This is one of the top niches of affiliate marketing. Conversion on your casino websites with major SE’s traffic all comes down to casinos accepting US players. There are only few casinos left which dont have big problems with billing players from USA.

Out of all I use the best result showed this one, in average each depositor brought me 1184$ which was 20% higher than 2nd casino I use (link) and substantially (over 50%) higher than 3rd one. Overall it took me several months to filter bad casinos out and huge money in unrealized revenue before I settled on those 3. Always keep in mind they are best for US traffic but might fail short on traffic from other countries (80%+ of my gambling traffic come from US according to logs, if your traffic comes from Google mostly you will see similar numbers).

My next post will be about quality of keywords and how to not get into adwords “traps” promoting site for “popular” keywords which actually dont have any traffic. Such as “casino gambling” for instance.
