Be Calm and Confident.
The more nervous you are, the more prone you are to stutter and make mistakes when talking. You'll also have a very tough time coming up with anything interesting to say when you're anxious. So take it easy and be yourself. Women may notice if you're just "acting" out to impress her, and this might even turn her off.
Ask The "Right" Questions.
Ask questions that will encourage her to talk further and flaunt her ability or experiences. Don't ask questions that lead to a dead-end answer such as "yes" or "no", or questions that delve deeply into her private life (especially when you've just met). Moreover, don't ask silly questions for the sake of having something to say.
