In my case, "poker for free" I get a lot of players signing up for some kind of free poker cash, but I educate them
- how to become a real money player,
- how to make the most out of it when depositing,
- etc.
Through newsletters I try to keep them motivated and interested in other rooms.
The value in this players is initially very low, that's correct, but after a while even these players might turn into depositors.
I can say that now about 10% convert into RMP's and even a few that make significant deposits.
Then again, I saw a $200 Added being cancelled yesterday because only 13 players registered.
Cheers,
Giorgio
