Elsha, Google analytics is indeed awesome tool! but I would like to say that I need to estimate the traffic of 3rd party websites i.e. Websites which I don't own, it could be competitors websites also! So in that case I can't get access to my competitors Websmater tools account right! So is there any tool for carrying out this process?
