Diagnosing Navigation Flaws: Information Architecture Issues Behind Depth, Detours & Duplicate Categories

Why Navigation Problems Are Hard to Notice, Until You Try to Use Them

Navigation rarely fails in obvious ways.

Buttons are clickable. Pages load. Menus expand. From a product team’s perspective, everything looks functional.

But the real test of navigation isn’t whether it works. It’s whether it works without making the user think too much.

And this is where things quietly break.

You open an app to do something simple, update your email, download an invoice, change a password. You expect it to take a few seconds. Instead, you find yourself moving between sections that seem related, but don’t quite lead where you expected.

Nothing is technically wrong. But something feels off.

That “off” feeling is what poor navigation looks like in the real world.

For any ui ux agency, diagnosing this kind of friction requires looking beyond layouts and labels. It means understanding how users assume things are organised, and where that assumption breaks. In practice, this is an information architecture problem: the way categories, labels, and hierarchy are structured either matches how users think, or it doesn’t.

A Simple Test: “Where Would You Look First?”

One of the most effective ways to evaluate navigation is surprisingly basic.

Take any common task and ask:

If you had never used this product before, where would you go first?

Now compare that answer with where the feature actually lives.

The gap between those two is where navigation problems begin.

A Real Scenario: Updating Personal Details

Let’s say a user wants to update their phone number.

Most people mentally map this to:

• Profile
• Personal Information
• Account

But in many products, the actual path looks like:

• Settings → Security → Login Details → Contact Info

Each step individually makes sense. But together, they don’t match the user’s expectation.

So what happens?

The user:

• checks Profile first
• doesn’t find it
• moves to Settings
• explores multiple sections
• finally lands on the right place

This is not a usability failure in the traditional sense. It’s a navigation logic mismatch, and at its root, an information architecture mismatch, where the system’s categories don’t map to the user’s mental model.

And these mismatches are far more common than teams realise.

Depth: When “Just One More Click” Keeps Adding Up

Depth becomes a problem when users have to keep confirming they’re on the right path.

Not when there are multiple levels, but when each level introduces uncertainty.

What Depth Feels Like to a User

It doesn’t feel like “five levels of navigation.”

It feels like:

• “Maybe it’s in here…”
• “No, not here either…”
• “Let me try another section…”

That mental loop is what creates fatigue.

Where Depth Usually Goes Wrong

Depth tends to increase gradually over time.

• A new feature gets added under an existing category
• Another subcategory is introduced to “organise things better”
• Labels become more specific, but also more fragmented

Individually, each decision seems reasonable. Collectively, they create distance between the user and their goal.

A More Useful Way to Think About Depth

Instead of asking “How many levels do we have?”, ask:

• How many decisions does a user need to make before completing a task?
• At which step do they start second-guessing their choice?

Because the moment users start doubting their path, depth has already become a problem. In information architecture terms, this is a hierarchy problem, too many decision points stacked between the user and their goal.

Detours: The Silent Disruptor in Navigation

Detours are harder to spot because they don’t always look like errors.

They look like alternative paths that shouldn’t be necessary.

A Familiar Example: Downloading an Invoice

A user wants to download an invoice. Their expectation is straightforward:
Billing → Invoices

But instead, the structure leads them through:
Orders → Order History → View Order → Documents → Invoice

Now, think about what the user experiences:

• “Why is this under orders?”
• “Is invoice the same as receipt here?”
• “Did I miss a billing section somewhere?”

At no point is the system broken. But the user is constantly adjusting their understanding.

That adjustment is friction.

Why Detours Matter More Than Depth

Depth slows users down.
Detours make them uncertain.

And uncertainty is more damaging than delay.

Because once users stop trusting their path, they stop moving confidently.

Duplicate Categories: When the System Starts Competing With Itself

If depth and detours are structural problems, duplication is a clarity problem, and one of the clearest signs of weak information architecture.

And it’s one of the most common issues in growing products.

What It Looks Like in Practice

You’ll often see navigation with labels like:

• Account
• Profile
• Settings

Each of these contains overlapping elements.

So when a user wants to change something, say, their email, they pause.

Not because they don’t understand the task.
But because they don’t know where it belongs.

The Problem Isn’t Redundancy, It’s Ambiguity

Multiple categories are not inherently bad.

The issue is when categories are:

• conceptually similar
• poorly differentiated
• inconsistently structured

At that point, users are no longer navigating, they’re guessing.

How This Builds Over Time

Duplication rarely happens intentionally.

It usually comes from:

• different teams adding features independently
• no single owner responsible for the product’s information architecture
• incremental updates without restructuring

The result is a system that reflects how the product evolved, not how users think.

Hidden Pages: When Important Actions Are Technically There, But Practically Invisible

Some of the most critical features in a product are also the hardest to access.

Not because they’re meant to be hidden, but because they were never properly surfaced.

A Common Case: Deleting or Deactivating an Account

Users expect to find this under:

• Account Settings
• Privacy
• Security

Instead, they often have to:

• search for help articles
• follow indirect links
• go through multiple confirmations

Now, some friction here is intentional. But the problem arises when the path feels unclear rather than deliberate.

Visibility vs Accessibility

Just because something exists doesn’t mean it’s accessible. This is where information architecture and visibility intersect: a feature can be technically present and still be architecturally buried.

If users have to:

• search externally
• rely on guesswork
• or navigate unrelated sections

then the feature is effectively hidden.

How to Actually Diagnose These Issues (Without Overcomplicating It)

You don’t always need complex tools to identify navigation flaws. What you need is a shift in how you observe behaviour.

Start With Real Tasks, Not Screens

Pick a few common actions:

• update profile details
• download documents
• change account settings

Now try completing them as a new user would.

Notice where you:

• hesitate
• explore multiple paths
• feel unsure

Those moments are more valuable than any heatmap.

Look for Repetition in Movement

If users repeatedly:

• go back to the main menu
• switch between similar categories
• open multiple sections before finding the right one

it’s a sign the structure isn’t clear.

Pay Attention to Language

Sometimes the issue isn’t placement, it’s wording.

A label that makes sense internally might not match how users think.

And when language doesn’t align, even well-structured navigation can feel confusing.

Why This Matters More Than Teams Expect

Navigation issues don’t usually trigger direct complaints.

Users don’t say:
“Your information architecture is flawed.”

They say:

• “This took longer than expected”
• “I couldn’t find it easily”
• “I had to look around a bit”

Individually, these seem minor. Collectively, they shape perception, and collectively, they’re almost always a symptom of information architecture that grew reactively instead of being designed intentionally.

Over time, the product starts feeling:

• harder to use
• less intuitive
• slightly frustrating

And that perception is difficult to undo.

What This Means in Practice

For teams working on digital products, improving navigation is less about rearranging menus and more about removing unnecessary thinking.

At UX Prosperar, this usually involves stepping back from the interface and its underlying information architecture, asking simpler questions:

• What is the user trying to do here?
• Where would they expect to find it?
• What is making them pause?

Because once those answers are clear, the structure often becomes obvious.

And when the structure is right, users don’t notice navigation at all.

They just move.

Closing Thought

Good navigation doesn’t draw attention to itself.

There’s no moment where a user thinks, “That was a well-structured menu.”

Instead, the experience feels smooth, predictable, and effortless.

And that’s the real goal.

Not to impress users with organisation, but to make sure they never have to think about it in the first place.
