They don't follow up!

Here is where you can make or break your trade show experience- the entire point of having a booth at trade show is to get leads, and you must follow up with those leads after the show. Your job does not end when the show closes down, it's only beginning. You must follow up with your leads within 10 days of the show, the sooner the better. It can be an email, letter, or phone call, although it's always best to have voice to voice contact with your perspective contacts. Remember don't waste you time with the people who were not interested- you have already weeded out the time wasters- so you should only be calling interested parties!

Remember people will not call you, they most likely do not even remember you, they met tons of people at the show- you have to follow up with them and remind them that they need your products!
