There is a moment at the end of every erotica story when a reader finishes and sits with the experience for a few seconds before doing something else. That moment is a window. The reader has just had a positive experience. They are still in the world of your story. Their interest in your pen name is at its peak. They are as close to buying another title from you as they will ever be.
What happens next depends almost entirely on what you have put in your back matter.
If the page after your story ends is blank or contains nothing useful, they close the file and move on. If it contains a well-constructed set of recommendations pointing them to the next most relevant thing in your catalog, a meaningful percentage will click through and buy it. Some of those readers will keep going, working through your backlist in a single session.
Back matter is the only marketing you do that reaches readers at the exact moment they are most likely to act. It costs nothing beyond the thirty minutes it takes to set up, and it compounds in value as your catalog grows. Despite all of that, most erotica self-publishers either skip it entirely or treat it as an afterthought. This article covers how to do it properly.
What Back Matter Is and Why It Works
Back matter is the content that appears after the story ends in your ebook file. It is the section a reader reaches immediately upon finishing, before they return to their device’s home screen or library.
The term has a long history in traditional publishing, where back matter typically includes author notes, acknowledgments, indexes, and previews of upcoming titles. For self-published erotica on Amazon, the back matter serves one primary commercial purpose: converting readers who just enjoyed a story into buyers of the next one.
The psychology that makes this work is simple. A reader who finishes a story they liked is experiencing a combination of satisfaction and mild appetite for more. They enjoyed the writing, the scenario, the dynamic. They are not yet done engaging with that experience. They are the definition of a warm lead. The question is whether you give them a clear, easy next step or make them work to find it.
Readers who have to navigate away from the book, search for your pen name, browse your catalog, and click through to a product page lose momentum at every step. Most of them will not complete that journey. Readers who see a cover image and a link immediately after the last page of a story they enjoyed need to do almost nothing. The friction between enjoyment and purchase is minimal. That minimal friction is why back matter converts so well.
What to Include in Your Back Matter
A well-constructed back matter section for an erotica ebook contains the following elements, in roughly this order.
A brief transition line. One or two sentences that close the story experience and invite the reader to continue. Something along the lines of “I hope you enjoyed this story. If you did, here are a few more you might love.” Keep it short and personal in tone. This is not a sales pitch. It is a natural transition from the story into what follows.
Two to four recommended titles with cover images. The cover images are the most visually compelling element of back matter and the primary driver of click-throughs. Readers respond to covers in a browsing context because that is how they discovered the story they just read. A cover image at the end of a book activates the same browsing instinct. Include the cover image, the title, and a one to two sentence description for each recommended title. The description should be pulled from or closely based on your Amazon product page description for that title.
Clickable links. Every recommended title needs a direct, clickable link to its Amazon product page. This is the step most new erotica authors forget, and it is the single most consequential omission in back matter. A reader who sees a cover and a description but has no immediate way to buy the book has to work to find it. Many will not. A clickable link removes that barrier entirely. Link both the cover image and the title text to the same product page to maximize the surface area of the call to action.
An optional email list sign-up invitation. If you are building an email list with a free story incentive, a brief invitation after the book recommendations is appropriate. Keep it to two or three sentences. Name what the reader gets for signing up (the free story), explain what they will receive after that (new release announcements), and provide the sign-up link. This is secondary to the book recommendations and should appear after them, not before.
An optional author note. A brief, genuine sentence or two about your pen name and what you write can add a human dimension that warms readers to your catalog. This is optional and should be cut if it starts to feel like filler.
The Four Rules That Determine Whether Back Matter Works
1. Keep It Focused
The most common back matter mistake is including too much. New authors with growing catalogs feel the urge to showcase everything they have written. Fifteen titles listed in a back matter section is not a discovery experience. It is an overwhelming menu that most readers will not engage with.
Readers at the end of a story are in a specific mood and looking for a specific type of content: more of what they just enjoyed. The back matter should serve that by recommending the two to four titles that are closest in niche, tone, and scenario to the story they just finished. A reader who loved a specific type of scenario does not need to see everything in your catalog. They need to see the next most relevant thing.
A focused back matter with two highly relevant recommendations converts better than a comprehensive catalog listing. If a reader clicks through and buys one of your recommendations, they will find the rest of your catalog naturally through your author page.
2. Always Include Covers
The cover image is the single highest-impact element in back matter, and it is the one most often left out by authors who format their back matter as plain text.
Erotica readers are visually oriented by habit. They discovered your story through its cover. They process recommendations through covers. A plain text title and description requires the reader to construct a mental image of what you are recommending. A cover image provides that image instantly and activates the same visual response that drives browsing behavior on Amazon.
Adding cover images to your back matter requires adding the image files to your ebook manuscript before uploading to KDP. This is a standard formatting step in any word processing software. The images should be the same cover files you used for the product listing, scaled down to a size that displays clearly within the ebook layout. Format them as clickable links to the product pages.
3. Always Include Links
Every recommended title needs a direct, working link to its Amazon product page. Both the cover image and the title text should link to the same URL. This gives readers two easy ways to click through regardless of how they interact with the page.
The Amazon product URL for any Kindle ebook is the listing URL found in your browser when viewing the product page. Use the standard URL format rather than a shortened or referral link to ensure it remains stable. If you are an Amazon Associate, you can use your affiliate link format for the back matter links, which earns you a small additional commission on each sale driven through that link on top of the standard author royalty.
Test every link before you upload the final manuscript. A broken link in back matter is a dead end that wastes the reader’s momentum and the effort you put into building the recommendation section.
4. Update Back Matter When Your Catalog Changes
Back matter becomes outdated as your catalog evolves. A title you published six months ago may have been replaced by stronger performers, or the stories you were recommending may no longer be the most relevant to a given title.
Every time you publish a new story that is a strong match for an existing title, consider whether updating that title’s back matter to include the new release makes sense. A reader finishing an older title and seeing a recommendation for your newest work is a reader you are capturing who would otherwise have had to discover the new title organically.
Updating back matter requires editing the ebook manuscript file and reuploading to KDP. The process takes about fifteen minutes per title and takes effect within 24 to 72 hours. For active catalogs, a quarterly back matter review is a practical maintenance habit that keeps recommendations current and relevant.
Back Matter for Bundles Versus Individual Stories
The back matter strategy for bundles differs from individual short stories in one important way: the reader who just finished a bundle is not looking for individual short stories to buy. They spent money on a collection and had a satisfying multi-story reading experience. The natural next step for them is another collection.
For bundles, the back matter should recommend other bundles in your catalog rather than individual titles. If you have three distinct bundles published under your pen name, each bundle’s back matter should showcase the other two. Bundle readers who click through to buy another bundle generate higher revenue per transaction than any individual story sale and are continuing the same value-oriented buying behavior that led them to purchase the bundle in the first place.
For individual short stories, recommend other individual stories that match the niche, tone, and scenario as closely as possible. If the story is part of a series, recommend the other installments specifically. Readers who liked one entry in a series are the most likely buyers of the next.
How to Format Back Matter Properly in Your Ebook File
The back matter section should begin immediately after the final line of your story. Do not insert a page break that leaves a blank page between the story’s end and the back matter content. Readers who swipe past blank pages are already on their way out of the engagement window.
Use your word processing software to create a clean, readable layout. A brief heading like “You Might Also Enjoy” or “More Stories From This Author” sets the context for what follows. Under that heading, present each recommendation as a block: the cover image, the title as a linked heading, and two to three sentences of description beneath it. Leave clear space between recommendations so they are visually distinct.
The email list invitation, if included, should appear after the book recommendations with a different visual treatment to signal that it is a separate call to action. A simple horizontal rule or extra line spacing between the book recommendations and the sign-up section is sufficient.
Proofread the back matter section with the same care as the story itself. Typos in links, cover images that do not display correctly, and broken formatting all undermine the professionalism that the back matter is meant to communicate.
The Compounding Value of Good Back Matter
The value of back matter grows with your catalog. A pen name with five titles has limited back matter potential because there is not much to recommend. A pen name with twenty titles in a focused niche has an extensive recommendation network where every title is pointing readers toward multiple others, and those others are pointing readers back toward more.
Every new story you add to a focused catalog strengthens the back matter of every title that preceded it. The recommendations become more relevant, the network of connections between titles becomes more comprehensive, and the percentage of readers who find multiple titles in a single session increases.
The authors who generate the occasional sales day where one reader bought ten or fifteen titles at once are almost always authors with well-structured back matter across a deep, focused catalog. That kind of bulk purchase does not happen accidentally. It happens when a reader finishes one story, clicks through to another, finishes that, clicks through to another, and never runs out of relevant recommendations. Back matter is the infrastructure that makes that sequence possible.
Frequently Asked Questions
What is back matter in a KDP ebook? Back matter is the content that appears after the story ends in your ebook file. For erotica self-publishers on Amazon, it typically includes recommendations for other titles in your catalog, with cover images and clickable links to their product pages. It is the section a reader sees immediately after finishing your story, when their interest in your work is at its peak.
Does back matter really increase ebook sales? Yes, meaningfully. Back matter converts readers who just finished a story into buyers of additional titles by providing a direct, low-friction path from one purchase to the next. Authors who structure back matter well report regularly seeing single readers purchase multiple titles in the same session. The conversion rate improves when cover images and direct links are included.
How many titles should I recommend in back matter? Two to four titles is the effective range. Too few leaves money on the table. Too many creates an overwhelming catalog listing that most readers will not engage with. Choose the titles that are most closely matched to the story the reader just finished in terms of niche, scenario, and tone.
Do I need to include cover images in back matter? Yes. Cover images are the single most effective element in back matter because they activate the same visual response that drives browsing behavior on Amazon. Plain text recommendations without covers convert significantly worse. Both the cover image and the title text should link to the product page.
Should I link back matter with my own affiliate links? Yes, if you are enrolled in the Amazon Associates program. Using your affiliate link format for back matter links earns a small commission on each sale driven through those links, in addition to the standard author royalty. The additional income per sale is modest, but across a large catalog with active back matter it adds up over time.
What should the back matter of a bundle recommend? Other bundles, not individual stories. Bundle readers are value-oriented buyers who responded to the collection format. Recommending individual short stories at $2.99 after they purchased a multi-story collection offers less value than they just bought. Other bundles match their buying behavior and convert at higher rates.
How do I add images to back matter in my ebook file? Insert the cover image file directly into your word processing document in the back matter section, then format it as a clickable link pointing to the title’s Amazon product page URL. Most word processing software supports this through the insert image and add hyperlink functions. Resize the image to a dimension that displays cleanly within the ebook layout before uploading the final manuscript to KDP.
How often should I update my back matter? Review your back matter quarterly and update any recommendations that are no longer the most relevant options in your catalog. When you publish a new story that closely matches an existing title, consider whether it should replace or supplement the current recommendations in that title’s back matter. Updated back matter requires reuploading the ebook manuscript file to KDP, which propagates changes within 24 to 72 hours.
