It's been my observation that the majority of "bouncing after touchdown" landings (mine included) are the result of trying to touchdown too soon. This generally means that the nose gear touches the runway first. And if it does, you're just about gauranteed to go bouncing down the runway (or off the runway...)

For myself, once I'm in the flare and about 1' off the runway, I just hold it there keeping an eye on the nose gear. Once I'm sure that the nose gear is higher than the mains, I'll let it settle onto the runway. The next bit can also help. Once on the runway, I don't just let go of the elevator. I keep holding it until I'm sure that the jet is stuck to the runway. Then I relax the elevator and commence braking. You never know when a small crack or something else will cause the jet to lift off again after touchdown.
