Smart CPM is a custom pricing model of ExoClick which allows you to bid for at the best price possible. Rather than setting what you are going to pay for each 1000 impressions you will get.
In Smart CPM you set up the maximum you are willing to pay, and the system will determine the cost based on the minimum price for that Geo/device and the top CPM that is running in that target at the moment.
The system determines the lowest price you must pay to get the best position in the rotation of the campaigns up until your maximum bid price. For example:
If the top bid is 0.4 cents, and you set up a Smart CPM campaign of 0.7 cents, then you will become the top bidder and get more of the traffic. You will only pay what is needed to keep you in the top position, rather than the price you have set in the campaign. You will stay in that top position until another advertiser matches or outbids 0.7 cents, then you will start getting less traffic.
Used wisely, Smart CPM can save you time and guarantee the best visibility at the most affordable price. You can see a clear example of effective Smart CPM usage from one of our clients in this link:
Note: Be realistic with your budgets as targeting too many impressions with a large bid price and a very small budget will increase the chances of an overspend!
