A bid adjustment is modifying the set bids by a percentage based on factors such as location, device, time of the day, past website visitors and more. Bid adjustments modify the original bid to increase or decrease based on the relative performance of each factor to get a better ROI. The bid modifier adjustments are determined by performance across devices, locations, time of day and more. The performance metric will typically decided by conversion metrics such as the cost per conversion of a lead or sale.

The original bid is the average of all these factors- before making adjustments. Manual bidding can still be done, automated bidding rules or script bidding. Googles automatic bidding cannot be done at the same time as bid adjustments. Spending on individual clicks may vary as your bids increase or decrease according to the adjustments that are set.

Types of Bid Adjustments

Device bid adjustment

Adjust Mobile, tablets and desktop devices bids based on the relative performance of each. Bid lower for devices that are less profitable by adjusting base on a target metric like CPA, and higher for the best performing devices. It is also possible to just bid lower based on the percentage variation in performance- and not increase bids on the best performing keywords. In this case, standard bidding can be increased instead of the bid adjustment.
