本指南將說明指定地區，以及如何使用 Google Ads API 新增、擷取及更新廣告活動的指定地區。
指定地理區域的重要性
指定地區可讓您向特定地理區域的使用者放送廣告。舉例來說，假設您要為連鎖超市放送廣告。 如果沒有指定地區，您的廣告就會在全球所有區域放送，而在您沒有超市位置的區域使用者，廣告可能會獲得點擊。這樣會產生成本，卻沒有產生投資報酬率的可能性。使用指定地區時，廣告活動就只會在您營業的超市區域顯示廣告。並直接指定搜尋當地超市的客戶。
Google Ads API 可讓您按國家/地區、區域或特定地理位置的鄰近區域指定廣告。
進一步瞭解如何指定在特定地理區域刊登廣告。
指定地理區域的廣告活動
您可以將廣告活動指定至 Google Ads 支援指定地區的任何地理區域，例如國家/地區、州/省、城市或郵遞區號區域。每個可指定的地區都用一組條件 ID 來識別。您可以使用 GeoTargetConstantService.SuggestGeoTargetConstants 查詢條件 ID。每個 GeoTargetConstant 的 resource_name 都是 geoTargetConstants/{Criterion ID} 的形式。舉例來說，紐約州的 resource_name 值為 geoTargetConstants/21167。
您可以使用 CampaignCriterionService，在廣告活動中加入指定地理區域。下列程式碼片段說明如何使用條件 ID 指定廣告活動。
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]);
}

campaign_criterion_operation = client.get_type("CampaignCriterionOperation")
campaign_criterion = campaign_criterion_operation.create
campaign_criterion.campaign = campaign_service.campaign_path(

Google 有時會基於各種原因，逐步淘汰部分位置條件：該地點可能會以較小或較大區域進行建構、地理區域政治變更等。請參閱 GeoTargetConstant 物件的 status 欄位，判斷位置是 ENABLED 或 REMOVAL_PLANNED。如想進一步瞭解指定地區的淘汰方式，請參閱這篇文章。
依地區名稱查詢
您也可以使用 GeoTargetConstantService.SuggestGeoTargetConstants，按地區名稱查詢條件 ID。以下程式碼範例顯示如何按地區名稱查詢地點條件 ID。
Java
private void runExample(GoogleAdsClient googleAdsClient) {
try (GeoTargetConstantServiceClient geoTargetClient =
googleAdsClient.getLatestVersion().createGeoTargetConstantServiceClient()) {
SuggestGeoTargetConstantsRequest.Builder requestBuilder =
SuggestGeoTargetConstantsRequest.newBuilder();
// Locale is using ISO 639-1 format. If an invalid locale is given, 'en' is used by default.
requestBuilder.setLocale("en");
// A list of country codes can be referenced here:
// https://developers.google.com/google-ads/api/reference/data/geotargets
requestBuilder.setCountryCode("FR");
requestBuilder
.getLocationNamesBuilder()
.addAllNames(ImmutableList.of("Paris", "Quebec", "Spain", "Deutschland"));
SuggestGeoTargetConstantsResponse response =
geoTargetClient.suggestGeoTargetConstants(requestBuilder.build());
for (GeoTargetConstantSuggestion suggestion :
response.getGeoTargetConstantSuggestionsList()) {
System.out.printf(
"%s (%s,%s,%s,%s) is found in locale (%s) with reach (%d) for search term (%s).%n",

GeoTargetConstantServiceClient geoService =
client.GetService(Services.V16.GeoTargetConstantService);

LocationNames = new SuggestGeoTargetConstantsRequest.Types.LocationNames()
};
request.LocationNames.Names.AddRange(locations);

指定特定地區鄰近使用者的廣告活動
有時候，您可能會想要比城市或國家/地區更精準地指定目標。舉例來說，您可能想在商店地點 10 公里以內的範圍內宣傳超市。在這種情況下，您可以使用指定鄰近目標。建立鄰近目標的程式碼與新增指定地區類似，只是您必須建立 ProximityInfo 物件，而非 LocationInfo 物件。
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, customer_id, campaign_id):
campaign_service = client.get_service("CampaignService")
# Create the campaign criterion.
campaign_criterion_operation = client.get_type("CampaignCriterionOperation")
campaign_criterion = 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"

end

end
end
end
Perl
sub create_proximity_campaign_criterion_operation {
my ($campaign_resource_name) = @_;
# Construct a campaign criterion as a proximity.
my $campaign_criterion =
Google::Ads::GoogleAds::V16::Resources::CampaignCriterion->new({
proximity => Google::Ads::GoogleAds::V16::Common::ProximityInfo->new({

}

});
return
Google::Ads::GoogleAds::V16::Services::CampaignCriterionService::CampaignCriterionOperation
->new({
create => $campaign_criterion
});
}
擷取指定地理區域
您可以使用 GoogleAdsService.SearchStream 擷取廣告活動的指定地理區域。您可以使用 WHERE 子句篩選結果。
SELECT
campaign_criterion.campaign,
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.negative
FROM campaign_criterion
WHERE
campaign_criterion.campaign = 'customers/{customer_id}/campaigns/{campaign_id}'
AND campaign_criterion.type IN (LOCATION, PROXIMITY)
更新指定地理區域
如要更新廣告活動的指定地區，您必須擷取現有指定地理區域的清單，並與新指定目標清單進行比較，接著，您可以使用 remove 作業來移除不需要的目標，再使用 create 作業新增需要的指定地理區域 (現有廣告活動缺少這些目標)。
排除指定地理區域
您也可以排除 LocationInfo，但不能排除 ProximityInfo。如果您想指定某個區域，但要排除某個子區域 (例如指定整個美國，但排除紐約市)，這項功能就非常實用。如要排除區域，請將 CampaignCriterion 中的 negative 欄位設為 true。
指定多個地理區域
只要使用 LocationGroupInfo，即可讓廣告活動指定多個地理區域。系統以廣告活動地點額外資訊所定義的地點為中心，
LocationGroupInfo 中定義的半徑代表每個位置周圍的一個圓形區域，當中包含 radius 物件、長度和 radius_units，兩者可以是公尺或英里 (LocationGroupRadiusUnitsEnum)。
可以按照 geo_target_constant 欄位中列出的指定地理區域條件 ID 清單，篩選 LocationGroupInfo 中的地點。如果已定義，則不會指定特定條件 ID「以外」的任何地點。
