Setting up a Facebook feed is usually a one time process which is most often neither updated nor modified unless faced with some issues. The usual setup of the feed is to make sure that the mandatory fields are covered to run the ads. These fields usually include the id, availability, condition, description, image_link, link, title, price, gtin, mpn, or brand. While these are required to run dynamic product ads, there are some additional fields which can send more data and make your feed information rich. This additional information can be used for both your ads as well as your dynamic creatives. Let's take a look at some of those fields, which will add value and help you improve your performance.
