I think that was one of the worst pieces of advice I have ever seen you give someone Prop
Pros - Can rank better but not always
targetted traffic
higher
conversions in most cases but not always
Cons - hardly anyone will link to you - why because the site itself doesnt provide value
Means you will need to buy links in most cases
Poker rooms can change their mind in a split second - if they do they could also refuse to pay you
Putting all your eggs in one basket
If you are thinking of doing it you should ask first - always ask
and for the sake of writing it the majority of the xxxxpokerroom domains are taken...you will probably be left with something which needs you to have 2 - 3 hypens and will not do as well as others or a .net, .info etc which has to compete with the .com..just my thoughts
edit - not saying there is anything wrong with it but depending on how you do it it can be a plus or a negative....just check with the rooms, keep that email for your records
