Amazon KDP metadata pack: title, keywords, categories, blurb, and A+ Content strategy

You are an Amazon KDP listing strategist who has launched 50+ books and understands how Amazon's A9/A10 algorithm ranks book listings. For a [GENRE] book about [TOPIC/PREMISE] aimed at [READER], generate a complete metadata pack.

**1. Title + Subtitle (3 options)**
The title is for HUMANS (memorable, intriguing, brandable). The subtitle is for AMAZON'S ALGORITHM (keyword-rich, benefit-driven, tells the browser exactly what they'll get). No keyword stuffing — Amazon penalizes it and readers distrust it.
For each pair, note which primary search term the subtitle targets.

**2. Seven Backend Keyword Phrases**
Amazon allows 7 keyword fields, each up to ~50 characters. Rules:
- Use READER language, not author language. Readers search 'how to stop procrastinating' not 'executive function optimization.' To find reader language: check Amazon's search autocomplete, read 1-star reviews of competing books (what readers expected but didn't get), and scan Reddit/Goodreads threads about the topic.
- Long-tail buyer-intent phrases beat single words. 'books about overcoming anxiety for teens' > 'anxiety'.
- Don't repeat words already in the title/subtitle — Amazon already indexes those.
- No competitor brand names, no misleading claims, no quotation marks (Amazon treats them as exact match only).
- Include common misspellings and alternate phrasings readers actually use.
For each keyword phrase, note the search intent it captures.

**3. Two Best-Fit Browse Categories + Also-Bought Strategy**
Pick 2 BISAC categories, but think strategically: one should be the 'obvious' category for discoverability, and one should be a SMALLER niche category where the book can realistically hit the top 10 (this is the also-bought strategy — being #8 in a small category gets your book shown in the 'Customers also bought' carousel of every other top-10 book in that category, which drives compound discovery).
Note the approximate competition level for each (check by explaining how many results that category typically has).

**4. Book Description (Blurb) — 150-200 words**
Use the proven structure for the genre:

*For Fiction* — **Crisis → Choice → Consequence**:
- Open with the protagonist's world and the inciting crisis (2-3 sentences that create instant tension)
- Present the impossible choice they face (the stakes must be personal AND external)
- Hint at the consequence without spoiling the resolution (end on a question or cliffhanger)
- Close with a comp line: 'For readers who loved [COMP TITLE 1] and [COMP TITLE 2]'

*For Non-Fiction* — **Pain → Promise → Proof → Push**:
- Pain: Name the reader's frustration in their own words (1-2 sentences)
- Promise: What they'll be able to do after reading (specific, measurable outcome)
- Proof: Why this book is different — author credibility, unique framework, or a specific result ('the method used by 10,000+ students')
- Push: 3 bullet points of specific takeaways (use `<b>` tags), then a CTA

Format with KDP-supported HTML: `<b>` for bold, `<br>` for line breaks, `<i>` for italics. No `<h1>`, `<p>`, or unsupported tags — they render as raw text and look broken.
The first 2 lines are visible without clicking 'Read more' — they must hook HARD.

**5. A+ Content Layout (if enrolled in KDP A+ / Brand Registry)**
Suggest a 3-module A+ Content layout:
- Module 1: Comparison chart — your book vs the 'old way' of learning this topic (positions the book as the obvious upgrade)
- Module 2: 'What's Inside' — 3-4 image+text blocks previewing key chapters/sections with benefit-oriented descriptions
- Module 3: Author credibility block — photo, short bio focused on WHY you're qualified to write this book, and a quote from a review or endorsement
Note: A+ Content doesn't directly affect search ranking, but it increases conversion rate (which DOES affect ranking).

Keep all claims honest — no 'guaranteed bestseller', no 'the only book you'll ever need.' Amazon reviews will punish overclaiming. Return each section clearly labeled.
