Ad Placement
Ad placement is similar to pay-per-performance in that you pay for advertisements on sites or newsletters. The difference is that you typically pay for impressions and market reach. Impressions encompass how many unique visitors view the location in which your ad is placed. The market reach refers to the number of individuals accessing that website or newsletter over a period of time. However, you have no guarantee of the number of visitors who will follow your ad to your website. The concept is similar to traditional print ad placement in that advertisers have no guarantee that people exposed to their print ads will visit their places of business.
Joint Ventures
Another method, joint ventures, can be highly effective in helping businesses obtain referral customers. Joint ventures can be as simple exchanging links with another website or as complex as assembling a tiered affiliates program
