• Use the right hand, full grip with fingers under the palm (not the fingertips!) 
• The hand should be midway between the both of you.
• Shake with a firm squeeze: not too hard, not too soft. 
• The optimal number of shakes: three, with medium vigor. 
• A hand shake should not last more than 2-3 seconds. 
• Maintain eye contact throughout. 
• Pair handshake with an appropriate verbal statement ("nice to meet you," versus "did you just come from a seafood restaurant, because that hand sure is clammy!")

And there you have it!
