From time to time it may be useful to suppress one or more products from ALL catalog feeds. In general, we recommend the use of catalog segments in Facebook to create ads that utilize only a subset of all products in the feed.
​
However, if you need to take a product out of an existing set that already has DPA ads running, you will want to use the suppress feature: You just need to the tag rr_track_exclude or pp_exclude to any products you want to exclude from the feed.
