Statbrain is a online web stats tools that helps you guess the number of page views on any site using a combination of Alexa rank, backlink counts from Google, Yahoo and some other unknown factors.
Don’t expect it to be too accurate, but if you want a very rough estimate for any site, this could be useful.
This could be very handy for advertisers or people who are interested in measuring rough traffic on a competitor’s website.
You may also want to checkout Google Trends as they are pretty accurate.
StatBrain gives an estimate about number of visits and not unique visitors or page views.
