CPA target and bid adjustements

By combining CPA target and the Data Driven Attribution model, would you still work on bid adjustment by day, hours of day, mobile, demographic?


CPA target whith its machine learning system is supposed to capture already all the signal described above plus many more, so apparently there is no need to work on bid adjustments. 


What are your thoughts?

Hi @Alessandro B,


with automated bidding strategy, you are restricted to use bid adjustments expect few cases.


  • If your campaign is using an automated bid strategy other than Maximize Clicks, it's not possible to set ad scheduling bid adjustments.
  • For Target CPA, device bid adjustments change your CPA target, rather than your bid.
  • For Target ROAS, the only device bid adjustment that can be used is -100%
