How many types are in affiliate marketing?

Different advertisers offer different types of affiliate programs. If you join a search engine affiliate program you most likely will be placing text links or banners to their advertisers and you'll work on a pay-per-click fee. E-mail list affiliates promote e-mail newsletters and are usually paid when a person joins the advertised opt-in e-mail list. Being an affiliate of any merchant usually means you are paid a commission per sale on the advertiser's Web site. Generally speaking,  pay-per-click affiliate programs pay the least amount, as affiliates are often paid per thousand clicks (CPC).

•                Pay-per-lead programs are when you provide the links to downloads, trial offers, and e-mail opt-in lists and so on. Depending on the advertiser, you may be paid per lead generation or you may not be paid unless the user subscribes and pays for a full service from the advertiser. Again, you may also receive fees for both instances.
•                      Pay-per-sale affiliate programs (also called revenue sharing) usually offer the highest commissions, and you'll typically receive a set dollar amount per sale or a straight percentage of the total sale. Because a user has to purchase something, you may find this program best-suited to high-traffic affiliate sites.

What is affiliate marketing?

•                                        If you have a Web site or blog and are looking for a way to earn income from your online property, consider affiliate marketing programs.

•                                     Affiliate marketing is the term used to describe a revenue-sharing plan where an online automated marketing program lets Webmasters place an advertiser's banner ads or buttons on their own Web site. Webmasters will receive a referral fee or commission from conversions when a customer has clicked the affiliate link and performs the desired action, such as make a purchase or opt-in for downloads or newsletters on the advertiser's site. Advertisers invest in affiliate programs for lead generation, and, of course, sales.

Affiliate marketing at its very core is about relationships,

a relationship between three parties: 

•                                   Not all affiliate plans work in the same way or pay the same rates. Some enable you to place text or image hyperlinks to products or a Web site, others allow you to set up a shopping or store page that offers products related to the content of your Web site, and others require you to simply place general advertising banners or buttons
