Google Ads Remarketing Lists Destination

Overview

The Google Ads Remarketing Lists destination is one of Segment’s most popular Engage List destinations. It has a variety of use cases related to exclusion, acquisition (using Similar Audience), remarketing, and more.

This destination can send audiences created in Engage to Google Ads as a Customer List. Once you set this destination up, Segment sends an initial user list of users to the Google Ads API. As users move in and out of the audience, Segment automatically updates the list in Google. This allows you to run advertising campaigns without having to manually update the list of users to target in your Google Ads campaigns.

You can send either an email address or mobile device ID (IDFA) from Engage to Google as custom matchers. You can set an email address on the user profile by including email as a trait on an Identify calls, as a property on a Track calls, or as an external id for the user. If you use Segment’s mobile SDKs to collect events from a mobile app, the user’s IDFA is automatically captured. If you don’t use Segment’s mobile SDKs, you can set the user’s IDFA by setting it within context.device.advertisingId. You must also collect context.device.type and context.device.adTrackingEnabled on the event payload. Additionally, ensure android.idfa and ios.idfa are enabled as identifiers in your Identity Resolution settings in Engage.

When you send an audience to Google Ads Remarketing Lists, you can choose which custom matcher (email or mobile device ID/IDFA) to match with. If a user has multiple emails or IDFAs on their account as external_ids, Engage sends the ID that was most recently added to the user profile to Google Ads.

You can use these audience lists to serve content on Google Search, YouTube, and Gmail. You can only target users with email addresses associated with a Google account, and you can target users in Gmail only if they have an @gmail.com address.

Use cases: known users

Google Ads Remarketing Lists allows you to efficiently run several marketing and advertising operations. The list below contains the most popular use cases when you know personally identifiable information (PII) about your users, such as email addresses or mobile device IDs (IDFA). When you send an Engage audience to Google Ads Remarketing Lists with email addresses or mobile device IDs (IDFA), Segment hashes the PII values before sending them to Google. Google then uses these identifiers to match with users on their ad network to allow the following use cases.

Exclusion audiences (suppression audiences)

Create an audience of users that signed up, purchased a product, or otherwise performed some conversion event. You can then send those users to Google in a timely manner to prevent advertising to users that already converted. You can do this by creating an audience in Engage, syncing it to the Google Ads Remarketing Lists, and setting it as an Exclusion List in your Google Ads campaign.

Similar audience

You can use Engage to create a detailed profile of your most loyal customers (sometimes called a “seed audience”) and then send this list of customers to Google. In Google, you can then use Google’s Similar Audience features to find similar users to target. For example, you might want to create a group of high-value users who have spent a certain amount of money on your product, and then use Similar Audiences to find users who might also spend that much.

Remarketing audiences

You can use Engage to target users who completed some initial action, but didn’t follow through on a purchase or other conversion event. You can create audiences to re-target these individuals and remind them to complete the purchase or other process. For example, you might send an email to someone who didn’t complete a signup form or who didn’t complete a shopping cart checkout.

How it works

When you create an audience in Engage and connect it to Google Ads Remarketing Lists, Segment performs the following actions:

1. Creates a Google Ads User List (Customer List) with the name you entered in Engage.
2. Adds any users that fit the audience definition based on email or mobile ID (IDFA). Google uses these identifiers to match users in your list to users in the Google system who can be served ads.
3. Either adds or removes users from this audience based on the same identifiers.

Setup

Before you start, make sure you have administrative access to the Google Ads account so you can set up and link this destination.

1. Navigate to the Destinations tab in the Engage Settings, and click Add Destination.

2. Search for “Google Ads Remarketing Lists” and click Configure.

3. Click Connect to Google Ads Remarketing Lists and sign in to your Google Ads account. Make sure you sign in to the account that has administrator access.

4. When prompted, click Allow. Segment needs this to update your Google Ads Remarketing Lists.

Consent mode

Consent mode is a feature provided by Google in the context of its products, particularly the Gtag library and Google Analytics. As of March 6, 2024, Google announced that consent mode must function for European Economic Area (EEA) users, otherwise data from EEA users won’t process.

Consent mode in the Gtag library and Google Analytics is designed to help website owners comply with privacy regulations, such as the General Data Protection Regulation (GDPR) in the European Union. It allows website owners to adjust how these tools use and collect data based on user consent.

With consent mode, you can configure your website to dynamically adjust the tracking behavior of the Gtag library and Google Analytics based on the user’s consent status. If a user provides consent to data processing, both the Gtag library and Google Analytics can collect and use that data for analysis. If a user doesn’t provide consent, both tools limit data collection to essential functions, helping businesses respect user privacy preferences.

Consent mode may involve updates to your sources outside of Segment, such as incorporating a consent management system for consent functionality.

Set up consent mode

To enable consent mode for Google Adwords Remarketing Lists destination:

1. Navigate to Connections > Destinations and select your Google Ads Remarketing Lists destination.
2. Go to the Settings tab of the destination.
3. Under the Connection Settings section, select Ad Personalization.
4. Select GRANTED in the dropdown and click Save.
5. Under the Connection Settings section, select Ad User Data.
6. Select GRANTED in the dropdown and click Save.

The consent fields apply universally to all audiences linked to the instance. The consent fields are intended for application across all audiences. If it’s not intended for all audiences, you should create a new instance of the destination and associated non-consent audiences with the new instance. For more information, see FAQ about the EU user consent policy for Customer Match upload partners.

If you have any questions setting up consent mode, reach out to friends@segment.com.

Troubleshooting

Not seeing an audience in Google Ads Audience manager

• Make sure you authorized Google Ads and selected the correct account.
• Make sure you have administrator access for your Google Ads account. You can check that your credentials are correct by navigating to the Google Ads Remarketing Lists destination in Engage Settings > Destinations, and viewing the settings.

Audience size smaller than expected

Engage matches users in your audience using email and mobile device ID (IDFA) values. Make sure you are tracking these with Segment to have as high a match rate as possible.

You can set an email address on the user profile by including email as a trait on an Identify call, as a property on a Track call, or as an external id for the user. If you use Segment’s mobile SDKs to collect events from a mobile app, the user’s IDFA is automatically captured. If you don’t use Segment’s mobile SDKs, you can set the user’s IDFA by setting it within context.device.advertisingId.

If a user has more than one email address or IDFA on their account as external_ids, Engage sends the most recent id on the user profile to Adwords for matching. The match rate will be low if Google can’t identify users based on the data that you provide.

Invalid Settings error in Event Delivery

Make sure that this destination was created in Engage, as it requires additional event data not available in standard destinations.

Invalid user list ID error in Event Delivery

When you first connect a destination to an audience, Segment triggers a call to the destination to create the audience downstream. Once Segment creates the audience, the destination API returns an audience ID. For subsequent updates to the audience in the destination (adding or removing users), Segment uses this ID to send requests to the destination. The invalid user list ID error usually means that the audience ID no longer exists in the destination. To resolve this, you’ll need to either recreate the audience or create a new instance of the destination and link it to the audience. Removing and re-adding the same instance of the destination won’t work.

How do I enter multiple Mobile App IDs when exporting mobile IDs to Google Ads?

If you have more than one App ID (such as a separate App ID for Android and iOS apps), add a separate Google Ads Remarketing Lists destination for each App ID, and make sure the settings for these destinations include the correct App IDs.

When you create Engage audiences, add conditions to specify which App ID to send the audience to. For example, you might add a property condition of “where device.type contains iOS” to send only your iOS users to a specific destination.

Why is there a schemaType validation error when I test an event?

Typically, this is a validation error and the permissions need to be reauthorized. Ensure the user who is authorizing has administration permissions.
