Statbrain

Statbrain is an interesting application that lets you track the number of daily visitors of any site simply by starting its url. Statbrain provides an assessment by combining the mathematical and statistical data obtained from different sources and with its own method of calculating the hypothetical received visits from the site in question. The service is functional and free, and although it provides the numbers with a margin of error plus or minus big (anyone can do a test with the statistics of your site to get an idea), remains a useful tool to Statbrain know the traffic of others.
