There are different cost models used to settle accounts with a traffic source. These are Cost-per-mille (CPM), Cost-per-action (CPA), Cost-per-click (CPC), Revshare and an Auto option. 

Cost per click is a model of buying traffic from a traffic source, where you pay for every time a user clicks on an ad. In Voluum, CPC is fixed, meaning that you need to provide a cost value while creating campaign to properly track cost in Voluum. You can view the value you provided in the CPC column in Voluum. Take into consideration that the cost tracked by Voluum when using this cost model might differ from what you pay to your traffic source, if it uses the second price auction bidding model.

Cost per action is a model of buying traffic from a traffic source, where you pay for a single user action (such as purchase, app install, etc.). In Voluum, CPA is fixed, meaning that you need to provide a cost value while creating campaign to properly track cost in Voluum. You can view the value you provided in the CPA column in Voluum.

Cost per mille (thousand) is a cost model of buying traffic from a traffic source, where you pay for a thousand ad impressions. In Voluum, CPM is fixed, meaning that you need to provide a cost value while creating campaign to properly track cost in Voluum. The CPM does not depend on further user actions, like a click or a conversion. You need to properly set up impression tracking in order to accurately record impressions. You can view the value you provided in the CPM column in Voluum. Take into consideration that the cost tracked by Voluum when using this cost model might differ from what you pay to your traffic source, if it uses the second price auction bidding model. To learn on how to check how much you actually pay for thousand impressions, go to the eCPM entry.

Pixel redirect is used when you want to fire client-side conversion back to a traffic source that does not support a postback URL.

A click URL / multi-offer click URL is a link or set of links provided by Voluum that directs user from a landing page to an offer or offers. It must be pasted into the body section of a landing page HTML.

An affiliate network is a platform where offer owners and people who want to promote their offers meet. Affiliate networks aggregate multiple offers. In Voluum, the affiliate network element can also be used as a way of grouping different offers by given criteria, like verticals or creatives used.

Campaign is an element in Voluum that incorporates other elements to create a campaign funnel. Creating a campaign funnel requires adding and configuring different elements, such as: offers, landers, flows, traffic sources or affiliate networks. Some components are optional and not required for running the campaign.

Tracking impressions (i.e. displaying an ad to a user) requires an additional configuration in traffic source component setup. The impression tracking toggle has to be turned on and an impression pixel from the campaign component setup has to be copied and pasted in your traffic source's setup. Note that you traffic source has to support impression pixels.
