## Site Network Linking Strategy

### Internal links (内链 — same domain guoweichemistryco.com)
Use for navigation, product discovery, and corporate authority:
- Home → Products → individual product detail pages
- Product pages cross-link related chemicals (e.g. Soda Ash ↔ Sodium Bicarbonate)
- All pages link to About, Contact, News via header/footer
- Breadcrumb: Home > Products > [Product Name]

### External links (外链 — owned product portals, same company)
Dedicated product sites are NOT third-party affiliates. They are specialized portals operated by Shandong Guowei Chemical Co., Ltd.:
- Link from corporate product pages to the matching dedicated portal
- Link from corporate hub footer and Product Network section to all portals
- Product portals should link back to https://www.guoweichemistryco.com/ as corporate hub
- Do not apply nofollow to these owned-network links
