Public speaking is a good way to position yourself as an authority in your industry and to help raise the audience's awareness of your product and concrete in general. The time it takes to speak to groups pays off in future sales. It is also a good opportunity to distribute company and product literature. Keep in mind a few simple guidelines when speaking: keep references to your product subtle; know your subject well; bring materials which will help your audience understand your topic; target your ideal audience; and ensure press coverage.
