Hooking your audience into being interested in your content has to occur right off the top as well as throughout your delivery. There are a ton of shiny things around and we get distracted easily.
Teasing provocatively about the content to come still works well – it keeps you from blowing the attention you have and losing me before the main event.
But a tease without a bit of a payoff is cruel, and I don’t pay attention to cruel people.
I don’t care unless your tease makes me want to care. Give me something, hint, tempt, provoke but leave the best part out.
If the tease is tantalizing enough, I can still get a sense of fulfilment from the content without having to sit through a couple of songs or a commercial. A good tease can be all you need.
