In order to help Publishers that dynamically create subdomains we have introduced functionality to setup this up with a few simple steps. You can configure your site so that all its subdomains will share the same tag and configuration with one entry in the Choice portal. On the "Create/Edit a site page" you add your main domain (e.x. myJournal.com) and then click the Apply to all my subdomains checkbox.
When this option is enabled a site specific tag is created. You can access that tag from the Choice Site List Dashboard using the menu entry GET TAG for the specific site.
Add that (site specific) tag to your main domain and all your subdomains, with which you like to share the same configuration with.
Note: To share consent across all your subdomain you will need also to configure the consent scope to be A group of your sites only. For details see section Group Consent.
Consent analytics are shared across the site and all subdomains using the same configuration. If you would like to have consent data broken out by the individual subdomains, download the log file (by selecting LOGS from the menu for the specific site).
