I did a little breakdown on a Goodreads thread a while back to try and figure out where most of my orders were coming from. As I recall, the vast majority were from individual requests online. I sent a LOOOOOT of personalized (i.e. "Hey Katie, I saw your last video of you Irish step dancing and it was so cool! I hope I get to see you in person one of these days. Let me know the next time you have a show.
I'm sending you a message because I wrote a book, and I'm hoping you'll give it a chance and check it out." etc etc) messages to individual people, and that method brought in the most orders. And giving away stuff, too. Everyone likes a contest or giveaway.

I got a pretty good response for a few days from pitches, but then it trailed off and no one was responded to those anymore. I think everyone just started sending out so many pitches that people started ignoring them.

I constantly remember a piece of advice from Lindsey Buroker, a self-publishing author that I really respect and admire - she said you pretty much have to hand-sell your first 1000 copies. If you're an unknown author, you have to just go order by order, one person at a time. It's gonna be hard.

But if each of us can get you an order or five, that will help!

@Amanda Orneck Here's my take on it; find your niche. Jamison had tremendous success going to cons and leveraging his in-person presence. Brian Guthrie had similar success by pushing his massive Facebook following and a knack for communicating online. Like Jamison says; it takes a specific personality to do what he did and that can be said of any kind of successful endeavour. You might not have it in you to do what he did, or what Brian did, but you may very well have something completely different yet equally as potentially successful. Look to your strength and find out how to use them to find new readers.
