Amazon’s Amazing and Scary Algorithm

This is a cautionary tale for indie-authors.

Up until around June 23rd, Amazon used to auto-suggest Apocalypse Revolution to readers. For instance, when looking at a product page for a similar horror novel, readers would see this header below the cover page and description  “Customers Who Bought This Item Also Bought.” After that comes the row of about one hundred clickable thumb-nails of novels usually in the same genre. When checking out other horror/scfi adventure novels, I often found that Apocalypse Revolution was auto-suggested.

But it all changed in the third week of June. Now I can only find one novel that auto-suggests AR: The Dragon and the Unicorn, and AR is about the 90th suggestion.

So what happened? Obviously this was not a human decision, except that a bunch of variables were programmed into the auto-suggest algorithm and my novel tripped one of them. Here are my theories:

1) Low downloads on a free day. This is my bad. I waited months for the new cover and then ran three free days close together. That’s a killer for downloads because the hard core readers who are looking for deals will have already downloaded your novel the day or week before and don’t need it. On the last free promotional day I ran there were only forty or so downloads, actually there were more in the UK, only the internet knows why. Here’s my other bad: I didn’t promote the free days at all. I was conducting an experiment to see which cover moved better, but of course I couldn’t run a proper control, so it was a pretty useless experiment.

Maybe the algorithm has a bit of code that says, ‘if free downloads are less than fifty in a day, stop auto-suggesting this novel.’ I’m paraphrasing of course.

2) The six month theory. The third week of June was six months since I published AR. Now I admit I haven’t done a whole lot to promote the novel, and Amazon helps those who help themselves. I’ve been cramming through book two, anxious to get it to market, anxious to get to book three and fill in the gap that takes us to Vampire Road, which is book four. So I wonder if I trip some piece of code that says, ‘if sales aren’t x by six months’ reduce auto-suggest function by an order of magnitude.’ In other words: dump it.

Whatever the cause, the results are startling. AR went from selling one or two copies a day to nada, okay, almost nada, since Amazon turned off the promotional tap.

I’m not too worried. Book Two of the 1000 Souls is the best I’ve ever written, and I think its sales will put me back into Amazon’s favored novel status. But I have learned my lesson. Amazon promotes those who promote themselves. Don’t leave it to luck, because Amazon’s Amazing and Scary Algorithm will cut you off and leave your novel to languish into obscurity. Fair enough. Why should Amazon have to do all the work?

So I’m thinking about book trailers, Shelfari, Good Reads and more. I’ll keep you posted. Any suggestions, send them my way. I’m not a natural promoter, but I’ll learn.
