Leverage Kindle Countdown Deals as part of your marketing program
When you enroll your books in KDP Select, in addition to your KDP royalties, you'll receive a share of the KDP Select Global Fund for all pages customers read the first time they read them via Kindle Unlimited or Kindle Owners Lending Library.
"Kindle Countdown Deals are the primary and extremely effective marketing tool for my books. I prepare a detailed marketing program every quarter to ensure that I have at least one Kindle Countdown Deal running at all times. I coordinate other promotional efforts to coincide with my Kindle Countdown Deals to ensure maximum impact. Kindle Countdown Deals have enhanced the visibility of my brand and resulted in substantial additional sales and Kindle Unlimited page reads. I would strongly encourage KDP authors to use this extraordinarily effective promotional tool." --Sheldon Siegel, author of Special Circumstances
