動態再行銷廣告是針對每次曝光量身打造的多媒體廣告，會顯示與使用者先前造訪網站相關的內容。
動態再行銷有許多優點，包括：
- 可擴充性：與動態饋給配對後，即可建立配合產品或服務擴充的廣告。
- 簡單卻強大的素材資源：建立動態饋給後，Google Ads 產品推薦引擎會擷取產品和服務，再根據熱門程度和訪客在您網站上的瀏覽記錄，決定各個廣告的最佳產品組合。
- 高成效版面配置：Google Ads 會根據廣告的放送平台、刊登位置和目標對象，預測哪一種動態廣告版面配置能夠獲得最佳成效。
- 即時出價最佳化：Google Ads 會使用轉換最佳化工具，計算出個別曝光的最佳出價。
Google Ads API 支援兩種動態再行銷廣告活動：零售和非零售。零售業專用動態再行銷需要 Merchant Center 提供的動態饋給，而非零售業則可使用Assets維護。
其餘頁面提供各業務類型的動態再行銷廣告更新範例。
