Tracking leads on multiple domains is possible on Growth and above plans. Multiple domains can be tracked using the same tracking code that is used for your primary website. Now, your dashboard will show cumulative results.
If you want to separate results based on different domains, you will have to create Segments. Use the data filter URL Contains and insert the domain of your website and create different segments for each domain you want to track separately.
You can do the same thing while using Salespanel Reports. Use URL Contains filter on the Reports page to generate data of individual domains.
If you want to track different domains using separate accounts that have a common billing plan, please get in touch with us.
