您可以設定電子商務事件，收集使用者的購物行為資訊。有了事件，您就能透過量化評估找出暢銷產品，並瞭解宣傳和產品廣告的刊登位置對收益的影響。
本文將說明各個電子商務事件，以及設定事件的時機。如需設定電子商務事件的逐步範例，請參閱「設定購買事件」。
事前準備
請確認您已在網站中加入 Google 代碼，且可以存取 Analytics 和網站原始碼。
建議
- 啟用偵錯模式，即可即時查看事件並排解問題。
- 透過電子商務事件傳送自訂參數時，請先查看自訂維度和指標的限制。
- 傳送
value(收益) 資料時，請設定currency，確保系統正確計算收益指標。 - 設定您有資料的每個電子商務參數，無論參數是否為選用。
- 請使用電子商務範例網站，查看如何為網站加上代碼。
- 為確保報表能正確填入資料，請按照本文件中的格式操作。如需在電子商務陣列以外設定項目陣列，請在傳送
value(收益) 資料時，於事件層級設定currency參數。
導入作業
以電子商務來說，一般實務上會評估下列動作：
這些動作的核心就是你銷售的產品與服務。你可以將代表產品和服務的一系列項目加入電子商務事件。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本指南中參照的 items 集合。items 陣列最多可包含 200 個元素。
