效果最大化广告系列素材资源组

效果最大化广告系列的素材资源组由您在制作效果最大化广告系列时添加的图片、标题、广告内容描述和视频构成。为了优化广告效果，系统会智能地选择并组合您的素材资源，以最适合展示广告的特定 Google Ads 渠道（例如 YouTube、Gmail 或 Google 搜索）。

素材资源组无法在广告系列之间共享。每个广告系列都需要至少一个素材资源组。每个广告系列最多只能包含 100 个素材资源组。

素材资源组

素材资源组是以一个主题为中心或与一个目标受众群体相关的素材资源集合。素材资源组用于组合生成您的所有广告，以便采用所有适用的广告格式加以投放，从而达成您的广告目标。详细了解素材资源组。

素材资源组包含一个或多个最终到达网址。至少需要一个最终到达网址。使用与指定素材资源组和广告系列目标的转化路径最相关的网址。素材资源组的最终到达网址无法从WEBPAGE 广告系列条件中排除。

将素材资源组与素材资源相关联

通过创建新的 AssetGroupAsset 并提供以下内容，将 AssetGroup 关联到 Asset：

AssetGroup 的资源名称
Asset 的资源名称
AssetGroup中Asset的AssetFieldType

一个 AssetGroup 可以关联到多个 Asset 对象。Asset 可以关联到多个素材资源组。一个 Asset 在不同的 AssetGroup 对象中可以具有不同的字段类型。

限制条件：

AssetGroupOperation 请求必须是原子化请求。不支持部分失败。
无法使用 AssetGroupOperation 在批量处理中修改素材资源组资源。请改用标准 GoogleAdsService.Mutate 和 AssetGroupService，以在批量处理过程中修改素材资源组资源。
AssetGroupAssetOperation 可在 BatchJobService 中用于将素材资源与素材资源组相关联或取消关联。

将素材资源组与效果最大化零售广告系列中的素材资源相关联

您可以在效果最大化零售广告系列中制作 AssetGroup 对象，而无需满足最低素材资源要求。不过，如果尝试在任何效果最大化广告系列中使用 AssetGroupAsset 将 Asset 链接到 AssetGroup，则会触发所有素材资源要求生效。换句话说，效果最大化零售广告系列中的 AssetGroup 对象只能处于以下两种状态：

没有任何关联的 Asset 对象
满足所有 Asset 要求

根据最佳实践，我们建议您上传素材资源，以便在所有广告资源中最大限度地扩大覆盖面。不过，您必须在单个请求中关联所有必需的素材资源，而不得使用部分失败，并且不能通过单独的请求一次性向素材资源组添加一个素材资源。
