How to fix images missing alt bulk on Shopify

Steps for Shopify

1. Go to Online Store → Themes → click 'Customize' on your active theme, OR click the three-dot menu → 'Edit code'.
2. In Edit Code, open the template most responsible for the issue: typically `sections/product-template.liquid` (or `sections/main-product.liquid` in Dawn-based themes) for product pages, or `sections/collection-template.liquid` / `sections/main-collection-product-grid.liquid` for collection grids.
3. Find every `<img>` tag and any `{% render 'image' %}` or `image_tag` Liquid filter call. For product images, ensure the alt attribute is set to `{{ image.alt | escape }}` with a fallback: `{{ image.alt | default: product.title | escape }}`.
4. For collection grids, the card snippet (e.g. `snippets/card-product.liquid`) is usually the single file to edit — update the `<img>` tag there to use `{{ card_product.featured_image.alt | default: card_product.title | escape }}`.
5. To set alt text on individual images without editing code: go to Content → Files (or Settings → Files) and click on an image to add alt text, OR on the Product page, click each product image thumbnail and enter alt text in the field that appears.
6. Save the file and preview a product/collection page to confirm `alt` attributes are populated.

What is images missing alt bulk?

Alt text (alternative text) is a short written description placed inside an image's HTML tag that explains what the image shows. When a page has dozens or hundreds of images missing alt text, it almost always means the root template — the product page layout, collection grid, or blog post design — is generating image tags without the `alt` attribute filled in. Fixing the template fixes every image it produces in one go, rather than editing each image individually.

Google explicitly uses alt text to understand image content and rank images in Google Images search — a meaningful source of free organic traffic for product-heavy stores. Pages where the majority of images have no alt text send a weak content signal to Google, which can suppress rankings for the entire page, not just the images. Beyond SEO, missing alt text is a WCAG 2.1 accessibility failure: screen-reader users — including those with visual impairments — cannot understand your product images at all, exposing your store to accessibility complaints and, in some jurisdictions, legal liability. Fixing this at the template level is a single change with store-wide impact across every page that template renders.
