Multiple hostname support is only available in Enterprise plans.
With multiple hostnames, you may track and serve personalization across various hostnames, managing your configuration all within a single account. A good example may be a parent company that has separate sub-brands and wants to keep segments and experiences persistent across all domains.
When logged into Persosa, access your account settings. From here, you'll be able to add new hostnames, remove old ones, and update the default editor URL (the URL that will open by default when you want to edit regions on a host).
To create a new hostname, simply click Add Hostname, enter the hostname string as well as the full URL (http/https included) of the page to open the editor to by default.
Persosa will perform substring matches for the hostname, so you may use the highest level you wish. For example, if your site is "www.foo.com", you may enter just "foo.com" to serve on any subdomain of "foo.com". If you are tracking across multiple subdomains (e.g., "www.foo.com" and "app.foo.com") and want to manage regions separately, you should enter them as separate hostnames. Do not enter "http://" or "https://" in this field.
When you've added all of your hostnames, click Save to save all changes.
Assigning a Hostname to Dynamic Regions and Styles
When creating a Dynamic Region or Style, choose the hostname you'd like to associate the region or style with. The content/rules you specify will then only be applied on the specified hostname. This feature can be used, for example, to change regions on one host, but not others.
What about Segments and Experiences?
Segments and Experiences are universal across all hostnames in your accounts. So, if a visitor falls into a Segment/Experience on one host, they will automatically be in those Segments and Experience on all other hosts they may visit within that account.
To delete a hostname, click Delete next to the appropriate hostname and then Save to save the changes. NOTE: Deleting a hostname will also permanently delete any dynamic regions or styles that were associated with it.
