Good manners matter a lot. A well-timed "Grüß Gott" or "Servus", being on time for a date and using the formal "Sie" at first all make a good impression; you switch to the informal "du" when the other person suggests it. Austrians also appreciate dry humor, attention to detail and a certain restraint with compliments.
Don't judge their reserve too quickly, as it often hides deep loyalty. To win over Austrian women or Austrian men, rely on consistency, courtesy and concrete plans rather than over-the-top gestures.
