VisiStat today added performance enhancements and new at-a-glance activity reports to VisiStat 4.0, its graphical website tracking service. The latest iteration of VisiStat features WorldMaps, a veritable GPS for website monitoring that allows users to see the source and volume of visits to a website from any country around the globe. VisiStat 4.0 also offers LinkTracker, a new feature that displays the number of document downloads and other clickable actions available on every page of a website. The application expands on its StatCaster real-time tracking technology, and features domain filtering which utilizes data authentication to prevent "spoofing." VisiStat 4.0 packages start from $20 per month.
