What Configuration Setting Eliminates Duplicate Conversions Between Advertisers?

Quick Summary

Duplicate conversions can skew your data and lead to inaccurate performance metrics in Google Ads. The "Conversion deduplication" setting, particularly through the use of order IDs or transaction IDs, helps in eliminating these duplicates. This blog post explores the causes of duplicate conversions, the role of the ORDER_ID deduplication parameter, how to set it up in Google Tag Manager (GTM), and best practices to ensure accurate conversion tracking across your advertising efforts.

Understanding Duplicate Conversions

Duplicate conversions occur when the same conversion action is recorded multiple times for a single event, leading to inflated conversion numbers. This can happen due to a variety of reasons:

• Multiple tracking scripts firing simultaneously.
• Improper setup of conversion actions in Google Ads.
• Users navigating back to the confirmation page and triggering the conversion script again.
• Cross-device or cross-browser tracking issues.

These inaccuracies can hinder your ability to make data-driven decisions regarding your advertising strategies.

The Role of ORDER_ID in Conversion Deduplication

The ORDER_ID or transaction ID is a unique identifier assigned to each transaction. By utilizing this ID, Google Ads can accurately detect and eliminate duplicate conversions. Here's how it works:

• When a conversion occurs, the ORDER_ID is sent along with the conversion data to Google Ads.
• Google Ads checks if the ORDER_ID has been processed before.
• If it hasn’t, the conversion is recorded. If it has, the conversion is ignored, thereby preventing duplicates.

How to Set Up ORDER_ID Deduplication in GTM

1. Ensure that your eCommerce platform generates a unique order ID for each transaction.
2. In Google Tag Manager, create a new Data Layer variable to capture the order ID.
3. Configure your Google Ads conversion tag to include the ORDER_ID variable. This can typically be done by modifying the conversion tag's settings to include your custom variable.
4. Test the setup thoroughly to ensure that the order ID is being correctly captured and sent with each conversion.

Testing for Duplicate Conversions

Testing is crucial to ensure that your deduplication setup is functioning as expected. Here are a few steps you can take:

• Simulate a Conversion: Complete a purchase on your site to see if the order ID is being correctly captured and sent.
• Use Google Tag Assistant: This tool can help verify if the tags are firing correctly and whether duplicates are being prevented.
• Check Google Ads Reports: Monitor your Google Ads account for any signs of duplicate conversions. The numbers should align with your actual sales data.

Additional Considerations for Accurate Conversion Tracking

Utilizing Auto-Tagging

Auto-tagging is a feature in Google Ads that appends the GCLID (Google Click Identifier) to your URLs. This helps in accurately tracking user interactions and conversions. For more insights, refer to our GCLID Explained blog post.

Cross-Account Conversion Settings

If you manage multiple accounts, cross-account conversion settings can help streamline the tracking process, ensuring consistent and accurate data across all accounts. This is particularly useful for agencies managing several clients under a single umbrella.
