1. URL Structure & Stability Rules
URLs across the network follow a predictable, minimalist rule set:
- Use short, descriptive slugs (e.g.,
/privacy.html,/acne-scars.html). - No unnecessary folders unless a topic has 5+ subpages.
- Use hyphens, never underscores.
- Never change a URL unless absolutely necessary.
- Redirects must always be 301 and permanent when restructuring.
This ensures that search engines never lose context and deep links from other domains never break.
2. Cross-Site Linking Patterns
Every educational site links upward to:
- a comparison hub (e.g., AcneHeals.com)
- governance domains (Disclosure.bio, Terms.bio, etc.)
Every comparison site links downward to:
- its matching ingredient or education domain
- the global policy network
This creates a clean “hub → spoke → hub” cycle for both SEO and UX.
3. Naming Conventions Across the Network
All ingredient-based education sites follow a consistent naming theme:
- Retinol.bio
- Niacinamide.bio
- Hyaluronic.bio
- Acne.bio
And each has a corresponding comparison domain (e.g., Retynol.com, Niacinimide.com, Hylaronic.com, AcneHeals.com).
4. Standard Content Layout
Ingredient/education pages follow this mandatory order:
- Hero intro (purpose + scope)
- 101 section
- How it works
- Routine or usage
- Mistakes / warnings
- FAQ
- CTA to comparison hub
Comparison pages follow a similar but product-focused structure with tables, routines, FAQ, and disclaimers.
5. Internal Indexing Rules
Each domain must include:
- a clear site-header with nav anchors or cross-links
- a consistent breadcrumb model (optional, only if 5+ subpages)
- a footer that connects to all governance domains
- a canonical URL matching the root domain
All pages must be linkable, indexable and crawl-friendly.
6. Where Indexing.bio Fits in the Framework
Indexing.bio is the “map” of the network, defining:
- site hierarchy
- interlinking logic
- file structure expectations
- how governance pages sit above all properties
It is the architectural layer powering consistency across ~40+ domains.
