I'm still in procrastination mode (need to tie down some final text edits and photo licensing for Eight-Legged Marvels, and haven't quite gotten in the mood to finish Boss Snakes, though I've got the sightings layout done), so just a quick glance (generic musings) at how I think we can categorize online booksales, particularly with POD. Directed (informed) purchases: running along a scale from low need to high need, these are the niche-specific sales for someone who has done their homework and is specifically looking for a book on a certain topic. The higher the need (along with other factors, like few competing titles), the better the chance for an online sale.Casual (recognized) purchases: running along a scale of low value to high value, these are the sales within a community-based niche, where any new title will have a decent chance of being noted, and where purchases are based on past experience (how well previous titles were written), market saturation or over-saturation, and similar factors.Impulse (triggered) purchases: these sales run along a scale from low stimulus to high stimulus, and involve individuals who might otherwise have no real interest in the subject. Factors include cover appeal, and marketing approaches to the title, subject, and scope of the book.A single book can be marketed to each of these purchase categories, but the methods are different. And, of course, a given title may not appeal to certain categories. Labels: books, marketing, publishing
