Rules are there to be broken. At least, that appears to be the thinking of many in the UK publishing industry.

For additional clarity, Amazon spells out the guidelines for its KDP publishers:

  • Unauthorized reference to other titles or authors
  • Unauthorized reference to a trademarked term
  • Reference to sales rank (e.g., “bestselling”)
  • Reference to advertisements or promotions (e.g., “free”)
