使用廣告群組管理「購物」廣告活動
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
摘要
您可以使用廣告群組，為購物廣告活動設定出價。
廣告群組可讓您使用出價調整幅度和排除關鍵字等功能。
如果同一個廣告活動下有多個廣告群組包含同一項產品，系統會採用最高出價。
你可以使用產品群組，在廣告群組中細分及安排產品。詳情請參閱「建立產品群組」。
在 Google 購物中，出價是針對產品群組，而非關鍵字。如要進一步瞭解出價做法，請參閱「建立及最佳化購物廣告活動」。
手動步驟
以下說明如何使用 Google Ads 使用者介面設定廣告群組。
- 建立新的購物廣告活動。
- 建立新的廣告群組並輸入名稱。
視廣告活動類型而定，您可以依屬性將廣告群組細分為產品群組。例如：
- 品牌
- 項目 ID
- 自訂標籤
- 產品類型
- Google 產品類別
檢查產品群組。如果沒有細分廣告群組，請參閱「使用產品群組管理購物廣告活動」。
暫停或啟用廣告群組。
詳情請參閱「使用廣告群組管理購物廣告活動」。
自動步驟
以下是使用 Google Ads API 建立廣告群組的步驟。
請確認你已將 Merchant Center 連結至 Google Ads，並建立新的廣告活動。
選取 SHOPPING_PRODUCT_ADS 或 SHOPPING_SMART_ADS 做為
AdGroupType。
AdGroupType 設定後即無法變更。
