When is the right moment to redo the cover of a book whose sales have stalled?

There is a point at which every author with sales below expectations reaches the same question: is the problem in the book or in the cover? It is an uncomfortable question, especially for someone emotionally invested in the appearance of their own work. But it is a question that needs to be answered with data, not feeling.

The good news is that the cover is the easiest variable to change in an already-published book. The content would require a complete revision. The genre, rewriting. The cover, swapping. And there are widely documented examples in the publishing market of books that multiplied their sales after a cover redesign — without changing a word of the text.

This article answers the question directly: when the sign that the cover is sabotaging sales is clear enough to justify investing in a redesign — and how to run that process intelligently.

1. Why the cover can be the problem — even when the book is good

A book's cover performs two functions at once: attracting the right reader and communicating to the wrong reader that the book is not for them. When it fails at either of these functions, sales suffer — regardless of the quality of the content.

A book with a cover that communicates the wrong genre will attract readers who will be disappointed by the content — resulting in negative reviews that undermine future sales. A book with a cover that does not stand out in the competitive context of its niche will be invisible — neither attracting the right readers nor repelling the wrong ones. Simply not being seen.

On e-commerce platforms, where the cover is displayed as a thumbnail of less than 100 pixels, these problems are amplified. A design that looked adequate at full size can be completely illegible as a thumbnail — which translates directly into a low click-through rate and invisibility in the platform's search results.

The figure publishers take seriously

Cover redesigns of backlist books — works published more than two years ago with sales below their potential — are a regular practice at large publishers. The investment is relatively low (only the design, without rewriting the book) and the return can be significant. American publishers document increases of 20% to 300% in a title's sales after well-executed cover redesigns. In Brazil, the phenomenon exists but is less systematically monitored.

2. How to tell whether the problem is the cover or the content

Before investing in a redesign, it is essential to make the correct diagnosis. Reworking the cover of a book with a content problem will generate a spike in sales followed by negative reviews — which can be worse than the original stalled sales. The diagnosis precedes any redesign decision.

The data that reveals whether the problem is cover or content

The most precise distinction between a cover problem and a content problem comes from the combined analysis of two indicators:

• Conversion rate on the product page: if many people visit the book's page but few buy, the problem may be in the blurb, the price or the first pages of the sample — not the cover

• Click-through rate on the thumbnail (CTR): if few people click the cover when it appears in the search results, the problem is in the cover — it is not generating enough interest to prompt investigation

A low CTR combined with a high conversion rate on the product page clearly points to the cover. A reasonable CTR combined with low conversion points to the product page. Both low can indicate problems in multiple dimensions.

The review test: what readers who bought it say

The reviews from those who have already read the book contain important clues for the diagnosis. If the set of reviews is positive — readers liked the content — the problem is probably in the discovery (cover, CTR, visibility) and not in the product itself. If the reviews include patterns like "not quite what I expected" or "I thought it was a book about X but it was about Y", the problem may be one of genre communication — which is solved with a cover that correctly communicates what the book is.

The clearest sign of a cover problem: readers say the book surprised them positively

When a book accumulates reviews that say "surprisingly good" or "didn't expect to like it so much", it is frequently a sign that the cover created expectations different from the real content. The book is good — but the cover is not communicating that quality to the right readers. The result: few buy, but those who do are satisfied. A redesign that aligns the cover with the content tends to increase both the sales and the satisfaction rate.

3. The specific signs that indicate it is time to rework

With the diagnosis done, there are specific situations in which the decision to rework the cover is clear — not just desirable, but strategically indicated.

Table: diagnostic signs and next steps

The book has existed for more than three years with no visual update

Visual genre conventions change. Covers that were modern in 2020 can look dated in 2024 — because the market evolved, new illustration styles emerged, typographic trends changed, and the palette that dominated the genre was gradually replaced by another.

A reader who visits bookshops regularly has that updating of references happening continuously. When they see a cover using the style of three years ago next to recent covers, they notice the mismatch — even without being able to name what they are seeing. The result is a perception of an old or outdated book, regardless of the content.

The book is going to be relaunched in a new channel or market

One of the situations in which a cover redesign is most clearly justified is the relaunch: when the book is going to enter a new platform, reach a new market or be relaunched with a new publisher. In these contexts, the redesign is not just an update — it is an opportunity for complete repositioning that can reach readers the book never reached with the original cover.

Understand how the cover works in each distribution channel: Is the cover really the most important marketing element in the purchase decision?

The original cover was created without a professional process

Many authors who published their first books with covers created in free tools or by designers without specific editorial experience reach, after some time, the conclusion that the cover was never up to the level of the content. That is one of the redesigns with the greatest potential return — because the starting point is very low and any professional improvement represents a significant qualitative leap.

4. When not to rework — the cases where a redesign is not the solution

Reworking the cover is not always the right answer. There are situations in which the investment will not generate the expected return — and recognising them is as important as recognising when to rework.

When the problem is in the content, not the cover

If the book's reviews are consistently negative — readers who bought it and did not like it — changing the cover may even temporarily increase sales, but it will result in more negative reviews. In that case, the book needs a content revision before any redesign.

When the niche is too small for the scale to justify it

Books written for very specific niches — institutional publications, highly specialised academic works, books for closed communities — can have sales naturally limited by the size of the market, not by the design. A redesign will not expand the market; it will only change the cover of a book with structurally limited sales potential.

When the book already has a base of loyal readers and the redesign could confuse them

Series with loyal readers who recognise the work by its design have more to lose than to gain from a radical redesign that is not accompanied by the previous volumes. In that case, a gradual update — keeping the series identity elements while modernising the look — is more appropriate than a complete repositioning.

The redesign that worsens sales

There is a scenario authors rarely consider: the cover rework that results in even lower sales than before. That happens when the new design communicates a different genre from what the book really is — or when the new cover is more generic than the original. A poorly executed or poorly directed redesign can be worse than the original cover, however good the original was. That is why the process needs to begin with a precise diagnosis and a competitive analysis of the niche — not just with aesthetic dissatisfaction with the current design.

5. The redesign process: how to run it to maximise the return

Once it is confirmed that the redesign is the right decision, the process needs to be run with the same rigour as a first-launch cover — and in some respects with even more care, because there is a sales history and a readership that need to be considered.

Step 1: an updated competitive analysis

Before any creative decision, the designer needs to do a current analysis of the genre's market — not the market of when the book was launched. The covers leading the niche's sales today are different from those leading two or three years ago. The redesign needs to be relevant to the current market, not the past one.

Step 2: a specific diagnosis of what needs to change

The redesign does not need to be radical to be effective. In many cases, what needs to change is specific: the legibility of the title as a thumbnail, the palette that communicated the wrong genre, the typography that looked amateur. Identifying the specific problem avoids throwing away what works in the current design.

1. Is the title legible as a 100px thumbnail? If not, the typography needs to change.

2. Does the palette communicate the right genre? If not, the palette needs to change.

3. Is the image generic and recognisable as stock? If so, it needs an exclusive image or a distinctive treatment.

4. Is the visual hierarchy clear? If not, the composition needs revising.

5. Does the design look dated relative to the current competitors? If so, the visual style needs updating.

Step 3: test before publishing definitively

One of the advantages of a redesign over a first-launch cover is that there is a database for comparison. Before replacing the cover on every platform, the designer can create mockups of the new cover and test them with genre readers — showing the new cover next to the old one and the competition to assess which generates more interest.

Platforms like Amazon KDP allow the cover of an already-published book to be replaced without creating a new product — which means it is possible to swap the cover, monitor the CTR for a few weeks and compare with the previous history.

The A/B test any author can do

Before investing in a complete redesign, there is a simple test: create a mockup of the new cover and show it to groups of genre readers — in Facebook groups, reader Discords, or simply by asking friends who consume the genre — asking them to choose between the current cover and the new one. If the new cover wins consistently, the redesign is justified. If the current one wins frequently, the problem may not be the cover.

6. What changes and what stays in a redesign

A frequent question from authors considering a redesign is: do I need to change everything, or can I keep some elements? The answer depends on the diagnosis — on what specifically is preventing sales.

Table: redesign scopes and what changes in each

The title and author name never change

Regardless of the scope of the redesign, the book's title and the author's name stay the same. These elements are the work's fixed identity — changing the title of an already-published book creates confusion for readers who already know it and can harm the SEO accumulated on the platform (the reviews, the rankings, the sales history stay associated with the original title).

Reworking the cover requires reworking the back cover too

The back cover — the reverse of the cover with the blurb, the author photo and the identity elements — needs to be reworked along with the front cover. A new front cover with an old back cover creates an immediate visual discontinuity any reader notices on turning the book over. The redesign needs to be treated as a complete project, not as replacing only the front image.

Understand how the cover and back-cover decisions integrate: Why can a badly designed cover hurt a book's sales, even with quality content?

7. The expected return: what is reasonable to expect from a redesign

One of the most practical questions about the redesign is: what is the expected return? The honest answer is that it varies — and depends on multiple factors that go beyond the quality of the new design.

Factors that determine the return on the redesign

• The quality of the diagnosis: a redesign that solves the right problem (a cover communicating the wrong genre, a title illegible as a thumbnail) has a much greater return than an aesthetic redesign with no diagnostic basis

• The quality of the new design: a mediocre redesign may generate no return. A redesign that puts the book at the same visual level as the niche's leaders can be transformative

• The content's potential: a book with positive reviews and quality content has a much greater potential to respond to a good redesign than a book with mediocre content

• The book's lifespan: books that have just come out can still recover sales with any intervention. Books several years old with a history of low sales have a smaller starting base, but a potential for reversal in niches with few competitors

Realistic expectations

A well-executed redesign of a book with good reviews and a clear cover problem can double or triple sales in the first month after the swap. In cases of reworking niches with little competition or repositioning for new markets, the impact can be even greater. In cases where the problem was multiple — a bad cover + a weak blurb + an inadequate price — the redesign alone can improve, but not transform, the results.

Frequently asked questions about cover redesigns

How much does a cover redesign cost compared with an original cover?

The cost of a redesign is similar to that of an original cover — because the creative work involved is the same. The brief, the market research, the concept, the execution and the technical file preparation are stages that repeat regardless of whether it is a new cover or a redesign. What can save time is the brief — since the author already knows the book well, they tend to provide more precise references and approval tends to be quicker.

Do I need to formally relaunch the book to change the cover?

On POD platforms like Amazon KDP and IngramSpark, replacing the cover is done directly in the author's dashboard without needing to create a new product. The book keeps its sales history, reviews and ranking — only the cover image is replaced. For books with an offset print run, it is necessary to print a new run with the new cover; the copies from the old run with the original cover continue to exist independently.

Should I tell readers the cover is going to change?

For authors with an active reader base on social media, announcing the redesign can be a marketing opportunity. A post showing the old cover and the new one — explaining that the book has been given a new look — generates curiosity, engagement and can reactivate the interest of readers who knew the title but had not bought it. For authors with little social-media engagement, a silent swap is equally valid.

If the new cover doesn't work, can I go back to the old one?

On POD platforms, yes — you can replace the cover as many times as you need, and the previous files can be kept for future use. Monitoring the CTR and the sales in the weeks following the swap is the most direct way to assess whether the redesign is working. If the indicators do not improve in four to six weeks, it is worth reviewing the diagnosis before deciding between reverting or adjusting the new design. How is a cover mockup created before final approval?

Conclusion: the redesign is a business decision — not one of vanity

Many authors' reluctance to rework the cover of books with weak sales frequently has an emotional origin: the cover represents the effort of creation, the moment of launch, perhaps a personal aesthetic attachment. But the cover is not a monument to the author's effort — it is a marketing tool that has to work in the market where it competes.

When the data shows that the cover is failing at that function — whether by communicating the wrong genre, being invisible as a thumbnail, or looking dated relative to the competition — the redesign is a clear business decision. One of the most efficient available, in fact: the book's content does not need to change, the price does not need to be reduced, the distribution does not need to be reconfigured. Only the packaging.

The book is the same. The opportunity to find the right reader begins with a new cover.
