Visitors who Took Specific Actions

You can populate your audience list with people who have taken specific actions on your website. If you're using conversion tracking, you can target ads to people who previously triggered a conversion (such as a purchase) on your website.

You can also target ads to people who have taken a particular action on your website that you do not consider a conversion, such as when a person adds but then deletes an item from their shopping cart without making a purchase.

Prerequisites

In order to create and target audience segments, you first need to:

  1. Review the policy for advertising based on interests and location. Sensitive information about users can't be used to build audiences.

  2. Set up your Google tag.

    Advertisers seeking to create user lists based on mobile app behavior should implement the Firebase SDK or work with third-party SDKs in order to track in-app behavior.

1. Set up conversion tracking. Follow the instructions in the conversion management overview. Then install the Google tag on your website.

Retrieve the Google tag

All Google Ads accounts have exactly one account-level Google tag, created automatically when the account is opened.

You can retrieve the Google tag in the Google Ads UI by following the Help Center instructions or in the Google Ads API by creating a RemarketingAction and then retrieving the Google tag by issuing a GoogleAdsService.searchStream request using the remarketing_action resource:

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

Install the Google tag on your website or app

The next step is to install your Google tag on all of your site's pages. Learn more about adding the Google tag to your site or mobile app.

If you're planning to build audience segments based only on visited page URLs, you don't need to make any edits to your Google tag. If you're using custom parameters, you need to edit your tag to include them, as detailed in Advanced strategies for tagging and creating remarketing lists.

You can use Google Tag Assistant to validate your tag installation.

Built-in Google tag parameters

You can use the built-in remarketing parameter url__ to target a user list based on the URLs that people have visited on your website, as demonstrated in the Visitors to your website example.

Custom Google tag parameters

You can add custom Google tag parameters to your Google tag to create more tailored user lists.

Before creating your own custom parameters, check out the list of predefined parameters to see if there's already a good fit for your use case. Using predefined parameters makes it easier to integrate with other Google Ads remarketing features.

Create the user list

Targeting visitors who took specific actions requires setting the basic_user_list field of a UserList with a BasicUserListInfo object containing references to the actions—whether conversions or non-conversion actions— you are targeting.

For a complete walkthrough of an example scenario in which you target users based on a combination of conversion and non-conversion actions, check out the Sample scenario.

Visitors who triggered a conversion

A basic user list defines its membership as people who had triggered one or more conversion actions on your website. When you create a basic user list, you provide the resource name of the ConversionAction to a UserListActionInfo object, which is ultimately passed to the UserList.

The following example creates a basic user list associated with two existing conversion actions:

Java

private void runExample(
    GoogleAdsClient googleAdsClient, long customerId, List<Long> conversionActionIds) {
  List<UserListActionInfo> userListActionInfoList = new ArrayList<>();
  for (long conversionActionId : conversionActionIds) {
    // Creates the UserListActionInfo object for a given conversion action. This specifies the
    // conversion action that, when triggered, will cause a user to be added to a UserList.
    UserListActionInfo userListActionInfo =
        UserListActionInfo.newBuilder()
            .setConversionAction(ResourceNames.conversionAction(customerId, conversionActionId))
            .build();
    userListActionInfoList.add(userListActionInfo);
  }

  // Creates a basic user list info object with all of the conversion actions.
  BasicUserListInfo basicUserListInfo =
      BasicUserListInfo.newBuilder().addAllActions(userListActionInfoList).build();

  // Creates the basic user list.
  UserList basicUserList =
      UserList.newBuilder()
          .setName("Example BasicUserList #" + getPrintableDateTime())
          .setDescription("A list of people who have triggered one or more conversion actions")
          .setMembershipLifeSpan(365)
          .setBasicUserList(basicUserListInfo)
          .setMembershipStatus(UserListMembershipStatus.OPEN)
          .build();

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

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

C#

public void Run(GoogleAdsClient client, long customerId, long[] conversionActionIds)
{
    // Creates the service client.
    UserListServiceClient userListServiceClient =
        client.GetService(Services.V17.UserListService);

    List<UserListActionInfo> userListActionInfoList = new List<UserListActionInfo>();
    foreach (long conversionActionId in conversionActionIds)
    {
        // Creates the UserListActionInfo object for a given conversion action. This
        // specifies the conversion action that, when triggered, will cause a user to be
        // added to a UserList.
        userListActionInfoList.Add(new UserListActionInfo
        {
            ConversionAction =
                ResourceNames.ConversionAction(customerId, conversionActionId)
        });
    }

    // Creates a basic user list info object with all of the conversion actions.
    BasicUserListInfo basicUserListInfo = new BasicUserListInfo();
    basicUserListInfo.Actions.Add(userListActionInfoList);

Visitors who took non-conversion actions

You can create a basic user list for people who took actions on your website that you don't consider conversions by associating it with a RemarketingAction instead of a ConversionAction.

Retrieve the list

To retrieve your user list, you can issue the following Google Ads Query Language query to the user_list resource.

SELECT
  user_list.name,
  user_list.membership_status,
  user_list.membership_life_span
FROM user_list
WHERE
  user_list.resource_name = 'USER_LIST_RESOURCE_NAME'

Target the list

With your audience segment created, the next step is to target it.

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;
  }

As with other types of criteria, you can assign other properties to the AdGroupCriterion object, such as bid overrides.

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.

Java

    GoogleAdsClient googleAdsClient, long customerId, long campaignId) {
  List<String> userListCriteria = new ArrayList<>();

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
FROM ad_group_audience_view
