Making money from parked domains?

So I have five domains in which were meant to be used for domain parking.

I actually got the names from the guy whom I was working with as a JV for the parked domains. We planned on using Voodoo and he had some traffic source plan but I sorta cut off connections... Don't remember why, it a year ago though.


Anyways, is there anything I can look at to help increase revenue from these parked domains? I have seen others around this forum claiming to make good sums of $$ with parked domains but I am clueless where to start.

Any help is really appreciated.

The 5 domains were researched based on the keywords of the domain to maximize $ per click.

Lookup "sedo" -- this is one of the more popular services that pays you to park domains with them. Of course, they take a cut of the revenues.
