CRUX #6: Information architecture in unexpected places

When we first think of a beautiful website or app design, we rarely think of content structures, labels, and categories. But that’s exactly where great design and seamless user experiences begin. Beneath fancy fonts, layout, colors, and animations are the real heroes of user-centric design - information architecture and navigation.

Information architecture (IA) is like the blueprint of your website or app - it’s a conceptual content structure of how content is organized and arranged to create seamless interactions. And as useful as your information may be, if your navigation is flawed, users won’t be able to find it. They’ll simply leave your site and look elsewhere.

So, how does navigation and information architecture complement each other to create seamless user experiences?

Understanding Information Architecture (IA)

Information architecture refers to the practice of organizing, structuring, and labeling content and information to enhance the user's understanding and navigation of a website or application. It involves designing an intuitive, user-friendly, and efficient system to help users find and access the information they need easily. Good IA is essential for delivering a positive user experience and ensuring that your users can achieve their goals effectively.
‍

IA is often confused with navigation structure. Navigation is a part of IA, and it refers to the way users move through a website or application. IA involves more than navigation; it encompasses the overall organization, labeling, and structure of content and information.
‍

Three Key Components of IA

There are three key components of IA:

• Organizational structure: Defines how information is organized, including the categories, subcategories, and relationships between them.
• Content structure: The way information is arranged and presented, including the hierarchy of information and the types of content used.
• Navigation structure: Outlines the pathways and components used for navigating through the information, such as menus, links, and search functions.

‍

‍

Navigation: A Vital Element of Information Architecture

Navigation refers to the process of providing users with a means of moving through a website or application to access the information they need. Navigation is an integral part of IA, as it guides users through the organizational structure and content structure of a site, allowing them to find and access the information they require efficiently.
‍

There are several types of navigation, including utility navigation and content navigation. Utility navigation refers to the elements that help users perform specific actions, such as logging in, creating an account, subscribing, or sharing content. Content navigation, on the other hand, refers to the elements used to guide users through the site's content, such as menus, links, and buttons.
‍

Both types of navigation provide users with a roadmap of how the site is organized and how they can access/interact with the information they need. Effective navigation structures are designed to be intuitive and easy to use. The goal is to minimize the time and effort required for users to find and access the information they need.
‍

‍

Key Elements of Effective Navigation

The key elements of effective navigation include clear labeling, logical grouping, and consistency across the site.

• Clear labeling helps users understand what information they can expect to find under each navigation element.
• Logical grouping ensures that related content is grouped together, making it easier for users to find what they need.
• Consistency ensures that users can predict how the site is organized and can find the information they need quickly and easily.

‍

‍

Designing Navigation for a Better User Experience

Since navigation structures need to be intuitive and easy to use, it goes without saying that usability testing is central to determining what is deemed ‘intuitive’ in the first place. What you might deem intuitive, may not be to your target user.
‍

We’ve discussed how clear labeling, logical grouping, and consistency are key elements for designing navigation, but can they be tested and confirmed? One common usability test is called card sorting. Card sorting is a user research technique that helps you discover how people understand, label and categorize information. It involves asking users to sort various pieces of information or content into categories. Researchers use card sorting to inform decisions about product categorization, menu items, and navigation structures. Remember, researching these underlying structures also informs your information architecture - a key factor in determining good website design.
‍

Tree testing is another invaluable research tool for creating intuitive and easy to use navigation structures. Tree testing examines how easy it is for your users to find information using a stripped-back, text-only representation of your website - almost like a sitemap. Rather than asking users to sort information, they are asked to perform a navigation task, for example, “where would you find XYZ product on our site?”. Depending on how easy or difficult users find these tasks gives you a great indication of the strengths and weaknesses of your underlying site structure, which then informs your navigation design.
‍

Combine usability testing and the following tips to nail your next navigation design:
‍

• Keep it simple: Simple navigation structures are easier for users to understand and use. Limit the number of navigation links and group related content together to make it easier for users to find what they need.
• Use clear and descriptive labels: Navigation labels should be clear and descriptive, accurately reflecting the content they lead to. Avoid using vague or confusing labels that could confuse users.
• Make it consistent: Consistency across the navigation structure makes it easier for users to understand how the site is organized and find the information they need. Use consistent labeling, grouping, and placement of navigation elements throughout the site.
• Test and refine: Usability testing is essential for identifying and refining navigation issues. Regular testing can help designers make improvements and ensure the navigation structure remains effective and user-friendly.

Best Practices for Information Architecture and Navigation

Both information architecture and navigation design contribute to great user experience (UX) design by making it easier for users to find the information they need quickly and efficiently. Information architecture helps users understand the relationships between different types of content and how to access them, while navigation design guides users through the content logically and intuitively.
‍

In addition to making it easier for users to find information, great information architecture and navigation design can also help improve engagement and satisfaction. When users can find what they're looking for quickly and easily, they're more likely to stay on your website or application and explore more content. By contrast, poor information architecture and navigation design can lead to frustration, confusion, and disengagement.
‍

So, when it comes to information architecture vs navigation, what are the best practices for design? Great navigation structure generally considers two factors: (1) what you want your users to do and, (2) what your users want to do. Strike a balance between the two, but ultimately your navigation system should focus on the needs of your users. Be sure to use simple language and remember to nest content into user-friendly categories.
‍

Since great navigation design is typically a result of great IA design, it should come as no surprise that the key design principles of IA focus on similar principles. Dan Brown’s eight design principles lay out the best practices of IA design:

• The principle of objects: Content should be treated as a living, breathing thing. It has lifecycles, behaviors, and attributes.
• The principle of choices: Less is more. Keep the number of choices to a minimum.
• The principle of disclosure: Show a preview of information that will help users understand what kind of information is hidden if they dig deeper.
• The principle of examples: Show examples of content when describing the content of the categories.
• The principle of front doors: Assume that at least 50% of users will use a different entry point than the home page.
• The principle of multiple classifications: Offer users several different classification schemes to browse the site’s content.
• The principle of focused navigation: Keep navigation simple and never mix different things.
• The principle of growth: Assume that the content on the website will grow. Make sure the website is scalable.

Summary: How User-Centered Research Elevates Your Information Architecture and Navigation

Information architecture and navigation are the unsung heroes of website design that work in synchrony to create seamless user experiences. Information architecture refers to the practice of organizing and structuring content and information, while navigation guides users through the site's structure and content. Both are integral to creating intuitive user experiences.
‍

In many ways, navigation and information architecture share the same traits necessary for success. They both require clear, logical structure, as well as clear labeling and categorization. Their ability to deliver on these traits often determines how well a website or application meets your users needs. Of course, IA and navigation designs should be anchored by user research and usability testing, like card sorting and tree testing, to ensure user experiences are as intuitive as possible!

"Dear Optimal Workshop

How do you make a small link attractive to people (icon vs. text)?"

— Cassie

‍

Dear Cassie,

‍

I'm going to dive straight into this interesting question with a good old game of Pros and Cons, and then offer a resolution of sorts, with a meandering thought or two along the way. Let's kick things off with Team Icon.

‍

The good side of icons: A picture is worth a 1000 words

‍

When shopping online, the number above the little shopping trolley icon tells me how badly behaved I’ve been, and if I click on it, I know I’ll get to gleefully review all the shoes I've selected so far. There’s a whole heap of icons out there like this that people have absorbed and can use without thinking twice. Marli Mesibov wrote a fantastic article on the use of icons for UX Booth on the use of icons that is well worth a look. Marli discusses how they work well on small screens, which is a definite bonus when you’re on the go! Young children who aren’t yet literate can easily figure out how to open and play Angry Birds on their parent’s smartphones thanks to icons. And icons also have a great capacity for bridging language barriers.

‍

The not so good side of icons: We’re too old for guessing games

‍

On the flipside, there are some issues that may huff and puff and blow that cute little home icon down. Starting with there being no consistent standard for them. Sure, there are a handful that are universal like home and print, but beyond that it seems to be a free-for-all. Icons are very much in the hands of the designer and this leaves a lot of room for confusion to grow like bacteria in a badly maintained office refrigerator. Difficult to understand icons can also seriously hinder a user’s ability to learn how to use your website or application. When icons don't communicate what they intend, well, you can guess what happens. In a great piece advocating for text over icons, Joshua Porter writes about an experience he had:

‍

"I have used this UI now for a week and I still have do a double-take each time I want to navigate. I’m not learning what the icons mean. The folder icon represents 'Projects', which I can usually remember (but I think I remember it because it’s simply the first and default option). The second icon, a factory, is actually a link to the 'Manage' screen, where you manage people and projects. This trips me up every time."

‍

If people can't pick up the meaning of your icons quickly and intuitively, they may just stop trying altogether. And now, over to Team Label.

‍

The good side of text: What you see is what you get

‍

Sometimes language really is the fastest vehicle you've got for delivering a message. If you choose the right words to label your links, you'll leave the user with very little doubt as to what lies beneath. It’s that simple. Carefully-considered and well-written labels can cut through the noise and leave minimal ambiguity in their wake. Quoting Joshua Porter again: "Nothing says 'manage' like 'manage'. In other words, in the battle of clarity between icons and labels, labels always win."

‍

The not so good side of text: Your flat shoe is my ballet pump

‍

Text labels can get messy and be just as confusing as unfamiliar icons! Words and phrases sometimes don’t mean the same thing to different people. One person’s flat enclosed shoe may be another person’s ballet pump, and the next person may be left scratching their head because they thought pumps were heels and all they wanted was a ballet flat! Text only labels can also become problematic if there isn’t a clear hierarchy of information, and if you have multiple links on one page or screen.  Bombarding people with a page of short text links may make it difficult for them to find a starting point. And text may also hold back people who speak other languages.

‍

The compromise: Pair icons up with text labels

‍

Because things are always better when we work together! Capitalise on the combined force of text and icons to solve the dilemma. And I don’t mean you should rely on hovers — make both text and icon visible at all times. Two great examples are Google Apps (because nothing says storage like a weird geometric shape...) and the iPhone App store (because the compass and magnifying glass would pose an interesting challenge without text...):

‍

‍

So what comes next? (You can probably guess what I'm going to say)

‍

Whatever you decide to run with, test it. Use whatever techniques you have on hand to test all three possibilities — icons only, text only, and icons and text — on real people. No Pros and Cons list, however wonderful, can beat that. And you know, the results will probably surprise you. I ran a quick study recently using Chalkmark to find out where people on the ASOS women's shoes page would click to get to the homepage (and yes, I can alway find ways to make shoe shopping an integral part of my job). 28 people responded, and...

‍

‍

‍

...a whopping 89% of them clicked the logo, just 7% clicked the home icon, and just one person (the remaining 4%) clicked the label 'Home'. Enough said. Thanks for your question Cassie. To finish, here's some on-topic (and well-earned) comic relief (via @TechnicallyRon)

What is information architecture? ✏️

‍

According to Abby Covert, a leader in the field of information architecture, IA is ‘the way we arrange the parts to make sense of the whole.’ Information architecture (IA) is found in every digital product, from websites and apps to an intranet. 

‍

For the purposes of this article we focus on the importance of information architecture to user experience (UX) design because IA is fundamentally important to the success of your user experience. It determines how users will access your  content and ultimately how successful their experience is when using your product. 

‍

When put like this it does seem pretty straightforward. Maybe even simple? But these tasks need to be straightforward for your users. Putting thought, time and research in at the front of your design and build can help build an intuitive product. IA is the structure that sits in behind and allows the design to tell the story and the content to be found in an easy way.

‍

The role of information architecture in UX design 🏗️

‍

Information architecture forms the framework for any UX design project. You need to consider the visual elements, functionality, interaction, and navigation and if they are built according to IA principles. If not considered fully even the most compelling content and powerful user experience design can fail without an organized and functional IA design. Disorganized content can make finding your way through difficult, meaning users get lost, annoyed and frustrated. Frustrated users don’t stick around and most likely don’t come back.

‍

Through solving or preempting users’ issues with research and designing powerful and effective IA it reduces usability and navigation problems. Meaning that researched, thought through and designed information architecture can save both money and time for your organization in the longer term.

‍

What is the difference between IA and UX? 🤯

‍

Often it can be confusing that there isn’t much difference between IA and UX design. While these terms do relate to each other and need to be considered alongside, they are not one and the same.

‍

“Information architecture (IA) is the discipline of making information findable and understandable, helping people understand their surroundings and find what they’re looking for online and in the real world” - Interaction Design

‍

“User experience (UX) design is the process design teams use to create products
that provide meaningful and relevant experiences to users” - Interaction Design

‍

UX design is well grounded with good functional information architecture but that’s not where it stops. The user experience focus is on influencing users’ behaviors and actions through emotion and psychology. Information architecture is focussed on the users' goals and task completion. They work together to create the very best user experience. IA provides the foundation of a well organized space that is easy to navigate and UX design ensures that the overall experience meets (or exceeds) users’ expectations, through their wants, needs and desires.

‍

The key components of IA 🧱

‍

There are four key components to consider when building a strong information architecture:

‍

Labeling

‍

How information is named and represented. Labels need to communicate information to users without using too much space or requiring much work on the user’s part.

‍

Navigation

‍

How people make their way through information. Without robust IA which has been thought through this is the quickest way to confuse users. If they can’t find their way to the information they need, they won’t be able to complete their task. It really is that simple.

‍

Search

‍

How people will look for information (keywords, categories). A search system is especially important when there is a lot of content to wade through. A search engine, filters, and many other tools help users search content. Great UX design will consider how the information will be displayed once searched.

‍

Organization

‍

How the information is ordered. These help users to predict where they can find information easily:

• Hierarchical is the hierarchy of the content and literally the order of importance
  the user expects to see information against what the organization needs.
• Sequential Taking a stroll in your user's shoes can be valuable. Considering the path a user would take and the journey they make. Walking step-by-step, ensuring that as users progress through their tasks they are easily led to the next step.
• Matrix This is a little more complicated for users as it lets them choose how to navigate on their own. Users are given the choice of content organization. For example, the searchability of a website. Where the user could choose to search by topic, size, price or any other filter or option.

‍

Wrap up 🥙

‍

Information architecture is a key part of a powerful user experience design. Efficient IA helps users quickly and easily move through content and find what they want.  And what do users want but to find what they want, complete their task and get on with their day!

‍

Provide an IA that functions well, is intuitive to use and well labeled, coupled with UX design that is smooth, attractive and responds to users needs, wants and desires and you’ll have a winner on the day.
