Marketplace Listing Optimizer

Q: How do I know the Marketplace Listing Optimizer output is good?

The skill verifies itself against its own 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.

Audit and optimize a marketplace listing (Amazon, Etsy, eBay, Walmart) to rank and convert. Use when asked to optimize an Amazon/Etsy listing, improve marketplace SEO, fix a product listing that isn't selling, or write keyword-rich titles and bullets. Produces a prioritised optimization — title, bullets, backend keywords, A+/description, images plan, and conversion fixes — mapped to how that marketplace ranks and shoppers decide.

What to give it

▸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".

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓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

⚠️ What it refuses to do

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
