建立需求開發委刊項

需求開發委刊項會在 Google 最具影響力的平台上 (包括 YouTube、探索、Gmail 和 Google 多媒體廣告聯播網)，放送多種格式的廣告群組和廣告。與其他類型的委刊項一樣，需求開發委刊項也是使用 LineItem 資源進行管理，並根據設定的預算、出價策略和指定目標運作。demandGenSettings 欄位也提供需求開發委刊項專屬設定。

需求開發委刊項有稱為廣告群組的子資源。廣告群組可提供個別委刊項的另一層級控制項。

選擇設定

建立需求開發委刊項前，請先查看並決定相關設定。

需求開發委刊項：

lineItemType 必須設為 LINE_ITEM_TYPE_DEMAND_GEN。
必須使用 BiddingStrategy 物件的 demandGenBid 欄位設定 bidStrategy。
budget 必須在委刊項層級設為固定金額，且無法從父項廣告訂單沿用。
demandGenSettings 用於設定需求開發委刊項專屬的設定。DemandGenSettings 物件的 geoLanguageTargetingEnabled 欄位會控管是在委刊項層級還是個別廣告群組中，設定地區和語言指定目標。委刊項建立後，這個欄位就無法更新。如要在委刊項層級設定這項指定目標，請將該欄位設為 true。
不應設定「creativeIds」。素材資源會直接在 AdGroupAd 資源中指派及設定。

需求開發委刊項必須填寫下列欄位，運作方式與其他類型的委刊項相同：

LineItem 資源也有許多可設定的選用欄位。詳情請參閱參考文件。

建立委刊項

如要使用下列設定建立需求開發委刊項，請按照下列步驟操作：

沿用航班和 $100 美元的預算。
夥伴收益模式為媒體費用總額的 0.1%。
這項出價策略會盡可能爭取轉換，同時將平均單次轉換出價維持在 $10 美元。
偏好直接將指定地區和語言指派給委刊項下的廣告群組。
