The Filtering Option is able to read all product data that has been uploaded to a given advertiser. Further, advertisers can then filter out products from this product pool in which they do not want included in certain campaigns. This allows advertisers to upload product feeds once and filter out product information according to campaign objectives. Filtering Options eliminates the need to upload products every time a campaign is created.
For example, to display products that cost less than $50, use the “max price” Filter Option. This filters out all products above $50. These filters can be applied to all types of advertisers: retail, auto, and real-estate.
