What is an XML feed?
An XML feed is a data file with information about your products. It contains a product’s name, description, price, terms of delivery, a category of the product and much more. This way it is distinguished from other items and classified to a category with the same products.
Feed address is unique to each online store. Often the address’ format looks like this: www.yourstore.com/feed.xml.
In case you don’t know your feed address, ask your online store’s supplier. He should be able to help you.
