Have a room with excellent software and maybe advertise it heavily on TV at first, with some familiar poker pros.
Rake between 5-10%. Keep the rake for the micros at 5%. Have it increase to 10% for Low stakes, 8% for mid, 5% for High & 2% for super hi roller.
Bring back Nose Bleed stakes cash games.
Bring back player chat and observer chat and have some sort of special promos running to help build up activity there.
Have some of the sites 'Pros' run a
bankroll challenge, starting from ZERO and building to $10k & invite all players on the site a $100k Prize for 1st (for whoever makes it to 10k first). Repeat a similar contest each year, starting from the beginning of the year.
Create a rewards program that puts some type of accolade on your avatar. Call it maybe 'Star' and 'SuperStar'. Carry those rewards over into the next year for those who were able to qualify for it in the year prior.
Any sponsored pros must actually play on the site. In Sunday tournaments, any pros you happen to KO on your table will be rewarded with a T-shirt sent to your home address.
All players must play with webcam activated. This is for random spot checks by the site's security team, making sure it is really YOU who is playing at your computer.
