[Will Write for Gruel]

My book was consistently selling 40 a day for an entire month. (Amazon US) The next month I was selling around 50 until the end of the month where it jumped to 100 a day. The next month it stayed at around 150 for a while, then jumped to 250 then 350. Then that next month it sold 550 each day pretty consistently. Then it jumped to 750 a day for all of Feb. Then it jumped down to 550, then 450 then 350. Rank fell. It was a dramatic drop, not a gentle decline. Now I'm selling about 65 to 70 a day on Amazon US.

My guess? If you sell well, Amazon starts promoting you. At some point they start promoting someone else and your promotions die down.

There's no way I can sell 750 books on my very own. I can't reach that many people by posting on forums or blogs. It wasn't ME. It HAD to be Amazon.

Maybe Saffina's book was listed as 'also bought' on some of the free novels 'selling' really well, so she got a lot of exposure. Then those novels might have gone to "paid" and dropped dramatically down in ranks. That would decrease exposure fast.

All speculation on my part, but there you go.

I agree with this. Amazon promotes. At some point Amazon may slow promotion because they may feel it's better to rotate in new books. Who knows, but if I was Amazon I'd want to see new books in my top 20 periodically. Customers don't want to see the same books over and over.

And really, dropping from #5 to #21 doesn't seem that precipitous a drop.
