Information architecture is how the content of a site or app is organised, labelled, navigated and searched, so that people can find what they need, understand it and use it. It is one part of user experience design, and without it even the most striking site or app misses the mark. Get those four systems right and people find their way, and you decide the journey they take.
What is information architecture?
Architecture is an art: the careful design of a structure that meets practical and aesthetic needs. Information architecture does that for content. It guides people through your site, physical or digital, and makes sure the content that matters is clear, easy to find, easy to understand and easy to use.
Planned well, it makes a site inviting and enjoyable to use, with one purpose: helping people get what they need, quickly. Every site, app and store has one, and whatever the size of your site or business, taking it seriously gives you an advantage.
How should you organise your information?
Your organisational system is the foundation: it sets out how your information is divided. Most are hierarchical, sequential or matrix-based. Whichever you choose, its strength decides how useful your site is. A strong system helps people build a mental map of where they are, so exploring and finding things comes naturally.
Done well, it makes for a more satisfying experience: people spend more time, explore more and engage more. It helps your own team too: they know where information is, answer questions faster, make fewer mistakes and work more smoothly.
What makes good labels?
Labels are the most visible part of your information architecture. "Contact" and "Buy" buttons tell people what to do; menu options are labels too, and headings should follow a system that helps people find their way through the information. Use the words your users already know, and let each label and instruction lead to the next piece of information, with as little friction as possible.
Done well, labels raise conversion rates, because people find what they are looking for and move easily to the next stage of their journey. They also build credibility: care over labels presents information clearly, so even someone glancing at your site can feel they trust it, and your brand can build on that.
How should navigation work?
Navigation, often a menu, guides people through your site or app. You might highlight a few key categories, or show every subcategory. Either way, make it clear, give a path to every section you want people to reach, and keep it simple, so they can move between pages without feeling they have to start again from the home page.
Done well, navigation raises engagement: people who can move easily around a site explore more pages, find more of your products, services and content, feel more connected to your brand, and in the end buy more of what you offer. It also cuts support: customers want to help themselves, and a site that is easy to navigate answers the simple questions your support team would otherwise get.
Why does search matter so much?
Search boxes and filters let people skip the navigation and go straight to what they want, and they must be built on the right organisational system. If someone searches for something that should be on your site and gets no results, they give up and go to a competitor.
Good search finds relevant content, products and information and, structured well, can point customers to different or complementary options. Customers who find what they need quickly are more engaged and far more likely to come back. And search sells: people who can quickly find the product they want, or the answer that was holding them back, are more likely to buy.
What do you gain?
The information you want customers to see reaches them faster, so you control their journey: each one can be planned and mapped to lead people to what they came for, and to your business's goals.
