1. Show respect for the other person's opinions, especially when

they contradict yours. People at conferences are experts in their field and they probably have strong opinions on a lot of subjects. Whenever you find yourself discussing a controversial topic, be gentle. Never say "You're
wrong." Listen carefully and respectfully. You might even find people
who have feedback on your product/service and are brave enough to deliver it to your face. Listen to their pain points. And…
2. …If you're wrong, admit it quickly and emphatically. Thank the person for the feedback. Take notes. Take the required actions when you get back at the office.
3. Begin in a friendly way. (See point 2 in How to Make People Like You) Listen. People who go to events to network are usually extroverted and talkative. They are not afraid to talk about their business in detail. It's better to walk away from a conversation when you've let the other person speak more than you did.
4. Start with questions to which the other person will answer yes. Do you want more leads? Do you want better performance? Do you
want more traffic? Make them an offer they won't be able to refuse.
5. Let the other person feel the idea is his or hers.
6. Try honestly to see things from the other person's point of view. Ask constructive questions and give your partner the feeling that you understand them and their business.
7. Appeal to the nobler motives. You are the event to find people in distress and offer them help. You are a problem-solver. Be there for them.
8. Dramatize your ideas. Be a storyteller and put into perspective your ideas for your audience. Emphasize the impact your product/service has on your current and past customers. Throw in some names when appropriate.
9. Throw down a challenge.
10. Be confident. Ooze confidence: others will feel it and gravitate towards you. In group conversations, contribute to the topic early. Again, have a clear idea why you are at the event and what do you want to achieve. Have a friendly smile and approach people with determination.
