Google Shopping supports 5 custom labels whereas Bidbrain have an unlimited support of custom labels - go nuts! Custom labels are the absolute best way for you to control what you want to push through Bidbrain. If you for example have a sale going on, or if you have seasonal products that you want to push extra during sale season, let Bidbrain know that through custom lables. The push won't happen over night, but Bidbrain will quickly pick up those products with custom labels and create new bid clusters.
