效果最大化广告系列中的素材资源

效果最大化广告系列在素材资源方面有一些独特的特征。

需要有不同类型的素材资源，且数量不得少于最低要求。
素材资源会分组到名为 AssetGroup的集合中，这是效果最大化广告系列独有的。
有些素材资源可以通过机器学习自动生成。

品牌规范：商家名称和徽标关联

虽然效果最大化广告系列中的大多数素材资源都归属于素材资源组，但代表品牌身份的关键素材资源（具体而言，即 商家名称 和 商家徽标）的处理方式有所不同，前提是您的广告系列已启用品牌规范。

这些品牌规范素材资源直接在广告系列一级关联，而不是在素材资源组一级关联。这是通过 CampaignAsset 资源完成的。您将素材资源与广告系列相关联，并指定相应的 AssetFieldType：

BUSINESS_NAME，用于商家名称素材资源（属于文字素材资源）。
LOGO，用于商家徽标素材资源（属于图片素材资源）。

这种广告系列级关联可确保效果最大化广告系列中的所有素材资源组都以一致的方式呈现品牌。

代码示例

以下代码段演示了如何在新的请求中创建必要的重复素材资源：

Java

/** Creates multiple text assets and returns the list of resource names. */
private List<String> createMultipleTextAssets(
    GoogleAdsClient googleAdsClient, long customerId, List<String> texts) {
  List<MutateOperation> mutateOperations = new ArrayList<>();
  for (String text : texts) {
    Asset asset = Asset.newBuilder().setTextAsset(TextAsset.newBuilder().setText(text)).build();
    AssetOperation assetOperation = AssetOperation.newBuilder().setCreate(asset).build();
    mutateOperations.add(MutateOperation.newBuilder().setAssetOperation(assetOperation).build());
  }

  List<String> assetResourceNames = new ArrayList<>();
  // Creates the service client.
  try (GoogleAdsServiceClient googleAdsServiceClient =
      googleAdsClient.getLatestVersion().createGoogleAdsServiceClient()) {
    // Sends the operations in a single Mutate request.
    MutateGoogleAdsResponse response =
        googleAdsServiceClient.mutate(Long.toString(customerId), mutateOperations);
    for (MutateOperationResponse result : response.getMutateOperationResponsesList()) {
      if (result.hasAssetResult()) {
        assetResourceNames.add(result.getAssetResult().getResourceName());
      }
    }
    printResponseDetails(response);
  }
  return assetResourceNames;
}
