Enhanced Conversions in Google Ads: How to Set up Tracking

Feeling frustrated by incomplete data and missed opportunities in your Google Ads campaigns? You’re not alone. Traditional conversion tracking often falls short, leaving you with blind spots and limited insights into your audience’s journey. Say hello to Enhanced Conversions! In this blog post, I will explain what Enhanced Conversions in Google Ads are and how to set them up.

What is Enhanced Conversions in Google Ads?

Simply put, Enhanced Conversions is a feature within Google Ads that allows advertisers to supplement their existing conversion data with additional first-party data from their website. This means that if a user completes a conversion on your website and provides some form of identifiable information (such as an email address or phone number), Google Ads can use this information to match the conversion with a specific user.

This is done in a privacy-safe way, with all data being hashed and anonymized before it’s used. The result is a more accurate understanding of how users are interacting with your ads and converting on your website.

For instance, if a user clicks on your ad on one device but completes the conversion on another, traditional conversion tracking might not attribute the conversion to the ad click. However, Enhanced Conversions can use hashed data, such as an email provided by the user during the conversion process on your site, to match the conversion back to the ad click more accurately.

Benefits of Using Enhanced Conversion Tracking in Google Ads

In the world of digital marketing, data is the cornerstone of every successful campaign. The more accurately you can track your conversions, the better you can optimize your campaigns for maximum return on investment. This is where Enhanced Conversion Tracking in Google Ads comes into play. But what exactly are the benefits this feature brings to your campaigns?

Benefits of using enhanced conversion tracking in Google Ads

More accurate conversion data

One of the primary benefits of Enhanced Conversions is the improved accuracy of conversion data. Traditional conversion tracking methods may not always capture the full picture due to factors like users switching between devices.

Enhanced Conversions addresses this issue by using first-party data from your website, such as hashed email addresses or phone numbers. This additional data allows Google Ads to more accurately attribute conversions to specific users and ad interactions, providing a more precise understanding of how users are interacting with your ads and converting on your website.

Improved campaign optimization

More accurate conversion data translates into better campaign optimization. With a clearer picture of which ads are driving conversions, you can make more informed decisions about where to allocate your budget and how to adjust your bidding strategy. This can lead to improved campaign performance, higher return on investment, and more efficient use of your advertising budget.

Better audience targeting

Enhanced Conversions can also lead to better audience targeting. By gaining a deeper understanding of who is converting on your website, you can create more targeted ad campaigns that resonate with your audience. This can lead to higher engagement rates, improved click-through rates, and ultimately, more conversions.

More accurate insight into the customer journey

Enhanced Conversions provide a deeper insight into the customer journey. By tracking conversions more accurately, you can see the path users take from seeing your ad to converting on your website. This can help you identify potential bottlenecks or drop-off points in the conversion process and make necessary adjustments to your website or ad strategy.


Lastly, Enhanced Conversions are designed with privacy in mind. The feature uses hashed first-party data, ensuring the privacy and security of user data during transmission. This means you can leverage the benefits of Enhanced Conversions while maintaining the trust and confidence of your users.

How does Enhanced Conversions work in Google Ads?

Enhanced Conversions work in tandem with conversion tracking in Google Ads to provide more accurate and detailed conversion data. Here’s how it works:

  • Data capture: When a user completes a transaction or fills out a contact form on your website, your conversion tracking tags capture first-party customer data such as an email address, name, home address, or phone number.
  • Data hashing: This data is then hashed using a secure one-way algorithm known as SHA256. Hashing transforms the data into a different form, ensuring the privacy and security of the data during transmission.
  • Data matching: The hashed data is sent to Google in its hashed form and then used to match your customers to Google accounts, which were signed in to when they interacted with one of your ads.
  • Conversion attribution: The resulting hashed data is then matched with logged-in Google accounts. It has resulted in attributing your campaign conversions to ad events such as clicks or views.
  • Reporting: You will receive aggregated conversion reporting. This gives you a more accurate view of how people convert after engaging with your ad.

How to Set Up Enhanced Conversions Tracking in Google Ads?

Setting up Enhanced Conversions in Google Ads is a simple process. In this section, I will walk you through 2 main options to set up Enhanced Conversions in Google Ads.

Option 1: Implement enhanced conversions using Google Tag Manager

Enhanced conversions supplement your existing conversion tags by sending hashed first-party conversion data from your website in a privacy-safe way. To set up enhanced conversions this way, you need to have conversion tracking already set up in the Google Tag Manager container you plan to use for enhanced conversions.

Step 1: Access to Conversions Actions

First, log in to your Google Ads account.

Once you’re logged in, look for the tools icon in the upper right corner of your Google Ads dashboard. Clicking on this icon will open a dropdown menu.

In the dropdown menu, you’ll see a section labeled ‘Measurement’. Under this section, click on ‘Conversions’. This will take you to the conversions page where you can see all your existing conversion actions.

After enabling Enhanced Conversions, you’ll be asked to enter some additional information. This includes the type of customer data you’ll be using (such as email addresses or phone numbers), and how you collect this data on your website.

Once you’ve filled in all the required information, click ‘Save’. This will save your changes and enable Enhanced Conversions for your chosen conversion action.

Option 2. Use options that require coding knowledge

Use code snippets

Add a code snippet on your website that transmits hashed client data for matching. This approach enhances the precision of enhanced conversions by guaranteeing that you consistently dispatch appropriately formatted data each time your conversion tag is activated.

Use CSS selectors or JavaScript variables

If you regularly update or change your website code, perhaps for formatting purposes, then it’s recommended that enhanced conversions are implemented with CSS or JavaScript instead. With this method, you can manually identify CSS selectors or JavaScript variables on your webpage that hold pertinent user-supplied data. This approach offers more accuracy than automatic detection, but it’s not as dependable as embedding code into your website.
