You can choose to view reports by different counting methodologies to understand how your activities affect your users across their lifetimes or during a single session.
Counting methodology is supported for the following activity types:
As an exception, Auto-Target A/B activities support only the default "Visit" counting methodology.
Experience Targeting (XT)
Multivariate Test (MVT)
For the MVT Element contribution report, Target does not support Activity Impressions for Revenue Metric types.
Only the default counting methodology (Visits) is currently supported for Automated Personalization (AP) activities.
You can view reports by the following counting methodologies:
A person will be counted as a new entrant if he or she visits the site from a new computer or a new browser; deletes the cookie; or converts and returns to the activity with the same cookie. An entrant is identified by the PCID in the visitor's mbox cookie. If the PCID changes, the person is considered a new visitor.
If a conversion is achieved or a visitor comes back to the site after being away at least 30 minutes, a returning visitor counts as a new visit. A visit is identified by the sessionID in the visitor's mbox cookie. When the sessionID changes, the visit is considered new.
A single visit might include several impressions of, for example, your homepage.
