Affiliate Program - An advertising program offering a monetary incentive for webmasters to drive traffic to the advertiser's website. This eliminates the necessity for the advertiser to find websites with related content to list their banners. It also increases the response rate by giving the "affiliate" websites a stake in the response rate. Affiliate programs are a great plan for the websites offering them, but the websites that participate often become underpaid sales representatives.
