Adjust Bids with Bid Modifiers

You can use the Google Ads API to set bid adjustments (also called bid modifiers) for Hotel ads. For details about the bid adjustments that you can set, see About bid adjustments for Hotel ads.

Campaign level bid adjustments

To use the Google Ads API to set bid adjustments at the campaign level, see Manage bid modifiers.

Ad group level bid adjustments

To use the Google Ads API to set bid adjustments at the ad group level, you need to first create an object of the relevant class (for example, HotelAdvanceBookingWindowInfo or HotelDateSelectionTypeInfo) and then set its fields to appropriate values.

For instance, if you want to create an ad group bid modifier using an advanced booking window between 30 and 60 days, you need to create a HotelAdvanceBookingWindowInfo object and set min_days to 30 and max_days to 60.

Finally, associate the relevant object to an AdGroupBidModifier object. You also have to specify the resource name of an ad group to which the ad group bid modifier belongs by using ad_group.
