Do i have to advertise the products i wanna sale on amazon so that people can see them and buy them?

You will need to find information ebooks dealing with affiliate marketing, such as can be found at http://www.BestChoiceEbooks.com/

What are you selling? Did you do any research to see what the demand is for such items? Is Amazon an appropriate venue for selling such items? Are others selling same/similar items on Amazon? How are their sales doing? And how do your prices, reputation, references, customer service stack up compared to those other sellers? It is not enough to advertise. First, you need something people really need or want. Second, you need a place to sell it where people can find it/buy it easily. Then consider the best way to reach prospective customers. Marketing does not necessarily buying advertising space and utilizing standard advertising techniques. BTW, I hope your English is better in your Amazon listing than it is here. People do not trust, therefore do not buy from, someone with a poor command of English. Poor or sloppy English (or whatever language your market reads/speaks) is considered a sign of poor quality products & sloppy service.
