Affiliate programs are now one of the most popular ways for webmasters with lot of traffic to their sites to earn good money.

There are many factors which influence the amount of money earned by an affiliate. The most important is the quality of the affiliate program. So if you want to make lots of money, you must know how to choose an affiliate program.

First of all you should look for a web site that has been on the net for some time. That's how you know that you can trust them and you will receive the money you make. There are many untrustworthy programs that fooled a lot of webmasters with promises but they never sent the money.

Next step is to check the quality of the products the site is promoting. Don't advertise a product if you wouldn't use it for your self. You shouldn't be blinded by the high commissions an affiliate program is offering. If you join a program with bad products you will damage your image and you won't be able to advertise other products ever because people won't value your opinion.

Try to find an affiliate program with a good commission rate because you don't want to waste your time if you can make much more money elsewhere. A good commission would be a 20% to 25% of the product price.

We have discussed about the web site, the products and the commissions but none of this matter if the program doesn't have a great tracking system. You should look for programs that track visitors to their site using both CGI and cookies so you'll get your money for the sales you make.

It's also good if you can check your stats in real time. Before you sign up in a affiliate program you should first check how long do they track visitors for. There are affiliate programs that track a visitor only once and if they come back another day and buy the product you won't earn ay money. So best for you is to find programs that track visitors for 30 days or more.

Then you should be interested on how often the site sends your payment and if you have to earn a fix amount of money before they send them to you.

So these are some tips in choosing an affiliate program that will bring you a high income. If a program has most of the things mentioned above then it's worth trying.
