This is a discussion on Online Tells within the online poker forums, in the Online Poker section; What types of tells can you pick up playing online? When you cant see the other person it seems tough to do.
They are not 100% reliable but they are usually based on timing or bet amount.
One well known one is letting the clock and reserve time count all the way down to near zero to make it appear they are having to make a tough decision and its the nuts more often than not.
Like ChickenArise said it's about betting patterns. There players that min bet when they have little or no hand. One reraise and they fold their hand. While other players might min bet with the nuts. Learning a players betting patterns is a key to online poker.
Doesnt this depend on the player? I'm not sure there's exact set of tells that fits most players. It comes to mainly betting patterns/bet sizes I'd say. And to avoid givng tells through bet sizes yourself, your bet sizes should differ from person to person depending on their play style.
Betting patterns are one of the best ways to read a player. Also take into consideration of what stake, table size and player volume are being played. Other factors such as playing a cash-game or tourney may also have an affect on players' tells like betting 3-5 times the BB which usually indicates a big pair, depending on their relative stack size, as apposed to someone shoving which usually indicates AK-A9 or a small pair. It's when players mix this up that you've got to watch them closely. A nice 3 bet or check-raise can usually give you a better read, as well. Good luck.
Playing online actually will improve your live tell making ...well in most cases. Because you're focused more on betting language then you do body language.
Usually how they streamline their bets is how I can tell if I'm ahead or behind. If they are jamming on the flop (outside of a freeroll) they are behind almost always. Usually the ones who are trying to trap always throw out some min bet to build the pot , those people I love because I catch up a lot of the time.
There are specific tells for the online poker. Size of bets along the streets; player timing; betting/calling/folding from determined position..., despite they are imperfect informations, they still are good start point so.
Best of Luck

I distinguish 3 groups of tells.
1)the behavior in the chat people talking about the game, insulting others, complaining of bad luck it is possible to determine the degree of tilt.
2)the time for making decisions. If a person made a decision quickly, and then took a pause - maybe he is thinking about value-bet or preparing a bluff. Here you need to follow his style of play - maybe he plays on several tables
3) all the other tells - he puts a big blind without waiting for the queue - beginners and fish; does the moves automatically: call BB, check fold, automatic raise - plays on several tables, often goes to the sit-out - the game is not particularly interested in.
