What is the purpose of URL rotator?

I've trying to use URL rotator tool to promote my site but it seems it keeps rotatoing the same page all over on my computer and the traffic does not increase at all because its me myself not unique IP.

So my question is what is the point of using rotator and why people creating it. Sorry this may not be the place to ask but i am not sure where this question is suppose to be place
