Cooperative Advertising
Recently, cooperative advertising “networks” have popped up on the internet. Basically, a cooperative is a community based advertising network that distributes ads among its members with no fee. The “fee” is the ad space, you as a member, give up on your website(s). Some of the networks are themed and some are just general advertising networks that do not differentiate between a real estate website and a shopping portal. Many times the networks are based on the number of pages a particular search engine has in their index of a particular site. Others use impression based technology to “level the playing field.”
However the coop is built, they are fast becoming a new way for people to distribute advertisements and links across a large number of websites.
