Be assertive not aggressive. Be professional at all times. The more people you attract to your booth the more successful it will be. If a prospect has good eye contact with the representative, it means he or she is interested. The more serious the prospect's intention, the more likely he or she is willing to wait for a salesperson.
People visit a trade show to learn only what is new.
Good sales techniques that work in the field apply equally to the exhibit selling environment. Too many people in a booth reduces the quality of interaction with each prospect. Extended eye contact shows disinterest and passive thought process. Today's customers are smarter and better informed. Show selling is different.
