Information Architecture
Information Architecture (IA) is the structural design of information spaces that enables users to find and understand content intuitively. In the SEO context, this means organizing a website so that both search engines and users can navigate optimally.
IA vs. UX vs. SEO Comparison
The 8 Fundamental Principles of Information Architecture
001. Object Principle
Every content should be considered as an independent object with clear properties and relationships.
002. Choice Principle
Less is more - limit the number of options to avoid decision fatigue.
003. Disclosure Principle
Important functions and content must be immediately recognizable.
004. Example Principle
Use concrete examples to illustrate abstract concepts.
005. Front Door Principle
Not all users come through the homepage - every page must function as an entry point.
006. Multiple Classification Principle
Offer different ways to find the same content.
007. Focus Principle
Every page should have a clear focus and a defined goal.
008. Growth Principle
The structure must be scalable and expandable.
Content Hierarchy for SEO
Content hierarchy forms the backbone of an SEO-optimized website. It determines how search engines evaluate the relevance and importance of content.
H1-H6 Hierarchy
Silo Structure
The silo structure organizes related content into thematic groups:
Example: Fitness Website

- Strength Training
- Cardio
- Flexibility
- Silo 2: Nutrition
- Macronutrients
- Micronutrients
- Supplements
- Silo 3: Equipment
- Weights
- Cardio Equipment
- Accessories
