Click bank is probably the biggest affiliate marketing site in the world. Bloggers and other people who like to make money online use it, and I also find it to be a fun place to make money online. The problem is that click bank doesn't accept everyone. For example, if you want to sell a book, you can't sell it on click bank.

If you live in Bangladesh or Nigeria, you won't be able to join without doing some things. Someone who lives in an accepted area will have to make an account for you.

If not, you should try other affiliate programs like jvzoo, wealthy affiliate, constant contact, media.net, etc.
