Enabling multiple domains for a test allows you to track goal conversions across multiple domains. For example, you have set up your test on www.example.com. Let us say one of the goals you define for the test is “visits a page,” which is tracked when the user lands on www.myexample.com.
As the test involves more than one domain, you must select the multiple domains option on the final step in the creation process. Enabling multiple domain options allows VWO to use third-party cookies to track visitors and goal conversions.
Things to Consider While you Enable Your Test to Run Across Multiple Domains:
- You need not enable cross-domain tracking for subdomains in your account.
- Do not enable cross-domain tracking if you have defined a ‘click on a link’ goal and the link points to a different domain, or if you have a ‘track form submits’ goal and the action URL is of a different domain.
- Cross-domain tracking must be enabled when the control and variation URLs in a Split URL campaign are of different domains.
- Cross-domain tracking is not supported for VWO Insights.
- For enhanced privacy, the Firefox and Safari browsers block cross-domain tracking by default. As a result, VWO cannot access the third-party cookies, thereby prohibiting cross-domain tracking from working in Safari and Firefox browsers. However, the default settings can be disabled using the following:
- In the Safari browser, go to Preferences > Privacy and disable the Prevent cross-site tracking setting.
- In the Firefox browser, go to Preferences > Privacy & Security > Custom and disable the following settings- Cookies and Tracking Content.
