We’d love to know if anyone is experiencing the issues we’ve outlined below.
If you’re a Sovrn publisher who also has a DoubleClick for Publishers (DFP) account, and you’re running Prebid, a recent change to DFP may be resulting in DoubleClick Ad Exchange (ADX) winning impressions at a CPM lower than the winning bid from Prebid.
The issue comes up if you’re running Prebid with DFP and have DFP First Look enabled. Some publishers are reporting that ADX is winning as much as 50% of the time at a lower CPM if First Look is enabled.
Is anyone having this issue?
Luckily, we’ve found that un-enabling First Look rectifies this. We’ve outlined steps below to address it.
Follow these steps:
- Sign in to DFP.
- Click Admin - Global settings - All network settings.
- Under “linked accounts" look for the DoubleClick Ad Exchange section. If it reads, ‘Default for dynamic allocation’ in green below your account name, click the Edit icon to the right. If this does not apply to you, you either do not have a linked AdX account or you have already un-enabled First Look.
- Unselect the Default for dynamic allocation checkbox. This will prohibit AdX from bidding above prebid responses and require it to properly compete with those line items.
- Click Save.
We’re curious to hear if others are having this or similar issues - or even if you’re finding no issues with this at all - so please chime in with any feedback. It’s a big help for other publishers!
