Making the homepage
worth opening

Sellers bypassed the Back Office homepage because it offered nothing worth stopping for. Redesigning the content layer turned it into the most-visited page in the product.

The one-minute version

The problem
Sellers had stopped using the homepage entirely, bookmarking Orders and Insights and routing around it. A 2022 migration had shipped technical parity but no answer to what they should actually look at when they arrived.
What I owned
Content strategy and full UX design for six new homepage blocks, a rebuilt Sales Insights data layer for Dynamic Pricing, and a consistency review spanning six seller-facing surfaces.
Result
4,800 → 22,000+ visits/month. The homepage went from the most-bypassed page in the Back Office to the most-visited page, above Orders, Wallet, and Insights.

The problem

A homepage nobody used

The Back Office homepage was technically functional and practically invisible. Sellers had carved their own paths through the product, bookmarking Orders, Insights, and Listings, and were routing around the homepage entirely. A FIDO study confirmed what the usage data already showed: sellers weren't asking for a better homepage because they'd stopped expecting anything from it.

Learned about features from the survey, not the product

The 2022 platform migration had shipped technical parity but left a fundamental question unanswered: what should a seller actually look at when they arrive? The homepage had no answer to that question, and a homepage with no answer is one sellers stop opening.

FIDO Research · Q1 2024

"The homepage is rarely used by anyone. Sellers bookmark other tabs and skip the homepage entirely."

Three needs emerged: Numbers (how am I performing), Notifications (what needs my attention), and Opportunities (what should I do next). The research also named Competitive Leaders (owners, CEOs, operational managers) as the primary design target.

Benchmarking against Amazon Seller Central, Shopify Analytics, and Mirakl confirmed the gap: every reference was either single-market or analytics-heavy with no action-orientation. There was no template to copy.

Scope & Ownership

Designing a system, not just a screen

The FIDO research established the problem clearly. What didn't exist yet was a content strategy: a considered answer to what sellers should actually see when they open the Back Office.

I designed the full content layer of the homepage: six new content blocks, a rebuilt data architecture for Back Market's Dynamic Pricing model, and a consistency review spanning six seller-facing surfaces.

The scope stretched well beyond a single screen. As the SellerXP designer, I held design ownership across six surfaces simultaneously: homepage, listings, orders, cost summary, finance report, and tooltips, each with its own engineering team, existing patterns, and its own answer to which price to display. Getting them to a consistent answer required commercial and finance sign-off.

The 1,700-seller base added a harder structural constraint: one layout, no segmentation, built for two very different audiences. Business owners doing a morning performance review. Operational sellers clearing a task queue. Designing for both meant making a deliberate call about who mattered most, and being prepared to defend it.

Design approach

Designing for the first 90 seconds

The FIDO research established how sellers actually start a session: three questions, in the same order, every time. The homepage needed to answer them before sellers navigated somewhere else.

I explored three layout directions before committing to anything. A dashboard-heavy layout with filterable charts was rejected first; it asked sellers to analyse at the exact moment they were arriving to get their bearings. A notification-first feed was rejected because it surfaces urgency without context: a seller can see something needs attention without knowing whether their overall performance is good or bad.

The editorial block model, developed jointly with a Content Designer (since a homepage is as much an editorial product as a functional one), won because it separates concerns cleanly. Performance first, tasks second, recommended actions last. Each block answers one question, in the order a seller naturally asks it.

Asset needed
Three layout directions — wireframes
Side-by-side low-fidelity wireframes showing the three directions explored before settling on the editorial block model: (1) Dashboard with filterable date-range charts, (2) Notification-first activity feed, (3) Editorial block sequence. Annotate each with the core reason it was rejected or chosen. The goal is to show the decision was reached through evaluation, not assumed from the start.
The three questions, in order
01 "How are we performing?"
Sales Insights
Orders, GMV, and refunds shown against the previous period and the same time last year. The comparison layer was the design decision that mattered most: a seller looking at €38,000 in monthly GMV has no way of knowing whether that's good, bad, or average without something to measure it against.
Trade-in Insights
Trade-in is a different operation from standard selling, and sellers running both were arriving at a homepage that treated it as invisible. This block gives them a separate performance view for a revenue stream that was growing and had no homepage representation before.
02 "What needs my attention right now?"
Task List
Over a million notification emails per month were leaving Back Market's servers: returns to process, buyer messages, compliance flags. Most were being ignored. Moving those prompts in-product, into the session where sellers can act on them immediately, was a product improvement and a business cost reduction in one decision.
Wallet
Only five of 52 sellers had found their payout dashboard before the redesign. Surfacing Wallet on the homepage was a discoverability emergency: it was the only surface every seller passed through.
03 "What should I do next?"
Listing Insights
A market-by-market table: stock levels and the percentage of listings held under BackBox (Back Market's automated pricing programme), sortable. For sellers operating across Germany, France, Spain, and beyond, this was the first time the Back Office gave them a cross-market inventory view without navigating into each market separately.
Opportunities
The last block in the sequence, deliberately. A seller who sees "lower your price on iPhone 13" before they've seen their sales trajectory has no frame of reference for whether that's the right call. The sequence builds context first: GMV, listings health, BackBox position. By the time Opportunities appears, the seller is already oriented; the recommendation arrives with something to weigh it against.
The hardest constraint

One homepage. 1,700 sellers with different businesses, markets, and priorities. FIDO showed that different seller types wanted different things: Competitive Leaders wanted performance data; operationally focused sellers wanted task queues. A single static layout couldn't serve both equally. Key Decision 1 covers how that was resolved.

The validation came from usage data: the homepage became the most-visited page in the Back Office, above Orders, Wallet, and Insights, within twelve months.

Key decisions

Three calls I'd make again

01

Design for the decision-maker, not the majority

FIDO identified two distinct seller types. Competitive Leaders — owners, CEOs, operational managers — started every session asking how the business was doing. Operationally focused sellers came in to clear their queue: processing returns, answering messages, chasing compliance flags. A single static layout couldn't serve both equally.

The safe option was to optimise for the most common seller type. But Competitive Leaders are 20% of sellers and drive 40% of GMV at twice the revenue per seller of the operational segment. When the PM pushed to design for the majority, the reframe that landed was: "We're not ignoring 80% of sellers. We're building for the users whose behaviour most directly affects platform health."

The layout would underserve operationally focused sellers in the short term, and that was an accepted trade-off. Personalisation was the planned next step. In 2024, the question was whether the homepage was worth opening at all.

Why value-per-seller matters more than share of base
Competitive Leaders (high-frequency) 20% of sellers → 40% of GMV
Operationally focused sellers 80% of sellers → 60% of GMV
Value per seller (GMV share ÷ seller share)
Competitive Leaders 2.0× average
Operationally focused sellers 0.75× average

Competitive Leaders generate 2× the average GMV per seller. Designing for the majority means optimising for the segment with less commercial weight per decision.


02

Show direction, not just state

The original Sales Insights block showed raw numbers: orders this month, GMV this month. Clean, minimal, and almost useless. A seller looking at €38,000 in GMV has no way of knowing whether that's good, bad, or the same as last week without a comparison period.

The team pushed for filterable date ranges, exportable charts, and multiple simultaneous metrics. But adding those controls would have turned an orientation surface into a second Insights page, undermining the one that already did that job. One clear signal per performance area — enough to tell a seller whether the Insights page is worth opening today.

Sales Insights before: raw numbers only, no trend indicators or comparison layer

03

When a new pricing model made every number on every screen wrong

Back Market's Dynamic Pricing Up model introduced an adjustment fee on top of the seller's listed price. The customer pays more; the seller's payout doesn't change. For the first time in the BO, three different numbers coexisted where one had always been sufficient.

Seller's price
€280
What the seller lists. Their payout is based on this figure.
Shown in GMV
+ Adjustment fee
+€22
Back Market's addition. The seller doesn't earn this; it must not appear in their revenue.
Customer pays
€302
If shown as the seller's GMV, it inflates revenue with money they never earned.

The homepage Sales Insights block had to make a deliberate editorial call: show €280, not €302. Showing the inflated figure would have given sellers a false read on their own revenue, and that kind of error on a financial surface compounds quickly.

The scope it created

The same call had to be made consistently across every surface where a price appeared. Inconsistency across six screens would have left sellers seeing different figures depending on where they looked.

Outcome

From most bypassed to most visited

In Q1 2024, FIDO research confirmed what usage patterns already showed: sellers had stopped using the homepage. By Q2 2025, it had become the single most visited page in the entire Back Office. The only material change between those two data points was the redesign.

#1
Most visited page
in the Back Office

From approximately 4,800 visits/month at the December 2023 baseline to over 22,000 visits/month by Q2 2025, roughly a fivefold increase over eighteen months, ending above All Orders, Wallet/Invoice, Insights, and every other page in the Back Office.

+268%
BO banner
engagement growth

Q1 to Q4 2025 (1,820 → 6,700 clicks/quarter). While seller email performance declined YoY, in-product engagement (built on the homepage as its foundation) became Back Market's highest-converting seller comms channel.

Email declined as in-product engagement grew
The design brief explicitly named reducing seller email volume as a goal. By 2025, seller email open rates declined 5.94pp YoY and CTR dropped 2.15pp, while BO banner engagement grew 268%. The Task List block was designed to pull notifications in-product; the channel data supports it.
Seller feedback, August 2024
"Back Market has launched an incredible new dashboard and it's a game-changer for sellers. The enhanced analytics are fantastic for getting deeper insights... This is amazing. It helps me work on every individual SKU to improve my sales and saves my time." — Seller (Gadget Basket LLC, US). A Seller Success Manager added: "My sellers have seen it and I check it regularly in my weekly calls with most of them. Super useful and only good feedback so far."
Continued investment as a signal
Back Market's Dynamic Pricing launch required a significant redesign of the Sales Insights block. The team invested in that work because sellers were actively using the homepage. Eighteen months earlier, they hadn't been.

How Back Market framed the homepage at BackForum 2025. The unified command center framing maps to the original three-question structure: performance, tasks, next actions.

What the data doesn't capture

The redesign established that the surface was worth using. What usage data can't tell you is whether sellers are getting what they actually came for, or just stopping by out of habit. Personalisation for different seller types is still on the roadmap and hasn't shipped yet.

Reflection

What I'd do differently

The redesign worked, but two structural calls are worth flagging. Both were defensible at the time and would be the first things I'd revisit on a second pass.

If I had the cycle again
Scope cross-surface consistency from day one

The six-surface price audit only happened because Dynamic Pricing forced it mid-project. With hindsight, surface-mapping should be a standard part of the brief on any system-level redesign, not a discovery triggered by an external launch. It would have saved late-stage rework and made the commercial sign-off conversation easier.

Open question
Whether one layout was the right answer

Designing for Competitive Leaders was the correct call given the constraint, but the constraint itself is worth challenging. Operationally focused sellers represent 60% of GMV; underserving them in the short term compounds. Personalisation is on the roadmap, and the right metric for whether this redesign succeeded long-term is whether the operational segment's session quality improves once it ships.

The Back Office homepage went from the screen sellers bypassed to the surface Back Market chose to carry its most significant pricing change. When Dynamic Pricing launched, Back Market surfaced the new revenue figures through the homepage. Sellers trusted a number they'd never seen before on a page they'd only started checking a year earlier.
