How to Plan Website Information Architecture for SEO

What Is Website Information Architecture?

Information architecture is the organisation and relationship of information within a website.

For SEO, this includes decisions about:

• Which pages should exist.
• What purpose each page should serve.
• How pages should be grouped.
• Which pages should act as hubs.
• Which pages should be subordinate to other pages.
• How topics should relate.
• How users should navigate between pages.
• How internal links should reinforce those relationships.
• How URLs should reflect the structure where useful.
• How search queries should map to appropriate destinations.

The result should be a website that is understandable as a system rather than a collection of unrelated URLs.

Start With the Website’s Purpose

Do not begin by drawing boxes in a sitemap.

First determine:

• What does the organisation do?
• Who does it serve?
• What does the website need users to accomplish?
• Which products, services or subjects matter most?
• Which information supports those areas?
• Which search audiences are relevant?
• Which existing pages already perform useful functions?

Architecture should support the website’s actual purpose.

Search demand is important, but keyword volume alone should not dictate the structure of a business.

Inventory the Existing Website

For an established website, begin with what already exists.

Create an inventory containing useful fields such as:

• URL.
• Page title.
• H1.
• Content type.
• Current section.
• Indexability.
• Canonical URL.
• Status code.
• Organic clicks.
• Impressions.
• Search queries.
• Internal links.
• Crawl depth.
• Sitemap inclusion.
• Proposed purpose.
• Proposed action.

The exact fields depend on the project.

The purpose is to create a reliable view of the current website before proposing a new one.

Identify the Main Topics

Determine the principal subjects the website needs to represent.

These are not automatically the keywords with the highest search volume.

They should reflect the intersection of:

• Business relevance.
• User needs.
• Search demand.
• Existing expertise.
• Products or services.
• Content requirements.
• Search intent.

A topic can then contain narrower subtopics where those distinctions genuinely serve users and search intent.

Understand Search Intent

Search intent helps determine what kind of page should satisfy a query.

Common patterns include:

• Informational.
• Commercial investigation.
• Transactional.
• Navigational.

These categories are useful, but real search behaviour is often more nuanced.

Examine the actual query and the type of information the searcher appears to need.

For example, someone searching for a service may need a commercial service page.

Someone searching how that service works may need an educational guide.

Those pages can cover related terminology while serving different purposes.

That distinction is fundamental to good architecture.

Map Queries to Pages

Once important search intents are understood, map query groups to the pages intended to satisfy them.

The objective is not:

One keyword = one page.

Instead:

Related queries with substantially the same intent and information need → one appropriate page.

This helps prevent unnecessary page creation.

A query-to-page map can contain:

• Query or query group.
• Intent.
• Topic.
• Existing ranking URL.
• Intended URL.
• Page type.
• Current performance.
• Overlap with other URLs.
• Recommended action.

This becomes particularly useful when validating possible cannibalisation.

Define Page Purpose

Every important page should have a defensible reason to exist.

A useful page-purpose statement answers:

What specific job does this URL perform that another URL does not?

For example:

Service page: explains a service and supports commercial evaluation.

Guide: teaches the subject in depth.

Project: demonstrates actual work.

Case Study: documents a problem-solving process and its outcome.

These pages may discuss the same discipline without being duplicates because their purposes differ.

If you cannot clearly explain why two pages need to exist separately, investigate whether consolidation is appropriate.

Build the Hierarchy

Once page purposes are understood, organise them into a logical hierarchy.

A simple model might be:

Home
|
+-- Services
|   +-- Service A
|   +-- Service B
|
+-- Products
|   +-- Product A
|   +-- Product B
|
+-- Resources
|   +-- Guide A
|   +-- Guide B
|
+-- About
+-- Contact

Hierarchy should communicate relationships.

It should not be created merely to make URLs look organised.

Identify Hub Pages

A hub page represents a meaningful subject or section and helps users discover related material.

A strong hub should normally have its own purpose.

It should not exist only as a list of links unless that is genuinely the most useful experience.

For example, a Services hub can explain the overall service model before directing visitors to individual services.

A Resources hub can organise educational material and help visitors discover relevant guides.

Hubs are particularly useful when a topic or section contains several meaningful child pages.

Avoid Creating a Page for Every Keyword

Keyword research can easily produce hundreds or thousands of terms.

That does not mean the website needs hundreds or thousands of pages.

Before creating a separate URL, ask:

• Is the search intent different?
• Is the information need different?
• Does the page require substantially different content?
• Does it serve a distinct business or user purpose?
• Would combining it with another page produce a better resource?

If the answers are mostly no, a separate page may not be justified.

Design Navigation Around User Tasks

Primary navigation should expose the website’s most important destinations.

It should not attempt to expose every page.

Ask:

• What do first-time visitors need?
• Which sections define the website?
• Which destinations are commercially or functionally important?
• Which labels will users understand?
• Which content belongs in secondary navigation instead?

Navigation labels should describe destinations clearly.

Avoid vague labels where a specific one would be more useful.

Use the Footer as a Separate Navigation Context

The footer does not need to duplicate the header exactly.

It can provide:

• Important service links.
• Secondary exploration paths.
• Contact information.
• Professional profiles.
• Legal information.

The question is not whether a link already exists elsewhere.

The question is whether it is useful in that navigation context.

Avoid turning the footer into a repository for every SEO-targeted page.

Plan URL Structure Carefully

URLs can communicate structure, but they should remain stable and manageable.

A useful structure might be:

/services/
/services/technical-seo/
/services/content-seo/
/resources/
/resources/technical-seo-audit/

This communicates relationships naturally.

However, do not change established URLs merely to create visually perfect folder structures.

URL migrations introduce risk.

Any structural benefit must justify the change.

Plan Internal Linking as Part of the Architecture

Internal linking should not be added as an afterthought.

Determine which pages should naturally connect.

A useful relationship might be:

Educational Guide → Related Service → Relevant Project → Case Study → Contact

This does not mean every visitor must follow that sequence.

It means the architecture supports discovery between related information.

Use Contextual Internal Links

Contextual links should appear where the destination genuinely helps the reader.

For example, a technical SEO guide discussing website hierarchy may link to a deeper information architecture resource.

A service page may link to a guide when a visitor wants a detailed explanation of the methodology.

Use anchor text that explains the destination.

Avoid adding links purely because a spreadsheet says a page needs more internal links.

Understand Crawl Depth

Crawl depth describes how many link steps separate a page from the crawl starting point.

It can help reveal structural problems, but there is no universal rule that every page must be within an arbitrary number of clicks.

Interpret depth in context.

Ask:

• Is the page important?
• Is it intentionally subordinate?
• Can users discover it logically?
• Is it linked from relevant hubs?
• Does its depth reflect the hierarchy or an architectural mistake?

A deep URL is an observation.

It becomes a problem only when the evidence supports that diagnosis.

Identify Orphan Pages

An orphan page has no discoverable internal link path within the crawl being analysed.

To identify candidates, compare crawl data with other URL sources such as:

• XML sitemaps.
• Google Search Console.
• Analytics.
• CMS exports.
• Backlink data where relevant.

Then investigate.

An orphan URL may be:

• An important page accidentally disconnected from the site.
• An obsolete page.
• A campaign URL.
• A utility page.
• A URL that should redirect.
• A page that should not be indexed.

Finding an orphan candidate is the beginning of the diagnosis, not the conclusion.

Analyse Topic Relationships

Related topics should connect logically without forcing everything into one artificial silo.

Consider:

• Parent and child relationships.
• Sibling topics.
• Supporting information.
• Commercial and informational relationships.
• Prerequisites.
• Comparisons.
• Related concepts.

Internal links can express these relationships even when URLs belong to different sections.

A useful website behaves more like a connected information system than a collection of isolated silos.

Evaluate Content Overlap

Similar content is not automatically a problem.

Two pages can discuss the same broad subject while serving different intents.

Investigate:

• Page purpose.
• Search intent.
• Query overlap.
• Ranking URLs.
• Content similarity.
• Search result behaviour.
• Internal linking.
• Historical performance.

Then decide whether the pages should:

• Remain separate.
• Become more differentiated.
• Be consolidated.
• Be redirected.
• Be repositioned.

Do not consolidate pages solely because an SEO tool reports semantic similarity.

Validate Cannibalisation With Evidence

Cannibalisation is often diagnosed too casually.

Two pages mentioning the same keyword does not prove they are competing in a harmful way.

Look for evidence such as:

• Multiple URLs repeatedly appearing for the same meaningful query group.
• Ranking URLs switching in ways that appear detrimental.
• Similar pages serving the same intent.
• Internal signals that fail to establish a preferred destination.
• Performance that suggests the site lacks a clear primary page.

Even then, investigate before acting.

Multiple URLs appearing for related queries can sometimes be appropriate.

The goal is not to force every keyword onto a single URL.

The goal is to give each meaningful search intent an appropriate destination.

Decide When to Consolidate Content

Consolidation may be appropriate when:

• Two pages serve essentially the same purpose.
• Search intent substantially overlaps.
• Neither page provides a necessary distinct function.
• Query data supports the overlap.
• Combining the material would create a more useful destination.

But consolidation should not be automatic.

Before merging pages, determine:

• Which URL should survive.
• Which content should be retained.
• Which internal links need updating.
• Whether redirects are required.
• Whether external links point to the removed URL.
• Whether the surviving page needs restructuring.
• How performance will be monitored afterwards.

Content consolidation is an architectural change, not simply a writing task.

Separate Architecture Problems From Content Problems

Sometimes the page is fine but positioned incorrectly.

Sometimes the architecture is fine but the content does not satisfy the intended purpose.

For example:

Architecture problem: two commercial pages have effectively the same purpose.

Content problem: a correctly positioned service page does not adequately explain the service.

Technical problem: the correct page exists but is accidentally canonicalised elsewhere.

The remedy depends on the diagnosis.

Do not solve every SEO problem by rewriting content.

Connect Information Architecture With Technical SEO

Information architecture determines how information should be organised.

Technical SEO helps ensure that architecture can be crawled, processed and indexed appropriately.

The two disciplines intersect through:

• Internal linking.
• Navigation.
• Crawl paths.
• Canonicalisation.
• Redirects.
• XML sitemaps.
• Indexation.
• URL management.

A technically crawlable website can still have poor information architecture.

Likewise, a logically designed architecture can fail if technical implementation prevents search systems from accessing it properly.

Connect Information Architecture With Content SEO

Content strategy determines what information should exist and how it should satisfy user and search needs.

Information architecture determines where that information belongs and how it relates to other information.

A useful sequence is:

Search Need → Content Requirement → Page Purpose → Website Position → Internal Relationships

This prevents content production from becoming disconnected from the website structure.

Information Architecture for AEO

Answer-driven search depends on systems being able to identify relevant information efficiently.

Clear architecture can support this by making relationships between:

• Topics.
• Questions.
• Answers.
• Entities.
• Supporting information.

easier to understand.

Architecture alone does not guarantee selection in an answer system.

It creates a clearer information environment from which useful content can be discovered and interpreted.

Information Architecture for GEO

Generative search systems may synthesise information from multiple sources and pages.

Clear topic organisation, entity relationships, evidence and supporting content can help create a more coherent representation of a website’s subject matter.

Again, architecture does not guarantee citation or inclusion in generated responses.

It provides part of the foundation that makes information easier to interpret and contextualise.

Create an Architecture Map

Document the proposed structure before implementing major changes.

A useful architecture map can show:

• Level 1 pages.
• Child pages.
• Hubs.
• Supporting resources.
• Commercial pages.
• Informational pages.
• Navigation relationships.
• Important contextual links.

For larger websites, use a spreadsheet or visual diagram rather than trying to represent everything in a single tree.

Create a Page Specification Matrix

For important URLs, document:

• URL.
• Parent.
• Page type.
• Primary topic.
• Search intent.
• Page purpose.
• Primary query group.
• Navigation placement.
• Internal link relationships.
• Indexation intent.
• Canonical intent.
• Schema type where appropriate.
• CTA.
• Overlap boundary.

This becomes a useful source of truth for SEO, content and development work.

Prioritise Architectural Changes

Not every architectural imperfection requires a migration.

Evaluate changes based on:

Evidence: Is there a demonstrated problem?

Impact: What could improve?

Business relevance: Which important pages are affected?

Scale: How much of the website is involved?

Effort: What does implementation require?

Risk: Could URLs, rankings or user journeys be disrupted?

Dependencies: What must happen before the change?

Architecture changes can affect many pages simultaneously.

The larger the change, the stronger the justification should be.

Validate the New Architecture

After implementation, check whether the intended structure actually exists.

Validate:

• Navigation.
• Internal links.
• Redirects.
• Canonicals.
• Status codes.
• XML sitemaps.
• Robots directives.
• Breadcrumbs.
• Indexability.
• Crawl depth.
• Orphan pages.
• Search Console behaviour.

A diagram is not the architecture.

The implemented website is the architecture.

Measure After Structural Changes

Monitor relevant signals after significant architecture changes.

Depending on the project, this may include:

• Indexation.
• Organic clicks.
• Impressions.
• Ranking URLs.
• Query-to-page alignment.
• Internal crawl depth.
• Search landing pages.
• Crawl errors.
• Redirect behaviour.

Do not automatically attribute every subsequent ranking movement to the architecture change.

Search demand, competitors, algorithm changes, content changes and other factors can influence performance.

Good Information Architecture Is Not About Making a Perfect Tree

Websites are not filing cabinets.

Users may arrive through search, external links, navigation, internal links or direct URLs.

The architecture therefore needs both hierarchy and meaningful connections between related information.

The objective is not to force every page into a rigid silo.

It is to create a website where users and search systems can understand:

What information exists.

Where it belongs.

Why each page exists.

How pages relate.

Which destinations matter.

When those questions have clear answers, information architecture becomes part of the website’s SEO foundation rather than simply an exercise in organising menus.
