Now, when it comes to books I am a big believer in developing a video strategy. I'm sure some authors will disagree with me and that's totally cool. But I do think I authors SHOULD at least consider video in their marketing plans. But now I'm going to say something that might seem contradictory. Just because you can do video doesn't mean you should. OK, what does that mean? It means don't make video just to make video. Don't create a book trailer just to have a trailer. Don't do a vlog just to do a vlog. Quite simply, whatever video you make should be germane and specific to your book.
Let's take Suzanne Young's The Naughty List as an example. It's a story about a group of cheerleaders who catch cheating boyfriends. I'm using her book because I have read it and because I know Suzanne and her skills. Suzanne is comfortable on camera. In her case, I would recommend she create a regular video series in which she answers readers/girls questions about how to catch a cheater. These would be done tongue in cheek style -- which is the style in which the novel is written. These could be real questions from readers/girls. They could also be questions Suzanne comes up with on her own. But they should be fun and they should be answered in a playful way. She would answer them as herself, similar to how Liz Lemon answers "Deal Breakers" questions on "30 Rock." I like this idea because it's ongoing. She can use it to build an audience and to broaden an audience beyond her existing readers. These videos also have the potential to go viral as teens pass them around to each other. They drive interest in the book, but they are also broader than the book so can be used to sustain interest in the series and the author.
You can also do the John Green style of video blogs. If you go this route, you should probably be someone who is innately funny and has a sense of the rhythm and timing of short personal style vlogs. Knowing their humor and blogging style, I am betting writers like Stephanie Perkins and Kiersten White would be good for this style of vlog video series.
What if you're not comfortable being on camera? Then think about the elements in your book that you could extract and base a video series on. Is your lead character a star athlete? An opera singer? A musician? Could your character narrate a video about their expertise? Maybe your character bakes awesome cupcakes. You could do a how-to-bake-a-great-cupcake-by your-character video. You could narrate and use various videos as b-roll (that's the video that plays under the narration). My point is there many creative ways to market your stories using video. And just to prove my point, I'll Blentec your books right here! If you want to throw out a synopsis and ask what would be a great video or video series, I will read them all and respond with ideas off the top of my head!
