What is a feed?
A feed is a data file with information about your products. There are different types of feed file types, e.g. XML or CSV. 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 into a category with the same products.
The feed URL 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.
