Covers, titles, and the seven keyword slots

The listing is a machine with three gears

A shopper's decision happens in two heartbeats. First, search results: your cover and title have about a second to earn the click against eight neighbors. Second, the product page: subtitle, description, and reviews have to close the sale, and Amazon's system watches whether searchers who click actually buy, because that conversion pattern feeds your ranking. Gear one is the click, gear two is the close, gear three is the algorithm learning who your book is for. All three are packaging, and packaging is where newcomers under-spend.

Title and subtitle: different jobs

The title matches the search and stops the scroll. The subtitle does everything else: the promise, the specificity, the sub-niche words from your research. One number here is actually enforced: Amazon requires your title and subtitle together to come in under 200 characters (KDP metadata guidelines). Coaches teach a craft guide well inside that cap, roughly 120 to 180 characters, long enough for the promise, short enough to stay legible. Work to the convention, not the cap, because keyword-stuffing a title will get you a policy notice, not more sales.

The enforced rules are mostly content rules: your title field must match what is on the cover, no extra words, no "bestselling," no trademarked terms, no bonus phrases crammed into the subtitle that belong in the description. One publisher's content-review notice gave five business days to strip a keyword-stuffed title before the book was pulled from sale. The winning pattern is the honest one: main title short and clear, subtitle packed with the specific reader and the specific outcome.

Nonfiction: "The Shift Worker Meal Prep Cookbook" beats "Eat Better" every day of the week. Specific noun phrases carry search. Fiction: genre signal first, evocative second; the title whispers the genre and the cover shouts it. Low-content: the niche word is the product. "Funny Hedgehog Journal" loses to "Hedgehog Gifts for Hedgehog Lovers" with the journal described in the subtitle, per the gift-keyword pattern from the research lesson.

Covers: buy this one

The cover does more work per dollar than anything else you will buy in this business. Marketplace data puts the average professional cover design at $880, with most projects on Reedsy falling between $625 and $1,250 and genre medians running $470 to $910, nonfiction near the bottom of that range and fantasy, romance, and science fiction at the top (Reedsy on cover costs). Operator consensus in self-publishing communities points to a solid budget tier around $150 to $250 from working designers who serve indie authors, and below that tier you are gambling the entire book to save one hundred dollars.

Whatever you pay, apply three tests. Thumbnail test: shrink the cover to postage-stamp size; if the title is unreadable or the design collapses, it fails, because that is how most shoppers meet it. Shelf test: place it in a screenshot of real search results for your keywords; it should look native to the genre and better than at least half the neighbors. Genre test: a thriller cover that looks like a cookbook confuses Amazon's classifier and the humans alike; browse the bestsellers in your category and match the visual grammar before you brief a designer.

For low-content, cover design is the product itself, and doing it yourself in a design tool is normal; for everything else, buy the cover or use a designer-marketplace premade that passes the three tests.

Categories and the backend keywords

When you publish, KDP asks for up to three category placements, the browse shelves your book sits on, and gives you up to seven keyword slots, where you enter terms that help Amazon understand what your book is (KDP metadata guidelines, KDP on keywords). Both feed search.

For categories: pick the specific over the broad. Being a small fish in "Cookbooks" is invisible; being visible in a narrow subcategory can put a "best seller" badge on your book in week one, because subcategory bestseller lists are shallow. Operators also report successfully emailing KDP support after launch to request additional category placements; it is a known, legitimate request.

For the keyword slots, the practices that matter: don't repeat words Amazon already knows from your title and category; use phrases, not single words, because shoppers type phrases; don't stuff brand names or other authors' names, both against policy; and vary the angles across slots, one slot for the audience, one for the use case, one for the synonym shoppers might use. The backend keyword slots are not advertising, they are metadata. Clean, specific, honest.

Packaging done, you have a book that can be found and chosen. The remaining gate between you and launch is administrative, and it is shorter than people fear. Save your nerves for the launch; the paperwork will not ask for them.
