How to sell your soap?

My friend Mindy (Fang, Minzhi) posted this educative video on her blog, which I find it quite interesting to comment about it. The video, how to sell your soap, shows different possible marketing strategies of selling a commodity: soap. It starts with an old-fashioned way: walking around and ringing doorbells and sell your products door to door. It is time-consuming since the more you want to increase your sales, the more you have to walk. Alternatively, you could build several billboards in the shopping malls or broadcast your soap ad through TV, hoping people to pay attention to your soap promotion. Although this kind of promotion method gives you a key access to your audience, you do not know which group of people is your main demographic. How about building a strong brand image and letting your loyal consumers tell their peers or family? Some people may think that friends’ words are more convincing than what TV ads say. That’s what viral marketing means!
