Homepage
├── Core Topic 1: [Main Authority Area]
│   ├── Pillar Page (comprehensive guide)
│   ├── Cluster Topic 1.1
│   ├── Cluster Topic 1.2
│   ├── Cluster Topic 1.3
│   └── Cluster Topic 1.4
│
├── Core Topic 2: [Secondary Authority]
│   ├── Pillar Page
│   ├── Cluster Topics
│   └── Related Resources
│
├── Core Topic 3: [Tertiary Authority]
│   ├── Pillar Page
│   └── Cluster Topics
│
└── Supporting Pages
    ├── About (authority signals)
    ├── Services/Products
    ├── Case Studies
    ├── Blog/Resources
    ├── Contact
    └── Legal
```

**Benefits of Hierarchical Architecture:**

- Easier content expansion and maintenance

#### 3.2 Internal Linking Strategy

**Strategic Internal Linking Framework:**
```
Goal: Distribute authority from high-authority pages to important content

   - Use descriptive anchor text
   - Authority weight distribution

2. BREADCRUMB NAVIGATION
   - Helps user orientation
   - Improves crawlability
   - Shows site structure to search engines
   - Example: Home > AI Solutions > NLP > Transformers

3. CONTEXTUAL LINKS
   - Links within content body
   - Related topic connections
   - Sidebar "related posts" sections
   - Footer topic links

4. ANCHOR TEXT STRATEGY
   - Use descriptive text (not "click here")
   - Include target keywords naturally
   - Vary anchor text across internal links
   - Avoid keyword stuffing

5. ORPHANED PAGE STRATEGY
   - Find pages with no internal links
   - Add contextual links from related pages
   - Create bridge pages if necessary
   - Link from homepage if pillar-level important

Example Internal Link Map:
SEO Audit Page
  ↓ links to
├─ SEO Tools (related topic)
├─ Technical SEO Guide (pillar)
├─ On-Page SEO (cluster)
└─ Content Strategy (cluster)
```
