Urchin software could be run in two different data collection modes: log file analyzer or hybrid. As a log file analyzer, Urchin processed web server log files in a variety of log file formats. Custom file formats could also be defined. As a hybrid, Urchin combined page tags with log file data to eradicate the limitations of each data collection method in isolation.^[2] The result was more accurate web visitor data.^[3]

Urchin became one of the more popular tools for website traffic analysis, particularly with ISPs and web hosting providers. This was largely due to its scalability in performance and its pricing model.^[4]
