I just wrote an article on this last night. Getting traffic is one thing, but getting them to convert, that is the key to success!
I firmly believe that the best way to convert players is to provide a perception of value. If a player feels they are getting something more from you than another affiliate or directly through an operator, you are giving them the best possible reason for them to click on your links and take action. Whether it is value added private tournaments, up to the minute news, strategy, a better deposit bonus, etc., I feel that the best means of conversion is by offering value to the player.
