"Smart HitBot is an efficient program that can imitate the real surfers to read and click pages/banners online. Not only can it read and hit specified links, but also some dynamic links, even the links buried in pages. You can preset the time interval, the ratio of hits to impressions and the number of pages viewed per visit. Further more, Smart HitBot can change proxy and reference automatically, all these make it can perform more like the real surfers. "
