Campaign and ad group-level bid adjustments give you more control over your bids in Google Ads campaigns, providing the option to increase or decrease bids for different types of criteria.
Within the Google Ads API, campaign-level adjustments are accessible using
CampaignBidModifierService
and ad group-level adjustments are accessible using
AdGroupBidModifierService
.
Add, update, and remove bid adjustments
Use the create
, update
or remove
fields of
CampaignBidModifierOperation
or
AdGroupBidModifierOperation
operations to add, amend or remove bid adjustments.
This example demonstrates how to add a new ad group-level mobile bid adjustment:
Java
private void runExample( GoogleAdsClient googleAdsClient, long customerId, long adGroupId, double bidModifier) { // Creates an ad group bid modifier for mobile devices with the specified ad group ID and // bid modifier value. AdGroupBidModifier adGroupBidModifier = AdGroupBidModifier.newBuilder() .setAdGroup(ResourceNames.adGroup(customerId, adGroupId)) .setBidModifier(bidModifier) .setDevice(DeviceInfo.newBuilder().setType(Device.MOBILE)) .build(); // Creates an ad group bid modifier operation for creating an ad group bid modifier. AdGroupBidModifierOperation adGroupBidModifierOperation = AdGroupBidModifierOperation.newBuilder().setCreate(adGroupBidModifier).build(); // Issues a mutate request to add the ad group bid modifier. try (AdGroupBidModifierServiceClient adGroupBidModifierServiceClient = googleAdsClient.getLatestVersion().createAdGroupBidModifierServiceClient()) { MutateAdGroupBidModifiersResponse response = adGroupBidModifierServiceClient.mutateAdGroupBidModifiers( Long.toString(customerId), ImmutableList.of(adGroupBidModifierOperation)); System.out.printf("Added %d ad group bid modifiers:%n", response.getResultsCount()); for (MutateAdGroupBidModifierResult mutateAdGroupBidModifierResult : response.getResultsList()) { System.out.printf("\t%s%n", mutateAdGroupBidModifierResult.getResourceName()); } } }
C#
public void Run(GoogleAdsClient client, long customerId, long adGroupId, double bidModifierValue) { // Get the AdGroupBidModifierService. AdGroupBidModifierServiceClient adGroupBidModifierService = client.GetService(Services.V17.AdGroupBidModifierService); // Creates an ad group bid modifier for mobile devices with the specified ad group // ID and bid modifier value. AdGroupBidModifier adGroupBidModifier = new AdGroupBidModifier() { AdGroup = ResourceNames.AdGroup(customerId, adGroupId), BidModifier = bidModifierValue, Device = new DeviceInfo() { Type = Device.Mobile } }; // Creates an ad group bid modifier operation for creating an ad group bid modifier. AdGroupBidModifierOperation adGroupBidModifierOperation = new AdGroupBidModifierOperation() { Create = adGroupBidModifier }; // Send the operation in a mutate request. try { MutateAdGroupBidModifiersResponse response = adGroupBidModifierService.MutateAdGroupBidModifiers(customerId.ToString(), new AdGroupBidModifierOperation[] { adGroupBidModifierOperation }); Console.WriteLine("Added {0} ad group bid modifiers:", response.Results.Count); foreach (MutateAdGroupBidModifierResult result in response.Results) { Console.WriteLine($"\t{result.ResourceName}"); } } catch (GoogleAdsException e) { Console.WriteLine("Failure:"); Console.WriteLine($"Message: {e.Message}"); Console.WriteLine($"Failure: {e.Failure}"); Console.WriteLine($"Request ID: {e.RequestId}"); throw; } }
PHP
public static function runExample( GoogleAdsClient $googleAdsClient, int $customerId, int $adGroupId, float $bidModifierValue ) { // Creates an ad group bid modifier for mobile devices with the specified ad group ID and // bid modifier value. $adGroupBidModifier = new AdGroupBidModifier([ 'ad_group' => ResourceNames::forAdGroup($customerId, $adGroupId), 'bid_modifier' => $bidModifierValue, 'device' => new DeviceInfo(['type' => Device::MOBILE]) ]); // Creates an ad group bid modifier operation for creating an ad group bid modifier. $adGroupBidModifierOperation = new AdGroupBidModifierOperation(); $adGroupBidModifierOperation->setCreate($adGroupBidModifier); // Issues a mutate request to add the ad group bid modifier. $adGroupBidModifierServiceClient = $googleAdsClient->getAdGroupBidModifierServiceClient(); $response = $adGroupBidModifierServiceClient->mutateAdGroupBidModifiers( MutateAdGroupBidModifiersRequest::build($customerId, [$adGroupBidModifierOperation]) ); printf("Added %d ad group bid modifier:%s", $response->getResults()->count(), PHP_EOL); foreach ($response->getResults() as $addedAdGroupBidModifier) { /** @var AdGroupBidModifier $addedAdGroupBidModifier */ print $addedAdGroupBidModifier->getResourceName() . PHP_EOL; } }

Retrieve bid adjustments
You can retrieve existing campaign-level bid adjustments by looking for all the
campaign_bid_modifier
values. At the ad
group level, search for
ad_group_bid_modifier
.
Here is a GAQL query that retrieves all bid modifiers of the account that are
related to a given ad group:
SELECT campaign.id, ad_group.id, ad_group_bid_modifier.bid_modifier, ad_group_bid_modifier.criterion_id FROM ad_group_bid_modifier WHERE ad_group.id = ad_group_id
