The launch may be over, but the book sales should not end. Establish a simple system for 'evergreen' content.

Four-month evergreen plan

  • Monthly mini update post and success story
  • Campaign and coupon refresh every two months
  • Shared results of user testimonials
  • Natural upsell opportunity for a second product

If the system is not refreshed at least once every 90 days, sales trends will gradually decline.
