Interest mapping systems and/or methods determine areas of interest on a web page or other information resource based on the time a user spends in various scroll positions on the page. The system identifies scroll positions on a web page that are maintained for at least a predetermined period of time. The system may further generate one or more interest maps for web page or other information resource indicative of those areas of the web page which seem to be of relatively more or less interest to users. The system may further generate trend data for the web page based on the scroll position data over time.
