An independent review on the client’s side
The challenge and my role
A confidential company had invested in an automotive auction website delivered by an external agency. The client was unsure whether the result provided the depth, clarity, and credibility expected from a marketplace for high-value purchases. They needed an independent evaluation and a concrete list of revisions to take back to the delivery team.
I audited the existing experience, compared equivalent flows with established auction platforms, and translated the findings into prioritized change requests. My role was to explain what needed to change, why it mattered, and what the designers and developers should address next.
Project context | My contribution |
|---|---|
International automotive auction marketplace | UX/UI evaluation of buyer, seller, account, and support journeys. |
Existing agency-built interface and navigable prototype | Review of the delivered experience rather than a redesign from scratch. |
Client-side quality review | Competitive references, page-level recommendations, team tasks, and acceptance criteria. |
Mapping the complete marketplace experience
Looking beyond individual screens
I organized the review around the decisions buyers and sellers needed to make. This made it possible to identify gaps between pages, not just visual issues within them.
01 Discover the platform
02 Browse inventory
03 Evaluate a vehicle
04 Understand the auction
05 Bid or inquire
01 Understand selling
02 Prepare the listing
03 Submit a vehicle
04 Review and approval
05 Track the outcome
Area reviewed | Questions I evaluated |
|---|---|
Homepage and navigation | Can visitors recognize an active marketplace and find the right starting point? |
Search, filters, and auction cards | Can buyers narrow the inventory and compare relevant vehicles? |
Vehicle details and gallery | Is the information sufficient and organized for further consideration? |
Auction action and process guidance | Are timing, current bid, fees, responsibilities, and next steps clear? |
Seller submission | Does the platform explain requirements before asking sellers to log in or complete a form? |
Accounts, results, and support | Can users return to an action, understand status, find completed outcomes, and get help? |
Competitive analysis with a practical purpose
Four references, compared module by module
I compared the same marketplace modules across Bring a Trailer, Cars & Bids, Collecting Cars, and PCARMARKET. The objective was to find useful category patterns and adapt them to the client’s product, not copy entire competitor interfaces.
Reference | Patterns I used in the evaluation |
|---|---|
Bring a Trailer | Detailed auction context, current bid and timing, visible participation, results, and process resources. |
Cars & Bids | Early inventory visibility, strong bid/countdown treatment, vehicle specifications, grouped media, and practical buying/selling guidance. |
Collecting Cars | Live / Coming Soon / Results navigation, a clear auction action panel, seller support, and transaction explanations. |
PCARMARKET | Structured filters, visible high bid and time remaining, section navigation, documents, and marketplace-connected account activity. |
The benchmark became a reference for the correction brief. Each comparison supported a specific question: what information should be visible, where an action belongs, or how users should move through a scenario.
Homepage: from brand introduction to active marketplace
Restructuring the page around inventory and intent
The homepage already contained a hero, navigation, search, categories, auction cards, buyer/seller CTA panels, benefits, FAQ, and footer. The main problem was hierarchy: it introduced the brand more strongly than it communicated active inventory and auction behavior.
My recommended page structure
01. Hero + clear actions
02. Featured Live Auctions
03. Search / browse controls
04. Browse by Category
05. Coming Soon Auctions
06. Results / Sold Auctions
07. How It Works
08. Trust and support
09. Buyer / Seller actions
10. FAQ + structured footer
Recommendation | Specific direction |
|---|---|
Surface live inventory earlier | Place 3–4 live or featured auction cards directly below the hero or integrate them into the hero area. |
Replace generic exploration labels | Use actions such as “View Live Auctions”, “Sell Your Car”, and “How It Works”. |
Make search a marketplace tool | Use “Search by make, model, year” and relevant shortcuts such as Ending Soon and New Auctions. |
Separate upcoming and completed inventory | Use distinct Coming Soon and Results / Sold sections rather than mixing different auction stages. |
Make trust content useful | Link inspection, payment, verification, and support statements to concrete process information. |
Example: the How It Works preview
Browse auctions → Register / verify your account → Place a bid → Complete payment / delivery
The homepage preview would link to the full guide, buyer fees, auction rules, and support. This connects a simple introduction with the details users need before participating.
Auction discovery: filters, sorting, and recovery
Helping buyers move from a broad grid to a relevant shortlist
The auction page provided a title, result count, city filter, price sorting, and a card grid. Search existed globally, but the page itself lacked several controls useful for auction-specific browsing.
Control group | Recommended content |
|---|---|
Search | “Search by make, model, year, keyword” directly above the grid. |
Primary vehicle filters | Location, make/model, year range, category/body style. |
Additional filters | Mileage, current bid/price range, reserve status, and auction state where supported. |
Auction sorting | Ending Soon and Newly Listed first; additional price/bid and mileage options as appropriate. |
Status paths | Live Auctions, Coming Soon, Results / Sold. |
Applied filters | Visible removable chips, updated result count, and Clear All. |
Example: no-results state
No auctions match your filters
Clear filters · Browse all auctions · View coming soon
I also recommended predictable loading or pagination, clearer card click behavior, and a mobile Filter & Sort drawer or bottom sheet. The aim was to help people refine, understand, and recover their search rather than leave them at a dead end.
Auction cards: one reusable comparison pattern
Making bid, time, and vehicle identity easy to scan
The reviewed cards included pricing and participant information, but timing, bid hierarchy, and action clarity needed improvement. I recommended defining the card anatomy once and reusing it across the homepage, listings, and related auctions.
Card element | Recommended treatment |
|---|---|
Vehicle identity | Year + make + model + trim, with consistent truncation. |
Primary auction information | Clearly labeled Current bid or Starting bid, plus visible time remaining. |
Activity | Distinguish number of bids from number of participants. |
Vehicle metadata | Location, mileage, and a small set of useful specifications. |
Status and confidence | Separate auction lifecycle, reserve conditions, and verification labels. |
Primary action | Use an explicit “View Auction” action instead of relying on an ambiguous icon. |
Secondary action | Watch / Save where supported. |
Different states need different information
State | Information and action |
|---|---|
Live | Current bid, countdown, relevant activity, and View Auction. |
Coming Soon | Start date/time and watch or reminder intent, where supported. |
Completed | Confirmed outcome, end date, and View Result rather than an active bidding action. |
Vehicle detail: a page for making a decision
Bringing evidence and the auction action together
The existing page had a large gallery, thumbnails, a title, state, location/model information, current and starting prices, participant/bid counts, and a short description. I recommended reorganizing those foundations into a more complete auction decision page.
01. Back to Auctions + vehicle title
02. Gallery + auction panel
03. Vehicle details
04. Structured description
05. Documents / history
06. Seller and support
07. Bid history
08. Related auctions
A dedicated auction action panel
Current bid · Starting bid · Time remaining · Bid count · Auction state
Place Bid / Login or Register to Bid
Watch · Share · How bidding works
These items needed to work as a coherent action area, not compete as scattered metadata. I also recommended compact action access after scrolling, with mobile treatment that keeps the bid and time visible without blocking the page.
A more useful gallery
Replace standalone image opening with an in-page fullscreen viewer. Add photo count, thumbnail navigation, previous/next controls, and clear close/back behavior. Where media is available, organize it into Exterior, Interior, Mechanical, Documents, and Other.
Vehicle information and transaction clarity
Structuring content around buyer questions
Module | Recommended content |
|---|---|
Vehicle details | Make, model, year, mileage, engine, transmission, drivetrain, VIN, title status, colors, fuel type, and location where available. |
Description | Highlights, Equipment, Modifications, Known Flaws, Recent Service History, Ownership History, and Seller Notes. |
Documents / History | Vehicle history, inspection, service records, ownership, and relevant export documents; clear view/download actions. |
Seller / Support | Seller type, Ask a Question, Contact Support, and the platform’s actual role. |
Transaction guidance | Applicable buyer fees, payment expectations, inspection responsibilities, shipping/export context, and what happens after winning. |
Bidding history | Latest bids and timestamps, with an appropriate bidder-identity treatment. |
I specified missing-information behavior as well as content structure. Documents or verification that are not available should not be implied by polished badges or empty sections. “No documents uploaded yet” is more useful than leaving the buyer unsure whether content failed to load.
Seller submission: a journey, not just a form
Explain the process before asking for commitment
The public Create Auction path led to login. I recommended a public Sell Your Car entry explaining vehicle eligibility, preparation, photos, documents, fees, inspection expectations, review, and support before the submission flow.
Recommended submission steps
01. Vehicle Basics
02. Auction Setup
03. Vehicle Details
04. Photos
05. Documents
06. Seller Details
07. Review & Submit
Step / state | Specific recommendation |
|---|---|
Preparation | Provide a checklist for vehicle details, photos, ownership documents, available reports, and reserve expectations. |
Photo upload | Explain required angles and useful coverage: exterior, interior, engine, odometer, and known flaws. |
Form behavior | Persistent labels, required/optional fields, helper text, validation, and draft saving if supported. |
Review | Show a listing preview and missing-information warnings before submission. |
Primary action | Use “Submit for Review” when publication requires platform review. |
Confirmation | Explain receipt, the review process, notification method, support, and where to track status. |
Draft → Submitted → Under Review → Needs Edits / Approved → Scheduled → Live → Final outcome
The recommended state model gives sellers a clear expectation of progress and gives the team a basis for designing confirmations and account views.
Education, results, accounts, and support
Closing the gaps between discovery and participation
Area | My recommendations |
|---|---|
How It Works | Separate How to Buy and How to Sell. Explain bidding, reserve conditions, applicable fees, responsibilities, and what happens after an auction closes. |
Results / Sold | Provide dedicated access and a completed-inventory state in browsing. Show genuine outcomes and retain relevant vehicle information. |
Account activity | Connect basic profile details to bids, saved vehicles, seller submissions, verification, and notification preferences where supported. |
Login continuation | Explain the action requiring login and return users to the original auction or submission task afterward. |
Support routing | Use topics such as buying/bidding, selling, payment/fees, shipping/export, verification, and account access. |
Contact confirmation | Confirm that the message was sent and explain the next step and realistic response expectations. |
Visible contact access was an existing strength. I recommended preserving it while adding relevant support links near vehicle details, seller submission, and transaction guidance. These recommendations connected help to the moment of uncertainty rather than treating it only as a footer destination.
Delivering tasks the team could use
From audit finding to implementable revision
I organized findings into page-specific change requests with priority, rationale, and acceptance criteria. This gave the client a structured basis for asking the agency for revisions.
Change request | Review criteria |
|---|---|
Add visible time remaining to active cards. | Use consistent countdown formatting; make ending-soon treatment clear; keep it readable on mobile. |
Create the auction action panel. | Current bid, countdown, bid count, state, and correct participation action are grouped and visible. |
Improve browsing controls. | Relevant filters and sorting are available; selected filters and result counts are clear; users can reset. |
Define results states. | Completed outcomes are distinguished; active bidding is removed; relevant next actions are available. |
Complete seller submission. | Preparation, structured steps, preview, confirmation, and review-status guidance are covered. |
Priority logic
I prioritized changes affecting discovery, auction understanding, bidding confidence, vehicle evaluation, and seller preparation ahead of lower-level visual refinements. Shared card, state, and navigation recommendations supported consistent revisions across pages.
What I delivered
