Amazon Best Seller Rankings

• Amazon ranks books hourly based on how much time has elapsed since the last purchase.
• Rankings are based solely on sales – not on reviews or ratings.
• The rankings are calculated hourly by Amazon, but there is a lag between an increase in sales and an improvement in the rankings.
• The rankings are relative to other products in a category.
• To increase your ranking, you must sell more books than others in the same category.
