Wikipedia defines an elevator pitch is a short summary used to quickly and simply define a product, service, or organization and its value proposition. The name "elevator pitch" reflects the idea that it should be possible to deliver the summary in the time span of an elevator ride, or approximately thirty seconds to two minutes.
The key to any elevator speech is to have a short, defined, to the point speech that entices people to ask a follow-up question, thus starting a conversation. Consider it the ice-break before the sales pitch.
When asked what you do – do not say I am a clown; instead . . . I'm a specialist in fun, who helps parents control kids at birthday parties, while making it memorable for the guests.
Use words like specialist, fun, exciting, control, words that have action and are descriptive. The more interesting you can make the elevator speech the better your response when presenting it to a customer. How often are you asked while performing what is your day job?
Avoid using jargon, technical terms, or fancy acronyms that nobody but you understand. Keep it fun, interesting and easy to remember. You want this information to roll off your tongue smoothly and gracefully. So practice, redefine, and practice some more until you have a speech that defines what you do in a creative message.
