Website Navigation and Information Architecture Guide

By Grocito14 October 2026

Information architecture is the way a website's content is organised, labelled and linked so people can find what they need without thinking about it. Good website navigation starts with the tasks visitors come to do, groups pages in the way they expect, uses plain menu labels, keeps the hierarchy shallow, and links related pages together. Test the structure with real users before and after launch.

Key takeaways

Information architecture is the structure underneath the pages; navigation is the visible part of it, such as menus, breadcrumbs and links.
Start from visitor tasks, not from your org chart. Groupings that mirror your internal teams rarely match how customers think.
Plain labels beat clever ones. A visitor should predict what sits behind a menu item before clicking it.
Strong internal linking and hub pages help people and search engines understand which pages belong together.
Test with simple methods such as tree testing and first-click tests, then keep a list of pages that no menu or link reaches.

What is information architecture, and why does it matter?

Think of a large shop: the shelves and layout are the information architecture, and the aisle signs are the navigation. Visitors arrive with a goal, such as finding a price, booking a call, checking a return policy or comparing two services. Every extra click, vague label or dead end costs patience. Structure also matters for search engines: as far as is publicly documented, crawlers discover pages by following links, so a clear structure helps important pages get found and understood in context.

How do you find the top tasks visitors care about?

Before drawing any menu, list the jobs your site must do. A practical method:

Collect questions. Pull the most common questions from sales calls, support emails, chat transcripts and search queries typed into your own site search.
List the top tasks. Write them as verbs: compare plans, book a demo, track an order, download a brochure, read the warranty.
Rank them. A short list of frequent tasks usually matters far more than a long tail of rare ones. Give the top handful the most prominent places in your navigation.
Check against the business goal. Some tasks matter to you even if visitors rarely ask about them, such as requesting a quote. Make those easy to find as well.

Card sorting in simple terms

Card sorting asks people to group page titles written on cards into piles that make sense to them and to name each pile. In an open sort, they invent the group names; in a closed sort, you give the group names and they place cards under them. It is cheap, and it quickly exposes your own insider vocabulary.

How do you build a sitemap and content hierarchy?

A sitemap is a diagram of your pages and how they nest. Build one before design starts.

Inventory what exists. If this is a redesign, export every current URL with its traffic and its purpose. Our guide on website redesign without losing SEO explains why this step protects existing visibility.
Group by task or topic. Put pages that answer the same need together.
Keep depth shallow. Aim for important pages being a few clicks from the home page. Deep nesting hides content, and very wide menus overwhelm people. Balance the two.
Give each page one job. If a page tries to serve three different tasks, split it.
Name the hubs. Each major section needs a landing page that introduces the topic and links to the detail pages below it.

How should you design menus: labels, depth, mega menus and mobile?

Labels

Use the words visitors use. "Pricing" beats "Investment options"; "Contact" beats "Let's connect". Avoid labels that could mean several things, such as "Solutions" or "Resources", unless the dropdown beneath makes the meaning obvious. Keep the same label for the same page everywhere.

Depth and number of items

A primary menu with a handful of well-chosen items is easier to scan than a long list. Beyond one level of dropdown, usability tends to drop, especially on touch screens. If you need more, use a landing page that lists the options instead of a deeper menu.

Mega menus

Mega menus can suit large sites such as stores or services with many offerings, because they show a grouped overview at once. Make them keyboard-accessible, avoid hover-only behaviour, group items under clear headings, and do not stuff them with every page you own. If your top-level categories fit a simple dropdown, use that.

Mobile navigation

On phones, the menu usually collapses behind an icon. Label the icon clearly, make tap targets generous, put search within reach, and keep the most important action, such as call or book, visible outside the menu. Test with one thumb on a real device. Our guide on responsive design covers related layout choices.

What makes good URLs and breadcrumbs?

URLs should be readable, short and consistent: a lowercase path that mirrors the hierarchy, such as a services section followed by the specific service. Once pages are live, change URLs only with a good reason and redirect the old ones.

Breadcrumbs show the path back up the hierarchy and help visitors who land deep in the site from a search result. They work best on sites with real depth, such as catalogues, documentation and long service lists. They complement the main menu rather than replacing it.

Internal linking, hub pages and topic clusters

Menus cannot hold everything. Links inside content connect related pages and tell readers where to go next.

Hub and spoke: A hub page covers a broad topic and links to detailed pages; each detailed page links back to the hub and to its close siblings. This is often called a topic cluster.
Descriptive anchor text: Link text such as "compare our service plans" is better than "click here" for readers using screen readers and for search engines.
Link where it helps: Add links at the moment a reader might ask the next question, not in bulk at the end.
Review orphan pages: An orphan page is one that no other page links to. Crawl your site, compare the result with your sitemap and published pages, and either link the orphans in or retire them.

Our on-page SEO checklist shows how headings and links work together on each page.

Search, filters, footers and utility links

Site search

On content-heavy sites and stores, a visible search box is part of navigation. Review searches that return nothing; they show missing content and naming mismatches.

Filters and facets

Filters should reflect how people choose, such as size, price range or category, and show how many results remain. Be careful that filter combinations do not generate endless crawlable URLs with near-identical content; your developer or SEO specialist can manage this.

Footers and utility links

The footer is a reliable place for contact details, legal pages, careers, sitemap and secondary links. Keep utility links such as login, cart or language choice in a consistent spot.

How do you test navigation with tree tests and first-click tests?

You do not need a research lab.

Tree testing: Show participants a plain text outline of your menu, with no design, and ask them to find where they would go to complete a task, such as "find the returns policy". If many people pick the wrong branch, the labels or grouping need work.
First-click testing: Show a screenshot or prototype and ask where they would click first for a task. A wrong first click is a useful early warning that the label or placement is not working.

Run these before the build to save rework, and again after launch.

Common redesign pitfalls

Merging many pages into one without redirects, losing existing search visibility.
Forgetting accessibility: keyboard focus, visible focus states and screen reader labels. See our accessibility basics.

A worked example

Imagine a regional training company whose site has menus labelled Solutions, Resources, Company and Engage. Visitors keep phoning to ask about course dates. A top-task review shows people mainly want to browse courses, check dates, see prices and book. The team runs a card sort, renames the menu to Courses, Dates and Prices, About and Contact, builds a hub page for each course category, adds breadcrumbs and a search box, and links every course page back to its hub. A tree test before launch shows the revised labels are found more reliably. They then check for orphan pages.

FAQ

What is the difference between information architecture and navigation?

Information architecture is the underlying organisation of content: how pages are grouped, named and related. Navigation is the visible set of tools built on top of it, such as menus, breadcrumbs, search and links. You can redesign the menu without changing the architecture, but a weak architecture cannot be fixed by menu styling alone.

How many items should a website menu have?

There is no magic number. Choose the fewest items that cover your top visitor tasks and fit a clear grouping, usually a small set that can be scanned at a glance. If you need more, use a landing page or a well-structured mega menu rather than a long single list.

Does website structure affect SEO?

Yes, indirectly. As far as is publicly documented, search engines discover and understand pages through links, so a clear hierarchy, descriptive internal links and sensible URLs help important pages get found. A clean structure also makes visitors stay and complete tasks, which supports your business goals.

What is an orphan page and how do I find one?

An orphan page is a live page that no other page on your site links to, so visitors and crawlers rarely reach it. Crawl your site with an SEO tool, compare the list with your sitemap and CMS page list, then link the useful orphans from relevant pages or remove the rest.
