I was discussing one of my colleague about an issue. While talking he told me that we should choose such keywords which have High Competition and Low Traffic Volume. I was amazed on his theory. I was searching high traffic and low competition keywords from the beginning of my career. So, I asked him why should we do such thing but he did not replied me directly. I think that there should be some myth inside this theory. Should we really choose such High Traffic and Low Volume keywords or Not? Needs your Opinion.
