Where you place your reader-magnet link inside a book matters more than almost any other variable in the entire funnel. A well-designed bonus page with a badly placed CTA still converts near zero. Here’s what the placement actually should look like, and why.
Back Matter Is Your Primary Placement
“Back matter” means the pages immediately following the end of your story or content — right after “The End,” or after your final chapter in nonfiction. This is the highest-converting placement for one simple reason: the reader is still holding the book (physically or in an app), still emotionally engaged with what they just read, and hasn’t yet moved on to something else. A CTA here is competing with nothing.
Compare that to a CTA buried in the middle of the book or tucked into acknowledgments before the story even starts — both get skipped because the reader isn’t in “what’s next” mode yet.
Back Matter CTA Example (Fiction)
Thank you for reading [Book Title]. If you’d like the deleted opening chapter told from [Character]‘s point of view, grab it free at [link] — and be the first to know when the sequel goes live.
Back Matter CTA Example (Nonfiction)
Want the printable checklist version of the framework in Chapter 4? Download it free at [link], along with two bonus worksheets that didn’t make it into the book.
Keep it to two or three sentences. You’re not writing a sales page here — you’re making a single, clear, low-friction ask while attention is highest.
Front Matter: Use Sparingly
Front matter — the pages before chapter one — can work, but it needs to be short. A reader who opens your book is there to read the book, not your funnel pitch, and a full page of CTA before chapter one reads as a bait-and-switch that can hurt your reviews. If you use front matter at all, keep it to one line:
Before you start: grab a free bonus scene for this book at [link].
Many authors skip front matter entirely and rely on back matter alone. That’s a reasonable default if you’re only adding one placement.
Formatting Details That Actually Matter
- Keep the link short. A long URL with mixed-case letters and query parameters is nearly impossible to type correctly from a printed page. Use a shortened link.
- Add a QR code for print editions. Ebook readers can tap a link; print readers can’t. A QR code next to the link removes that entirely for anyone reading on paper.
- Don’t disguise it as an ad. A CTA formatted like a sales page (bold headlines, multiple exclamation points, a wall of bullet points) reads as promotional and gets skimmed past. Plain, conversational formatting that matches the rest of your book’s voice performs better.
- Make the offer’s relevance obvious in the first sentence. Don’t make the reader guess why this bonus is worth having — name it immediately.
Should Every Book in a Series Have Its Own CTA?
Yes, ideally with a unique, trackable link per book. This lets you see which titles in your backlist are actually driving signups, which matters once you have more than one or two books — without per-book tracking, you have no way to tell whether book three’s placement is working better or worse than book one’s. This is one of the specific features we cover in our AI Reader Rocket review, which generates a unique link per book automatically alongside a visual mockup of exactly where it should sit in your manuscript.
What to Test Once It’s Live
After republishing through KDP with your new back matter:
- Open the book yourself (Kindle app or a print proof) and confirm the CTA displays correctly and isn’t cut off by page formatting.
- Click or scan the link and confirm it loads your actual bonus page.
- Submit a test signup and confirm it lands in your connected email provider.
- Check that the bonus itself — the file, the discount code, whatever you promised — is actually delivered.
Skipping this step is one of the most common reasons a reader-magnet funnel silently fails for months without the author noticing.
Bottom Line
Back matter, kept short, with a print-friendly link and a clear, book-relevant offer, is the placement that does the most work in this entire funnel. Get that one placement right before worrying about anything else — front matter, additional bonuses, or A/B testing CTA copy are all secondary to simply having a working, well-placed link in the first place.
