What to measure, when rank is the wrong number.
Sales rank is the number every author checks and the one that says least about a nonfiction book's real job. This lesson replaces it with a one-page scorecard of counts that show whether the book is winning clients, talks or readers.
What you will do after this lesson
- Pick four or five counts that match your book's job.
- Set up the simplest way to collect each one.
- Hold a 20-minute monthly review and decide one change each time.
What sales rank does and does not tell you
Amazon explains its own ranking on the KDP Sales ranking page. Ranks are based on customer activity for your book relative to the activity of other books. They are updated at least once a day, though changes can take up to two days to appear, and recent activity counts more than older activity. A single sale of a very popular book may barely move its rank. And the page says directly that tracking sales rank is "not an accurate way to track your book's activity."
So rank is a relative, shifting signal about recent activity. It cannot tell you whether the operations director you mailed a copy to has read it, or whether the conference organizer who bought 200 copies will book you again. For a book whose job is clients or talks, those are the numbers that matter.
Amazon does give authors useful data. The Author Central home page says authors can see U.S. NPD BookScan data, including sales by geography, and track sales rank and customer reviews there. Use it to see where copies are selling, then move on to the counts below.
Count what matches the job
Go back to the book's main job from Lesson 1. Pick four or five counts from the matching row.
| The book's job | Early counts (move first) | Result counts (move later) |
|---|---|---|
| Win clients | Copies placed with named prospects; follow-ups done | Meetings where the person had read it; new clients who mention it; share of new leads who read it |
| Book talks | Pitches sent; podcast episodes aired | Invitations; paid talks; copies bought by hosts |
| Visibility | Interviews, articles and posts; newsletter issues sent | Newsletter subscribers; inbound messages; invitations |
| Authority | Copies given to clients and partners | How often "I read your book" opens a conversation; bulk orders |
| Help readers or legacy | Copies in the hands of the people it was written for | Reader messages; groups or programs that adopt it |
| Sell copies | Reviews; newsletter growth | Copies sold per month from your sales reports; BookScan data in Author Central |
Early counts tell you whether you are doing the work. Result counts tell you whether the work is paying off. You need both: if the early counts are low, do more; if they are high and the results are not moving after a few months, change who gets the book or what you say with it.
How authors count
These Scribe Media authors count different things because their books have different jobs. Their results are strong, not typical, and no one can promise them.
- Copies placed. Mario Simonyan's firm tracks distribution, not retail sales. It placed roughly 2,000 copies in the first half of 2026 and does not try to tie each copy to revenue (story).
- Copies matched to leads. Michael Erath's firm logs every mailed book by name and company, so when a reader signs up for one of the book's tools, the firm can connect them to the copy it sent (story).
- Share of leads who read it. Ari Meisel found that almost half of the new leads to his business were people who had read the book (story).
- Copies sold against a goal. Ron Thurston set a goal of 1,000 copies of Retail Pride in the first year, and hit it (story).
- Invitations. Matt Shoup's measure was the speaking fee: his first five-figure booking came after the book (story).
How to collect the numbers
Log every copy you give
Name, company, date, reason, follow-up date. A spreadsheet or your existing customer system is enough (Lesson 7 has the columns).
Ask every new lead two questions
"How did you hear about us?" and "Have you read the book?" Put both on your intake form and in your first call notes.
Give the book its own door
Point readers from the book to one page: a free tool, a checklist, a newsletter sign-up. Sign-ups on that page are readers you can count.
Keep an invitation list
Every podcast, talk, article and introduction that mentions the book. Note where it came from.
Save reader messages
A folder for every email or message from a reader. Count them monthly, and reread them when you need stories.
The one-page scorecard
| Count | This month | Last month | Since launch |
|---|---|---|---|
| Copies placed with named prospects | 22 | 25 | 81 |
| Follow-ups done | 18 | 25 | 70 |
| Meetings where the person had read the book | 3 | 2 | 7 |
| Podcast episodes aired | 2 | 3 | 9 |
| New clients who mention the book | 1 | 0 | 2 |
The decision this month: follow-ups slipped from 25 to 18. Next month, block one hour every Friday for follow-ups before mailing any new copies.
These numbers are invented to show the method. Your own will look different.
Review it once a month for 20 minutes. Write one sentence: what changed, and the one thing you will do differently. Over a year, those twelve sentences are the most useful marketing record you will have.
What you cannot measure
Some of what a book does will never fit in a spreadsheet, and that is fine. Nicholas Capman, author of The Passionate Workforce, compares a book's return to a good business suit: nobody expects the suit to close the deal alone, but it is one of the reasons the deal closes (story).
Paul Hobby published Glorious Tension and has run no marketing campaigns for it at all. More than three years after it went on sale, he still gets email from strangers who found it, and it has brought invitations to speak to clubs that had assumed he was not one of them (story). No scorecard would have predicted that. Count what you can, keep the reader messages, and do not let a quiet month on the scorecard talk you out of a book that is still finding people.
