No, I'm saying my publisher is in terrible shape. Not TTB--They have a good showing. My sales for 57 days, counting 10 pre-order days = 2 e-copies sold.
For TTBs I would say there is no up and down rank history because of the newness of those titles. There is every indication that their sales were progressively climbing since the start of release.
Dog Ear Publishing has the most thorough overview of Amazon Sales Rank and what it translates to in weekly sales. I got the following matrix from Dog Ear Publishing’s blog.
Amazon Sales Rank (Overall – not Sub-cateogry)
- 1,000 = 90 copies sold per week
- 10,000 = 60 copies sold per week
- 100,000 = 16 copies per week
- 300,000 = 12 copies sold per week
- 500,000 = 1 copy per week
- 1,000,000 = 1 copy per month
These are general figures, but you'll see this little chart (or one like it) around the Internet giving you an approximate overview of books sold as defined by sales rank.
Here's another chart:
Below are estimates based on authors personal experiences.

There's a vast difference in chart stats, to be sure. However, compare my current publisher with TTB new releases. There is NO comparison. You have to take in "spikes" that mean huge sales are showing at That Moment. Ten books bought in one day can really give you a great sales rank, and this could be a result of a recent ad or a new release. A true bestseller would have to be monitored every week or so. Classic books usually stay very high in sales for years and years.
