Reader magnet ideas for fiction and nonfiction authors

New to the idea? Start with what a reader magnet is. The best one is not always a whole novel. It is whatever readers of your genre would happily trade an email address for. This guide covers ideas for fiction and nonfiction, how to choose between them, and how to produce one without a huge amount of work.

How to choose the right idea

You do not need a website to give any of these away; see running a reader magnet without a website. Before the list, one principle matters more than any single idea: aim your magnet at the right readers, not the most readers. A free thriller novella pulls in people who buy thrillers. A generic giveaway pulls in freebie hunters who never open your emails. The closer your magnet sits to the books you actually sell, the more of your new subscribers will go on to buy. Pick the idea that best matches your next release, not the one that is easiest to give away.

Fiction reader magnets

• A prequel or origin story. Set up the world or a main character before book one begins. This works especially well for a series, because it leads readers straight into the first paid book.
• A short story about a favourite character. A side character your readers love, given their own moment. Low effort to write, high appeal to existing fans, and a good taster for new ones.
• A deleted or bonus scene. Something readers cannot get anywhere else. It rewards signups with genuine exclusivity and costs you little if you already cut it during editing.
• The first book in a series. Giving book one away free is a proven way to hook readers who then buy the rest. Best once you have several books in the series to sell.
• A themed collection. A handful of flash fiction pieces or short stories around a theme, gathered into one download. Useful if you have shorter work already written.

Nonfiction reader magnets

• A checklist or template. Something a reader can use in the next five minutes. Immediate usefulness makes people sign up quickly and remember you kindly.
• A short guide to one problem. Solve a single, specific problem your book covers in more depth. It proves your expertise and leaves readers wanting the full treatment.
• A resource list. The tools, links, or further reading you would recommend. Cheap to make, genuinely handy, and easy to keep updated.
• A sample chapter. The strongest chapter of your main book, offered on its own. It works best when the chapter stands alone and ends on a reason to read more.
• A mini email course or workbook. A short, practical course delivered as a downloadable workbook. It positions you as a guide and keeps readers engaged over several days.

Ideas by genre

If you want to narrow things down, start from your genre:

• Romance: a meet-cute short story, a bonus epilogue, or a novella about a secondary couple.
• Fantasy: a prequel about how the world or a key character came to be, or a side quest that stands alone.
• Thriller and mystery: a fast, self-contained case, or a prequel that introduces your detective.
• Science fiction: a short story set in your universe, or a piece of in-world writing such as a report or a log.
• Cosy mystery: a short seasonal or holiday case featuring your amateur sleuth.

How long should it be, and how much work?

A reader magnet does not need to be long. A single strong short story, a novella, or a short practical guide is plenty. Quality matters far more than length: a polished short story beats a rushed novel, because readers judge you on what they receive. If you already have shorter work, a deleted scene, or a chapter that stands alone, you may be closer to a finished magnet than you think. Give it a simple cover so it feels like a real book, and you are most of the way there. When it comes to delivering it, our comparison of BookFunnel, StoryOrigin and Storyfinch covers the options.

Frequently asked questions

Can I use the first book in my series?

Yes, and it is one of the most effective options, as long as you have more books in the series for readers to buy next.

How many reader magnets should I have?

One good one is enough to start. Some authors add a second, aimed at a different series or genre, once the first is working.

Does the magnet need its own cover?

A simple cover helps it feel like a real book and improves signups, but it does not need to be elaborate.
