Google Device Bid Adjustment

Table of contents


Google currently supports Desktop Bid Adjustment and Tablet Bid Adjustment for campaigns and groups. In this article, we'll explain device bid adjustment for campaigns and groups. 

Platform Support

Device Bid Adjustment is supported for Desktop, Mobile, and Tablet devices. The operational bidding adjustment range is -90% through +900%, with 0% bid adjustment as a baseline for all devices. If a bid adjustment is set to  -50%, the bid will be reduced by a half, so a bid of $3.00 will be reduced to $1.50. If the bid adjustment is set to +300%, a bid of $3.00 will be increased by 4 times to $12.00.

  • Starting bid is $1.00
  • Adjustment is  -50%
  • Resulting bid is $1.00 +($1 x -50%) = $0.50


  • Starting bid is $1.00
  • Adjustment is +300%
  • Resulting bid is $1.00+($1x +300%) = $4.00

By setting a -100% device bid adjustment, you can effectively “turn-off” the campaign or group device. For example, if you set a mobile bid adjustment to -100% at the campaign-level, you will create a desktop/tablet-only campaign.

If you use device bid adjustments for both a campaign and its groups, the group-level bid adjustment will be used to determine device bid adjustment. But, if you set the campaign device bid adjustment to -100%, then the device adjustment at the group will not be used and the group device bid adjustment will be inherited as -100%. In Marin’s platform, if you set a campaign device bid adjustment to -100% and the group is set to another value, Google will respond with an error upon push to Google Ads.
