You can display various websites or pages to those who click on just one link by using a free URL rotator.  This means that you only need to generate traffic for a single link to promote several websites.  Promoting several websites, for example 100 sites, could be very hard.  Your promotional efforts would therefore be divided by a hundred when you use a free URL rotator or even by a larger number if you have 200 sites.  However, make sure that the provider of your free website rotator will not limit the number of URLs that you can submit for one rotator.  It would be advisable to search for a provider that will allow you to use an unlimited number of sites or URLs for only one rotator.

Another application of a free URL rotator is to allow you to easily transfer your focus to another product or service.  You can readily disregard a certain site by eliminating its URL from the list if you have only one link to market several sites.  The next step would be to insert the URL for the new service or product that you want to promote instead.  A free URL rotator makes this process hassle-free, as removing a product or service will not affect your traffic-generating activities.

Another potential use of a free URL rotator is to let a number of business owners participate in an advertising cooperative, where they will need to pay a certain amount to advertise their site via the rotator link.  Each member of the cooperative may also have to buy a share for each URL that he wants to show through the free URL rotator link.

Another creative way to apply the capabilities of a free URL rotator is the split-testing of a website. Some Internet marketers shy away from this procedure because it is difficult, but with a rotator, this is much simpler and easier.  All you need to do is to produce two similar versions of the page that will be subjected to split-testing and then change one element in the second version.  For example, if you want to determine the effect of increasing the size of the headline, you can enlarge the headline in the second version.  You then submit the URLs of these two versions to the free URL rotator and note the change in conversion rate.
