Target CPM – What is it and does it increase ad revenue?

Reading time: 4 minutes

Online advertising has become one of the lucrative fields for experienced digital marketers. Stats show that there are 4.66 billion internet users globally and more than 2.14 billion online purchasers. If you’re new in this field or have a young online website, you may find it challenging to understand some of the concepts that apply in online promotions. One of the terminologies you’ll come across is the cost per mille (CPM). You need to understand various vital aspects of CPM, and the knowledge will assist you in delivering result-oriented online marketing campaigns.

What is target CPM (tCPM)?

Floor price enables publishers to create a minimum price for their ad spaces. If a bid comes up for an ad unit, it’s evaluated as per the floor price. For optimal fill rates, publishers steer away from creating high floor prices. And this may result in selling their inventory at a throw-away price, thus underutilizing the real potential of their list. Due to this dilemma, Google created Target CPM on their Ad Manager portal.

Target CPM (or tCPM) is a dynamically allocated floor price for an advertisement unit. The price can be higher or lower than the floor price set by the content creators. Google Ad Manager created tCPM to equalize the arriving bids actively and retain the target eCPM of the website owner.

How does target CPM influence the header auctions?

Header auction enables the simultaneous sale of ad inventory to direct and programmatic advertisers. The procedure happens in one unified auction rather than in a splintered manner. The advantage of this procedure is that every purchaser has the same opportunity to bid on the same ad space, which allows for enhanced competition between bidders. And this means improved revenues for publishers.

When running header auctions with a set target CPM for your ad spaces, you should communicate the floor prices to partners. In specific cases, price proposals from partners may be lower than tCPM, and ad servers may avoid them. Thus, the best strategy is to create corresponding floor prices for supply-side platforms taking part in your header auctions. You can achieve this through a header wrapper or SSP dashboards.

How to set up target CPM in Google Ad Manager?

If you’re a Google ad Manager (GAM) publisher, a target CPM feature is available for you on the platform. You can activate the feature when setting up price rules for your ad spaces. Currently, Google is moving from second-price auction to unified first-price arrangement, and two scenarios exist:

  • Open auction pricing rules.
  • Unified pricing rules (UPR).

Although Google has moved out of open auction pricing rules, the feature is still available for publishers.  According to Google, 3 per cent of Ad Exchange traffic will come with the second-price bid for a brief duration. And this is the reason sellers shouldn’t leave the visitors without any floor prices. So, here we explain how to create a target CPM through both pricing principles.
