Why WooCommerce Variation Images Often Lack Alt Text and How to Fix It

WooCommerce variable products assign a separate image to each variation, such as colour or size, and these images are stored as individual media attachments with blank alt text fields by default. Because variation images are frequently uploaded in bulk and bypass the Media Library screen, they rarely receive descriptive alt text during setup. Most SEO plugins and accessibility audits only check featured and gallery images, leaving variation photos undetected and untagged. A store with 200 variable products and five variations each could have 1,000 images invisible to Google Images and inaccessible to screen-reader users. Effective alt text for variation images should name the product alongside its specific attribute and a relevant visual detail, such as colour or material, rather than repeating a generic product title across all variants.
