This service is for businesses that have short sales cycles and may also operate with the strategy of high volume low margins. A Variable Fee Advertisement service, such as this, is effectively the best product for the business model. The advertisement placement offers a low fee, customer-specific display-frequency, and bills fees in proportion to the frequency of exposure - effectively per impression per site-visitor per visit

In general, this service is particularly suited to business that must create an  impression in the customers mind to motivate almost immediate purchase. Advertisement expenses therefore are generated by such sales over short periods of time, hence effectively focusing on customer exposure frequency.
