Amazon Sales Rank—Why Does It Matter to Customers?


Obviously, sales rank is important to Amazon. It makes sense to showcase products that are more likely to sell, and those that have been selling frequently have a proven track record. Sales rank factors into bestseller lists, ordering of search results (to some extent), visibility with special features, etc.

Sales rank is also important to authors and publishers. It helps to show how the book is selling.

Perhaps the strange thing is how important sales rank is to customers.


Do people like to buy what’s popular? Aren’t there people with their own sense of style, who want something nice of their own that few other people are enjoying? Some clothes are highly popular, yet you still see a large percentage of people who are uniquely attired.

A few times in the past five years Amazon’s sales rank has been down for several hours to a few days. Sales tend to drop off during this period. Usually, no sales rank means that book has never sold. Suddenly, books that usually sell a few copies per day stop selling while the sales rank feature is temporarily disabled. Why? Because having no sales rank versus a rank of 30,000 can have a significant impact on a buying decision.

It’s like many customers are thinking, “If it’s not good enough for everyone else, it’s not good enough for me, either.” This seems to be a prevalent opinion in the well-educated, well-read world, at least as it applies to book-buying decisions.

There are a few customers who will take a chance on a book with a sales rank in the millions, but not many, and certainly not enough to go around for the millions of books that have received this fate.

Not a Constant

It’s funny when a book that spends most of its time with a sales rank in the millions suddenly sells, and sometimes sells a few more copies that same day. The only thing that has changed recently is the sales rank.

However, while a sale does drop the sales rank considerably—it can drop down to 100,000 from the millions—very often it doesn’t spark more sales. That’s because sales rank combines sales from the past day, week, and month. When a book that rarely sells suddenly sells, its sales rank drops down near 100,000, but rises very quickly. There is a narrow window of opportunity for customers to discover the book with that low sales rank before it returns to its home country.

In contrast, when a book that normally sells every day stops selling for a while, its sales rank climbs much more slowly.

In this way, the deck has been stacked. Hot sellers have a distinct advantage; slow sellers are inherently disadvantaged.


This does make sense in many ways. If a book truly is lousy, its sales rank should skyrocket and that book should become less visible.

In other ways, it can seem unfair. There are tens of millions of books on Amazon. It’s absurd to think that only 100,000 are good and 30,000,000 are lousy.

What about books with a very tiny audience? Even if the book is excellent, sales are limited.

How about books that don’t fall into any standard categories? Even if the book is wonderful, it’s hard to find.

There are a number of reasons that a book can be very good, yet not sell well.

Unfortunately, there are also many books that don’t provide a good customer experience: ridiculously short (just a few pages), very poorly written, major formatting issues, etc.

For many customers, the simple solution is to buy books with a track record of selling well—i.e. look for a low sales rank.

Indeed, many customers only shop bestseller lists.

This gives big publishers and popular authors a distinct advantage. A large preexisting fan base gives rise to many early sales. At the same time, these books have a history of providing customers with good reading experiences, so this advantage has been earned.

The new author who throws a book out there has a distinct disadvantage. It takes time to get discovered and by the time a few readers have tried it and found it to be very good, the history of slow sales makes it a challenge for the sales rank to rebound.


Many publishers and authors do premarketing—sending out review copies, creating buzz, going on blog tours—hoping to stimulate early sales, knowing how much this can impact the fate of a book.


A few people may try to abuse the sales rank factor, but probably in many cases to no avail. For example, Amazon could easily track authors who buy several copies of their own books and factor this into sales rank (if it’s not already done, it could change). If a lousy book does manage to acquire a low sales rank number, the Look Inside and reviews are likely to expose it for what it really is.


You can look at sales rank as a hurdle, in the sense that it takes sales to get sales.

Or you can look at sales rank as an opportunity.

Self-published books aren’t penalized compared to traditionally published books and popular authors. Any book that sells well improves its visibility. A self-published book that sells 20 copies today will compete in visibility with a traditionally published book that sells 20 copies per day.

Daily sales matter much more than weekly or monthly sales. Monthly sales determines how slowly or rapidly sales rank climbs when a book isn’t selling. When a book is selling, it is daily sales that matters.

This means that a traditionally published book that’s sold thousands of copies in the past still needs to sell copies today to compete with a newly released self-published book. In this way, the playing field is surprisingly level.

Sales rank tends to reward books that help themselves. If you write a highly marketable book, have a cover that attracts your target audience, write an effective blurb, have an engaging Look Inside, and the book generally pleases an audience, all this is on your side: It will help your book get discovered and sell when it gets discovered. Every sale helps your sales rank.

If you also do effective marketing, every sale helps even more. The more sales you stimulate through good content and effective marketing, the more sales rank helps you rather than hurts you.

This is why there are many indie authors achieving some measure of success. The opportunity is yours, too.


Another way that sales rank matters to customers has to do with reviews.

Many customers look at the number of reviews and the sales rank.

If a book has several reviews, but a large number in the sales rank, the customer may be suspicious. How did the book get so many reviews without selling?

Of course, there may be a simple explanation:

  • Sales rank isn’t a constant. Perhaps the book was a hot seller when it first came out, but has now saturated the market.
  • Maybe the author has done some effective, temporary promotions in the past. A freebie can give out thousands of copies of the book without directly improving sales rank.
  • Advance review copies may have helped to get some early reviews.
  • The book may have been out for several years and sold thousands of copies, but just doesn’t have a great sales rank presently. Checking the publication date can help with this point.

But many customers will wonder if there is another simple explanation:

  • Were the reviews posted by close friends and family members?

Regardless of the actual reason, this perception can limit the sales of a book that has good reviews, but not a sales rank to match.

A Problem for Amazon?

There is one way that Amazon may be shooting itself in the foot with sales rank: It may be limiting growth to some extent. Five years ago, if a paperback book sold, its sales rank dropped down to about 50,000. Now, this number can be closer to 200,000, depending on the season. Why? Because there are more books, and more books that are selling about one copy per day on average or better. The change is even more extreme with Kindle.

The more books that sell well, the more books there are with higher sales rank numbers that are selling better than they seem.

In previous years, a Kindle book with a sales rank of 350,000 wasn’t selling at all. Now, it’s selling occasionally, and 1,000,000 is not selling at all.

The numbers are changing, but the perception doesn’t change with it. People still look at that Kindle book with a sales rank of 350,000 and think, “That book never sells.”

If there are now 200,000 books selling about one book per day on average, it will be hard for the number of books selling about one book per day on average to climb up to 1,000,000 because of this perception. If Amazon wants to have more books selling at least once a day, sales rank is working against this. Amazon wants to sell more books overall. It may be hard to increase the frequency of top sellers. It might not be as hard to “double the tail,” i.e. double the sales frequency of books at the bottom, without disturbing sales at the top.

The Good Old Days

When you stand in a bookstore, you have no idea which books are selling well.

(Okay, the bestseller lists and books that indicate bestseller status on the cover are a couple of exceptions.)

For the most part, when you stand in an aisle looking at a shelf, you have no idea which books have sold recently and which haven’t.

(Okay, if you’re a frequent customer, maybe you can remember the contents of the shelf well.)

You do see several copies of a few books, and only one copy of most books. If there are several copies, is that because it’s a hot seller? Or are there so many copies left because it hasn’t been selling?

Imagine if you saw the sales rank on every book. You pick up a book, see the number 462,165 on it. You drop it like a hot potato. You better go wash your hands with soap and warm water.

Gosh, ten years ago I used to pick a book based on the cover, spine, back cover blurb, and especially how the first chapter began. There was no sales rank. There were no customer reviews (unless you want to count glowing quotes on the first page and back cover).


How do you shop for books? Is sales rank important to you?

If you feel that sales rank should be important to customers, you can market this perception to others.

If you feel that sales rank shouldn’t be so important, you can market this perception.

You have the chance to discuss sales rank with others and to debate (professionally and tactfully) the pros and cons of factoring this into a purchase decision.

  1. I must admit, I pretty well ignore the ratings list. I think if all readers followed it strictly and bought only what ranked top, they’d end up with a lot of old favorites and classics – not necessarily a bad thing, but hardly new material. Fortunately (as far as I understand it), a lot of people enjoy the shopping/exploring experience. At least I hope so.

    • I also ignore it when shopping, but note from experience that most factor it into the buying decision in some way. Most people want the sales rank to be under 200,000 or so. This includes a wide variety of books, much more new material than classics. If the sales rank is “too high,” whatever that is for a customer, he/she seems to be thinking, “What’s wrong with this book that it isn’t selling?”

      It works both ways, though. Some customers see a sales rank like 3,000 and wonder, “What’s so great bout this?”

      There are many customers shopping/exploring outside of the top sellers, but there are also many books in that domain, and sales rank does hold some influence for many customers. Fortunately, with millions and millions of shoppers, there are people who think all different kinds of ways.🙂

      • There’s also the fact that new books won’t rank well, not having had the chance to. Presumably those who judge the worthiness of a book by rank have figured out all the ins and outs and know, too, how the numbers have shifted in value over the years. Personally, I prefer to make up my mind going by the teaser page and the opening of the first chapter, but then I’m probably classed as old-fashioned.🙂

      • Actually, books that sell right away get sales ranks very quickly. Sales rank doesn’t matter to me as a customer. I can see from discussion boards that many customers who weigh this with importance aren’t familiar with many of the changes, oddly.

        Personally, I wouldn’t mind seeing fewer people rely on this number.🙂

  2. As a reader I never looked at rank when purchasing a book. To me it was just an Amazon thing, because I once bought all my online books somewhere else until Kindle came out with an app for iPad. I did not even realize such a thing existed until I became an author. Once directed to it, and having a promo that improved rank, I began paying attention to it. Now I notice it on all books I browse online, but it doesn’t sway me in one direction or another.

    I have a friend in GA who is in his seventies, Michael Bishop. He has been writing sci-fi all his life and published traditionally. One of his books was even made into a movie (“Brittle Innings”, not a sci-fi). He just released a paperback and none of his books are available in digital form. His books all rank 1,500,000 but I am certain that it is a very good book, only because I have read other works by him. Is it that people don’t want paperbacks anymore…or they aren’t selling as well? My digital is in 100,000 right now, but my paperback is also, 1,000,000. Is there a different formula? I can see workbooks ranking high, you need them as reference books, but fiction? I don’t know.

    • I think knowledge of sales rank is spreading with indie publishing. Now there are so many authors, millions of people are familiar with sales rank either from experience as an author or having a friend or family member who is. Five years ago, sales rank didn’t seem to influence sales (either by stimulating them or deterring them) nearly as much.

      Some traditionally published books sell primarily through other channels, such as bookstores, so there are some traditionally published books that sell 1000 to 10,000 copies in a year, but have an Amazon sales rank in the millions. There are also books, even indie published, that mostly sell to schools, after presentations, in book clubs, etc., which may sell overall far more than the Amazon rank suggests. (Such books can get many non-verified reviews, yet have a poor sales rank.)

      I’m one of the oddballs, with nonfiction books and workbooks, who mostly sells paperback.

      I’m guessing many indie authors are more likely to understand a book with a sales rank in the millions and give it a chance (at least, judge it by the Look Inside).🙂

  3. I didn’t even know that was available to look at until I published my poetry. And then I still had to have it explained to me. With the millions of books that have been published since the beginning of time, it just doesn’t make sense to look at that if I’m going to base whether or not to buy/read a book on that, I could be getting a book that is totally not the right book and missing out on so many other books. I do admit, however, to buying books based on the cover though. It does create a first impression. But reading is so subjective. I like to check out the sample of a book to see if I think it might be for me – plus the book synopsis.

    • I’m glad to see comments from shoppers who don’t weigh sales rank heavily. That’s a nice sign.🙂 I don’t consider sales rank when I’m buying; the Look Inside is probably the best indicator if a book is for me.

  4. There’s another factor in this and it has to do with how Amazon chooses to feature books. A fellow writer and I accidentally tried the Kindle Countdown Deal for our novels at the same time. His was included in the Featured Authors section of the Countdown Deal website the entire time he was participating in the promotion. I don’t know what his sales figures were but his book reached the low 700s in the sales ranks for the Kindle Store. My book never got in the featured section. The best ranking I got during the promotion was about 16,000, and as of today, the sixth day of the promotion, it had produced 32 sales. I’m not begrudging my friend’s success and I’m not sneezing at 32 sales in less than a week, but it seems like Amazon could actually produce more sales for more authors if the Featured sections had books rotate in and out rather than sticking with the same ones for the entire period of the promotion. My friend’s book wasn’t the only one that stayed in the featured section the entire week.

    And the other piece of randomness is how they rank books in other sections. In the genre section for my book, there were books that were older than mine, had a worse sales ranking, fewer reviews, and lower average ratings, yet were listed above mine. How in the hell does that make sense? And, that’s what drives me crazy about Amazon — for all their algorithms and calculations, there a bunch of glitches in it that end up hurting a lot of us little people.

  5. I also love your comparison to how shopping habits have changed. I, too, love the book store experience and not being tied to the information Amazon provides. Just looking at the cover and reading the little blurb and making the decision to buy. Now, as a result of Amazon, if it’s not an author I know, I don’t typically go buy sales rank, but I have started looking at reviews, frequently paying more attention to the low reviews than the high reviews.

      • Yes … I typically don’t give them a lot of credence. What I look for is whether the one star reviews are posted by stupid people acting stupid (I ordered this book and it took too long to arrive so I’m giving it one star or I loved this book, but hated the ending) or whether there is actual substance to the negative reviews. Rarely do I stop from buying a book because of the negative reviews, but frequently they can be more instructive than the cheerleading reviews. I personally believe that any person who reads a book to its conclusion should not be able to give the book a one star review. If the book held you enough to complete the thing than it was better than one star.

  6. Ican honestly say I never bought a book because of its sales rank. I don’t even know where to look for it – and I have never looked at the sales rank on my book. Kinda afraid to see that!🙂 Maybe I’m missing something.

  7. As an innocent reader in the past I would never have looked at ranking only at reviews when buying. Now as a writer, aware of the murky behind the curtain machinations, I feel my innocence has been stolen.
