A system is disclosed for a pay-per-action (PPA) advertising model. An advertiser reports actions and pays an advertising provider for each action that is reported. The payment may be based on the rate at which the actions are reported. The action rate may be updated based on each reported action, which may modify the payment for that action and may modify the payment for previous actions. A one-time premium may be charged to advertisers and a minimum action rate may be established to encourage advertisers to accurately report actions.
