seo-ecommerce is agent-read markdown (skill) from fusengine/agents: Use when optimizing e-commerce SEO — product/category pages, faceted navigation, marketplace listings..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<objective>
Covers e-commerce-specific SEO: Product schema (offers/aggregateRating/review/brand) plus BreadcrumbList on product pages, category page structure (intro copy, H1, pagination canonicals), faceted-navigation indexing rules by filter-combo count, out-of-stock handling (keep the page, set availability, link to alternatives), internal search page blocking/optimization, and marketplace-specific tactics (Amazon A+ Content, Etsy tags, eBay item specifics). Schema templates live in `templates/json-ld/`.
</objective>
# E-commerce SEO
## Product Pages
- `Product` schema with `offers`, `aggregateRating`, `review`, `brand`
- `BreadcrumbList` schema
- Unique meta title/description per product
- Canonical to self (not category)
- Reviews above the fold (with schema)
- Out-of-stock: keep page, set `availability: OutOfStock`, link to alternatives
## Category Pages
- Intro paragraph 150-300 words (above products)
- H1 with category keyword
- Pagination: `rel="canonical"` on each paginated page (Google deprecated rel=next/prev)
- Filter URLs: see Faceted Navigation below
## Faceted Navigation Rules
| Filter combo | Action |
|--------------|--------|
