Affiliate Internet programs have been used by many online entrepreneurs to develop a secondary and some times main source of income.

Affiliate programs have increased in popularity because of the online marketing tools that are increasingly available to affiliates.

While in the past an affiliate had to resort to spending hundreds of dollars to bring visitors to his affiliate link, there are now plenty of tools that will enable him to bring these visitors for free.

For starters, an affiliate can build a content rich website. A content rich website can attain many natural, or free, search engine listings.

When surfers see the listing they can click on it and visit the affiliates site.

This is traffic is completely free, and therefore very lucrative to the affiliate.

Another tool is in the form of free advertising software. This software will allow an affiliate to place millions of ads for free with a click of a button.

Sites such as www.billionfreeads.com offer software that automates the process. An affiliate can now use this software to promote as many of his affiliate programs as he wants, and as often as he wants.

Other tools that affiliates can use are pay per click search engines such as Overture and Google.

While there is nothing new about these search engines, what is new is the lower minimum bidding introduced by Google.

An affiliate can now bid as low as .01 per click. This means that if an affiliate needs to attract 500 visitors to make a sale, as long as the commission is over $5 he will make money.

What if he only needs to attract 100 visitors to make money? His profits will be 500% higher.

Affiliate Internet programs can work for affiliates, provided that affiliates use the tools at their disposal to effective market their affiliate links.
