Case study: grading my own listing first
Before asking anyone to trust these tools, I'm running them on my own book, in public. Here's the baseline. The changes and results come next.

Rank is a snapshot of one moment. It moves hourly and isn't a sales figure. We'll log it daily for a baseline period before changing anything.
The description as it reads today
This is a nonfiction book, so the mystery-specific checks (sleuth, crime, subgenre signals) are switched off. Only the general checks ran. The main case study will use one of my mystery novels.
Blurb score from the Clue to Cart grader in “Nonfiction (general checks only)” mode, run on the live description on Oct 17, 2026. 192 words.
Blurb evidence
- ClearLength192 words. Most genre-fiction blurbs land around 150–300 words.
- FixOpening hookOpens with a generic or rhetorical lead-in (“Are you facing criminal charges or worse yet, been arrested …”).Open on one short, concrete line: who, plus what went wrong. e.g. “The body in the bakery freezer belongs to the man who tried to buy Maggie’s shop.”
- ClearSpecific, not vagueNo stock vague phrases found.
- ClearShows instead of praising itselfNo self-praise in the body copy.
- ClearSkimmable paragraphs4 paragraphs.
- CheckSentence lengthAverage 24.0 words per sentence.Split long sentences. Short sentences build tension.
- ClearEnding leaves a questionThe last line leaves the reader with tension or a question.
- ClearKDP metadata guidelinesNo URLs, prices, time-limited promos or review requests found.
Title line evidence (title score 100)
- ClearTitle + subtitle length85 characters combined. KDP allows 200 or fewer.
- ClearEasy to scanTitle is 10 characters. KDP notes shoppers tend to skim past titles over 60.
- ClearNo sales or promo claimsNo sales-rank or promo terms.
What I plan to change
Planned, not yet applied. Before-and-after results are coming soon.
- Description · openingReplace the four opening questions with one plain, specific hook about what the reader will be able to do. Readers see only the first lines before "Read more."
- Description · credibilityMove "criminal defense investigator and police expert" into the first paragraph. Right now it's buried in paragraph two.
- Description · structureAdd a short list of what's inside (report types covered, what to look for), formatted with KDP-supported HTML.
- Description · seriesIt says "a first in the series." Link the next lesson if it exists, or soften the line if it doesn't yet.
- Keywords & categoriesReview the 7 keyword boxes and categories. They aren't visible on the public page, so they need to be pulled from the publishing dashboard. The book is distributed through PublishDrive, so changes may need to go through PublishDrive rather than KDP directly.
How we'll measure it
- Log Best Sellers Rank once a day for 14 days with no changes (baseline).
- Change one thing, the description, then log daily for another 14–30 days.
- Then keywords, then categories, one at a time, so we can tell what did what.
- Publish the before/after text, the daily log and, if I'm comfortable sharing them, the sales numbers from the distributor report. If nothing moves, that gets published too.
Rank alone can't prove cause and effect: ads, seasons and promotions move it too. We'll note anything else that changed during each window.
