Book Metadata, ISBNs and Pricing: An Indie Author Guide

Book metadata is the information that identifies and describes your book: title, author, description, formats, categories, keywords, and more. Accurate metadata helps readers understand what they are considering and keeps your publishing records consistent. An ISBN identifies a particular publication; it is not a marketing plan or an income guarantee.

Your goal for this stage: a master book-details sheet, a deliberate identifier decision, and a price reviewed against the costs of each sales channel.

1. Create a master book-details sheet

Keep the same core information beside you when completing retailer, distributor, and ISBN records. Small inconsistencies create avoidable correction work.

• Title and subtitle exactly as they appear on the book.
• Author and contributor names, series information, and edition details.
• Language, format, trim size, and publication date.
• Publisher or imprint, where applicable.
• ISBN or platform identifier for each relevant edition.
• Short and full descriptions, categories, keywords, and prices.
• Cover and final file locations, plus a log of changes.

Keep a separate row for each format. Use an approval date so collaborators know which details are current.

2. Write a description for readers

Lead with the book's central promise. For fiction, introduce the character, conflict, and stakes without explaining the entire ending. For nonfiction, identify the reader's problem, the approach, and the practical benefit the book actually delivers.

Use short paragraphs and concrete language. A description should help a reader choose, not list every topic or repeat praise the book has not earned. Compare the finished description with the manuscript: are the promised subjects and experiences really there?

3. Choose accurate keywords and categories

Start with language your intended readers would use. For example, an illustrated beginner's guide to balcony gardening could prompt research into phrases about small-space growing and container vegetables. Treat these as candidates to investigate, not a promise of search demand.

On KDP, follow the current keyword guidance. Use relevant phrases and avoid misleading author names, promotional claims, or unrelated topics. Select categories that describe the book honestly rather than chasing an easy label.

Retailer keyword fields and your website's SEO serve different systems. Write a useful website title and description too, then link related articles naturally so readers can continue learning.

4. Make the ISBN decision before submission

KDP offers eligible paperback and hardcover books a free ISBN, but that free identifier is restricted to KDP. KDP does not require an ISBN for its ebooks. An ISBN you obtain through an official agency can offer different imprint and distribution options.

Read KDP's ISBN options and your relevant national agency's guidance. In the United States, Bowker's ISBN information is a starting point. Do not assume that one identifier can be reused across all formats or materially different editions.

Decide where you want the book distributed before choosing the least expensive identifier route. Verify that the title, author, format, and imprint match the registered record.

5. Price each format using its actual costs

Check comparable books, but also calculate what each sale contributes. Retail list price is not what the author keeps. Production, retailer or distributor deductions, payment processing, shipping where relevant, refunds, and promotion all affect the result.

Use the current KDP pricing guidance and print cost and royalty calculator for that platform. Other channels need their own figures.

A useful worksheet records: format, channel, customer price, expected payout, costs you still pay, and estimated contribution per sale. For a direct sale, subtract the relevant transaction, fulfillment, and delivery costs from the amount retained. Do not subtract a platform deduction again if its payout already accounts for it.

Illustrative planning example: if your contribution after per-sale costs is $5 and your one-time production cost is $500, 100 sales would recover that production cost. This is arithmetic, not a sales forecast; advertising, ongoing overhead, refunds, and taxes may change the result.

6. Test a clear offer rather than constant discounts

A signed print copy, a book-and-workbook bundle, or a group purchase can be a distinct offer when you can deliver it. Give each offer an honest description and its own cost calculation. If it creates more fulfillment work than value, simplify it.

Direct ebook sales require working payment and file-delivery arrangements. Review existing distribution commitments first: KDP Select's digital exclusivity terms can restrict selling the enrolled ebook through your own website.

Metadata and pricing questions

Does an ISBN make a book copyrighted?

An ISBN is an identification tool. It does not replace permissions, rights decisions, or copyright guidance relevant to your book.

Will keywords guarantee more sales?

No. Accurate keywords help describe and position the book. Reader fit, the cover, sample, description, availability, and ongoing promotion also matter.
