Tracking Subdomains in One Account
Hotjar fully supports cross-domain tracking for subdomains. This means that as long as the same Tracking Code is installed on each of the subdomains you want to track, Hotjar tracking will work as expected.
To set this up, install the same Tracking Code on all the subdomains you want to track under the same Site in Hotjar. You can get the Tracking Code from the Sites & Organizations page by clicking on the 'Tracking Code' button next to any Site you have set up.
Tracking Subdomains Separately
If you want to collect data for different subdomains separately you can also do this. Hotjar provides a unique Tracking Code for every Site you set up in your Organization. You will then need to install the different tracking codes on the different domains. You can read more in our Adding Sites to an Organization article.
Only users with admin access can create new Sites.
