These are the most important things in home staging:

Curb appeal id the first thing a prospective buyer sees

Depersonalize your home.

Put away clutter.

Place a great smelling glade or air wick plug in by the door.

Make your home appear comfortable, appealing & welcoming

Play some very soft music in the background

Lighting is important also. Open the blinds and put on all your lights so the prospective buyers can see everything.
