Writing success isn't about how many books you sell. Still it is nice to sell a lot of books.
Amazon keeps track of their sales. Under details for a title, its best seller position is noted with #1 being the most sold.

Just for fun I checked a few. The Girl on the Train by Paula Hawkins was number 8.
Liar by Nora Roberts, #115; Finders Keepers by Stephen King, #513; Blessing Way by Tony Hillerman, #34,370.

When checking out writers that may be at Pima Writers' Workshop 2015, the Writers Buffet lists Cynthia Bond. Ruby by Cynthia Bond is an Oprah's Book Club 2.0 pick.  Today Ruby has an Amazon best seller position of  #3,054. Wow!
