Streams Online Media Development, Chicago, said its Lilypad Web tracking tool is now commercially available. Lilypad tracks the effectiveness of Web hyperlinks by determining how users got to a particular site and when they came. The tool is targeted to ad agency media buyers and others who want to assess the performance of both paid and unpaid links. The software costs $695 per month plus a $500 installation fee.
