One of the most effective ways of promoting your content is to turn it into an event. Build up anticipation for it among your audience over time, so that it sticks in their mind, and make its ultimate release something they won’t want to miss.
So the question remains, how do you build up anticipation for your content? With more content, of course! One particularly effective form of content is the teaser. Movies have been doing this for years. A brief scene or a collection of footage, generally ambiguous or out of context, serves as an introduction to the film, and leaves audiences wondering what it means and wanting to know more. Which in turn encourages more people to see the film.
