Abstract: Embodiments are disclosed for attributing user actions to an appropriate referrer. An example system may attribute behavior of a user in an advertiser application of the advertiser to the user's selection of a promotion link presented within a user experience provided by a publisher on a client device. The example system includes a logic machine, a storage machine, and instructions stored within the storage machine executable to receive user click traffic in response to the user selecting the promotion link. The instructions are further executable to generate a token including information relating to the user click traffic, cause the advertiser application to be opened in response to the user click traffic via one or more of an instruction or application identifier that includes the token, and selectively attribute one or more user actions to the user's selection of the promotion link.
