Call to action keywords could maybe work, play around with "win jada jada", "make easy money", "free something" stuff. I tend to go with the make money keywords and I usually get a few curious clicks here and there. I am sure other people here have more experience with finding good keywords.
Got them with traffic? If so, host them for some days (use a php bulk cpanel creation account) and check their stats to get an idea of the keywords. You can also use domain dashboard to make things easier. Then move to park.
