The conversations you have at a conference are typically brief, so it’s key to be clear and concise about what you can do for other people and what you need.
Instead of going right in with a pitch, ask questions about them and what they want and need. Nobody wants to hear your pitch, but people love to talk about themselves and what they’re trying to get out of being there.
Be sure to keep it brief. Think of the K.I.S.S. method (Keep It Simple, Stupid), because everybody is trying to meet lots of people. Make your chat a surgical strike, and leave details for later.
Basically, think of each encounter as an elevator pitch, not in that you are doing a hard sell, but for the time you have. Be brief about yourself, and try to keep them wanting to know more.
Since your opening lines are essentially the headline for your conversation, split test them. No, I am not kidding. Try different approaches and pay attention to what is most effective.
