No its not. As you heard, they make at top .60 cents per month per domain name.
How many do you have? 1,000 ? You will have to develop and host all 1,000 which would *make you $1,000 a month, if they have traffic. Natural traffic that is. Like
You will need at least 1000 unique visitors per month per domain to get a click. The click through rate is about 1 in 1,000.
Sure you can do better. Like 1 click per 300 visitors. But at that rate, you will need alot of hosting power etc.,
Don't waste your time building onto some names which does not have "traffic".
You wonder why a lot of people are buying traffic names for high amount? because they can build sites, sell domains base on the traffic, organic. Don't waste your time and money building.
If you have traffic names, just park them.
Don't waste your money trying to make a living from adsense, in reality for every 1,000 visitors you might get 1 click. So in order to get $100 you need 100,000 visitors unique. Not even namepros get 60,000 unique per month. (at times maybe, but not now)
