How to fix images missing alt bulk on WooCommerce

Steps for WooCommerce

1. Navigate to Appearance → Theme Editor (or edit files via FTP/SSH). Locate `woocommerce/single-product/product-image.php` inside your child theme's WooCommerce overrides folder.
2. If the override does not exist, copy it from `wp-content/plugins/woocommerce/templates/single-product/product-image.php` into `wp-content/themes/YOUR-CHILD-THEME/woocommerce/single-product/product-image.php`.
3. Ensure `the_post_thumbnail` and `woocommerce_single_product_image_thumbnail_html` calls pass the alt text via the `$attr` array: `array('alt' => get_the_title())`.
4. For existing product images, go to Media Library, click each image → add alt text in the 'Alternative Text' field. For bulk editing, use a plugin such as 'SEO Bulk Image Alt Text' or 'Auto Image Alt Text' to generate alt text from product titles automatically.
5. For the shop/category grid, override `woocommerce/loop/loop-start.php` or check `content-product.php` to ensure `woocommerce_template_loop_product_thumbnail()` includes alt attributes.
6. Save and visit a product page; use browser DevTools to verify alt attributes on all images.

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.
