Affiliate marketing is quite simple to explain: you promote and market a product or company in return for a commission if a sale or lead is made from your marketing efforts. With online affiliate marketing you simply place your affiliate ID embedded links on your web pages and if a customer clicks your link and proceeds to that designated company’s site and makes a purchase or signs up for a service, you earn a commission.

Affiliate marketing, if done right, can prove to be a very lucrative venture. Commissions can run anywhere from a few pennies to thousands of dollars for just one click or sale. Professional marketers develop affiliate relationships with hundreds of companies and build sites to promote these companies and products.

Needless to say, the advent of the Internet has been a golden opportunity for affiliate marketers to really expand their promotions and marketing. As more as more customers choose to buy online, advertising and purchases keep increasing at a maddening pace.

To accommodate all this online ecommerce we have seen the birth of large affiliate networks, operated by large corporations. Make no mistake, affiliate marketing is big business, accounting for billions in sales and commissions.
