Bango has added a new feature to its Bango Analytics toolset that helps advertisers determine the value of a mobile campaign.

According to Mobile Entertainment, the new Bango User ID technology tracks visitors to a mobile site and any actions they take, such as downloading content or making a purchase. This allows marketers to track which sources deliver the most traffic and which deliver the best return on investment.

Bango Analytics is a hosted service that marketers can try at www.bango.com/analytics.
