Category navigation menus help users orient themselves and discover products efficiently across large catalogs. For product designers and managers, the challenge is structuring content and labels so users can find what they need quickly without confusion.
Category Navigation Menu Testing uses a design stack of UX metrics: usability, comprehension, and satisfaction to measure how easily users can explore and locate desired categories. This approach replaces subjective opinions with measurable insights.
With these findings, designers and managers can make informed design decisions, prioritize improvements, and demonstrate the impact of changes on business outcomes. For example, testing Lululemon’s “We Made Too Much” navigation menu revealed high comprehension but lower usability, showing where hierarchy and link clarity could be refined to improve browsing efficiency.
Define Goals for Your Category Navigation Menu
A category navigation menu should balance user needs like clarity, organization, and speed with business goals such as discoverability, engagement, and conversion. Users want to find products that match their interests without confusion, while businesses want to guide shoppers toward high-value categories and items. Measuring how users interact with navigation ensures the structure supports both exploration and purchase intent.
**Audience:**
This concept was tested with online women shoppers in the United States exploring the Lululemon website’s category navigation menu. Participants were asked to browse the “We Made Too Much” section and share impressions of clarity, organization, and ease of finding products that matched their preferences.
User Needs
As a customer using a category navigation menu on a retail site, the five most important needs would be:
-
Categories and products should be clearly labeled and easy to locate. (Categories should be Findable)
-
The navigation structure should be simple and consistent across desktop and mobile. (Navigation should be Usable)
-
The hierarchy and grouping of categories should make sense at a glance. (Navigation should be Intuitive)
-
The menu should allow users to reach desired products quickly, with minimal clicks. (Menu should be Efficient)
-
The design and language should reflect the brand’s style and make browsing enjoyable. (Design should be Desirable)
These five ensure the navigation feels clear, organized, and on-brand, helping shoppers move smoothly from interest to action.
Business Goals
Here are the five most important business goals for a category navigation menu:
-
Increase Product Discoverability – Surface key product categories, collections, and promotions effectively.
-
Drive Conversion Pathways – Lead customers toward purchase-ready pages like product listings or curated collections.
-
Highlight Brand Priorities – Emphasize strategic items (e.g., seasonal drops or clearance categories) through menu placement.
-
Reduce Drop-Off Rates – Keep users browsing longer by simplifying wayfinding and reducing friction.
-
Gather Navigation Insights – Track clicks and hover behavior to improve information architecture and merchandising strategy.
These goals help the business optimize product discovery, guide conversion, and strengthen brand consistency through effective category navigation.
Choose Metrics to Test Your Category Navigation Menu
For Lululemon’s e-commerce navigation menu, a design stack of four UX metrics was chosen to measure how effectively the menu helps shoppers explore product categories and find what they need. This stack — Usability, Effort, Success, and Sentiment — was established by mapping user needs directly to measurable outcomes:
-
Usable & Intuitive → Usability
The menu should feel natural to use, allowing shoppers to browse categories with minimal thought. Usability measures whether participants can easily understand and interact with the navigation structure. -
Efficient → Effort
The navigation experience should minimize the steps it takes to reach a product page. Effort evaluates how easy or difficult participants found it to browse through the menu and reach their intended destination. -
Findable → Success
Shoppers should be able to locate the right category or collection without confusion. Success measures whether participants successfully found the path to the correct section on their first try. -
Desirable → Sentiment
The menu should feel visually appealing and enjoyable to interact with. Sentiment captures how participants emotionally respond to the design, such as feeling inspired, satisfied, or frustrated.
Establish Hunches to Direct Your Testing
Navigation menus define how easily users can explore, discover, and act within an e-commerce experience. For Lululemon, the “We Made Too Much” section represents both a major conversion driver and a unique brand touchpoint — one that must balance urgency with clarity and trust. The following hunches identify potential design assumptions and guide what to validate through user testing.
Example: Lululemon E-Commerce Navigation
<table xmlns="http://www.w3.org/1999/xhtml" style="min-width: 75px;"><colgroup><col style="min-width: 25px;"><col style="min-width: 25px;"><col style="min-width: 25px;"></colgroup><tbody><tr><th colspan="1" rowspan="1"><p>Hunch</p></th><th colspan="1" rowspan="1"><p>Question</p></th><th colspan="1" rowspan="1"><p>UX Metric</p></th></tr><tr><td colspan="1" rowspan="1"><p>The “We Made Too Much” label may not immediately communicate that this section contains discounted or clearance products, leading some shoppers to overlook its value.</p></td><td colspan="1" rowspan="1"><p>What do you expect to find when clicking on the ‘We Made Too Much’ section</p></td><td colspan="1" rowspan="1"><p><a target="_blank" rel="noopener noreferrer nofollow" href="https://glare.helio.app/define/ux-metrics/attitudinal-metrics/expectations">Expectations</a></p></td></tr><tr><td colspan="1" rowspan="1"><p>The left-aligned category list (Women’s, Men’s, Accessories, Bags, Shoes) feels minimal but may require extra effort to scan compared to a visual layout with product imagery or icons.</p></td><td colspan="1" rowspan="1"><p>Was it easy to find the product category you were looking for?</p></td><td colspan="1" rowspan="1"><p><a target="_blank" rel="noopener noreferrer nofollow" href="https://glare.helio.app/define/ux-metrics/behavioral-metrics/effort">Effort</a></p></td></tr><tr><td colspan="1" rowspan="1"><p>The navigation hierarchy lacks visible differentiation between primary menu items and the sub-menu, which could cause users to misclick or hesitate when exploring.</p></td><td colspan="1" rowspan="1"><p>How confident did you feel navigating between main categories and sub-categories?</p></td><td colspan="1" rowspan="1"><p><a target="_blank" rel="noopener noreferrer nofollow" href="https://glare.helio.app/define/ux-metrics/behavioral-metrics/usability">Usability</a></p></td></tr><tr><td colspan="1" rowspan="1"><p>The supporting banner and tagline (“Gone before you know it”) may evoke urgency effectively but risks overshadowing the usability of the actual links.</p></td><td colspan="1" rowspan="1"><p>What drew your attention first — the banner image or the product category links?</p></td><td colspan="1" rowspan="1"><p><a target="_blank" rel="noopener noreferrer nofollow" href="https://glare.helio.app/define/ux-metrics/behavioral-metrics/engagement">Engagement</a></p></td></tr><tr><td colspan="1" rowspan="1"><p>The feedback tab on the right side of the screen might distract from the main navigation task or add cognitive load for users scanning the menu.</p></td><td colspan="1" rowspan="1"><p>Did the feedback option on the right side feel helpful or distracting while navigating?</p></td><td colspan="1" rowspan="1"><p><a target="_blank" rel="noopener noreferrer nofollow" href="https://glare.helio.app/define/ux-metrics/attitudinal-metrics/sentiment">Sentiment</a></p></td></tr></tbody></table>
These hunches help test whether Lululemon’s navigation strikes the right balance between clarity, urgency, and usability, ensuring customers can confidently explore deals without friction or confusion.
Turn Hunches into Test Questions
Turning these metrics into participant questions transforms design assumptions into measurable signals. Each metric uses a specific question type paired with a clear example from Lululemon’s site navigation:
- Usability **(Click test success across multiple directives)**
Question type: Multi-task click test.
Example: “Where would you click to browse women’s running leggings?” followed by “Where would you click to find accessories or yoga mats?”
[Image]
- Effort **(7-pt scale of difficulty)**
Question type: Difficulty rating scale.
Example: “How easy or difficult was it to find what you were looking for using this navigation menu?” (1 = Very Easy → 7 = Very Difficult)
[Image]
- Sentiment **(Multiple-choice impressions)**
Question type: Impression checklist.
Example: “Which of the following words best describe your impression of this navigation menu?” (Positive: Organized, Clear, Stylish, Helpful. Negative: Confusing, Cluttered, Overwhelming, Slow)

Calculate UX Metric Scores from User Feedback
We tested Lululemon’s e-commerce site navigation with 100 participants, and their responses were analyzed to generate UX metric scores on a 0–100% scale. Each metric in the design stack was derived from a mix of first-click tasks and follow-up survey questions, then benchmarked using the following thresholds:
-
Very Good = 90% and above
-
Good = 70%–89%
-
Average = 50%–69%
-
Poor = 30%–49%
-
Very Poor = below 30%
Once the individual UX metric scores are calculated, the average of those scores are used to determine the overall score for the user experience.
Lululemon’s Results
-
Usability (79% — Good): Most participants could efficiently locate major product categories like “Men,” “Women,” and “We Made Too Much,” showing strong IA structure and predictable grouping.
-
Effort (85% — Good): The navigation system required minimal scrolling or back-tracking, indicating efficient pathways and intuitive hierarchy for browsing.
-
Sentiment (46% — Poor): While functional, emotional reactions to the nav were muted — participants described it as “plain” or “uninspiring,” suggesting missed opportunities for personality or brand energy.
[Image]
These outcomes resulted in an overall test score of 70% — Good. Lululemon’s category navigation successfully supports efficient browsing but lacks emotional engagement. Enhancing sentiment through subtle motion, richer imagery, or micro-interactions could make the experience feel more vibrant and aligned with Lululemon’s premium brand personality.

Draw Signals from Your Design Stack
Here’s how signals were surfaced from the Lululemon nav menu test results by following these five steps:
1. Focus on poorly scoring metrics
[Image]
Lululemon’s category navigation scored a good overall score of 70%, with strong marks in Usability (79%) and Effort (85%), showing that the menu is simple to use and quick to navigate. However, Sentiment scored poorly at 46%, indicating that while shoppers can easily find what they need, the experience feels somewhat impersonal and lacks the emotional spark associated with Lululemon’s brand energy. The data suggests a functional but uninspiring navigation experience.
2. Identify patterns across metrics
[Image]
The mix of strong functional scores and weak sentiment reveals a gap between usability and emotional connection. The structure and clarity of the menu work well, but the design language doesn’t evoke excitement or reinforce the premium, aspirational feel of the brand. Shoppers efficiently reach destinations but aren’t compelled to explore or feel immersed in the brand story along the way.
3. Determine if user needs are being met
[Image]
-
Findable: Met — categories are clearly labeled and easy to locate.
-
Usable: Met — consistent structure supports intuitive browsing across desktop and mobile.
-
Intuitive: Met — hierarchy is logical and supports quick scanning.
-
Efficient: Met — users reach desired destinations with minimal effort.
-
Desirable: Not fully met — the minimalist layout feels practical but lacks the brand’s typical vibrancy or emotional appeal.
4. Compare outcomes to your business goals
-
Increase Product Discoverability: Supported — users can easily find key product categories and promotions.
-
Drive Conversion Pathways: Supported — clear structure directs users toward purchase-ready sections.
-
Highlight Brand Priorities: Limited — weak sentiment suggests brand messaging isn’t strongly conveyed through navigation.
-
Reduce Drop-Off Rates: Supported — efficient wayfinding keeps users browsing longer.
-
Gather Navigation Insights: Supported — clear paths enable tracking of behavioral data and optimization opportunities.
5. Surface signals & establish a direction
**
Signals derived from the data:**
-
Navigation works but lacks brand energy — users find products easily but don’t feel the personality or excitement of Lululemon’s brand.
-
Usability drives exploration, not emotion — clear menus guide shopping efficiently but don’t elevate the experience.
-
Design feels functional, not aspirational — the practical layout doesn’t communicate the active, premium lifestyle tone the brand is known for.
Direction based on business context: To align with Lululemon’s goals of increasing product discoverability and highlighting brand priorities, design improvements should focus on:
-
Adding brand cues (e.g., imagery, typography, or tone) that reinforce energy and lifestyle identity.
-
Highlighting key categories and seasonal drops through more expressive visuals or micro-animations.
-
Maintaining simplicity while layering in emotional touchpoints that remind users of the brand’s movement-driven purpose.
Based on the signals and design direction, we created an updated version of the design with the expected UX metric improvement:

The signal is clear: Lululemon’s category navigation is efficient and easy to use but lacks brand personality. Enhancing emotional resonance and visual engagement will turn navigation from a utility into a brand-building moment.
