What are Enhanced Conversions in Google Ads?

Enhanced conversions are a powerful feature in Google Ads that help improve the accuracy of conversion tracking by using first-party data. This feature is designed to address the challenges posed by increasing data privacy regulations and the phasing out of third-party cookies.

How Enhanced Conversions Work

Enhanced conversions use a process called hashing to encrypt first-party data such as email addresses, phone numbers, or home addresses. This data is then matched with signed-in Google accounts to attribute conversions more accurately.

Here's a simple breakdown of the process:

  1. Data Collection: When a user interacts with your website and completes a conversion action (like making a purchase or filling out a form), their first-party data is captured.
  2. Hashing: This data is then hashed using a one-way encryption algorithm called SHA256. Hashing converts the data into a unique string of characters, ensuring it remains secure and private.
  3. Data Transmission: The hashed data is sent to Google.
  4. Matching: Google cross-checks the hashed data with its own database of signed-in Google accounts.
  5. Attribution: If a match is found, the conversion is attributed to the corresponding ad event, such as a click or view.

This process enhances the accuracy of conversion tracking while maintaining user privacy.

Types of Enhanced Conversions

Enhanced conversions come in two main types: Enhanced Conversions for Web and Enhanced Conversions for Leads.

Enhanced Conversions for Web

This type is ideal for tracking online sales, sign-ups, or other actions that take place directly on your website.

Example:- A user clicks on your ad and lands on your website.- They make a purchase.- The conversion tag captures their data and sends it to Google.- The hashed data is matched with Google accounts, and the conversion is attributed to the ad.

You can set this up using Google Tag Manager, Google tag, or the Google Ads API.

Enhanced Conversions for Leads

This type is designed for businesses that generate leads through form submissions or other means.

Example:- A user clicks on your ad and fills out a form on your site.- Their lead details are stored in your Customer Relationship Management (CRM) system.- You upload this first-party data to Google.- Google matches the hashed data with its user data, attributing the conversion to the ad.

This can also be set up using Google Tag Manager or Google tag.

By implementing these enhanced conversions, you can significantly improve the accuracy of your conversion data, optimize your bid strategies, and ensure compliance with data privacy regulations like GDPR and CCPA.

Next, we’ll dive into how to set up enhanced conversions for your business.

Setting Up Enhanced Conversions for Your Business

Enhanced Conversions for Web

Enhanced conversions for web allow you to capture more accurate conversion data directly from your website. This setup can be done using Google Tag Manager or the Google tag.

Google Tag Manager:1. Open Google Tag Manager and select your account.2. Navigate to Tags and create a new tag.3. Choose Google Ads Conversion Tracking as the tag type.4. Enable Enhanced Conversions and specify the data to be captured, such as email addresses.5. Configure the trigger to fire on the conversion page (e.g., order confirmation page).6. Publish your changes.

Google tag:1. Access your website’s code and locate the existing Google tag.2. Modify the tag to include the enhanced conversions parameter.3. Add JavaScript to capture user data (like email addresses) and hash it using SHA256.4. Ensure this script runs on your conversion pages.5. Save and test your changes.

Data Capture:- Enhanced conversions use hashed user data (e.g., emails) for privacy.- This data is then matched with Google accounts to attribute conversions accurately.

Enhanced Conversions for Leads

Enhanced conversions for leads help track conversions that happen offline, such as when a lead from your website becomes a customer later.

Lead Forms:1. Activate lead form ads in your Google Ads account.2. Google captures user-provided data directly from the form, so no additional tagging is needed.

CRM Integration:1. Collect lead information (e.g., email addresses) from your website forms.2. Store this data in your CRM system.3. When a lead converts, upload the hashed data to Google Ads.4. Google matches this data back to the original ad click.

Offline Tracking:- This method does not require modifying your lead forms to capture Google Click IDs (GCLIDs).- Instead, it uses existing data like email addresses, making it easier to set up.

Google Ads API:1. For more flexibility, use the Google Ads API to send enhanced conversion data.2. This method allows for custom data handling and integration with your systems.

By setting up enhanced conversions for web and leads, you can improve the accuracy of your conversion tracking, optimize your campaigns, and better align with privacy regulations.

Next, let's explore the benefits of using enhanced conversions in Google Ads.

Benefits of Using Enhanced Conversions in Google Ads

Impact on ROI

Enhanced conversions in Google Ads can significantly boost your return on investment (ROI). When you use this feature, you get more accurate data on user interactions. This means you can see exactly how many conversions your ads are driving, even if users switch devices or browsers during their journey.

For example, one client saw a 25% improvement in conversion rates and a 40% decrease in average cost-per-lead after enabling enhanced conversions. This improved accuracy helps you allocate your ad spend more effectively, ensuring that every dollar spent is driving real results.

Compliance with Data Privacy Regulations

Data privacy is a big deal. With laws like GDPR and CCPA, companies must be careful about how they collect and use personal data. Enhanced conversions use hashed first-party data, which means the data is encrypted before it's sent to Google. This keeps user information safe and compliant with privacy regulations.

GDPR requires companies to get explicit consent from users before collecting their data. It also allows users to access, delete, or modify their data. Enhanced conversions meet these requirements by encrypting data using SHA256, a secure one-way algorithm.

CCPA gives Californians more control over their personal data. It requires companies to disclose what data they collect and allows users to opt out of data sales. Enhanced conversions align with these rules by using first-party data that is securely hashed and anonymized.


Enhanced conversions provide a more accurate picture of your ad performance. By using first-party data like email addresses and phone numbers, Google can match conversions to user accounts more reliably. This reduces discrepancies and ensures that all relevant conversion events are tracked and attributed correctly.

Bidding Optimization

Accurate conversion data is crucial for effective bidding strategies. With enhanced conversions, Google Ads can make better-informed decisions about how much to bid for each ad placement. This means your automated bidding models, like tROAS and tCPA, get better data, leading to improved performance and higher ROI.


Enhanced conversions are designed with privacy in mind. By hashing user data before it's sent to Google, this feature ensures that personal information remains secure. This approach balances the need for accurate conversion tracking with the growing demand for data privacy.

Conversion Tracking

Enhanced conversions capture more conversion data than traditional methods. This is especially important as third-party cookies become less reliable. By using first-party data, you can track conversions more accurately, even in a cookie-less world.

Campaign Performance

Better data leads to better decisions. With enhanced conversions, you get a clearer view of which ads are driving results. This allows you to optimize your campaigns more effectively, leading to better performance and higher ROI.

In summary, enhanced conversions in Google Ads offer numerous benefits, from improved accuracy and bidding optimization to compliance with data privacy regulations. By embracing this feature, you can elevate your ad performance and achieve better results.

Next, let's tackle some frequently asked questions about enhanced conversions.

Frequently Asked Questions about Enhanced Conversions

Should I Turn On Enhanced Conversions in Google Ads?

Yes, you should consider turning on enhanced conversions in Google Ads. Enhanced conversions provide more accurate conversion data by using hashed user data to match conversions to Google accounts. This means you can catch conversions that might otherwise go untracked, improving your overall data quality.

One user on Reddit mentioned that without enhanced conversions, "You will just see less conversion data in your ad accounts." This means more accurate data, leading to better campaign performance and ROI.

Enhanced conversions are especially important as third-party cookies are phased out. They ensure you still get valuable conversion data, helping you make informed decisions about your ad spend.

What is the Difference Between Enhanced Conversions and Enhanced Conversions for Leads?

Enhanced Conversions and Enhanced Conversions for Leads serve different purposes:

  • Enhanced Conversions for web track online purchases and actions directly on your site. They capture user data at the point of conversion, such as a purchase confirmation page.

  • Enhanced Conversions for Leads focus on tracking conversions that happen offline. For example, if someone fills out a form on your site and later becomes a customer, this data can be uploaded to Google Ads. This helps attribute offline conversions to your online ads.

In both cases, data is hashed and matched to Google accounts to ensure privacy and accuracy.

What are the Requirements for Enhanced Conversions?

To set up enhanced conversions, you need to make some modifications to your existing tags. Here are the basic requirements:

  1. Tag Modifications: You need to slightly configure your current conversion tags. This can be done using Google Tag Manager, the Global Site Tag, or the Google Ads API.

  2. User Data: You must capture and send user data such as email addresses, phone numbers, or addresses. This data is hashed using SHA256 before being sent to Google, ensuring it remains secure.

  3. Compliance: Ensure you comply with data privacy regulations like GDPR and CCPA. Google requires you to confirm compliance before enabling enhanced conversions.

By meeting these requirements, you can set up enhanced conversions and start benefiting from more accurate conversion tracking.

Next, let's wrap up everything we've learned about enhanced conversions and look at their future in digital advertising.


The future of advertising is rapidly evolving, and enhanced conversions in Google Ads are at the forefront of this transformation. By leveraging enhanced conversions, businesses can achieve a more accurate picture of their ad performance, leading to better-informed decisions and optimized campaigns.

Future of Advertising

As third-party cookies become less reliable due to browser updates like Safari's ITP and Firefox's ETP, first-party data solutions like enhanced conversions will become increasingly vital. Enhanced conversions help bridge the gap by using hashed first-party data to match conversions with Google accounts, ensuring more accurate tracking while respecting user privacy. This shift towards privacy-centric tracking methods is not just a trend but a necessity for the future of digital advertising.

Strategic Implementation

Implementing enhanced conversions requires a strategic approach. Businesses should start by reviewing and complying with data privacy regulations such as GDPR and CCPA. Next, setting up enhanced conversions through tools like Google Tag Manager or the Google Ads API is crucial. By doing so, businesses can capture and hash first-party data securely, ensuring compliance and accuracy.

Enhanced conversions also enable better bidding strategies. With more precise conversion data, advertisers can optimize their bids and improve their return on ad spend (ROAS). This incremental improvement, much like the British Cycling Team's philosophy of "incremental gains," can lead to significant performance boosts over time.
