The following free banner exchanges will randomly display your banner based on the number of times you show a banner for them. The ratiotells you how many times YOU have to display a banner in order for them to display yours -- for example, 2:1 means for each time you display 2 banners, they will show yours once. The size is the size of the graphic you must have to participate in their program. Examples of what a service's banners look like, and my comments on them, are available in the full reviews.
