What is dCPM with a CPA in online affiliate marketing?

Dynamic cost per mille with a cost per action target. This model is the most effective and balanced both for the advertiser and the publisher. In this model the the advertiser continues to advertise as long as his eCPA is under his CPA goal, and the publisher decides to advertise as long as the CPM he receives is higher than the competing advertisers. This is why neither the CPM nor the eCPA in this model is fixed. The following example describes the decision making process:

Analysis: On day 1 the optimization process sees that the advertiser is protable and even has a margin as he pays $4 for a $5 worth leads. This usually means that by driving more trac, more leads can be obtained. On day 2, more leads have been obtained, advertising still paying under his target lead price. On day 3, even more traffic is being bought breaking the CPA limit of the advertiser. The optimization process decides to reduce trac for the campaign.

Analysis: The campaign maintains a good balance between the eCPA for the advertiser and the CPM for the publisher until day 40 where even at the price of $0.3 CPM the campaign is not eective anymore at an eCPA of $9. Publisher cannot decrease the price since other advertisers bid more and advertiser is not protable. The campaign is dropped.
