Proximus
Two UX research tracks at Proximus in 2019: the Bizz Online page, redesigned from twenty-five interviews with freelancers, and price perception, a track I started myself.
Key result
+38% conversion on the redesigned Bizz Online page, measured by Proximus' internal analytics.
01 Bizz Online
A name that meant nothing, a price that worried.
Context
Bizz Online was Proximus' offer to have your website built by an expert: three plans, S, M and L, from €15 to €70 a month, aimed at freelancers and small businesses. It wasn't taking off. The need was real: in 2019, a freelancer knows they need an online presence. The question was what stood in the way. I led the initiative end to end, from research to launch, and ran the French-language interviews.
Objectives
- Understand the need — what a freelancer expects from a website, and from whoever builds it.
- Understand the blocker — why the offer failed to convince: awareness, understanding of the service, price.
- Redesign the page — a page that answers the questions before showing a price.
- Verify — measure in a second round what the redesign had fixed, and what was left to do.
Approach
- Fifteen interviews in August 2019 — seven in French, eight in Dutch, with freelancers with or without a website, one hour each: open questions about their relationship with the web, then discovering the Bizz Online page as it stood.
- Reading across four environments — product, service, support and web, to separate what the page could fix from what belonged to the offer itself.
- Page redesign — information architecture, UX copy and mobile-first wireframes: value and steps before price, a detailed price (VAT, setup fee, commitment period), explained vocabulary. Then following the build with the e-marketing team.
- Second round in November 2019 — ten interviews, five in French and five in Dutch, on the redesigned page, to test four assumptions: is the process understood, can people pick a plan unaided, do they want to build their own, is the copy clear?
What the interviews showed
- "Bizz Online" means nothing — eleven participants out of fifteen could not guess it was about building a website; some thought of myProximus, one of the Yellow Pages.
- The price worries because nobody knows what it covers — twelve out of fifteen: what do you get for €15, €50 or €70 a month, is VAT included, and for how long? They pictured a website at €1,000 to €5,000, without seeing that €70 a month came out cheaper.
- They want a person, not a case number — ten out of fifteen expect a dedicated expert, advice and a path to autonomy; "digital coach" made them think of a machine.
- Jargon gets in the way — "responsive", "domain name", a "catalogue" mistaken for an online shop, and "copywriting" read as protection against plagiarism.
- The stepper hid the process — most participants did not see the creation steps, or did not read them.
"Copywriting, what does that mean? So nobody can copy my website?"
Results
- Page redesigned and launched — value and steps before price; VAT, setup fee and commitment period displayed.
- +38% conversion — measured by Proximus' internal analytics on the redesigned page.
- Transparency appreciated — in the second round, the two-year commitment was read and appreciated, but judged too long for a small business.
- Recommendations beyond the web — the name, rigid plans, a two-year contract: co-creation with freelancers, a design sprint and a coaching offer put to the product teams.

02 Price perception
One pack, four prices.
Context
While running interviews for other Proximus projects, I kept hearing the same complaint, project after project: Proximus is expensive, and you never know what you'll actually pay. With the operator's NPS stalling, I proposed turning it into a research track of its own, to check whether the way prices and promotions were announced, in print and on the web, was feeding that distrust. I ran the audit, the benchmark and the interviews, then wrote the recommendations.
Objectives
- Put internal assumptions to the test — "our promotions are clear", "a price ending in .99 performs better", "promotions are what make people switch operator".
- Measure the effort required — how many calculations does it take to know your final price, and for how long it applies?
- Benchmark the market — how VOO, Orange, Telenet, Scarlet and Free display their prices and promotions.
Approach
- Purchase journey audit — four residential packs (Tuttimus, Familus, Epic Combo, Minimus) and the SME pages. On Familus, the same pack showed €77.99 in the comparison table, no price on its own page, €69 in the sticky header, and hinted at €59 on the summary. Often the price changed again when opening the offer details: it adapted to the visitor's profile, or an unexplained rule kicked in.
- Evaluation frameworks — Bastien & Scapin ergonomic criteria (guidance, consistency, explicit control) and Nielsen's heuristics, backed by reading on the psychology of numbers and pricing.
- Five-operator benchmark — VOO, Orange, Telenet, Scarlet and Free, compared on net price, stated savings, round prices and displayed promotion length.
- Eight bilingual interviews — four in French, four in Dutch, with competitors' customers, run in pairs (one leads, one takes notes), followed by a collective unpacking on the wall.
- Evidence-based recommendations — each display principle backed by a source: sale price to the right of the struck-through price, total savings stated, round prices, one word for one promotion.
What the interviews showed
- "It's a trap" — small print and hard-to-find conditions make every promotion read as a scam.
- Nobody knows what they'll pay once the promotion ends — is the web discount already applied? What about month four? A price that changes between the page and its details settles the doubt for good.
- €10 for three months moves nobody — to switch operator, participants mentioned savings of €70 to €150.
- Words matter — "All in" suggests unlimited; "webdeal" means nothing to most, participants say "web promo".
- Switching operator takes time — two to three weeks of thinking it over, longer for a family.
"I don't know, I'll scroll down the page…"
Results
- Assumptions settled — six findings validated; "our promotions are clear" did not hold up against users.
- "Webdeal" dropped — the term left the copy from the very next promotion.
- Price display principles — handed to the teams redesigning the product pages: a net price, identical at every step, with its duration.
- Second research round — sixteen interviews in December 2019, eight Proximus customers and eight who had left for a competitor, to validate the remaining points.
