We can grow our business online by different methods, I personally used this method and get good response. I started earning from affiliate marketing and for this I designed a website about health and fitness then I placed my products link in that website after this the main thing was left as how to get traffic in my website, the best source for traffic I found Quora.com so first I made my reputation over there by writing quality answers which started publishing there on regular basis and when I felt that now I can place my website link there then I started placing my health and fitness website link there so when people were reading my answers they also click on the link and sso the chances of selling of my product increased too much.
