In the dynamic world of ecommerce growth, having a clear understanding of user behavior across different domains is essential. Setting up cross-domain tracking between your ecommerce site and blog allows you to consolidate data and gain comprehensive insights into user interactions. In this comprehensive guide, we’ll walk you through the process of setting up cross-domain tracking, empowering you to harness the power of analytics for enhanced {ecommerce growth}.

The Power of Cross-Domain Tracking

Before we dive into the details, let’s explore why cross-domain tracking matters. If your ecommerce site and blog exist on separate domains, tracking user behavior across both platforms individually can lead to fragmented data. Cross-domain tracking bridges this gap, allowing you to view user journeys seamlessly and make informed decisions that drive strategic success.

Step 1: Prepare Your Google Analytics Account

Question: What Do I Need to Do First?

  1. Access Your Google Analytics Account: Log in to your Google Analytics account, and navigate to the property for which you want to set up cross-domain tracking.
  2. Enable Cross-Domain Tracking: In the property settings, find the “Tracking Info” section and click on “Tracking Code.” Enable “Enable Cross-Domain Tracking.”

Frequently Asked Questions

Q1: Can I track subdomains with cross-domain tracking? Yes, cross-domain tracking works for both main domains and subdomains. You can track user interactions across various subdomains as well.

Q2: Will cross-domain tracking affect my existing data? Cross-domain tracking doesn’t affect historical data. It enhances future data collection by linking user sessions across domains.

Q3: Do I need to change my tracking code for cross-domain tracking? Yes, you need to make adjustments to your tracking code and configuration settings to enable cross-domain tracking.

Step 2: Update Tracking Code on Both Domains

Question: What’s the Next Step?

  1. Gather Your Tracking Code: Retrieve the Google Analytics tracking code from the property where cross-domain tracking will be implemented.
  2. Implement Tracking Code on Your Blog: Paste the tracking code snippet on every page of your blog, just before the closing “</head>” tag.

Step 3: Configure Cross-Domain Tracking

Question: How Do I Configure It?

  1. Identify Domains to Track: Decide which domains you want to track together. In this case, your ecommerce site and blog domains.
  2. Add Domains to Referral Exclusion List: In your Google Analytics property settings, find the “Tracking Info” section and click on “Referral Exclusion List.” Add both domains to prevent self-referrals.

Step 4: Modify Links with Linker Parameters

Question: What Are Linker Parameters?

  1. Generate Linker Parameters: Google provides a tool that generates linker parameters. This tool appends special query parameters to your URLs to enable cross-domain tracking.
  2. Implement Linker Parameters: For each link that leads from your ecommerce site to your blog (or vice versa), append the generated linker parameter to the URL.

Step 5: Test and Validate

Question: How Do I Ensure It’s Working?

  1. Use Real-Time Reports: After implementing cross-domain tracking, use the Real-Time reports in Google Analytics to test if your data is being tracked accurately.
  2. Check User Journeys: Review user journeys in the Behavior reports to confirm that sessions are tracked across both domains.


Setting up cross-domain tracking between your ecommerce site and blog is a strategic move that fosters a comprehensive view of user behavior and fuels ecommerce growth. By preparing your Google Analytics account, updating tracking code, configuring cross-domain settings, modifying links with linker parameters, and testing your implementation, you equip yourself with the tools to seamlessly integrate data and drive strategic success.
