I have currently 166 domains, and I actively work on a dozen of them.
I usually you direct them to my active domains, however, that offer a confusing user experience and questionable return.
So I was looking for some alternatives, unused domain names in my portfolio money, many quality.
Hosted domains in Google AdSense and some other solutions I've tried with modest results, but I think that I've found a winner with TheParkingPlace.com.
According to TheParkingPlace.com, you can generate up to seven times more revenue than traditional PPC methods with them.
They said that they surpass result in domains with high traffic and low RPM (rate per thousand uniques).
You can see an example of a user-defined page from TheParkingPlace.com to GasPrices.com.
In any case, I will give them a try and see how it goes.
