URL Hierarchy

What is URL Hierarchy?

URL hierarchy describes the logical structure and organization of URLs on a website. It reflects the content organization and helps both users and search engines understand and navigate the website.

A well-thought-out URL hierarchy is a fundamental part of technical SEO and directly influences:

• Crawl Efficiency of search engines
• User-Friendliness and navigation
• Link Authority Distribution between pages
• Content Discovery and findability

Principles of URL Hierarchy

1. Logical Structure

URLs should reflect the content hierarchy of the website:

https://example.com/
├── /category/
│   ├── /subcategory/
│   │   └── /article/
│   └── /other-article/
├── /blog/
│   ├── /2024/
│   │   └── /article-name/
│   └── /2023/
└── /contact/

2. Consider Click Level

Important pages should not be more than 3-4 clicks away from the homepage:

3. Create Content Clusters

Related content should be organized in thematic silos:

https://example.com/
├── /health/              # Health Silo
│   ├── /nutrition/
│   ├── /fitness/
│   └── /medicine/
├── /technology/          # Technology Silo
│   ├── /smartphones/
│   ├── /laptops/
│   └── /software/
└── /lifestyle/           # Lifestyle Silo
    ├── /fashion/
    ├── /beauty/
    └── /travel/

URL Hierarchy Types

1. Flat Hierarchy (Flat Architecture)

Characteristics:

• All pages maximum 2-3 clicks from homepage
• Short, direct URLs
• Simple navigation

Advantages:

• Better crawl efficiency
• Higher link equity distribution
• Simpler navigation

Disadvantages:

• Limited scalability
• Less thematic grouping

Example:

https://blog.com/
├── /article-1/
├── /article-2/
├── /article-3/
└── /article-4/

2. Deep Hierarchy (Deep Architecture)

Characteristics:

• Multiple nesting levels
• Detailed categorization
• Long URL paths

Advantages:

• Detailed organization
• Better thematic grouping
• Scalable for large websites

Disadvantages:

• Higher click depth
• More complex navigation
• Potential crawl problems

Example:

https://shop.com/
├── /category/
│   ├── /subcategory/
│   │   ├── /product-group/
│   │   │   └── /individual-product/
│   │   └── /other-group/
│   └── /other-subcategory/
└── /other-category/

3. Hybrid Hierarchy

Characteristics:

• Combination of flat and deep structures
• Important pages flat, detail pages deeper
• Flexible organization

Advantages:

• Optimal balance between usability and organization
• SEO-friendly
• Scalable

Example:

https://magazine.com/
├── /categories/          # Flat for main categories
│   ├── /sports/
│   ├── /politics/
│   └── /economy/
├── /sports/              # Deep for detail organization
│   ├── /football/
│   │   ├── /premier-league/
│   │   └── /champions-league/
│   └── /tennis/
└── /archive/             # Flat for archive
    ├── /2024/
    └── /2023/

Best Practices for URL Hierarchy

1. Consistent Structure

DO:

• Use uniform URL patterns
• Maintain logical categorization
• Predictable URL structure

DON'T:

• Mixed URL formats
• Inconsistent nesting
• Arbitrary categorization

2. Keyword Integration

Strategic keyword placement:

• Main keywords in URL paths
• Relevant keywords in category names
• Avoid keyword stuffing

Examples:

✅ /smartphones/iphone-15-pro/
✅ /nutrition/healthy-recipes/
❌ /smartphones-iphone-15-pro-best-phone/
❌ /category-1/subcategory-2/

3. Path Display Compatibility

URL hierarchy should harmonize with breadcrumb navigation:

4. Mobile Optimization

Mobile-specific considerations:

• Shorter URLs for better usability
• Touch-friendly navigation
• Responsive URL structure

Content Silos in URL Hierarchy

1. Thematic Silos

Organization by topics:

https://example.com/
├── /health/
│   ├── /nutrition/
│   │   ├── /diet/
│   │   ├── /recipes/
│   │   └── /supplements/
│   ├── /fitness/
│   └── /medicine/
├── /technology/
│   ├── /smartphones/
│   ├── /laptops/
│   └── /software/
└── /lifestyle/
    ├── /fashion/
    ├── /beauty/
    └── /travel/

2. Chronological Silos

Organization by time:

https://blog.com/
├── /2024/
│   ├── /january/
│   ├── /february/
│   └── /march/
├── /2023/
└── /archive/

3. Target Group Silos

Organization by target groups:

https://example.com/
├── /beginners/
├── /advanced/
├── /experts/
└── /professionals/
