The best dhv of all time is social proof. My favorite technique to create social proof on the spot are using "pawns". I open up a set of a couple women who I'm not exactly interested in. After a few minutes, I suggest to them that we go meet some new people. I then lead them over to a new set and open it. The first set is basically a dummy set in order to open the real set with ease and create social proof. This is a great way to DHV without saying a word.
What are some of your favorite DHV tactics?
