KNOW YOUR COMPETITION!
Whatever business you are in, you should know as much about your competition as possible, I think there is no need to argue about this. You should know what your competitors sell, where they sell it, how they get customers etc … Online business is no different – whether you are running an e-shop, selling someone else’s products or simply promoting something as an affiliate, you should always know who you are competing with, in order to get as much visitors as possible to see your and not your competitors advertising campaigns.
