Similar Audiences

One way of reaching new audiences is using a similar_user_list. With this user list, you can reach people who share characteristics with those in your other user lists.

A similar_user_list is automatically generated by Google for each UserList, based on a variety of factors; for example, the number of people on the original list, how recently they joined the list, the types of sites they browsed, and whether the list is yours. This process may take up to four days starting from when the source list was created.

The Google Ads Query Language query demonstrates how to find all available similar_user_list objects given a seed user list.

SELECT
  user_list.id,
  user_list.name
FROM user_list
WHERE user_list.similar_user_list.seed_user_list = SEED_LIST_RESOURCE_NAME;

Target the list

With your similar user lists identified, the next step is to target them.

Audience segment targeting rules

  1. Positive (biddable) user lists cannot be set at the campaign level and the ad group level at the same time. Positive user list criteria must be removed from all ad groups within a campaign before one can be set for the campaign.

  2. Positive targeting by user list is only supported for Search campaigns. For Display campaigns, CampaignCriterion that sets user_list must be excluded.

  3. In Search and Shopping campaigns, user list targets don't support setting the following fields:

Target ads to your user list

The process is similar to other types of targeting criteria in the API. The following code demonstrates how you can use an AdGroupCriterion to target ads in an ad group to a user list:

Java

private String targetAdsInAdGroupToUserList(
    GoogleAdsClient googleAdsClient, long customerId, long adGroupId, String userList) {
  // Creates the ad group criterion targeting members of the user list.
  AdGroupCriterion adGroupCriterion =
      AdGroupCriterion.newBuilder()
          .setAdGroup(ResourceNames.adGroup(customerId, adGroupId))
          .setUserList(UserListInfo.newBuilder().setUserList(userList).build())
          .build();

  // Creates the operation.
  AdGroupCriterionOperation operation =
      AdGroupCriterionOperation.newBuilder().setCreate(adGroupCriterion).build();

  // Creates the ad group criterion service.
  try (AdGroupCriterionServiceClient adGroupCriterionServiceClient =
      googleAdsClient.getLatestVersion().createAdGroupCriterionServiceClient()) {
    // Adds the ad group criterion.
    MutateAdGroupCriteriaResponse response =
        adGroupCriterionServiceClient.mutateAdGroupCriteria(
            Long.toString(customerId), ImmutableList.of(operation));
    // Gets and prints the results.
    String adGroupCriterionResourceName = response.getResults(0).getResourceName();
    System.out.printf(
        "Successfully created ad group criterion with resource name '%s' "
            + "targeting user list with resource name '%s' with ad group with ID %d.%n",
        adGroupCriterionResourceName, userList, adGroupId);
    return adGroupCriterionResourceName;
  }
}

Switch targeting levels

If you are switching from ad group level user list criteria to campaign level, you must first remove the existing user list criteria from each enabled or paused ad group under that campaign. Click the expandable elements to view example code for each step.

First, retrieve all of the AdGroupCriteria under a given campaign.

Target ads in a campaign to a user list, using a CampaignCriterion.

Review list performance

In order to collect performance data for your audience segments, issue a search request against the ad_group_audience_view or the campaign_audience_view resource. For example, you might look at the conversions or cost_per_conversion to determine if targeting the audience segment is actually leading to more conversions, then adjust your bid modifiers accordingly.

SELECT
  ad_group_criterion.criterion_id,
  metrics.conversions,
  metrics.cost_per_conversion
