示例：使用 Google Merchant Center 制作动态再营销广告系列

在此示例中，您有一个零售网站，该网站会将商品详情上传到 Google Merchant Center，并且您希望向访问过该零售网站的用户再营销一组商品。这些用户可能访问过产品页面，或将商品放入购物车或结账，而这些行为会触发再营销标记。然后，您可以制作一个广告系列，仅定位此群组，也可以定位类似受众群体，以扩大覆盖面。

详细了解受众群体名单生成最佳实践。

您需要具备以下条件才能设置此类广告系列：

再营销名单。
Merchant Center 账号。
来自 Merchant Center 的商品 Feed。
自适应展示广告所需的媒体资源。

以下是支持 Merchant Center 商品 Feed 的广告素材列表：

第 1 步 - 制作与 Merchant Center 产品 Feed 相关联的广告系列

如需对零售商品进行再营销，您需要制作以展示广告网络为定位目标的广告系列。这需要满足以下条件：

一个 CampaignBudget，用于指定广告系列能够支出的金额。
一个 UserList，其中包含要通过相应广告系列定位的用户名单。
ShoppingSetting 用于指定商品 Feed 将用于哪个 Merchant Center 账号的广告系列。

配置广告系列的基本步骤如下：

制作新的广告系列，并将 AdvertisingChannelType 设置为 DISPLAY。
为广告系列设置CampaignBudget。可以是新创建的预算，也可以是共享预算。
为广告系列设置 ShoppingSetting。请注意，此处使用的是 CampaignService，而不是 AdGroupService，因为 Feed 必须附加到广告系列一级。
- 首先，将 merchant_id 设置为与 Google Ads 账号关联的 Merchant Center 账号的 merchant_id。此 Merchant Center 账号必须已与 Google Ads 相关联，如这篇文章中所述。
- 然后，按照这篇文章中的说明设置 campaign_priority。
- 将 enable_local 设置为 true 将包含本地商品目录广告。
应用 mutate 操作，将新广告系列添加到账号中。
