您网站的访问者

最简单的细分受众群类型就是您网站的访问者。

前提条件

如需创建和定位目标受众群体细分，您首先需要：

查看针对用户兴趣和地理位置投放广告的政策。有关用户的敏感信息不能用于创建受众群体。
设置 Google 代码。

如果广告客户希望根据移动应用行为创建用户名单，则应实现 Firebase SDK 或使用第三方 SDK 来跟踪应用内行为。

检索 Google 代码

所有 Google Ads 账号都只有一个账号级 Google 代码，该代码会在账号开通时自动创建。

您可以在 Google Ads 界面中按照帮助中心说明检索 Google 代码，也可以在 Google Ads API 中通过创建 RemarketingAction 来检索 Google 代码，然后使用 remarketing_action 资源发出 GoogleAdsService.searchStream 请求：

SELECT
  remarketing_action.id,
  remarketing_action.name,
  remarketing_action.tag_snippets
FROM remarketing_action
WHERE remarketing_action.resource_name = 'REMARKETING_ACTION_RESOURCE_NAME'

在网站或应用中添加 Google 代码

接下来，您需要在网站的所有网页上添加 Google 代码。详细了解如何向网站或移动应用添加 Google 代码。

如果您计划仅根据访问过的网页网址来构建细分受众群，则无需对 Google 代码进行任何修改。如果您使用自定义参数，则需要修改代码以加入这些参数，如编写代码和创建再营销名单的高级策略中所述。

您可以使用 Google Tag Assistant 验证代码植入情况。

内置 Google 代码参数

您可以使用内置的再营销参数 url__，根据用户在您网站上访问过的网址来定位用户名单，如网站访问者示例中所示。

自定义 Google 代码参数

您可以向 Google 代码添加自定义 Google 代码参数，以创建更精细的用户名单。

在创建自己的自定义参数之前，请查看预定义参数列表，看看是否已有适合您用例的参数。使用预定义的参数可以更轻松地与其他 Google Ads 再营销功能集成。

创建用户列表

您需要创建一个用户列表，其中包含触发了您网站上配置的再营销代码的用户。使用 UserListService 创建和管理用户列表。

如需创建包含访问过您网站上任意网页的所有用户的名单，请使用 RuleBasedUserListInfo 对象设置 UserList 的 rule_based_user_list 字段。

接下来，在 RuleBasedUserListInfo 对象中指定 FlexibleRuleUserListInfo 字段，该字段包含定位到访问过您网站的用户的规则。

创建基于规则的用户名单的代码示例

Java

private String createUserList(GoogleAdsClient googleAdsClient, long customerId) {
  // Creates a rule targeting any user that visited a url containing 'example.com'.
  UserListRuleItemInfo rule =
      UserListRuleItemInfo.newBuilder()
          // Uses a built-in parameter to create a domain URL rule.
          .setName("url__")
          .setStringRuleItem(
              UserListStringRuleItemInfo.newBuilder()
                  .setOperator(UserListStringRuleItemOperator.CONTAINS)
                  .setValue("example.com")
                  .build())
          .build();

  // Specifies that the user list targets visitors of a page based on the provided rule.
  FlexibleRuleUserListInfo flexibleRuleUserListInfo =
      FlexibleRuleUserListInfo.newBuilder()
          .setInclusiveRuleOperator(UserListFlexibleRuleOperator.AND)
          // Inclusive operands are joined together with the specified inclusiveRuleOperator.
          .addInclusiveOperands(
              FlexibleRuleOperandInfo.newBuilder()
                  .setRule(
                      UserListRuleInfo.newBuilder()
                          .addRuleItemGroups(
                              UserListRuleItemGroupInfo.newBuilder().addRuleItems(rule)))
                  // Optional: adds a lookback window for this rule, in days.
                  .setLookbackWindowDays(7L))
          .build();

  // Defines a representation of a user list that is generated by a rule.
  RuleBasedUserListInfo ruleBasedUserListInfo =
      RuleBasedUserListInfo.newBuilder()
          // Optional: To include past users in the user list, set the prepopulation_status to
          // REQUESTED.
          .setPrepopulationStatus(UserListPrepopulationStatus.REQUESTED)
          .setFlexibleRuleUserList(flexibleRuleUserListInfo)
          .build();

  // Creates the user list.
  UserList userList =
      UserList.newBuilder()
          .setName("All visitors to example.com" + getPrintableDateTime())
          .setDescription("Any visitor to any page of example.com")
          .setMembershipStatus(UserListMembershipStatus.OPEN)
          .setMembershipLifeSpan(365)
          .setRuleBasedUserList(ruleBasedUserListInfo)
          .build();

  // Creates the operation.
  UserListOperation operation = UserListOperation.newBuilder().setCreate(userList).build();

  // Creates the user list service client.
  try (UserListServiceClient userListServiceClient =
      googleAdsClient.getLatestVersion().createUserListServiceClient()) {
    // Adds the user list.
    MutateUserListsResponse response =
        userListServiceClient.mutateUserLists(
            Long.toString(customerId), ImmutableList.of(operation));
    String userListResourceName = response.getResults(0).getResourceName();
    // Prints the result.
    System.out.printf("Created user list with resource name '%s'.%n", userListResourceName);
    return userListResourceName;
  }
