In April, 2009, the director of media strategy at henderson bas, a Toronto-based online advertising agency, was evaluating the current campaign for Primus Telecommunications (Primus). It had been two months since the Primus home phone bundle banner advertisement campaign had been launched, and initial results were not as expected. While there were a lot of visitors attracted to the Primus website, those visitors were not converted into paying customers at a high enough rate. This poor conversion rate had pushed the cost per acquisition of new Primus customers to uncomfortably high levels, threatening the campaign's future. By gathering form usage data from the website and subsequently implementing visitor-tracking software, the director focused her attention to analyze the results to determine why visitors to Primus' website were not converting into paying customers.
