With all that goes into an experiential event, letting guests leave without any way of hearing from them again is a waste. A simple mobile sign-up can link visitors to your campaign or website with no badge and little fuss, as long as there is a real reason to take part.
Consumers can share basic information with a phone in seconds. An automatic reply by email or text then gives you the chance to prompt the next step: register, enter, vote or visit. The creative possibilities are wide, though the legal ones are narrower, especially if a prize is involved.
The classic formats are still around for good reason: fans entering a live draw for a seat upgrade at the stadium, or shoppers entering to win a car at a launch. Invent your own, then measure what people do afterwards rather than how many of them entered.
Smart posters are cheap and easy to overdo. Where tags and codes earn their keep at events, and how to avoid dead ends.
A prize draw remains the fastest way to collect names at a road show. How to run one that is lawful, fair and useful afterwards.
