Claim:
One or more computer-readable storage media storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising: receiving a first request for an advertisement of an advertiser; determining if a user associated with the first request is recognized by determining if the first request was accompanied by an identifier associated with a valid user account of the user associated with the first request; based at least in part on determining that the user associated with the first request is recognized, examining the valid user account to determine a purchase history for the user associated with the first request; providing an advertisement of an advertiser in response to the first request; generating an advertising fee to be paid by the advertiser in response to a user selection of the advertisement by the user associated with the first request, the advertising fee based at least in part on the purchase history of the user associated with the first request, an amount of the advertising fee corresponding to an amount of purchase history content of the user associated with the first request, and the purchase history comprising purchases previously made by the user associated with the first request before the user selection of the advertisement; receiving a second request for an advertisement of an advertiser; determining if a user associated with the second request is recognized by determining if the second request was accompanied by an identifier associated with a valid user account of the user associated with the second request; providing an advertisement of an advertiser in response to the second request; and based at least in part on determining that the user associated with the second request is not recognized, refraining from generating an advertising fee to be paid by the advertiser in response to a user selection of the advertisement by the user associated with the second request.
