I thought I'd report on my first week's experiences with the Nook First program. Overall, I'm absolutely thrilled that I was able to participate. A brief recap:
The Nook First program includes a variety of marketing promotions on the part of Barnes & Noble. (Note: this is the current program; things might change down the line.) Your book is on the home page, on a special "Nook First" page, and there are email blasts to Nook owners and to everyone who's bought one of your books through Barnes & Noble. Needless to say, you can't get this kind of attention on your own. Not without major effort and expense.
Your book is not free. The minimum price is $2.99. Your book appears with 3 others on the Nook First home page for two weeks, and shows up in "new releases" in whatever genre(s) you've selected when you uploaded the book. So, there's good visibility all over the Barnes & Noble website. And, if your book climbs in the rankings, it'll be in even more places.
The conditions: the book must be a first time digital release, and you have to keep it exclusive to the Nook store for 30 days. After that, you're free to publish it elsewhere. My reasoning in applying for this program was that my Pine Hills Police series wasn't selling particularly well anywhere, so publishing SAVING SCOTT, the new book in the series as a Nook First, might draw attention to the rest of the series. Also, my other promo and marketing efforts seem to target the same general audience.
Did it work?
