One variation of a method for tracking placement of products in a store includes: accessing an image depicting a shelving structure in the store; reading a product identifier of a product from a shelf tag detected in the image; accessing a set of template features associated with the product identifier; based on the shelf tag detected in the image, locating a region in the first image depicting a slot on the shelving structure; confirming presence of a unit of the product in the slot in response to detecting features analogous to the set of template features in the region in the image; detecting absence of the product from the slot based on absence of features analogous to the set of template features in the region in the image; and in response to detecting absence of the product from the slot, generating a prompt to restock the slot.
