Techopedia explains Banner Rotator
Banner rotator software loads banner advertisements and rotates them while website visitors are on a website. Banner rotator software prevents banners from becoming stagnant, thus making them more noticeable to a website's visitors. Banner rotator programs typically also give Web publishers options such as how often certain banners will be displayed and where they will be displayed on a given Web page.
The term is generally only used in the context of a small website. Larger we publishers would use a more sophisticated ad-serving system. While it used to be that the technology to serve ads could be provided in a small script, modern day publishers need much more advanced tools to better target ads to site visitors.
