Compete Inc., a Boston-based web analytics company, has launched Behavior Match, a new tool designed for agencies, publishers, and online marketers, to improve the accuracy and efficiency of online marketing. Behavior Match uses data from the company's online consumer panel and divides it into different shopping and lifestyle categories. This helps marketers predict the best websites for their ad campaigns. The tool also helps marketers locate potential advertising opportunities on new sites and to determine the website sections that are most visited by their target audience. Behavior Match is delivered via an Excel-based reporting system.
