There are a lot of scams on the World Wide Web. There are a lot of programs and tools that are worth paying to access. Many tools have affiliate programs that pay referral commissions. You sign up to promote a service or tool and get a link code. You can send that code via email or post in places that have traffic. If a person clicks on your affiliate link and buys something, you should get paid a referral commission or referral fee for that effort.
Some systems don’t pay their affiliates
You may find yourself in a system that doesn’t pay you. Your balance may be growing, but the owners of the program have designed the program to not pay everyone or make it very difficult to get paid. Seek out other affiliates and find out what they have experienced before you waste too much time with something new. I have had some success with several affiliate programs. I have also seen my share of scams that have wasted my time and efforts..
