E-Commerce in Motorisation:

UX Review of Autodoc.pl

Autodoc.pl is one of the largest online platforms for purchasing car parts and accessories in Europe. However, even in such a robust and established system, there is room for UX improvement.

As a UX designer, I aim to showcase my ability to review and evaluate e-commerce platforms. This case study highlights opportunities where Autodoc.pl could simplify and optimize the user journey.

Introduction
My Goals

Issue 1: Cart Item Removal Interaction

Observation:


When a user removes an item from the cart, a pop-up window appears. This behavior feels like a technical glitch or an unintended system message rather than a clear, user-friendly interaction.

Why it’s a problem:

  • Pop-ups interrupt the user journey.

  • They signal “error” instead of normal system behavior.

  • They create friction in a moment that should be smooth and predictable.

Recommendation:

Replace the pop-up with an inline, friendly confirmation message, for example:

“Oops, your cart is empty. Let’s find something for your car!”

And nearby provide quick navigation links to main categories such as:

  • Brakes

  • Tires

  • Batteries

  • Oils & Fluids

  • Lighting. etc.

Issue 2: Product Category Structure

Observation:


Speaking about product categories, the category system is visually heavy. The use of large photos distracts the user and slows down scanning.

Why it’s a problem:

  • Large polichromatic images add cognitive load.

  • Users may focus on the visuals instead of quickly identifying the needed product type.

Recommendation:


Use a simplified icon-based category navigation consistently. The platform already has well-designed, monochrome icons in the left drawer menu—these should replace the large photos across the interface for a cleaner, faster browsing experience.

Issue 3: Icon Recognition

Observation:


The category system is visually heavy. The use of large photos distracts the user and slows down scanning.

Why it’s a problem:

  • Large polichromatic images add cognitive load.

  • Users may focus on the visuals instead of quickly identifying the needed product type.

Recommendation:


Adopt a simplified icon-based category navigation (like the drawer menu on the left side of the site). Use monochrome, recognizable icons for clarity and consistency.

Issue 4: Color Palette

Observation:


The platform has two color combination for header: dark navy #132530 and dark orange #F85A00, second is dark navy #132530 and light grey #8E979D.

Both of them are distinctive and creates low contrast in some areas and reduces readability.

Why it’s a problem:

  • Poor contrast harms accessibility.

  • Dark tones may overwhelm users during extended browsing sessions.

  • Text may still feel “washed out” on smaller screens or under lower brightness.

  • Users with mild visual impairments or older displays could struggle with legibility.

Recommendation:


Increase contrast by darkening text (closer to pure black #000000) or lightening the grey background.

  • Use the grey #8E979D more sparingly (for borders, icons, inactive states), while keeping text on higher-contrast backgrounds.

  • Consider a more neutral light palette (e.g., off-white #F4F4F4) to balance the dark navy.

Contrast ratio analysis (using whocanuse.com)

  • Navy #132530 on grey #8E979D has a contrast ratio of 5.29:1.

  • According to WCAG accessibility standards:

    • AA level: requires 4.5:1 for normal text and 3:1 for large text → this passes.

    • AAA level: requires 7:1 for normal text and 4.5:1 for large text → this fails.

Conclusion

  • Consistency matters: Using the same icon style and structure across the platform simplifies navigation and strengthens visual hierarchy.

  • Clarity builds trust: Replacing disruptive pop-ups with inline messages creates a smoother and more reliable shopping flow.

  • Accessibility enhances usability: Improving color contrast and pairing icons with text ensures better readability for all users.

  • Small changes, big impact: Even minor visual and interaction adjustments can elevate user comfort and make the e-commerce experience feel effortless.
