ClickBank is being an intermediator between affiliates and product owners where both wanted to make money. Product owners can advertise their products on ClickBank mentioning with the unique features and commission rate. Affiliates select a product based on the authority and commission rate that meets their requirements. Then they start marketing or promoting in their own way.
There are several websites offering money to undergo online surveys, carry out online searches, and write reviews on products. To get the credit, one needs to disclose certain information to them including one's banking details. This is why you should use this route with utmost care. Some of them may even ask you to register with them before working on projects. The most important watch out in such projects is to stay away from websites offering money that appears too good to be true. Be careful while evaluating the reputation of the website as many of them could be a scam. Most sites promote businesses showing copies of cheque payments which may have been given to the middlemen only.
The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
