In my earlier article I posted how to earn money through internet marketing. This article is about how to promote your products. Actually the best way to increase the demand of a product is by internet traffic. Eg: if you have a website or a blog and you are a registered member of a clickbank.com (flipkart.com,amazon.com ,sfi.com etc are some other sites) you are wishing to promote one of there product. Firstly you have to write something about that product in your blog or website then add your refferal link to buy that product. If your website or blog has a good page rank or great traffic then you will earn quickly by the sale of the product. But if your website or blog can't have much traffic then it will be tough.
You can increase your blog or website traffic by adding your website to the PTC website , advertisement offering websites at first sometimes you need to spend some cash for this. You can also use free classified sites like olx.in, naukri.com etc for promoting products, these sites have very good traffic and one can post there classified in there free. As a source of getting more customers the most important thing that you need is this online traffic. Imagine if your product has sale price 50$ and if you sell it your commission is 15$. You are trying to promote this product with classified websites and through your blog or website and you got 500 views and from that 10 person were interested to buy your product. If they buy you will get 15$*10=150$ with single product. Just like this one can turn there blog or website into a internet shop where you will earn profit. So online traffic has a big role in the promotion of a product and your online earnings.
