Enhanced conversions is a feature that can improve the accuracy of your conversion measurement. It supplements your existing Floodlight conversion tags by sending hashed first-party conversion data from your website to Google in a way that is consistent with our applicable privacy policies.
The feature uses a secure, one-way hashing algorithm called SHA256 on your first-party customer data, such as email addresses, before sending it to Google. The hashed data is then matched with signed-in Google accounts to attribute your campaign conversions to ad events, such as clicks or views.
To get started, follow these instructions:
- If you use Google Tag Manager, learn how to set up enhanced conversions with Google Tag Manager.
- If you use the Google tag, learn how to set up enhanced conversions with Google tag.
Google is committed to protecting the confidentiality and security of your data. Your data will be kept confidential and secure using the same industry-leading standards Google uses to protect its own users’ data. Google only reports aggregated and anonymised conversions.

When a customer completes a conversion on your website, you may receive first-party customer data, including an email address, a name, a home address and/or a phone number. This data is captured in your Floodlight tags, hashed and sent to Google in its hashed form. It’s then used to match your customers to the Google accounts they were signed into when they engaged with your ad.
Google uses the SHA256 algorithm for hashing your customer data, which is the industry standard for one-way data hashing.
