Techniques for facilitating retargeting of content are described. According to various embodiments, a user specification of a first set of content items and a second set of content items may be received. Moreover, a user specification of flow logic information may be received. The flow logic information may specify a user trigger action, and an instruction that a second content item in the second set is only to be displayed to a particular user after it is determined that the particular user has performed the user trigger action on the first content item. Thereafter, it may be determined that the particular user has performed the user trigger action on the first content item, and the second content item may be displayed to the particular user, based on the flow logic information.
