Direct answer

A reader magnet is free content (usually a short novella, prequel, short story, or themed guide) given to readers in exchange for newsletter signup. Most indie authors create one reader magnet — 8,000-25,000 words for fiction, 5,000-15,000 words for nonfiction — and use it indefinitely as the newsletter funnel. Conversion rates from landing page to signup: 25-40%.

Chapter i·Why it matters

Reader magnets are the highest-leverage newsletter tool in indie publishing. Authors with strong magnets build 1,000+ subscribers in their first year; authors without one struggle to reach 500. The magnet is built once and produces returns for as long as you publish in the genre.

Chapter ii·What to include

  • A short free work: novella, prequel, short story, themed guide.
  • Length: 8,000-25,000 words for fiction, 5,000-15,000 for nonfiction.
  • Delivery via email tool (ConvertKit, MailerLite) or BookFunnel.
  • A landing page driving signups.
  • Genre fit: same subgenre as your books.
  • A "next book" tease in the back matter.

Chapter iii·Example

A debut romance author writes a 14,000-word prequel novella as her reader magnet. She delivers it via BookFunnel from her website signup page. Year-one signup rate: 32% of landing-page visitors. The 1,840 subscribers she builds before her debut launch convert at 27% on launch day — driving 497 launch-week sales.
