指定地區

本指南說明指定地區，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。

如要瞭解指定目標限制，請參閱「關於 Google Ads 帳戶相關限制」一文的「指定目標限制」一節。

為什麼地理區域指定很重要？

指定地區，就能向特定地理區域的使用者放送廣告。舉例來說，假設您要宣傳連鎖超市。 如果沒有指定地區，廣告就會在全球所有地區放送，且可能收到來自沒有超市據點地區的使用者點擊。這會產生費用，但無法提供投資報酬率。透過指定地區，廣告活動只會在有營業超市的區域顯示廣告。此外，您也可以直接指定在當地搜尋超市的顧客。

您可以使用 Google Ads API，依國家/地區、區域或特定地理位置附近的範圍指定廣告。

為特定區域指定地理區域廣告活動

您可以將廣告活動指定到 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。每個可指定地區都有專屬的條件 ID。您可以使用 GeoTargetConstantService.SuggestGeoTargetConstants 查閱條件 ID。每個 GeoTargetConstant 的 resource_name 形式為 geoTargetConstants/{Criterion ID}。舉例來說，紐約州的 resource_name 值為 geoTargetConstants/21167。

您可以使用 CampaignCriterionService 將指定地區新增至廣告活動 (或使用 AdGroupCriterion 在廣告群組層級新增，適用於支援的廣告活動類型，例如啟用 upgraded_targeting 的需求開發廣告活動)。以下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]);
}

Google 可能會基於各種原因，不時淘汰部分地點條件：地點可能會重組為較小或較大的區域、地緣政治變化等等。請參閱 GeoTargetConstant 物件的 status 欄位，判斷地點是否為 ENABLED 或 REMOVAL_PLANNED。

依位置名稱查詢

您也可以使用 GeoTargetConstantService.SuggestGeoTargetConstants，依據地點名稱查詢條件 ID。下列程式碼範例說明如何依據地點名稱查詢地點條件 ID。

Java

private void runExample(GoogleAdsClient googleAdsClient) {
  try (GeoTargetConstantServiceClient geoTargetClient =

    requestBuilder.setLocale("en");

    // A list of country codes can be referenced here:

指定廣告活動的鄰近地區

有時您可能需要比城市或國家/地區更精確的目標對象。舉例來說，你可能想在商店據點方圓 10 公里內宣傳超市。在這種情況下，您可以使用鄰近地區指定目標。建立鄰近地區目標的程式碼與新增地區目標類似，但您必須建立 ProximityInfo 物件，而不是 LocationInfo 物件。

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。在 SELECT 子句中加入 campaign_criterion.type 和 campaign_criterion.resource_name，即可區分 LOCATION 和 PROXIMITY 條件，並記錄資源名稱，以利後續更新或移除。

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')

更新指定地理區域

廣告活動的指定地區條件建立後就無法變更，因此如要更新廣告活動的指定地區，必須在單一原子CampaignCriterionService.MutateCampaignCriteria要求中，以新目標取代舊目標：

  1. 使用「擷取地理區域目標」中的 GAQL 查詢，查詢廣告活動現有的 LOCATION 和 PROXIMITY 條件。
  2. 比較現有條件與目標目標對象名單。
  3. 針對每個已淘汰的條件，請使用設為現有條件 resource_name 的 remove 建構 CampaignCriterionOperation。
  4. 針對每個新地點或鄰近地區目標，請建立 CampaignCriterionOperation，並在 create 中填入新的 LocationInfo 或 ProximityInfo 條件。
  5. 在單一 MutateCampaignCriteria 呼叫中傳遞 remove 和 create 作業，讓轉場效果以不可分割的方式發生。

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，但排除子區域 (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

如果您使用 LocationGroupInfo，可以啟用廣告活動，指定以地點素材資源定義的地點為中心的多個地理區域，或依地理區域篩選：

  • 地點素材資源組合：設定 enable_customer_level_location_asset_set = true (指定顧客的地點素材資源組合) 或 location_group_asset_sets (指定特定 AssetSet 資源名稱)。這兩個欄位無法同時設定，且都不能與 geo_target_constants 組合。
  • 半徑和單位：LocationGroupInfo 上的半徑會定義每個地點周圍的圓形區域，且需要 radius 和 radius_units (LocationGroupRadiusUnitsEnum)：
    • 使用地點素材資源組合 (enable_customer_level_location_asset_set 或 location_group_asset_sets) 時，支援的 radius_units 值為 MILLI_MILES 和 METERS。
    • 依 geo_target_constants 篩選時 (最多只能有一個條件 ID，且未設定 AssetSet 欄位)，支援的 radius_units 值為 MILES 和 METERS。

GeoTargetTypeSetting 的進階地區選項

除了指定或排除地區，您也可以使用進階地區選項，進一步調整 Google Ads 將使用者與這些地區比對的方式。這些設定是透過 Campaign.GeoTargetTypeSetting 管理。

這項設定包含兩個欄位：

  • positive_geo_target_type：決定系統如何比對使用者與您指定的位置。
  • negative_geo_target_type：決定如何為您排除的地點比對使用者。

明確指定目標設定 (positive_geo_target_type)

您可以從下列選項中選擇正向地區指定目標，並使用 PositiveGeoTargetTypeEnum 中的值：

  • PRESENCE_OR_INTEREST (建議預設值)：

    • 觸及可能位於或經常身在目標地區，以及對目標地區感興趣的使用者。
    • 使用者是否對某地感興趣，可從他們使用的搜尋字詞、過去是否去過該地，以及是否曾瀏覽與該地相關的內容得知。
    • 這個選項的觸及範圍最廣。

  • PRESENCE：

    • 只觸及可能實際位於或經常身在指定地區的使用者。
    • 如果服務或產品僅限於特定地區的消費者，這個選項會更加嚴格，也更實用。

排除指定目標設定 (negative_geo_target_type)

如要排除特定地區，請使用 NegativeGeoTargetTypeEnum：

  • PRESENCE (建議的預設值)：
    • 排除可能實際位於排除地區的使用者。
    • 即使對排除區域感興趣，只要符合您指定的目標對象，排除區域以外的使用者仍可能會看到廣告。

管理進階地區選項

您可以更新 Campaign.geo_target_type_setting 物件來控管這些設定。以下範例顯示 CampaignOperation 更新的結構，該更新會將 positive_geo_target_type 設為 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"
  }
}

如要擷取目前的設定，請在 GoogleAdsService 搜尋查詢中加入 campaign.geo_target_type_setting.positive_geo_target_type 和 campaign.geo_target_type_setting.negative_geo_target_type。

設定這些選項後，您就能根據使用者與指定地理位置的關係，更精細地控管廣告顯示對象，進一步達成業務目標。

最佳做法

  • 如果產品或服務僅限於特定地點的消費者使用，請選擇 PRESENCE。舉例來說，假設你要求使用者必須到店取貨或要求本地配送。
  • 如果產品或服務也能吸引對某個地點感興趣的使用者，即使他們不在該地點，請選擇 PRESENCE_OR_INTEREST。舉例來說，使用者規劃假期時，可能會對目的地城市的飯店感興趣。
  • 使用排除地區指定目標來縮小觸及範圍。如果您以 PRESENCE_OR_INTEREST 指定美國，但無法運送至特定州別，可以在 LocationInfo 條件中使用 negative=true 排除該州別。如果將 negative_geo_target_type 設為 PRESENCE，即可避免向該州的使用者顯示廣告，同時觸及該州以外、可能對美國境內地點感興趣的使用者。
