An exemplary system includes a publisher subsystem configured to communicate with an access device and an advertiser device over a data communication network. The publisher subsystem includes a publish module, a session module, and an allocation module. The publish module is configured to publish content over the data communication network, the content including an advertisement. The session module is configured to detect a selection of the advertisement, initiate a session between the access device and the advertiser device in response to the selection, the advertiser device being associated with the advertisement, and receive feedback from the advertiser device. The allocation module is configured to allocate revenue based on the feedback. In some examples, the amount of the revenue is independent of the feedback.
