While walking around an expo last week, I saw exhibitors talking on cell phones, chatting with co-workers, eating, and worse: leaving their exhibit area unattended! I wondered why they were even there because they were putting barriers between themselves and their potential customers. Expos give a company a very targeted, but small window to reach potential customers. A skilled presenter in a booth will attract masses, pre-qualify them and send them right to the sales staff. Make sure you have some of your best sales professionals manning your booth at any expo you exhibit at.  Time is money!
