Advertising.

I talk with a lot of other writers. We always ask one another about advertising and various methods of promotion. Some of the authors I converse with over this topic claim that they do well with advertising on Amazon.com. It makes some amount of logic, as Amazon is very close to becoming a publishing monopoly. They do seem to control access to the marketplace in all other ways, so why not advertising, also?

However, after years of trying out various advertising campaigns at Amazon I have never encountered a situation wherein I profited from putting my money there. That is, no ad campaign returned to me even as much money as I put into it. The opposite was almost always true. If, say, I put $400 into an ad campaign I might get $150 or $200 in cumulative sales over the course of the campaign. Only once did I squeak out a tiny bit of profit from an Amazon ad push, and only by a few dollars.

So, for me, advertising on Amazon is a complete waste of my money, my effort, and my time. My last bit of money spent there advertising my work was, in fact, the last money I will ever spend there for that purpose.

That is all.

I'm not sure why, but my COALITION: Zombie Trilogy is the best selling of all of my books since I republished a number of my titles after regaining publishing rights from a former imprint. It has done well in ebook format, but dollar-wise is doing even better in audio book sales. WORKING CLASS HERO has the edge in total ebook numbers, but the audio of that book isn't nearly as high in sales.
