Hi Gamer, I see you haven’t got any response yet. Although I’m also new (1 week) to the indusrty I’ll see if I can help you out. (been an affiliate for almost everything else out there)
I’ll avoid giving you advice on what type of gambling site you should develop since I’m still working on my first one, but being the PPC maniac I am, I can give you my first thoughts.
I’ve being trying Adwords this week, and it doesn’t really look good. These google guys can really drive you nuts. If you do search for “casino” or any related term, you’ll see at least half of the ads breaking the adword rules, while the rest are borderline. I tried to get some ads up there but the got stoped within hours.
My guess is that people are going for the good ‘ole bait and switch. The other strategy seems to make a landing page where you get peoples email addy and then send them some free “make a ton of money” ebook with your casino links on it to get them to sign up.
Other than Adwords and Overture I wouldn’t bother with any other PPC they’ll just take our money and send crappy traffic.
