The mistake most book trailer creators make is making the trailer far too long.
Many trailers are two minutes, sometimes up to four minutes long. At this length the trailer suffers under is own weight and become full of padding, which where the creator is simply tring to pack any and evey idea they have into the trailer.
The work of an amateur.
Consequently at this length the message of the trailer loses its punch and the impact is lost.
The book fails to serve its purpose as being a tool to create excitement, anticipation and curiosity for the viewer.
These three components of a book trailer is what moves people to buy the book, or st least prompt the viewer to check out a website.
So how long should the trailer be?
The ideal length of the most effective trailers are between 45 seconds and 1 minute, 10 seconds.
It’s a sweet spot, where the trailer creator is forced to keep only the most critical elements required to successfully communicate the books tone and message.
It’s why those 30 second movie teaser trailers work so well, creating anticipation for the viewer who’s usually left hanging to see a full trailer, even the movie.
Best selling author Tim Ferris has a great post about how he found the optimum time fame, and shares creation and promotion tips. His trailers for The 4 Hour Body and The 4 Hour Chef are some of the best I’ve ever seen which have fuelled his book sales.
