Google DBM

Smart AdServer not visible as an SSP

As a buyer, if you cannot see Smart AdServer (as an SSP) in the Google DBM user interface, follow these instructions:

  • navigate to Partner
  • edit Partner
  • go to Exchanges
  • find SmartRTB
  • select checkbox
  • click Save

Hosting source

Problems may occur if the hosting source of the creative is a third party (e. g. Flashtalking)

Custom affinity targeting / affinity audiences

The buyer should not use custom affinity targeting / affinity audiences: one of the limitations of custom affinity targeting is that it can only be used on adx deals:

"Affinity audiences are currently only targetable on DoubleClick Ad Exchange inventory, so if your line item targets only affinity audiences, it will only buy from Ad Exchange. However, if your targeting includes an affinity segment and one or more first- or third-party audience lists in a logical OR relationship, your line item will still be able to purchase impressions from exchanges other than Ad Exchange."

User cookie lifetime

The lifetime of the user cookie (user matching) is 2 years.


  • through a deal, buyers challenge the network bid floor and the deal bid floor; thus, buyers need to bid higher than both of these bid floors in order to win the deal
  • no support of multi-size bid requests


  • no support of multi-impression bid requests; will be supported soon
  • no support of interstitial requests; will be supported soon
  • no support of the following sizes: 970x300, 990x90
