Cross and Sub Domain Funnels
Conversion experiment funnels most typically occur under a single domain, e.g. www.metropolclothing.com. Sometimes, they span across multiple sub-domains, e.g. www.metropolclothing.com and secure.metropolclothing.com. In other cases, the funnel may span across completely different domains, such as www.metropolclothing.com and www.metropolclothingecommerce.com.
Following is an example of the option to include all subdomains in a URL matching pattern. This can be found under "Advanced Options" in the Add Page modal:
Benefits of the new feature
- Cross and sub-domain funnels are supported without requiring any Ascend assistance.
- Experiment setup behaves no differently for cross, sub, or single domain funnels -- Ascend will resolve cookie domain scoping automatically.
How it works
By default, Ascend tracks users within experiments through the use of 1st party cookies. When a user returns to a page they have previously visited, Ascend recognizes them, as well as the experiment and candidate ids they had previously participated in. However, 1st party cookies do not support cross-domain funnels.
To this end, for those experiments which cross domains, the same information is stored in a 3rd party cookie accessible by all sites participating in the funnel, regardless of the domain. Same-domain experiments will continue to use first party cookies.
Page Editor UI
To support cross-sub-domain and cross-domain funnels, the page editor UI has been updated as follows:
Rather than having the site sub-domain and domain being statically hard-coded in the UI, a funnel page URL may simply be copied/pasted directly from a browser window URL field. If it differs from the domain of the experiment, a notification is displayed:
The same approach is taken with adding a conversion goal:
Cross sub-domain and domain funnels are an important feature, empowering sophisticated CRO experiments. Please reach out to your Ascend customer success representative or contact email@example.com regarding any related questions or requests.
