How Can an Advertiser Set Up Enhanced Conversions for Web?

Google Ads is always evolving to help you get the most from your marketing budget, especially as privacy regulations and cookie limitations become more important. One powerful tool now at your fingertips is Enhanced Conversions for web. But what are enhanced conversions, why should you care, and—most importantly—how can you set them up for maximum impact? Let’s break it down step by step.


What Are Enhanced Conversions for Web?

Enhanced conversions for web allow you to improve the accuracy of your conversion tracking in Google Ads. Instead of relying only on cookies, they use hashed first-party customer data from your website. This extra signal helps Google match conversions back to your ads, even as traditional tracking becomes less reliable.

In simple terms: Enhanced conversions help you see which ads led to real customer actions (like purchases or sign-ups), even if someone uses different devices or blocks cookies.

  • Future-proofing: Stay ahead as privacy rules and browser changes limit existing tracking solutions.
  • Retain insights: Get clearer attribution for your marketing spend.

Getting Ready: What You’ll Need

Before you dive in, make sure you have:

  • A Google Ads account with conversion tracking set up.
  • Access to your website’s code or a tag management system (like Google Tag Manager).
  • The ability to capture customer data at conversion (like email, phone, or name) on your site’s thank-you page.
  • The right privacy disclosures on your website.

Step-by-Step: How to Set Up Enhanced Conversions for Web

There are two ways to set up enhanced conversions: using Google Tag Manager or directly via the Google Ads tag. Here’s how you can get started.

1. Set Up with Google Tag Manager

Google Tag Manager (GTM) is the preferred choice for many, as it keeps things organized and code-free. Here’s how:

a. Enable Enhanced Conversions in Google Ads

  • Sign in to your Google Ads account.
  • Click on “Tools & Settings” > “Measurement” > “Conversions.”
  • Select your existing web conversion action or create a new one.
  • Scroll down to “Enhanced conversions” and select “Turn on enhanced conversions.”
  • Save your changes.

b. Configure in Google Tag Manager

  • Open GTM and choose the web container for your website.
  • Find your conversion tag (usually called “Google Ads Conversion Tracking”).
  • In the tag settings, enable “Enhanced Conversions.”
  • Map the customer data fields. GTM should pull this data from your thank-you page’s data layer, variables, or page elements.
  • Publish your changes.

Tips for Success:

  • Test your tag implementation with GTM’s Preview mode.
  • Use the Tag Assistant tool to confirm data is sent to Google.

2. Set Up with the Google Ads Tag (Manual Setup)

If you’re not using GTM, you can implement enhanced conversions directly into your website’s code:

  • Identify the customer data (email, phone, etc.) on your conversion page.
  • Hash the data using SHA-256 (this can be done with JavaScript).
  • Add the enhanced conversions parameters to your existing Google Ads conversion script.

Note: This approach usually requires developer help.


Mapping Customer Data: What Information to Send

For enhanced conversions to work, your website must collect at least one piece of first-party customer data at the point of conversion, such as:

  • Email address
  • Phone number
  • First and last name, along with home address

This information is never transferred as plain text. It’s securely hashed in your browser before sending to Google, protecting privacy every step of the way.


Testing and Troubleshooting

Don’t rush! After setup, always:

  • Use Google Tag Assistant and Tag Manager’s debug mode to verify the tags fire correctly.
  • In Google Ads, check the “Status” column on your conversion action for enhanced conversions to ensure active data is being received.
  • Expect full reporting to begin a few days after setup.

Common issues to check:

  • Are customer data fields available and accurate on your conversion page?
  • Is the hashing function working (if implemented manually)?
  • Have you notified your users according to privacy regulations?

Benefits of Enhanced Conversions

Once live, enhanced conversions offer several advantages:

  • More complete data: They help “fill in the gaps” when standard conversion tracking misses a match.
  • Boosted automation: Your Smart Bidding algorithms get better feedback for optimization.
  • Actionable insights: You get a clearer picture of what’s working.
  • Peace of mind: You stay compliant and ahead of privacy changes.

Challenges and Considerations

While enhanced conversions are powerful, here are a few potential challenges:

  • Data quality: Make sure customer data is consistently available and accurate at conversion.
  • Technical setup: Manual implementation requires technical skill.
  • Privacy: You must clearly communicate data practices and privacy disclosures to your site visitors.
  • Lag time: Enhanced conversion reports might take a few days to populate.

Best Practices for Enhanced Conversions

To ensure you get the most from this feature, follow these best practices:

  • Automate with GTM: Use Tag Manager to minimize manual errors and give you more control.
  • Capture quality data: Ensure your forms ask for and validate necessary information (like email or phone).
  • Regularly test: Periodically verify your setup as your website changes.
  • Review privacy policies: Keep users informed on how their data is used and protected.
  • Monitor performance: Check Google Ads regularly for any alerts or suggestions.

Practical Tips for Advertisers

  • If you’re new to conversion tracking, enhanced conversions can dramatically improve your data quality from day one.
  • For e-Commerce, make sure your checkout and thank-you pages collect usable data (like email addresses) at each conversion.
  • For lead generation, adapt your web forms to capture at least one piece of matching customer data.
  • You can program your tags to collect only the data you need, minimizing what’s shared.
  • Always hash data in-browser—never send raw customer info.

Cost Considerations

Setting up enhanced conversions itself is free through Google Ads and Google Tag Manager. However, consider these indirect costs:

  • Development time, if you need help from your web engineer or tag management expert.
  • Potential investments in tag management tools or plugin upgrades.
  • Ensuring your privacy policy covers the new data usage.

The value you gain in more accurate conversion measurement and improved ad performance often far outweighs these setup costs.


Summary

Enhanced conversions for web are a must-have for modern Google Ads advertisers. They unlock more accurate measurement, power smarter bidding, and help you adapt to a privacy-first world.

Here’s what you need to remember:

  • Enhanced conversions use hashed, first-party data to boost your conversion tracking.
  • Setup is straightforward with Google Tag Manager or can be done directly in-code.
  • Capture accurate, quality data and rigorously test your setup.
  • Stay transparent and up-to-date on privacy practices.
  • The payoff: more conversions tracked, better return on ad spend, and future-proofed measurement.
