What are good and bad flops to make a continuation bet on?

Say you raise from 3rd position and get called by CO. You totally miss the flop. The money is fairly deep. What are good and bad flops to make a continutation bet on?

I would say that disconnected low flops are good, as villain probably didn't connect, and you can represent an overpair. If an ace hits, you can represent that. Multiple high cards like KQx may have hit your opponent, but if he didn't connect, it is easy to get a fold.

Something like QJ9 with a 2-flush is likely to hit your opponent. Plus it is harder to represent you hit with a standard raising hand. A paired board with a reasonably high pair probably didn't hit your opponent, but he may figure it missed you and play back, representing trips.
