I just started my blog last week. This is a sports blog and I add Adsense on my blog same day. Look: http://www.sportscentre-rohit.blogspot.com/ And i am very happy to see $8 bucks in first week from my site. I dont know much about html or any seo tips. Just earning comming from DP and may be some other visitor. I think this is good start. What do you think?
In about 15 days I'm using Adsense since one year, and i'm earning $5/week .. but atm i've got just one website, that will be the reason.
