DoubleClick Inc. on Monday launched an upgrade of its multi-channel analytics tool, which has been enhanced with the ability to track online sales across up to six sales channels.

In addition, ChannelView 2.0 includes performance improvements in the user interface and enhanced reporting capabilities.

ChannelView was launched in 2002 to enable marketers to identify how campaigns are driving customers to purchase through websites, call centers or retail stores. The upgrade includes the added ability to break out sales between retail and outlet stores, catalogs and gift registries.

"The version 2.0 release expands the capabilities of ChannelView in order to manage the increasing complexity of multi-channel marketing," John Black, senior product manager at Abacus, a division of New York-based DoubleClick, said in a statement.

Through a single interface, the ugrade enables marketers to understand and manage the interaction between direct mail, paid search, affiliate marketing and e-mail-marketing programs, Black said.
