Enhanced conversions for web is a feature that can improve the accuracy of your conversion measurement. It supplements your existing conversion data by sending hashed first-party customer data in a privacy-safe way. The hashed customer data is compared to hashed customer data of signed-in Google accounts and attributed to ad events such as clicks and video views to help measure your campaign conversions.
This article will explain how to set up enhanced conversions using the Google Ads API.
Benefits
- First-party data can be provided after the conversion event: Unlike other enhanced conversions options like tagging that require you to send first-party data at the time of the conversion, you can use the API to send hashed first-party data up to 24 hours after the conversion event. This also enables you to locate first-party data from other sources, such a customer database or CRM system.
- More choices for your data source: Using the API enables you to locate first-party data from a variety of sources, such as a customer database or CRM system.
Note: App incrementality studies currently require a different API implementation than what’s described in this article. Reach out to your sales representative if you're interested in this type of experiment.
How it works
Using the Google Ads API, you can leverage enhanced conversions by sending first-party customer data in the form of conversion adjustments. The process for sending enhanced conversion data is similar to other conversion adjustments with some key differences. Learn how to implement enhanced conversions for web using Google Ads API conversion adjustments.
In order to implement enhanced conversions using the Google Ads API, you must record conversions using a regular conversion tracking tag on your website. After a conversion is recorded, you can then send hashed first-party data (such as email address, phone number, name, and/or home address) via an API connection up until 24 hours after the conversion.
The hashed data you send us is matched against Google logged-in user data and a conversion is reported in your account.
Before you begin
- Make sure you've Set up conversion tracking for your website.
Note: Conversions measured by importing Google Analytics goals aren't supported for enhanced conversions. If you'd like to use enhanced conversions, consider setting up a new Google Ads conversion action with a Google tag or Google Tag Manager.
- Know the conversion page URL where the conversion tag fires (such as the confirmation page URL) and the conversion event trigger (for example, a button click or a page view).
- Make sure that there is first-party customer data available (email, full name and home address and/or phone number).
- Make sure that you’ve reviewed the Customer data policies and agreed to the terms of service and policies in Google Ads (refer to steps on this below, under Instructions).
