There are some types of landings, can you, please, clarify them? Or even add some other types
From European Action Plan for the Prevention of Runway Excursions 1.0, Appendix E- Aircraft Operators:

Deep landing – a certain distance behind the glide slope touchdown point
Short landing – touching down before the glide slope touchdown point

Belly landing (or pancake landing or gear-up landing)-  The aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device.

Partial gear up landing- One/or more of the landing gears fail to extend. Similar to belly landing, but in that case, all the gears fail usually.
Hard Landing- The aircraft impacts the ground with a greater vertical speed and force than in a normal landing. The actual speed varies from aircraft to aircraft. This kind of landing usually requires some inspection afterwards.
Nose pointed down landing- Aircraft usually land at a positive attitude (i.e. with nose pointed up). However, in some cases (usually due to some problem), the landing can be carried out with nose pointed down. This is normally in violation of standard procedures.
Arrested landing- Usually done in carriers; an arrester cable is used to bring the aircraft to stop.

Smooth landing- If the landing has no problems like given above, it can be called a smooth landing. It is subjective though.
