What is the purpose of the url rotator?

I'm trying to use the URL rotation tool to promote my site, but it seems like the same page is running continuously on the same page on my computer and that the traffic is not running on the same page. not increase at all, because it is not a single IP address.

So my question is, what is the point of using Rotator and why do people create it? Sorry, this may not be the place to ask but I'm not sure where this question is supposed to be asked
