The advertising company sets the terms of an affiliate marketing program. Early on, companies largely paid the cost per click (traffic) or cost per mile (impressions) on banner advertisements. A technology evolved, the focus turned to commissions on actual sales or qualified leads. The early affiliate marketing programs were vulnerable to fraud because clicks could be generated by software, as could impressions.
Also known as a publisher, the affiliate can be either an individual or a company that markets the seller’s product in an appealing way to potential consumers. In other words, the affiliate promotes the product to persuade consumers that it is valuable or beneficial to them and convince them to purchase the product. If the consumer does end up buying the product, the affiliate receives a portion of the revenue made.
Si miras detenidamente, la generación de prospectos es muy similar al trueque, donde las personas intercambian su información de contacto por algo valioso como un libro electrónico, una consulta, cupones de descuento o un seminario web. La única diferencia es que compartir información de contacto no es exactamente como separarse de tu gallina, y obtener un libro electrónico no es tan valioso como obtener madera. Pero, todavía es comercio.
A more complex system, pay per lead affiliate programs compensates the affiliate based on the conversion of leads. The affiliate must persuade the consumer to visit the merchant’s website and complete the desired action — whether it’s filling out a contact form, signing up for a trial of a product, subscribing to a newsletter, or downloading software or files.
Spam is the biggest threat to organic search engines, whose goal is to provide quality search results for keywords or phrases entered by their users. Google's PageRank algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.
