A good betting site or sportsbook offers good odds, numerous sports events to bet on and good bonuses. But that is just a start. You want your money to be safe, that is why you want to play on a SSL-Encrypted sports betting site.
You also want to make sure the sportsbook you play on is licensed and that they offer payment methods available to you. Last but not least, you want a betting site to offer a great experience on any device.
