When you think about how to excite your buyer, it's helpful to take two different categories into account:
1. What buying stage they are in:
Are they just starting the hunt for a solution to their problem? Are they at the point where they've exhausted their search and are ready to buy? Think about providing information for all the phases they'll go through. Talk to your customers about how and what made them decide to buy. Listen carefully to the words they use and the ideas that captured their imagination.
2. What learning style they prefer:
When you provide information on all your different channels, make sure you take into account the different ways that people learn. They are:
Visual: use videos and graphical information
Auditory: use podcasts, audio greeting, audio testimonials, etc.
Tactile (also called Kinesthetic): use demos, interactive quizzes, step by step how-tos.
A good mix of these will significantly boost your customer's interest in investigating and buying your product. Also, it's key that you don't rely on the style you prefer!
