What type of blogs do you have and how much can you make in bitcoin? Are they bitcoin related ones or can they be about anything?
Hmm... they are all porn blogs.
I put them up in 2008, without much effort. Then I updated them like once every month or so. I am earning good amounts of money from them. I am earning around BTC0.1 for every 100,000 page-views. That is around $23 for every 100,000 page-views, or $0.23 for every 1,000 page-views. Quite good revenue for porn blogs, if you ask me.
Couldnt you turn it into autoblogs? I guess you dont produce the content yourself and your blogs are anonymous. So since you take the content from somewhere, wouldnt it make sense to automate?
