Last year at the 2012 RT Booklovers in Chicago, I released a first-of-its-kind study that analyzed indie ebook sales data.  Our goal was to identify potential factors that could help authors sell more ebooks.Last week at the 2013 RT Booklovers convention in Kansas City, I shared new, updated data in a session titled, Money, Money, Money — Facts & Figures for Financial Payoff.  Now I’m sharing this data and my findings with you.

Some of the results were surprising, some were silly, and some I expect will inform smarter pricing and publishing decisions in the year ahead.

For the study this year, we analyzed over $12 million in sales for a collection of 120,000 Smashwords ebooks from May 1, 2012 through March 31, 2013.  We aggregated our sales data from across our retail distribution network, which includes the Apple iBookstore, Barnes & Noble, Sony, Kobo and Amazon (only about 200 of our 200,000 titles are at Amazon).  As the world’s largest indie ebook distributor, I think our study represents the most comprehensive analysis ever of how ebooks from self-published authors and small independent presses are behaving in the marketplace.

As I mention in my free ebook, The Secrets to Ebook Publishing Success, its helpful to imagine dozens of levers and dials attached to your book that you can twist, turn and tweak.  When you get everything just right, your book’s sales will increase through viral through word-of-mouth.  In my Secrets book, I refer to these tweakable things as Viral Catalysts.  A Viral Catalyst is anything that makes your book more available, accessible, discoverable, desirable or enjoyable to readers.

This survey attempts to identify Viral Catalysts by analyzing the common characteristics of bestselling (and poor-selling) Smashwords ebooks.

We posed a series of questions to our data – including several new ones – to reveal answers that might help authors reach more readers.

The questions included:
