What is Alexa Rank?

 Alexa Rank:-

The Alexa rank is a ranking system calculated using the Alexa toolbar. Alexa takes the browsing data from the millions of people using this toolbar and calculates the traffic ranking of each site based on reach and page views. Low traffic sites are harder to gauge accurately, but once a site reaches a 100,000 or less ranking the accuracy of the measure increases. Hence the lower your Alexa rank, the credibility of that ranking is increased. Whether you value your Alexa traffic ranking or not, there are definite advantages to having a high Alexa rank. The Alexa ranking is viewed as a reasonable representation of a site’s traffic and authority.
