Adult Studios Top 75 Traffic Report
If you go read their disclaimer they say not to follow anything thing ranked 100,000 or more.
Disclaimer:In addition to the biases above, the Alexa user base is only a sample of the Internet population, and sites with relatively low traffic will not be accurately ranked by Alexa due to the statistical limitations of the sample. Alexa's data come from a large sample of several million Alexa Toolbar users; however, this is not large enough to accurately determine the rankings of sites with fewer than roughly 1,000 total monthly visitors. Generally, Traffic Rankings of 100,000+ should be regarded as not reliable because the amount of data we receive is not statistically significant. Conversely, the more traffic a site receives (the closer it gets to the number 1 position), the more reliable its Traffic Ranking becomes.
Your friends site is at 3 million because:
a) His site is for mac users only(alexa stats are IE browsers only)
b) he has been banned from a major search engine.
Mc) he has all secure pages
d) email spamming.
e) he is a friend of yours.
alexa will soon be sold to google or amazon and google partner together and use alexa's technology Then it will be 100% correct. I look into the future and what tools will be used from that. If tomorrow there is a gift from God and gives us a site that is right on the money, Then I'll list adult industry site from there.
