Every time you create a listing, it creates a “shadow copy” of that listing in Products. So each listing has assigned its own product in WooCommerce -> Products. This is created to handle payments for Booking, so when booking request is confirmed, it creates WooCommerce order for that product, and user is able to pay for it.
Those products are set to product type “Listeo Booking”, they are not visible on front-end, and not indexed by google.
