The standard way the industry including companies such as Bookscan track book sales is through ISBNs.
All traditionally published books -- paper and electronic -- have trackable ISBNs.
Kindle does not require an ISBN, so few indie publishers use one. Therefore, most indie-published ebooks are NOT being tracked by
these services. Of course, Amazon knows exactly how many ebooks -- trad and indie -- it is selling, but as a matter of policy does not release that information publicly.
The assumption -- and commonly espoused "generally accepted truth" -- that ebook sales are down comes from a decline in ISBN-tracked
ebooks. This includes traditionally published ebooks and indie-published with ISBNs (which also include Apple, Kobo, B&N etc).
It does NOT include the vast majority of indie-published Kindle ebooks.
So, is there REALLY a decline in across-the-board ebook sales?
Only Amazon knows for sure, and for competitive reasons, they're keeping that proprietary information to themselves.
My guess is, people reading traditionally published ebooks are tired of paying more than $9.99, or even that much. I realize some trad publishers have reduced prices on some books, but they're still high overall. Customers are rebelling, and buying fewer trad published ebooks.
And, probably, more indie ebooks. Or borrowing them through KU.
