手动设置出价

您可以在广告系列层次结构的不同层级（广告系列、广告组或广告组条件）设置出价。在较低级别设置的出价会覆盖在较高级别设置的出价。例如，在广告系列中为单个广告组设置的出价会覆盖广告系列级出价策略的出价。

更新出价

您可以同时设置多种不同类型的出价；例如，cpc_bid_micros 和 cpm_bid_micros 都可以设置，但系统只会使用与所选出价策略类型相关的出价。

更新出价时，您只需添加要更新的出价即可。然后，Google Ads 会更新这些出价，但不会更改、添加或移除其他出价。

以下代码示例会更新现有广告组的每次点击费用出价。

Java

public static void main(String[] args) {
  UpdateAdGroupParams params = new UpdateAdGroupParams();
  if (!params.parseArguments(args)) {

    // Either pass the required parameters for this example on the command line, or insert them
    // into the code here. See the parameter class definition above for descriptions.
    params.customerId = Long.parseLong("INSERT_CUSTOMER_ID_HERE");
    params.adGroupId = Long.parseLong("INSERT_AD_GROUP_ID_HERE");
    params.cpcBidMicroAmount = Long.parseLong("INSERT_CPC_BID_MICRO_AMOUNT_HERE");
  }

  GoogleAdsClient googleAdsClient = null;
  try {
    googleAdsClient = GoogleAdsClient.newBuilder().fromPropertiesFile().build();
  } catch (FileNotFoundException fnfe) {
    System.err.printf(
        "Failed to load GoogleAdsClient configuration from file. Exception: %s%n", fnfe);
    System.exit(1);
  } catch (IOException ioe) {
    System.err.printf("Failed to create GoogleAdsClient. Exception: %s%n", ioe);
    System.exit(1);
  }

  try {
    new UpdateAdGroup()
        .runExample(
            googleAdsClient, params.customerId, params.adGroupId, params.cpcBidMicroAmount);
  } catch (GoogleAdsException gae) {
    // GoogleAdsException is the base class for most exceptions thrown by an API request.
    // Instances of this exception have a message and a GoogleAdsFailure that contains a
    // collection of GoogleAdsErrors that indicate the underlying causes of the
    // GoogleAdsException.
    System.err.printf(
        "Request ID %s failed due to GoogleAdsException. Underlying errors:%n",
        gae.getRequestId());
    int i = 0;
    for (GoogleAdsError googleAdsError : gae.getGoogleAdsFailure().getErrorsList()) {
      System.err.printf("  Error %d: %s%n", i++, googleAdsError);
    }
    System.exit(1);
  }
}
