Depending on the category, roughly 3,000 to 9,000 sales in a week will get you near the top of one of the NYT lists.<p>It&#x27;s basically the same deal as Amazon, but on a bigger scale. Unfortunately it&#x27;s not that much harder to game if you have spare cash and&#x2F;or plenty of friends and&#x2F;or followers and&#x2F;or a significant marketing budget.<p>Not many people understand that sales can peak and dwindle rapidly. Unless you&#x27;re J.K Rowling or George R.R. Martin, many books typically get a week of marketing effort <i>at most</i>.<p>So it&#x27;s not unusual to hit the lists for the first week with - say - 10,000 copies, but only sell another 5,000 - 10,000 copies in the next 12 months.<p>This may be enough of a reason for a publisher to drop an author. Even after a book gets the coveted NYT best-seller tag, total royalties may still not cover a modest initial advance.<p><i>Staying</i> on the lists for a long time is a whole other game, and much more of an accolade than getting on the lists in the first place.
