Earning a dollar a day just shows you that it's possible to earn with adsense. You can build that up with some work and focus...easily
I was beginning to think that adsense was dead before reading this. I wonder what those guys real secrets are.
I read an article about Markus Frind (PlentyOfFish.com). http://www.readwriteweb.com/archives/plentyoffish_one_billion.php (2007). He said he'd cross the $10 Million mark in 2008 (30k/day). Not bad for a two person company eh? In terms of traffic, currently POF gets 1.2 billion page views/month, and 500,000 average unique logins per day. Markus says that per page view, Plentyoffish has 5-10 times the click through rate of Facebook. Another article (wall street journal) http://online.wsj.com/article/SB117987775136211487.html As an aside, apparently the guy has a math paper that was quoted in a nobel prize winner's stuff. So I think he's more than lucky.
That is huge earning. the most important is the owner does have more sites like that. the earning is huge!!!!
they are great and smart people..unfortunately i've just made $5/day from adsense..but it's increasing day by the day...I have to work hard to be same as them..
I know people with more than 150k / month and don't see them in your top. I don't believe that 300k is the top of adsense revenue.
