Hello webmasters, There is a huge difference in the ranking of Alexa and Similar web. On which factor they decide the ranking ? Which ranking is real, Alexa or Similar web ?
Alexa, Compete, or this Similar web are just rough indicators of traffic. They have limited ways of gauging it, like from a toolbar or other tracking code, which most people don't use. So, unless your site is in the tens of thousands to millions of visits per month, these will be highly inaccurate. Google analytics tells you accurate visitor stats. But these only indicate. Compete, for example, underreports all stats around 50% of actual.
Each used different metrics and calculations. Only they know how their formula works. You will not get the same results from any 2 tools you use.
