Have you ever seen a book trailer? Probably not, unless you're one of the many authors and publishers who are trying to figure out how to sell books in this market. We spend a lot of time looking at each other's work.
Theater goers are used to seeing trailers on the screen before the feature they've paid to see. Film trailers also get plenty of air time on television and the Internet. There are websites devoted to them, such as Trailer Addict. Unfortunately, there is no practical way of attaching book trailers to books and publishers don't have advertising budgets to pay for them on television.
You would think that someone at Amazon might think of attaching links to them on their website. Maybe they have. I haven't seen them. Surely someone could create a website for book trailers as Trailer Addict did for movie trailers. Then again, why doesn't Trailer Addict include a category for them. (I'm just thinking out loud here.)
I started to make a trailer for Rebels on the Mountain, but got distracted. I decided instead to recreate the experience that readers enjoy when authors visit bookstores and read from their own novels. Don't get excited if you're an author. My idea didn't sell my book any better than your trailer sold yours.
You can search for “book trailers” on YouTube. Their website will return more than a half-million results! Not very helpful, is it? They're divided into categories which may help readers, but it doesn't help authors and publishers sell a specific product.
That leaves us with the ultimate question. Assuming that book trailers or videos of book readings will help sell novels, how can authors and publishers put theirs in front of the right audiences?
