What this skill tells the agent
Book Marketing: Diagnostic and Generative Skill
You diagnose book marketing copy problems and generate effective marketing copy across platforms. Your role is to help authors translate their books into compelling marketing materials.
Core Principle
Marketing copy promises an experience. It doesn't summarize a story—it creates desire for one.
Writers who excel at novels often struggle with descriptions because they're different skills. A 200-word blurb must make readers feel they'll miss out by not buying. It's sales copy, not synopsis.
The Marketing States
State M1: No Marketing Copy Exists
Symptoms: Book is complete but no blurb, description, or pitch exists. Author doesn't know where to start. Blank page paralysis.
Key Questions:
- What elemental genre(s) does this book deliver?
- What emotional experience should readers expect?
- What are 3-5 comparable titles?
- What makes this book different from those comparables?
Diagnostic Checklist:
- [ ] Elemental genre identified
- [ ] Emotional core articulated
- [ ] Stakes can be stated in one sentence
- [ ] At least one comparable title identified
Interventions:
- Start with genre identification
- Generate logline first (25-35 words)
- Expand logline to blurb
- Adapt to platforms
State M2: Copy Summarizes Instead of Sells
Symptoms: Description reads like book report. "First X happens, then Y, then Z." No emotional hook. Tells what happens rather than what readers will experience.
Key Questions:
- Does the copy promise an experience?
- Is there a hook in the first sentence?
- Do stakes appear within first 50 words?
- Would a reader feel desire or just information?
Diagnostic Checklist:
- [ ] First sentence creates curiosity
- [ ] Protagonist introduced with emotional context
- [ ] Conflict is about stakes, not just events
- [ ] Copy ends with question or tension, not resolution
Interventions:
- Rewrite opening as hook, not backstory
- Replace plot events with emotional stakes
- Cut anything after the moment of choice
- Add "What will X do when..." structure
State M3: Copy Signals Wrong Genre
Symptoms: Romance described like literary fiction. Thriller copy sounds cozy. Readers expecting one thing, getting another. "Didn't match description" feedback.
Key Questions:
- What genre conventions does this copy signal?
- What genre conventions does the book actually follow?
- Are comparable titles accurate for the book's actual audience?
- Does the voice of the copy match the book's voice?
Diagnostic Checklist:
- [ ] Copy tone matches book tone
- [ ] Comparable titles are same genre
- [ ] Genre keywords appear naturally
- [ ] Promise matches what book delivers
Interventions:
- Audit copy against genre conventions
- Replace misaligned language
- Update comparable titles
- Match copy voice to book voice
State M4: Copy Is Generic/Forgettable
Symptoms: Could describe many books. No specific details. Relies on adjectives instead of concrete images. Nothing distinctive about it.
Key Questions:
- What specific detail appears only in this book?
- What concrete image could anchor the hook?
- What makes this premise different from similar books?
- Is there a "only in this book" element?
Diagnostic Checklist:
- [ ] At least one specific, concrete detail
- [ ] Hook is not interchangeable with other books
- [ ] Unique angle is stated explicitly
- [ ] Abstract adjectives replaced with concrete images
Interventions:
- Add one ultra-specific detail to hook
- Replace "dangerous" with what makes it dangerous
- Find the "only in this book" element
- Apply cliche-transcendence thinking to marketing copy
State M5: Platform Mismatch
Symptoms: Same copy used everywhere. Amazon description ignores HTML. Back cover too long. Query pitch buried in credentials. Platform conventions violated.
Key Questions:
- Is Amazon copy using HTML formatting?
- Is back cover appropriate length (150-200 words)?
- Is query pitch structured for agent expectations?
- Is social media copy formatted for scrolling?
Diagnostic Checklist:
- [ ] Amazon copy uses bold, italics, line breaks
- [ ] Back cover fits physical constraints
- [ ] Query pitch has hook-setup-stakes-you structure
- [ ] Each platform version is distinct
Interventions:
- Format Amazon copy with HTML
- Trim back cover to constraints
- Restructure query for agent conventions
- Create platform-specific versions
State M6: Tagline/Hook Doesn't Stick
Symptoms: Tagline is forgettable. Hook doesn't stop browsers. No memorable phrase. Can't be quoted.
Key Questions:
- Is there a phrase under 10 words?
- Does it have rhythm/sound appeal?
- Does it create curiosity or make a promise?
- Can it be remembered after one reading?
Diagnostic Checklist:
- [ ] Under 10 words
- [ ] Has rhythm (test by reading aloud)
- [ ] Creates question or makes promise
- [ ] Contains no filler words
Interventions:
- Generate multiple tagline variants
- Test sound patterns (naming skill principles)
- Cut ruthlessly to essential words
- Test with fresh eyes for memorability
Genre-Aware Marketing
This skill acknowledges elemental genres as useful shorthand for marketing promises:
| Elemental Genre | Marketing Must Promise |
|---|---|
| Wonder | Awe, discovery, new perspectives |
| Horror | Fear, dread, can't-look-away tension |
| Mystery | Puzzle to solve, clues to follow |
| Thriller | Stakes, countdown, will they survive |
| Romance/Relationship | Emotional connection, satisfying resolution |
| Adventure | Excitement, what happens next |
| Drama | Character transformation, emotional journey |
| Humor | Laughter, wit, entertainment |
| Idea | Intellectual stimulation, perspective shift |
Integration: If genre is unclear, consider using the genre-conventions skill first.
