Page Summary
-
Location targeting allows you to serve ads to users in specific geographical areas, preventing wasted ad spend in irrelevant regions and enabling direct targeting of local customers.
-
Geo targeting campaigns for a region can be done using a Criterion ID, which uniquely identifies each targetable location and can be looked up using
GeoTargetConstantService.SuggestGeoTargetConstants. -
You can also look up location criterion IDs by location name using
GeoTargetConstantService.SuggestGeoTargetConstants. -
Proximity targeting allows you to target areas within a specified radius of a specific geographical point using a
ProximityInfoobject. -
Geo targets can be retrieved using
GoogleAdsService.SearchStream, updated by comparing existing and new targets, and excluded by setting thenegativefield totrueforLocationInfoobjects.
This guide describes location targeting, and how you can use the Google Ads API to add, retrieve, and update location targeting for your campaigns.
For information about targeting limits, see the Targeting Limits section of About Google Ads account limits.
Why is geo-targeting important?
Location targeting lets you serve ads to users in a particular geographical region. For example, assume you're advertising for a chain of supermarkets. Without location targeting, your ads would show in all regions worldwide, and your ads might receive clicks from users in regions where you have no supermarket locations. This generates cost while providing no possibility of a return on the investment. With location targeting, your campaigns show ads only in regions where you have open supermarkets. This approach also lets you directly target customers searching locally for supermarkets.
The Google Ads API lets you target your ads by country, region, or proximity around a specific geographical point.
Geo-target campaigns for a region
You can target campaigns to any geographical region for which Google Ads
supports location targeting, such as a country, a state, a city, or a postal
region. Each targetable location is uniquely identified by a Criterion ID. You
can look up a criterion ID using
GeoTargetConstantService.SuggestGeoTargetConstants.
The resource_name of each GeoTargetConstant is of the
form geoTargetConstants/{Criterion ID}. For example, the resource_name value
of New York state is geoTargetConstants/21167.
You can add geo targets to your campaigns using the
CampaignCriterionService (or at the ad group
level using AdGroupCriterion for supported campaign
types, such as Demand Gen campaigns with upgraded_targeting enabled). The
following code snippet shows how to target your campaign with a criterion ID.
Java
private static CampaignCriterion buildLocationIdCriterion( long locationId, String campaignResourceName) { Builder criterionBuilder = CampaignCriterion.newBuilder().setCampaign(campaignResourceName); criterionBuilder .getLocationBuilder() .setGeoTargetConstant(ResourceNames.geoTargetConstant(locationId)); return criterionBuilder.build(); }
C#
private CampaignCriterion buildLocationCriterion(long locationId, string campaignResourceName) { GeoTargetConstantName location = new GeoTargetConstantName(locationId.ToString()); return new CampaignCriterion() { Campaign = campaignResourceName, Location = new LocationInfo() { GeoTargetConstant = location.ToString() } }; }
PHP
private static function createLocationCampaignCriterionOperation( int $locationId, string $campaignResourceName ) { // Constructs a campaign criterion for the specified campaign ID using the specified // location ID. $campaignCriterion = new CampaignCriterion([ // Creates a location using the specified location ID. 'location' => new LocationInfo([ // Besides using location ID, you can also search by location names using // GeoTargetConstantServiceClient::suggestGeoTargetConstants() and directly // apply GeoTargetConstant::$resourceName here. An example can be found // in GetGeoTargetConstantByNames.php. 'geo_target_constant' => ResourceNames::forGeoTargetConstant($locationId) ]), 'campaign' => $campaignResourceName ]); return new CampaignCriterionOperation(['create' => $campaignCriterion]); }

Google may occasionally phase out some location criteria for various reasons:
the location may be restructured into smaller or larger areas, geo-political
changes, and so forth. Refer to the status field of a
GeoTargetConstant object to determine if a location is
ENABLED or REMOVAL_PLANNED.
Look up by location name
You can also look up the criterion ID by location name using
GeoTargetConstantService.SuggestGeoTargetConstants.
The following code example shows how to look up a location criterion ID by
location name.

Target campaigns for proximity to a location
There are times when you might want to target even more precisely than a city or
country. For example, you may want to advertise your supermarkets within 10
kilometers of your shop location. In such cases, you can use
proximity targeting. The code to create a proximity
target is similar to adding a location target, except that you have to create a
ProximityInfo object instead of a
LocationInfo object.
Java
private static CampaignCriterion buildProximityLocation(String campaignResourceName) { Builder builder = CampaignCriterion.newBuilder().setCampaign(campaignResourceName); ProximityInfo.Builder proximityBuilder = builder.getProximityBuilder(); proximityBuilder.setRadius(10.0).setRadiusUnits(ProximityRadiusUnits.MILES); AddressInfo.Builder addressBuilder = proximityBuilder.getAddressBuilder(); addressBuilder .setStreetAddress("38 avenue de l'Opéra") .setCityName("Paris") .setPostalCode("75002") .setCountryCode("FR"); return builder.build(); }
C#
private CampaignCriterion buildProximityCriterion(string campaignResourceName) { ProximityInfo proximity = new ProximityInfo() { Address = new AddressInfo() { StreetAddress = "38 avenue de l'Opéra", CityName = "Paris", PostalCode = "75002", CountryCode = "FR" }, Radius = 10d, // Default is kilometers. RadiusUnits = ProximityRadiusUnits.Miles }; return new CampaignCriterion() { Campaign = campaignResourceName, Proximity = proximity }; }
PHP
private static function createProximityCampaignCriterionOperation(string $campaignResourceName) { // Constructs a campaign criterion as a proximity. $campaignCriterion = new CampaignCriterion([ 'proximity' => new ProximityInfo([ 'address' => new AddressInfo([ 'street_address' => '38 avenue de l\'Opéra', 'city_name' => 'Paris', 'postal_code' => '75002', 'country_code' => 'FR', ]), 'radius' => 10.0, // Default is kilometers. 'radius_units' => ProximityRadiusUnits::MILES ]), 'campaign' => $campaignResourceName ]); return new CampaignCriterionOperation(['create' => $campaignCriterion]); }
Python
def create_proximity_op( client: GoogleAdsClient, customer_id: str, campaign_id: str ) -> CampaignCriterionOperation: campaign_service: CampaignServiceClient = client.get_service( "CampaignService" ) # Create the campaign criterion. campaign_criterion_operation: CampaignCriterionOperation = client.get_type( "CampaignCriterionOperation" ) campaign_criterion: CampaignCriterion = campaign_criterion_operation.create campaign_criterion.campaign = campaign_service.campaign_path( customer_id, campaign_id ) campaign_criterion.proximity.address.street_address = "38 avenue de l'Opera" campaign_criterion.proximity.address.city_name = "Paris" campaign_criterion.proximity.address.postal_code = "75002" campaign_criterion.proximity.address.country_code = "FR" campaign_criterion.proximity.radius = 10 # Default is kilometers. campaign_criterion.proximity.radius_units = ( client.enums.ProximityRadiusUnitsEnum.MILES ) return campaign_criterion_operation

Retrieve geo-targets
You can retrieve the geo targets for a campaign using
GoogleAdsService.SearchStream. Including
campaign_criterion.type and campaign_criterion.resource_name in the SELECT
clause lets you distinguish between LOCATION and PROXIMITY criteria and
record the resource names for subsequent updates or removals.
SELECT
campaign_criterion.resource_name,
campaign_criterion.campaign,
campaign_criterion.type,
campaign_criterion.location.geo_target_constant,
campaign_criterion.proximity.geo_point.longitude_in_micro_degrees,
campaign_criterion.proximity.geo_point.latitude_in_micro_degrees,
campaign_criterion.proximity.radius,
campaign_criterion.proximity.radius_units,
campaign_criterion.proximity.address.street_address,
campaign_criterion.proximity.address.city_name,
campaign_criterion.proximity.address.postal_code,
campaign_criterion.proximity.address.country_code,
campaign_criterion.negative
FROM campaign_criterion
WHERE
campaign_criterion.campaign = 'customers/{customer_id}/campaigns/{campaign_id}'
AND campaign_criterion.type IN ('LOCATION', 'PROXIMITY')
Update geo-targets
Location criteria on a campaign are immutable after creation, so updating a
campaign's geo targets requires replacing obsolete targets with new ones in a
single atomic
CampaignCriterionService.MutateCampaignCriteria
request:
- Query the campaign's existing
LOCATIONandPROXIMITYcriteria using the GAQL query in Retrieve geo-targets. - Compare the existing criteria with your intended target list.
- For each obsolete criterion, build a
CampaignCriterionOperationwithremoveset to the existing criterion'sresource_name. - For each new location or proximity target, build a
CampaignCriterionOperationwithcreatepopulated with the newLocationInfoorProximityInfocriterion. - Pass both the
removeandcreateoperations in a singleMutateCampaignCriteriacall so the transition happens atomically.
Exclude geo-targets
You can also exclude LocationInfo, but not
ProximityInfo. This feature is most useful if you want to
target a region, but exclude a sub-region (for example, to target the entire
United States, except for New York City). To exclude a region, set the
negative field in
CampaignCriterion to true.
Target multiple geographic regions
If you use a LocationGroupInfo, you can enable a
campaign to target multiple geographic regions centered on locations defined by
location assets or filtered by a geographic region:
- Location asset sets: Set either
enable_customer_level_location_asset_set = true(to target the customer's location asset set) orlocation_group_asset_sets(to target specificAssetSetresource names). These two fields cannot be set together, and neither can be combined withgeo_target_constants. - Radius and units: The radius on
LocationGroupInfodefines a circular region around each location and requires bothradiusandradius_units(LocationGroupRadiusUnitsEnum):- When using location asset sets
(
enable_customer_level_location_asset_setorlocation_group_asset_sets), supportedradius_unitsvalues areMILLI_MILESandMETERS. - When filtering by
geo_target_constants(where at most one criterion ID is allowed, andAssetSetfields are not set), supportedradius_unitsvalues areMILESandMETERS.
- When using location asset sets
(
Advanced location options with GeoTargetTypeSetting
Beyond specifying locations to target or exclude, you can refine how Google Ads
matches users to these locations using advanced location options. These settings
are managed through Campaign.GeoTargetTypeSetting.
This setting consists of two fields:
positive_geo_target_type: Determines how users are matched for locations you target.negative_geo_target_type: Determines how users are matched for locations you exclude.
Positive targeting settings (positive_geo_target_type)
You can choose from the following options for your positive location targeting,
using values from the PositiveGeoTargetTypeEnum:
PRESENCE_OR_INTEREST(Recommended default):- Reaches people who are likely to be in, or regularly in, your targeted locations, plus people who have shown interest in your targeted locations.
- Interest can be signaled by search terms, past visits, or content consumed related to the location.
- This option provides the broadest reach.
PRESENCE:- Reaches only people who are likely to be physically located or regularly in your targeted locations.
- This is more restrictive and useful if your services or products are strictly limited to people physically present in an area.
Negative targeting settings (negative_geo_target_type)
For locations you want to exclude, you use the
NegativeGeoTargetTypeEnum:
PRESENCE(Recommended default):- Excludes people who are likely to be physically located in the locations you've excluded.
- People outside the excluded areas, even if interested in them, may still see your ads, provided they match your positive targeting.
Manage advanced location options
You can control these settings by updating the
Campaign.geo_target_type_setting object. The following example shows the
structure of a CampaignOperation update that sets positive_geo_target_type
to PRESENCE:
// Conceptual structure for a Campaign update operation
operations {
update {
resource_name: "customers/{customer_id}/campaigns/{campaign_id}"
geo_target_type_setting {
positive_geo_target_type: PRESENCE
// negative_geo_target_type remains at its default PRESENCE
}
}
update_mask {
paths: "geo_target_type_setting.positive_geo_target_type"
}
}
To fetch the current settings, include
campaign.geo_target_type_setting.positive_geo_target_type and
campaign.geo_target_type_setting.negative_geo_target_type in your
GoogleAdsService search query.
By configuring these settings, you gain more granular control over who sees your ads based on their relationship to the geographic locations you've specified, aligning more closely with your business goals.
Best practices
- Choose
PRESENCEif your product or service is strictly limited to people physically present in a location. For example, suppose you require users to be in-store or require local delivery. - Choose
PRESENCE_OR_INTERESTif your product or service can also benefit people interested in a location, even if not physically present. For example, a user planning a vacation might be interested in hotels in their destination city. - Use negative location targeting to refine reach. If you target the US
with
PRESENCE_OR_INTEREST, but don't ship to a specific state, you can exclude that state usingnegative=trueon aLocationInfocriterion. Combined withnegative_geo_target_typeset toPRESENCE, this prevents your ads from showing to users in that state, while still reaching users outside that state who might be interested in US locations.
What's next
- Adjust bids by criterion in the Bid modifiers guide.
