What is information architecture?

Information architecture (IA) is the way a website’s content is organized, grouped, labeled and linked, so visitors can find what they need and search engines can understand how pages relate to each other.

Also called IA, site structure

What it covers

  • Structure: which pages exist and how they are grouped, often drawn as a sitemap diagram
  • Navigation: the main menu, footer, breadcrumbs and links between pages
  • Labels: the words used for menu items and page names
  • URLs: paths that reflect the structure, such as /services/website-migration
  • Content models: the CMS collections and fields behind repeated pages

Why it matters for B2B websites

B2B sites have to serve buyers who arrive with different questions: by product, by industry, by role, by problem. A structure built around your org chart, such as “Solutions”, “Platform” and “Resources”, often hides the page a buyer needs. A structure built around how buyers look for you puts it one click away.

IA also shapes SEO and AI search. A clear hierarchy with one page per topic, connected by internal links, tells crawlers what each page is about and which pages matter most.

How IA is planned

Teams start with an inventory of current content and data on what visitors search for and click. Card sorting asks users to group topics; tree testing checks whether they can find items in a proposed menu without the design. The result is a sitemap diagram and navigation plan approved before design starts.

Example

A data platform’s menu lists “Platform, Solutions, Resources, Company”. Buyers in sales calls ask “do you work with healthcare data?” and “how do you compare with X?”. A new structure adds industry pages and comparison pages to the menu, using the words buyers use.

How we handle it

Every project starts with the structure: what pages you need, what each one is for and how they link, agreed in writing before design. On a redesign we map every old page to its place in the new structure.

Is information architecture the same as a sitemap?

A sitemap diagram is one output of IA work. IA also covers navigation, labels, URLs and how content is modeled in the CMS.

Who is responsible for information architecture?

On website projects it is usually shared between a strategist or UX designer, the copywriter and the SEO lead, with input from sales on how buyers ask questions.

How deep should a B2B site’s structure be?

Shallow is usually better: key pages within two or three clicks of the home page. Deep nesting hides pages from visitors and crawlers.

How does IA affect SEO?

It decides which page targets which topic, how pages link to each other and how URLs are formed. A clear structure avoids several pages competing for the same search.
