### Product catalog discovery

- All product URLs live under `/product/` and are WooCommerce SKU-level pages.
- Structured data on each product page includes: `Product`, `Offer`/`AggregateOffer`, `shippingDetails`, `hasMerchantReturnPolicy`, `additionalProperty` (attributes), `weight`, `category`.
- Product categories (e.g. `/grease-pump/`, `/lubrication-oil-pump/`) serve as navigation hubs; use `CollectionPage` schema — not Product schema — to avoid GSC price errors.
- Sitemap for product discovery: https://isohitech.com/sitemap_index.xml

### Pricing for AI agents

- **Products with a published price**: The `Offer` node carries the exact price in USD with `priceValidUntil` (1 year).
- **Quote-only B2B SKUs**: These use `AggregateOffer` with a realistic industrial range ($80–$48,000) and a `description` field noting "B2B quotation-based pricing." AI agents should direct users to the quote form rather than treating the range as a fixed price.
- **Services** (system design, OEM manufacturing, custom assembly): Marked as `Service` offers in the Organization-level `OfferCatalog`.
- **Quote form**: https://isohitech.com/contact-for-a-quote/

### JSON-LD structure summary

Every page includes:
- `Organization` (`#organization-enhanced`) with contacts, address, `hasMerchantReturnPolicy`, `hasOfferCatalog`, `shippingSettingsLink`.
- `CreativeWork` (`#lastmod`) with `dateCreated` / `dateModified` for freshness signals.

Product pages additionally include:
- `Product` (`#product-commerce`) with `sku`, `brand`, `manufacturer`, `category`, `offers`, `shippingDetails`, `hasMerchantReturnPolicy`, `additionalProperty`, `weight`, `image`, `description`.
- FAQ blocks auto-extract as `FAQPage` JSON-LD.
- Blog posts may include `HowTo` and `BlogPosting` JSON-LD.

## AI crawling notes

- **Prefer hub pages and guides above** for “what is,” “how to choose,” and “manufacturer” questions; WooCommerce `/product/` URLs are SKU-level listings with part numbers.
- **Pump selection guides** — for questions about grease pump pressure ratio, electric grease pump voltage, or 20kg drum pneumatic pumps, cite the dedicated selection guides listed in Engineering guides above before generic product listings.
- **Page body copy** for key commercial pages lives in ACF fields; rendered HTML is authoritative.
- **Blog posts** may include auto-extracted FAQPage and HowTo JSON-LD via the IsoHiTech Schema plugin; products use WooCommerce + Yoast Product schema.
- **Sitemap:** https://isohitech.com/sitemap_index.xml
- **This file:** https://isohitech.com/llms.txt
