You shouldnt be bluffing unless you think it is +EV.
If the pot is $100 and you think a $50 bet will work 60% of the time then that is +EV.
60% of the time steal $100
40$ of the time lose $50
EV = 0.6*100 - 0.4*50 = +40$
Semibluffs are even more +EV in certain circumstances. If you have a 10% chance to win the hand as well if you are called then
60% of the time steal $100
40$ of the time you get called:
90% of this, you lose $50
10% of this you win $100 + $50 = $150
EV = 0.6*100 - 0.4*0.9*50 + 0.4*0.1*150 = +$48
If a bluff has negative EV then you shouldnt do it. It is also possible for a bluff to be break even by itself, but degrade your table image to create more EV on later monsters.
Edit: The only guideline is that the bluff has to work often enough for the pot odds to justify it. So a pot sized bet has to work over half the time. A half pot bet needs to work more than 1/3 of the time etc...
If you bet 1/2 the pot with nothing and your opponent folds 1/3 of the time its neutral EV.
For example, pot $100 you bet $50
2 times you loose $50
1 time you win $100
100- (50x2)=0
If he folds more often its +EV, less often -EV.
The better you are a calculating fold equity the better you will be at making these judgements.
