Website Architecture and Structure

Website architecture describes how your pages are organized and how users and search engines move between them. A clear structure makes important content easier to discover and helps search engines understand the relationship between different sections of your website.

A strong architecture should make it obvious where a page belongs, what topics are related and which pages are most important to your business.

A Simple Website Hierarchy

A typical website might follow a structure such as: Homepage → Category → Subcategory → Individual Page. The exact structure depends on the size and purpose of the website, but the important pages should remain easy to reach.

Important Architecture Principles

Logical Hierarchy

Organize pages into logical groups that make sense to both visitors and search engines.

Clear Internal Links

Important pages should have useful internal links pointing to them from relevant content.

Avoid Orphan Pages

Important pages should not be isolated from the rest of your website.

Manage Page Depth

Avoid making important content unnecessarily difficult to reach through multiple layers of navigation.

Use Descriptive Categories

Category and section names should clearly communicate the topic of the content they contain.

Keep Navigation Consistent

Users should be able to predict where they can find important information throughout the website.

Good vs Poor Architecture

Stronger StructurePotential Problem
Clear category hierarchyRandom collection of unrelated pages
Important pages linked from relevant contentImportant pages with few or no internal links
Descriptive navigation labelsGeneric labels such as 'Click Here'
Logical URL hierarchyUnclear or inconsistent URL patterns
Consistent navigationDifferent navigation structures across pages

Orphan Pages

An orphan page is a page that has little or no internal linking from other pages on the website. If an important page is not connected to the site's navigation or contextual internal links, both users and crawlers may have difficulty discovering it.

💡

SEOHACK Tip

When auditing site architecture, identify important pages that receive very few internal links. Strengthen their connection to relevant category pages, navigation elements and related content rather than relying on the XML sitemap alone.
