Only a few years ago, businesses new to the World Wide Web were able to earn hundreds of thousands, even millions of dollars. They were able to do this through different marketing schemes, and by offering different products and services that no other business or company had been able to offer the online community. As word of the business boom spread, more businesses complemented their brick and mortar establishments with virtual ones, further crowding the Internet marketplace.

The online boom, however, is slowly becoming an online thud. With the abundance of businesses offering the same products and services, small and medium sized corporations are finding it difficult to penetrate into the market. Large corporations, with their commercial and financial clout, are able to widen their market reach easily, while smaller groups of companies try to make their voice heard in the noise of the Internet.

A solution to this exists in the form of the affiliate program, where lesser known companies can come together and help each other market their goods and services. More specifically, the affiliate program pays commission to its affiliates whenever anything is brought to the main site through the efforts of the affiliate. These can come in the form of website visitors, clicks on an advertisement, new registrants at the main site, or purchases at the main affiliate site.

Affiliate programs give like-minded businesses a chance to come together and promote each other. Such programs will usually bring together businesses with the same goods and services. The most popular sectors in today's affiliate marketing programs are those that cater to adult sites, retail businesses, and the gambling sector. Also in the process of growth and expansion are affiliate marketing programs for the travel sector, finance websites, and the mobile phone market.

If you are the owner of a small to medium-sized business, then affiliate marketing may work for you. You can link to other small and medium-sized businesses in your field and earn commissions depending on how you are able to contribute to the affiliate program. All you need to do is allow a part of your website to post advertisements promoting affiliates, and you can earn money through them. There are a variety of ways by which you can be paid commissions.

The advertisements that will be posted on your site will not be stagnant. Although the advertisements will always be in the same place, they will change. For every one thousand displays ? or impressions ? of a certain advertisement, you will receive compensation. This scheme is known as Pay Per Impression. Advertisements can come in the form of text, an image, or even a streaming video.

If a visitor to your site clicks on the advertisement, then you may be given a commission. In Pay Per Click, you will receive payment every time the advertisement is clicked, regardless of how often the advertisement is displayed.

If a visitor registers for the services of the main affiliate site through the efforts of your site, then you can also be given commissions for the referral. This scheme, known as Pay Per Lead, allows you to earn money every time a customer does something important for the main affiliate site. This may include filling out an online form, signing up for a free account at the main site, or subscribing to the site's newsletter.

Perhaps the most lucrative scheme is the Pay Per Sale, or commission on customer purchases. Also known as the Revenue Sharing scheme, this scheme allows you to receive a percent of the order made by a customer.

Pay Per Call is an emerging scheme, and links up Internet businesses with their brick and mortar counterparts. In Pay Per Call, you can be awarded commissions for every call made to the main affiliate site after a referral from an advertisement on your site. This is possible due to recent developments in the technology of call tracking.

If you are interested in making your business expand online, then you may want to consider affiliate marketing, and joining an affiliate program. Be warned, however, that profits are not easy to come by in an already crowded Internet marketplace. With the right advertisements, and with the right affiliate program, however, you may be able to earn money and make your business prosper.
