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.

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.

H2
Gaming Laptops, Business Laptops
Thematic Structure
3-5x
H3
Graphics Card, Processor, RAM

Silo Structure

The silo structure organizes related content into thematic groups:

Example: Fitness Website

  • Silo 1: Training
    • Strength Training
