I don't think it's possible to advertise your poker site using Google AdWords. Maybe you should try SEO instead. But it will take some time.
I just want to say I LOVE your country! It seems it's the only country who believe in freedom and not controlling the people and allowing them to make their own choices.
Not in the U.S. via Adwords. Not sure about elsewhere. You might want to keep your gambling related site away from the U.S. altogether. I know Kentucky is seizing sites that advertise to people in their state. I used to have several portals and sold them all as affiliate advertisers can be put in jail if they decide to charge you with unauthorized promotion of gambling. Land of the free eh?
I know RevenuePilot was full with casino and wagering ads so why it will be not allowed to promote casino !!
Yeah I don't think that Google allows this in Adwords. Doing the SEO yourself will be difficult too it's extremely competitive. Good luck
