This is the bit I have to practice at: publicity. I would love it if our books would just magically get picked up by our readers, or even go viral, but, no, we have to work at selling them and that's a fine line between information and spam. We always do an intensive, one an hour or so, tweet campaign around launch time for any book. We've found one tweet an hour can be informative, but doesn't bother folks too much. We also have some lovely folk who regularly retweet us to spread the word, so here's a big thank you to them for their support. :)
We've also posted on all the other social media sites we use regularly, Facebook, LiveJournal, Google+ and we have a newsletter mailing list for anyone wanting to subscribe to our updates, but I think I'm going to have to come up with an ad campaign before I can send out more than one message to those in a week. I'll have to have a think about that one, since marketing creativity is just not the same as literary creativity.
Ah well, I never thought of a career in advertising, but this self-publishing business means I have to be author, agent, publisher AND marketer, so I'm learning!
