My suggestion is to not look for the high paying keywords for a main site. Create something that you have a little passion about. Build up your member base, build up your content, build up your reputation, keep on building and then you will be granted

Yes create a few pager websites that gear towards high paying key words but I would rather enjoy a nice open layout that people will come back time after time instead of a one click they are gone and never see them again
My vioxx sites I use to have were like that... but again I was in the market for them to get help I couldn't help them... also that was paying upto $15-$20 per click. I am still glad to see that site still active at a parking company
GOOD LUCK
