Vayu Auto Tag Products

Product tagging with simple rules: tags are added and removed as your products change, ready for automated collections, filters and marketing.

Install it from the Shopify App Store, or open it from Apps in your Shopify admin.

Auto tag products by stock, sale status, price, vendor, type, title, collection, variant options and metafields
Bulk tag existing products, with a preview of how many gain or lose tags
Remove tags when a product stops matching, e.g. take "new-arrival" off after 30 days
