ID 26. Maximize margin and pay for viewable impressions

This strategy will aim to maximize margin and buy a target volume of viewable impressions with the given maximum CPM. The target volume of impressions is calculated as advertiser budget / viewable CPM * 1000. This strategy is recommended if you want to buy as many viewable impressions as possible while maximizing margin and keeping the certain CPM threshold. It is usually used to maximize the impression viewability as cheaply as possible.

Budget Pacing


Budget Types



If no targeting restrictions are set, the strategy will buy the cheapest viewable inventory; this can negatively impact the inventory quality. We strongly recommend to use this buying strategy with inventory restrictions such as:

  • Traffic source lists, e.g. domains, URLs, app bundles

  • User segments uploaded to BidCore or collected by segment pixels

  • Specified supply sources, e.g. non-guaranteed deals

Strategy Settings

Advertiser budget

The total budget of the line item includes margin, extra fees, and media cost. This strategy will spend 100% of the budget during the specified flight dates with lifetime pacing. The budget will not be fully spent if some settings, e.g. CPM, margin, targetings are too strict, as there will not be enough inventory to purchase.

Maximum average CPM

The CPM in this strategy is an upper restriction for the optimization engine, i.e. the average CPM will never be higher than specified. As the strategy has lifetime pacing, it can buy inventory with a CPM higher than specified, but the final average CPM will b be equal or lower than specified.
