How Thou can Count up those Sales?

Recently, I was doing some research for another possible new book in the future. Many Indie Authors are figuring out their own way and producing quite remarkable results indeed.

One Author does their marketing in this manner;
Uses 3 pen names.
Publish across all retailers.
Writes in BBW werewolf romance and psuedo-incest.
Writes new stories each month and uploads them to the platforms.
Writes in series, probably making the first one perma-free.
Prices those books according to length, from .99 – 9.99, books are in 3,000 to 150,00 word count.
Uses paid advertising.

You notice a system in the above? Sure you can see it. Multiple Author Pen Names with many Titles listed under each one makes more sales. Of course, the paid ads put those books in front of readers. The Author uses the book series formula, making the first book free to hook the readers into buying the rest of the series.

Another Author found his way with this;
Writes what they love to write about.
An Active Facebook Page, website and a mailing list.
Uses newsletters to find new readers such as BookBub, BookBlast, etc.
Writes in Series because that is where the most sales originate.
Released a new novel every two months to keep that boost going.
Priced books 2.99-3.99 range.

Here, I laid out examples of two successful Authors basically using the same formula. No need in making this post any longer. By the way, did you learn anything?
