評估電子商務

電子商務可評估使用者在購物過程中與產品的互動情形，包括產品 (商品) 清單瀏覽次數、產品清單點擊次數、查看產品詳細資料、將產品加入購物車、啟動結帳程序、購買和退款等互動。

如要進一步瞭解如何導入電子商務網站應用程式，請參閱「Google Analytics 電子商務」一文。

事前準備

請確認您已設定專案，並能按照「開始使用 Analytics」一文的說明存取 Analytics。電子商務評估功能需要將 Firebase 專案連結至 Analytics 帳戶，且應用程式必須安裝 Android SDK 17.3.0 以上版本或 iOS 6.20.0 以上版本。

實作

以電子商務來說，一般實務上會評估下列動作：

從清單中選取產品
查看產品詳細資料
將產品加入/移出購物車
啟動結帳程序
購買或退款
套用促銷活動

這些動作的核心就是產品。產品可做為一系列項目進行檢測，並新增至規定的電子商務事件。除了規定的參數外，您最多可以在項目陣列中加入 27 個自訂參數。

以下範例說明如何建立在本指南中參照的項目陣列。

啟動結帳程序

如要評估結帳流程中的第一個步驟，請記錄 begin_checkout 事件，其中包含一或多個使用相關欄位定義的 items。在這個階段，您也可以將優待券新增至事件，藉此將優待券新增至整個訂單，或是將優待券新增至 items 陣列中的特定元素，以便套用至特定商品。

套用促銷活動

電子商務功能支援評估內部宣傳活動的曝光次數和點擊次數，例如用於宣傳特價的橫幅廣告。

促銷活動曝光次數通常會以初始畫面瀏覽次數為基準，方法是使用 items 參數記錄 view_promotion 事件，以指定促銷產品。如要指出使用者點選促銷活動，請記錄 select_promotion 事件，並將該產品做為 item 參數。

傳送以商品為範圍的自訂參數

商品範圍自訂參數是指 Google 在電子商務商品的必要或選用參數清單中未列出的參數。您可以使用自訂參數，收集對自家業務有用的商品資訊。

您可以透過應用程式，在商品陣列中傳送最多 27 個以商品為範圍的自訂參數，其中可分別為標準資源和 Analytics 360 資源各設定 10 個及 25 個以商品為範圍的自訂維度。這樣一來，您就能靈活選用更多項參數，而不需要重新標記應用程式。
