if i raise and get one caller, if i hit i will bet, and if i miss i will conti bet and try to take the pot down on the flop. If there are more than one opponent and i miss if i am in position and they all check i will conti bet if i feel they will fold, if not i will check behind. If opponent donk bets before me on the flop and i miss i will fold, but if they keep doing this then take note of this, they could be bluffing then you could consider raising their pot bet.
If like you say you miss the flop and there are multiple fish without any strong draws i would just check/fold this as if you conti bet against the fish you will just get called and then you are in a tight spot on the turn, double barrell or just c/f? If you have a strong draw eg flush draw or oesd or both, then its worth a bet because you will build the pot up and then if you hit, especially with multiple fish, you will often get paid off big.
I built a pot up the other day got flush on the turn, a 4th diamond came on the river and i pushed the rest of my stack ($5 into a $9 pot i think or something like that, he called and shown AK clubs, he hit a pair of kings on the river, and called a push even with 4 diamonds out, so often you will get paid off by these fish
Hope this helps
