How to earn money online from ClickBank ?

ClickBank lets the you earn a part of the revenue you make for their customers by facilitating sale of their products. ClickBank provides you a customized referral link which you can use anywhere and if a sale takes place with a customer arriving from that link, you get a handsome commission(which sometimes is more than 50% as well). All you need to do is get some eyeballs of targetted people who might be interested in that product and direct them through your customized link for that product (also called affiliate link). Following are some of the ways people achieve it:

1. Write a good review of the product and then put a "Click here to buy" link at the end.
2. Put some links for products based on the context of the article.
3. Spread the link through social networks like facebook, twitter, etc.
4. Identify the traffic you get on your website/blog and then analyze what product they would be needing and accordingly put a product link on the sidebar or something in your website/blog.

Though it is all good till now, there happens to be a way to get some of the clickbank products without even paying using simple Google search queries like:

1. <product name> inurl:”?cbreceipt=”
2. inurl:”?cbreceipt=” site:www.<productSite>.com
3. Thank You For Your Order + download site:www.<productSite>.com
4. Congratulations site:www.<productSite>.com
5. "Your Credit Card Will Show A Charge From"  site:www.<productSite>.com

The result page will have the download link for the product and then it can be downloaded for free. The above is possible only if the product site hasn't been configured properly to not include the page having the download link in search results (This can be done by telling search engines not to crawl them by configuring the robots.txt file). So if you happen to be on the other side, just take care of these things when you put your product up in clickbank.
