It may also still be in the experimental phase. I've heard reports of some people not seeing it, even on very high-ranking books.

But since it's only likely to benefit high-selling books, wasn't the ranking enough? This seems a little bit like overkill.

It sounds to me like a keep Trad happy thing.

When they hit a winner, they want Amazon to acknowledge it with something special.

I wonder if this is only on amazon.com - my new release has unexpectedly sold over 200 copies this month

it says "100K+ bought or read in past month."

Slight scale imbalance.

100,000 sales/reads in a month to get that. The quoted book has high level orange tags, which I suspect comes first before the extra note.

I have seen this on some other kinds of products for a while.

From glancing at the discussion on FB, I noticed an alleged Amazon response that makes it sound as if the figure is more than just borrows and reads. It might, for example, include listens. (Amazon uses that data in its Amazon Charts system.)

It seems Amazon is now posting estimates of reads/boughts on the books' pages in small font, right above the synopses. For example, on Freida McFadden's Never Lie page, it says "100K+ bought or read in past month." I thought it might only apply to KU books, so I checked out some wide authors. It's the same for them as well.

Have you noticed these additions on your books' pages? From my brief observations, though, I think this only applies to books selling 100+ per month.
