Information architecture in plain English
Think of IA as the floor plan of your website. Before anyone chooses colours or writes copy, you decide which rooms (pages) the site needs, what to call them and how people move between them. A visitor should be able to land on any page and quickly answer three questions: Where am I? What can I do here? Where should I go next?
Why IA matters for conversion and SEO
- Visitors find what they need faster, which reduces cognitive load and drop-off.
- The path to an enquiry is clearer. Good IA puts services, proof, prices and contact options where people expect them along the customer journey.
- Search engines understand your site better. A logical structure with clear page names and internal links helps Google and AI assistants work out what each page is about and which pages matter most.
- The site can grow without becoming a mess. New services and locations have an obvious home.
The building blocks of IA
- Sitemap: the full list of pages and how they are grouped.
- Navigation: main menu, dropdowns, footer and breadcrumbs.
- Labels: the words used for menu items and page titles. Use your customers' words, not internal jargon.
- URL structure: short, readable addresses that reflect the structure, such as /services/physiotherapy.
- Internal links: the links between related pages, like the related terms in this glossary.
How to plan your information architecture
- Start with research. List what customers ask, search for and compare before they enquire.
- Inventory your content. Note every existing page, what it is for and how it performs.
- Group and label. Card sorting, where people sort topics into groups that make sense to them, shows how customers expect information to be organised.
- Draft a sitemap and keep the main menu short (see Hick's law).
- Test it. Tree testing asks people to find things using only the menu structure, before any design work starts.
- Plan redirects if page addresses change, so you do not lose search rankings.
Common mistakes
- Organising the site around your internal teams instead of customer needs.
- Vague labels such as "Solutions" or "What we do".
- Important pages buried three clicks deep, or only reachable from the footer.
