Abstract: A plurality of advertisements are associated with PPC (pay-per-click) payment amounts paid to third-party publishers for referrals. The PPC payment amount is based on a level of engagement for a particular user with a particular advertisement. As a result, each instance of an advertisement impression can lead to a varying PPC payment amount. The PPC payment amounts are accumulated by the publisher that successfully induces user interactions with the plurality of advertisements through a social media platform.
