Lookt your target audience and look at what you are offering.
If you take a vegitarian to your favorite steak resturante they are going to be pretty p!ssed with you as there is nothing on the menu for them, if however you take them to somewhere with more variety that is suitable for vegitarians and also sells steak you are on to a winner.
Second base!
Looking at some of the casinos you offer they dont accept vegitarians…well US players. 60% of your traffic is US – there’s a problem.
Also try offer more content to the players rather than just banners, more indepth reviews are required to help make the player make the best choice for them, tell them which are the casinos that take US players and vegitarians to save them looking.
Hope this helps a little?
