raincoaster, one of WordPress.com’s most popular bloggers, had this to say about Adsense:
I have had over four million hits on my blog and even though the adsense account connected with it is ALSO running on an external blog, I have yet to make sixty dollars. That’s an average of less than ten dollars a month for hits of 30,000 a month and more. Hosting costs ten bucks a month and up. You do the math.
Rain can run Adsense on her site because she qualifies for the special AdControl program, which is a revenue sharing program that WordPress.com started a couple of years ago for sites with 25,000 or more page views a month. The vast majority of WordPress.com’s approx. 32 million sites do not receive that kind of traffic.
Do you have an external site that runs Adsense? If yes, what kind of profit have you earned from it?
