What Is a Site Rotator and Why You Need It
A site rotator is software that picks an URL from a list (either randomly, or based on priority rules) and displays it to the visitor. Rotators are very useful when you want to promote multiple websites using a single URL or do some split testing. If you are a TE user, for example, and want to promote 50 splash pages while the exchange only allows up to 3 websites, you will want to use a rotator. Also, when adding a new URL, you will only have to do it in the rotator itself, and not in the 100s of traffic exchanges that you are a member of!
A sophisticated URL rotator will not only be able to rotate your sites randomly, but also assign priorities (so you can show selected pages more often), track statistics, and even filter domains (meaning if a visitor comes from “site A”, we do not show him pages that advertise “site A”, thus saving credits).
There are a lot of options when it comes to rotators. You can either host your own URL rotator script, or use one of the many online services. When choosing an online service, you usually want to make sure that the maximum number of URLs allowed is enough for you, and the additional features, such as hit tracking, are included.
