, because a screen reader reads them in full while the user is trying to move through a gallery.
Keywords belong only when they describe what is visible. Stuffing search terms into alt text makes it worse for the people it exists for and can look manipulative to search engines as well. Never start with image of or picture of; the screen reader already announces that it is an image.
Decorative images should say nothing
Swatches used purely as layout, background textures, and spacer graphics should have empty alt text so screen readers skip them. Forcing a description onto decoration adds noise between a shopper and the buy button.
The test is simple: if removing the image would lose no information, its alt text should be empty. If removing it would lose a detail a shopper needs, write that detail down.
A workflow your team will actually keep
Write alt text when you upload the product photos, not in a cleanup project months later. Add a line to your product setup checklist and a few good examples from your own catalog so new staff can copy the pattern.
Review alt text whenever photos change. Stores often update images for a new season and leave last year alt text describing colors and bundles that no longer exist, which is worse than a brief gap.
Frequently asked questions
Where do I add alt text in Shopify?
In the product editor, open each media item and use the Add alt text option, or edit it later from Files. Alt text set on the product media travels with that product page, which is where shoppers need it.
Should every product image have different alt text?
Yes, if the images show different things. Each photo earns its place by showing an angle, detail, or use case the others do not, and its alt text should name that difference.
Can alt text help my SEO?
It can help search engines understand an image and can surface products in image search, but that is a side effect. Write for the shopper first; keyword stuffed alt text reads badly and helps neither audience.
What about alt text for size charts and diagrams?
Those images carry dense information, so a short alt summary plus the same information as real text on the page is best. A screen reader user needs the measurements, not a description of the chart layout.
