# Marketplace Listing Optimizer Skill

On a marketplace, the listing *is* the salesperson — and the algorithm reads it before a human does. Ranking
comes from relevance (the right keywords in the right fields) and performance (click-through and conversion).
This skill audits a listing against both and returns prioritised fixes, so "it's buried and not converting"
becomes a specific to-do list.

## Working from a brief

Given a product and maybe a current title, **produce the full optimization anyway** — infer the category,
buyer, and likely keywords, and label inferences. Don't invent metrics, certifications, or claims. Never
withhold the audit for missing detail; mark what to confirm.

## Required Inputs

Ask for these only if they aren't already provided (else infer and label):

- **The marketplace & category** — Amazon, Etsy, eBay, Walmart… and the product category.
- **The product & current listing** — what it is, key attributes, and the current title/bullets if any.
- **The buyer & search terms** — who buys it and the terms they'd search (or let the skill propose them).
- **Known issues** — low traffic, low conversion, bad reviews, or just "make it better".

## Output Format

### Listing Optimization: [product] on [marketplace]

**1. Diagnosis** — is the gap *visibility* (keywords/relevance) or *conversion* (title/images/price/reviews)? Lead with the bigger lever.

**2. Keywords** — primary, secondary, and long-tail terms, grouped, and where each belongs (title vs. bullets vs. backend/tags). Note any to confirm with real search-volume data.

**3. Title** — an optimized title following the marketplace's pattern and length limit (Amazon: brand + key features + size/qty; Etsy: front-load buyer phrases).

**4. Bullets / key features** — rewritten benefit-led bullets that also carry secondary keywords.

**5. Description / A+** — the longer copy (Amazon A+ modules, Etsy description) — structure + key points.

**6. Backend / tags** — hidden keyword fields, tags, attributes to fill (no repeats of the title).

**7. Images & media plan** — the shot list that converts (main on white, infographic, lifestyle, scale, detail) — a checklist, not the images.

**8. Conversion fixes** — price/coupon, reviews strategy, A+ trust, and anything dragging the buy decision.

**9. Prioritised actions** — ordered by impact-to-effort.

## Quality Checks

- [ ] The diagnosis distinguishes a visibility problem from a conversion problem and leads with the bigger one
- [ ] Keywords are placed in the fields that actually rank on that marketplace (title/bullets/backend)
- [ ] Title follows the marketplace's convention and character limit
- [ ] No keyword is wastefully repeated across title and backend fields
- [ ] Bullets are benefit-led, not a spec dump
- [ ] Actions are prioritised by impact; invented data/claims are flagged to confirm

## Anti-Patterns

- [ ] Do not stuff the title with every keyword — relevance + readability beat a keyword soup the algorithm discounts
- [ ] Do not repeat title keywords in the backend field — it wastes indexable space
- [ ] Do not optimize keywords while ignoring conversion (images, reviews, price) — ranking without conversion decays
- [ ] Do not invent search volume or claims — flag them to verify with the marketplace's tools
- [ ] Do not give a flat list — rank fixes so the seller knows what to do first
