Evaluate advertising with the book format and report scope visible. Record which edition the campaign promotes, which products the reported results include, and the relevant contribution assumptions before combining figures across ebook and print editions.
Identify the edition behind the campaign
A title can have an ebook, paperback, and hardcover with different prices, production costs, and reading experiences. A campaign name containing only the book's title may conceal which edition is being promoted. Start the review by recording the actual advertised product and its format, together with the marketplace and reporting period.
Do not infer that identity from the cover thumbnail alone. Several editions may share nearly identical artwork. Use the product identifiers and current campaign details available in the account. The purpose is to connect each observation with the edition a reader could encounter, rather than attributing all activity to an abstract title that combines several products.
Read what the result columns include
Inspect the current definitions of the report you are using. Determine whether each metric concerns the advertised product, another eligible product, or a broader set of attributed activity. Keep any unavailable breakdown marked as unavailable. Do not divide a combined total among formats based on an assumption about what readers probably bought.
KDP's advertising guidance directs authors to the Ads console for campaign performance and explains that Ads and KDP reports can differ in scope. Use the relevant current reporting documentation when interpreting a specific field. The operational question is what evidence the column supplies, not whether its label resembles a number in another dashboard.
Keep sales value separate from author contribution
Reported sales value is not automatically the amount available to recover advertising expense. A print edition has printing costs within its royalty calculation, and the applicable calculation depends on the product and channel. Use the appropriate current royalty information for each format rather than applying one paperback assumption to every sale.
Keep the contribution estimate and its source visible beside the observed advertising figures. If a report does not reveal the necessary format breakdown, state that limitation in the assessment. A precise-looking profitability result built from unknown product mix is less useful than an honest range or an explicitly incomplete calculation awaiting better evidence.
Compare reader expectations as well as numbers
Different formats can serve different tasks. A workbook may be useful for writing in by hand, while its ebook requires readers to respond elsewhere. If the advertised edition and the description imply different experiences, the performance review should include that mismatch instead of treating the issue as a keyword problem alone.
Inspect the relevant detail page and current format presentation. Record any change in price, availability, or book description during the test. These observations do not establish why an individual reader acted, but they identify conditions that affect what the campaign was actually testing. Keep them with the results so later comparisons use the same context.
Avoid declaring a format winner from an uneven test
A paperback campaign with more exposure cannot be compared casually with an ebook campaign that ran briefly or under different conditions. Note the duration, settings, budget, and any interruptions for each observation. A smaller sample may simply leave more uncertainty rather than prove that readers reject the format.
Choose the next question based on the evidence available. You may need to clarify the detail page, collect a more comparable observation, or stop an inconclusive experiment at the planned limit. Do not increase spending solely to force the data toward a preferred conclusion. Keep the decision proportional to what the current test can actually establish.
Summarize the result with its format limits
Write a short assessment that names the edition, period, observed activity, cost, and unresolved questions. If several formats are combined for a title-level view, preserve the underlying records and explain the combination. This allows the author to see the overall experiment without losing the distinctions needed to interpret it.
Use the assessment to make a bounded next decision, such as correcting a format-specific promise or changing one part of a later test. Avoid turning a temporary result into a universal claim that one format always advertises better. The useful outcome is a clearer understanding of this book's campaign under documented conditions.
Frequently asked questions
Clear answers for this publishing decision.
Can I combine ebook and paperback advertising results?
You can create a broader summary when the report definitions and underlying records support it. Preserve the format distinctions and do not treat combined sales value as a single known royalty amount.
What if the report does not identify the purchased format?
Keep that limitation visible. Do not invent a product mix to produce a precise profitability figure; obtain a suitable breakdown or limit the conclusion to what the report actually shows.
Does lower activity prove that readers dislike a format?
Not by itself. Exposure, timing, settings, and the product presentation can differ. Review the conditions and the strength of the evidence before making a format preference claim.
What does this book cost to print and produce, and what should the list price be?
Printing cost follows from the trim, ink, and page count, the list price sets the royalty after that cost, and the production budget should be estimated before generation starts, so compare these numbers before you commit to a format or a plan.
