Too often experts will dive into their presentation without presenting a roadmap and this usually leaves the audience unsure about what is going to be covered, why and when the presentation will end. Presenting a table of contents before they dive in and begin to talk puts everything into context and helps your audience to know where they are in the presentation. Road mapping allows the audience to see the key points you are going to explore and puts them into context and helps them relax into your teaching and allows them to relate it to the bigger picture and the promise of your presentation. I think if you implement this simple framework with your content, copywriting and speaking you will begin to see a sense of trust, and ultimately this will lead to more conversions.
