There are some indicators in the game of poker in which you have to be capable of making profit of them. In the lobby of online poker rooms you will find the following indicators: when the average percentage of poker online players who see the flop is high, the game is normally favorable. The percentage must be of at least 35%. When it is like that - you will have a lot of probabilities of gaining money.
When the average size of the poker pot (average pot size) is big, obviously you will have more opportunities to gain big pots. The ideal thing is that the size of the average pot is of at least approximately 12 times the big blind. When this happens, it means that the game is loose and this is exactly what you want to gain money.
Remember that the structure of the online poker games changes rapidly. The players change table all the time and what turned out to be a good table can turn into a terrible table in a few minutes. You always have to pay attention to the type of poker players whom you face.
When you play in live poker games, there is no lobby that provides the statistics that you need. In this case, you have to observe yourself the game and then decide if you want to play or not. This type of evaluation of the game is more difficult and it needs obviously more time than in the games online.
