Before you go to your next conference, take this advice.
Here are some great trade show tips from Gaspedal. I really liked these three:
6> Speakers: How to turn the audience into customers: If you don't have a handout, you've wasted your time. You spent all this time and money to speak, then you give people no way to buy from you. Always print a 1-page flyer, staple it to a printout of your slides, and put it on every single chair before you start. It's a guaranteed way to get new business.
9> Travel light: Leave the briefcase behind. Take no paper from vendors. Just bring a nice suit and business cards. You're here to meet people and have conversations. You don't need any stuff. Spare your back, lighten your load. You'll be in a better mood and you'll be more effective.
15> Skip the Sessions, Work the Halls: If you're looking for customers then never go to a presentation. You can't network in a dark room during a speech.
