It is determined that a particular user of network-based services has been presented or additionally has monetized a monetization opportunity (such as an advertisement) offered to the particular user via a computer network. Monetizing the monetization opportunity may include, for an advertisement, clicking on the advertisement such that money is made (typically at least in part by the service provider) as a result. Based on the determination, a monetization opportunity is caused to be referred, via the computer network, to at least one other user of the network-based services, other than the particular user, with whom the particular user has social ties. For example, the particular user may have a social tie with the at least one other user via network-based services, such as instant messaging. The social tie may be other than via network-based services, as well. |
