效果最大化广告系列在素材资源方面具有一些独特的特征。
- 不同类型的素材资源达到最低数量要求。
- 素材资源会归到一个称为
AssetGroup的集合中，这是效果最大化广告系列独有的集合。 - 有些素材资源可由机器学习技术自动生成。
代码示例
以下代码段展示了如何在新请求中创建必要的重复资源：
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;
}

自动制作的素材资源
使用机器学习技术的 Google 自动化功能会根据需要生成额外的素材资源，以覆盖所有相关渠道。系统会根据广告投放到的 Google Ads 渠道（例如 YouTube、Gmail 或 Google 搜索），自动组合搭配素材资源。
文字素材资源
您可以将帐号中的页面 Feed 与效果最大化广告系列相关联，以自动生成素材资源。
要将页面 Feed 与广告系列相关联，请按照与动态搜索广告相同的流程操作：
关联页面 Feed 后，请确保将 TEXT_ASSET_AUTOMATION 类型的 AssetAutomationSetting 设置为 OPTED_IN。如果您在创建广告系列时未设置 AssetAutomationSetting，则此为默认设置。
使用此设置后，如果系统预测有助于提升广告效果，您的广告系列就可以使用着陆页、网域和所提供素材资源中的内容来定制广告。我们建议将其保留为 OPTED-IN。
视频素材资源
如果您不向效果最大化广告系列素材资源组中添加视频，系统可能会根据素材资源组中的素材资源生成一个或多个视频素材资源。如果您不想再在效果最大化广告系列中投放自动生成的视频，则可以上传自己的自定义视频，这样自动生成的视频就会停止投放。
