Google Ads Conversions Destination

The Google Ads destination allows users to upload conversions, conversion adjustments, and customer match lists in a privacy-safe manner. Marketers can use this integration to re-engage users across Search, Shopping, Gmail, YouTube, and Display by combining conversion data with customer match lists for more effective targeting.

Data normalization

To improve match rates, Segment built in normalization and hashing for common fields to align with Google’s best practices outlined in Google’s Prepare data for upload and Add customer data documentation.

Normalization

Segment automatically strips whitespace and converts the following fields to lowercase:

• Email
• First name
• Last name

Segment normalizes the Phone field by removing any non-numeric symbols. Segment also converts each phone number to E.164 format before hashing. E.164 format represents a phone number as a number up to fifteen digits in length starting with a + sign.

Hashing

Google requires you to hash all PII before sending it to the Google API.

Segment automatically hashes any of the following fields that are not already hashed at egress:

• Email
• Phone number
• First name
• Last name

Actions v2

Segment’s v2 Actions, Call Conversion v2, Conversion Adjustment v2, and Click Conversion v2, support the following features:

• Sync modes: Control how Segment updates your downstream destination by selecting a sync mode, or a strategy for updating your downstream data.
• Dynamic dropdowns: When creating or updating a mapping in the Segment app, the dropdown auto-populates all of the available properties directly from Google Ads.
• Create and modify data: Use Sync modes to create objects in your downstream destination without having to leave the Segment app.

Sync modes

Sync modes allow users to define how Segment should update the data in your destination.

Sync modes available for v2 Actions include:

• Add: Add records to a list, segment, or journey.

Destination Settings

Required if you are using a mapping that sends data to the legacy Google Enhanced Conversions API (i.e. Upload Enhanced Conversion (Legacy) Action).

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 your Google Ads Conversions destination, you must update the Ad User Data Consent State and Ad Personalization Consent State for all of your Upload Call Conversion and Upload Click Conversion actions. You can do this in 1 of 2 ways:

• Option 1:
  1. Navigate to Connections > Destinations and select your Google Ads Conversion destination.
  2. Go to the Mappings tab of the destination.
  3. Select the mapping you want to edit.
  4. In the Select mappings section, select GRANTED from the dropdown menu for Ad User Data Consent State and Ad Personalization Consent State.
• Option 2:
  1. Navigate to Connections > Destinations and select your Google Ads Conversion destination.
  2. Go to the Mappings tab of the destination.
  3. Select the mapping you want to edit.
  4. In the Select mappings section, for Ad User Data Consent State and Ad Personalization Consent State, select the Event Variables tab and create an event variable to directly grab the value from the payload. Ensure it translates to GRANTED, DENIED, or UNSPECIFIED. You can use an insert or replace function to translate other values to GRANTED, DENIED, or UNSPECIFIED.

If you send DENIED for any of the two consent states, it results in an error and the data won’t send to Google. 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.

FAQ and troubleshooting

Conversion ID, Customer ID, and Conversion Action ID should always be different values

Conversion ID and Customer ID are global settings because it’s an account-level ID that’s the same for all conversion actions in your Google Ads account.

The Conversion Action ID is unique to each conversion action and is configured per mapping. The Conversion Action ID can only be found in the browser URL of your given conversion action under the ctId parameter. For example, if the URL is https://ads.google.com/aw/conversions/detail?ocid=00000000&ctId=576882000, your Conversion Action ID is 576882000.

Enhanced conversions

Enhanced conversions is a feature that can improve the accuracy of your conversion measurement and unlock more powerful bidding. It supplements your existing conversion tags by sending hashed, first-party conversion data from your website to Google in a privacy safe way. You can use the “Upload Conversion Adjustment” action to send enhancements to the Google Ads API. In order to send enhanced conversions, you must record first conversions using the standard Google Ads Conversion tag (Gtag). Segment offers a Google Ads (Gtag) destination so you can use your existing Segment implementation to activate Gtag. Enhancements can be sent to web conversion actions that have Turn on enhanced conversions by API enabled.

Conversions tracked by other means, such as importing goals from Google Analytics, are not eligible for enhancement.

Enhanced conversions for leads

Enhanced conversions for leads allows you to use hashed, first-party user-provided data from your website lead forms for offline lead measurement. When you upload your leads, the provided hashed information is used to attribute back to the Google Ad campaign. In order to send enhanced conversions for leads, you can use the “Upload Click Conversion” action. According to Google, if you do not have GCLID at your source payload, you have to pass user identifiers, at least email or phone number in your mappings, for Google to make the match. A conversion must be addressed to an existing profile. If there’s not a match, Google responds with a failure.

Refreshing access tokens

When you use OAuth to authenticate into the Google Ads Conversions destination, Segment stores an access token and refresh token. Access tokens for Google Ads Conversions expire after one hour. Once expired, Segment receives an error and then uses the refresh token to fetch a new access token. This results in two API requests to Google Ads Conversions, one failure and one success.

Because of the duplicate API requests, you may see a warning in Google for unprocessed conversions due to incorrect or missing OAuth credentials. This warning is expected and does not indicate data loss. Google has confirmed that conversions are being processed, and OAuth retry behavior will not cause any issues for your web conversions. Whenever possible, Segment caches access tokens to reduce the total number of requests made to Google Ads Conversions.

Resolving an invalid_conversion_action_type error

This error indicates that the conversion action specified in the upload request has not been set up for conversion uploads, as outlined in Google’s Ads documentation.

To resolve this, ensure that the ConversionActionType value in Google Ads is correctly configured.

Conversion upload error

You may encounter this error if you use more than one identifier to update a conversion. You must only use one identifier (GCLID, GBRAID, or WBRAID) for each ClickConversion entry.

The required field was not present., at conversions[0].gclid Error

Events going to Google for this integration require a GCLID field, an email, or a phone_number. If one of those identifiers isn’t being sent properly, then you may see the The required field was not present., at conversions[0].gclid error. To fix this, double check that at least one of those fields is being passed to Google on each payload.
