Auto-CPM automates CPM updating for non-bidding networks. This aligns the CPM price for a network placement ID in the MAX Dashboard with the network-reported CPM.

The CPM price updates daily according to the average network CPM for the last seven days. Auto-CPM supports ad unit/network placement/country granularity. The network ID must have at least 1,000 impressions in the last seven days to enable CPM updating in MAX.

Auto-CPM allows for fair competition between all networks in the unified auction because it uses accurate pricing. This also reduces the work of manually updating CPMs, which can lead to inaccurate or decreased revenue.

If you do not enable auto-CPM, MAX uses the CPM value that you enter manually.

Activating auto-CPM

To activate auto-CPM, follow these steps:

Manually add the network price floor for each network placement ID in the waterfall(s) on the Ad Unit page. It’s important that the MAX CPM price initially matches the network CPM floor or historical CPM. This avoids data discrepancies later.
Open the Networks page (MAX > Mediation > Manage > Networks). Connect the network that you want to mediate by entering its network API credentials.
Click the Connect button for the network that you want to activate. The Manage Network page appears. For non-bidding networks, you will see a toggle with which you can activate auto-CPM. Bidding networks submit real-time bid pricing and so they do not use auto-CPM.

The CPM price is grayed-out in the waterfall for any network placement IDs that auto-CPM governs. Click the info ⓘ button in the CPM price field to see options either to override auto-CPM by manually entering the CPM or to see a detailed breakdown of the CPM values used.

Ad Unit 1: $7, Include All. Ad Unit 2: $2, Exclude 5. + Add New Ad Unit button.

MAX applies heavier weighting to more recent data in its seven day look-back. This may cause adjusted CPM to not match the average CPM.

Networks are not eligible for auto-CPM if their reporting does not include ad unit/network ID/country granularity. Custom networks are also not eligible for auto-CPM.

To ensure that auto-CPM works with accurate data, use the network comparison report to check for CPM and revenue discrepancies on a weekly basis. If there are discrepancies greater than 5%, use the report to identify the affected network IDs, then contact your account team or submit a support ticket for help with troubleshooting.
