When your opponent c-bets, it's always good to look at the board and your current hand's equity. If it's a "wet" board with lots of flush and straight draws, and you have suited connectors that could make the nuts then I would call or raise these c bets. If it's a dry board and you have second or third pair and the opponent c bets and keeps on increasing the bet size, it makes sense to fold your hand because it isn't improving and you're basically bleeding chips by calling.
I don't mind calling c-bets when I have a draw-heavy hand. I will fold hands if they don't improve by the turn or raise as a bluff.
