Free is the most powerful discovery tool in indie publishing and the easiest to waste. A free day on Amazon can pull tens of thousands of downloads β but downloads alone earn nothing; the value arrives only when those readers flow into paid sequels, newsletter sign-ups and reviews. That flow is engineered, not accidental: the free book must be a series opener or funnel title, the follow-through books must be priced to earn, and the promotion must be timed around KDP Select's free-day allowance and promo-site features. This guide covers the three main plays β free days, permafree openers and countdown deals β and the honest maths of when each one pays.
Free is the oldest trick in book marketing β and the easiest to get wrong. A guide to making free promotions, permafree first-in-series books and countdown deals actually feed paid sales.
Five free-book promotion days per 90-day KDP Select enrolment, plus the option of countdown deals. The exclusivity requirement (ebook available only on Amazon while enrolled) is the trade-off for the promotional tools and Kindle Unlimited page-read earnings.
A book kept permanently at $0.00, usually the first in a series, to pull in readers who then buy the paid sequels. On Amazon it is typically done by pricing free elsewhere and having Amazon price-match, since KDP itself will not let you set $0.00.
Yes, when the funnel is built first: the free book must end with a call to action toward book two and your email list. Realistic results are a modest conversion of thousands of downloads into paid sales and reviews β not a windfall, but a genuine discovery engine.
