TL;DR: a brochure website describes a company; a website that wins clients is built around one measurable action, a call, a quote or a booking. The difference lies in the engineering, not the budget: in 2026, a page built to convert shows a median conversion rate of 6.6% according to Unbounce data, while most brochure websites measure nothing at all.
Many small-business owners ask the same question when they look at a quote: why do two similar-looking websites produce such different results? Because they are not built for the same job. One informs the visitors who happen to find it; the other is engineered to be found, then to turn a visit into a contact request.
- In 2025, 61% of French small and mid-sized businesses had a website according to the Afnic study "Réussir avec le web", down from 70% in 2024.
- A page built to convert shows a median conversion rate of 6.6% across all industries in 2026, according to Unbounce data; below 3%, a page is underperforming.
- On the French market, a professional brochure-style website typically costs €1,500 to €4,500 before tax with an experienced freelancer, and €3,500 to €8,000 with an agency.
- The real decision criterion is not price: it is whether each page of the site targets one specific query and one measurable action.
Two objects that share one name
A brochure website presents the company: who you are, what you offer, how to reach you. A lead-generating website does the same thing, then goes further: every page targets a query a potential client actually types, every block pushes toward one specific action, and everything that happens is tracked. The first is an online leaflet; the second is a sales channel.
The confusion comes from the fact that both look alike. Same polished design, same Home, Services and Contact sections. The difference is invisible on a mockup: it lives in the choice of pages, the wording of headlines, the placement of buttons and the tracking setup. The table below sums up what separates them.
| Criterion | Classic brochure website | Website built for acquisition |
|---|---|---|
| Starting point | What the company wants to say | What the client searches on Google or asks an AI |
| Page structure | Home, About, Services, Contact | One page per offer and per query, plus proof pages |
| Goal per page | Inform | One action: a call, a quote, a booking |
| Measurement | Rarely installed | Visits, sources and conversions tracked from day one |
| After launch | The site never changes | Pages adjusted based on what converts |
Why can a polished website bring in nothing?
Because being online is no longer enough, and the French numbers show it. According to the 2026 observatory of French SMB online presence (source in French), 61% of French small and mid-sized businesses had a website in 2025 per the Afnic study "Réussir avec le web", down from 70% in 2024; the France Num barometer run by the Direction générale des entreprises across more than 11,000 companies measures 64.6%. At the same time, 99% of business owners say the internet is useful or essential, yet 66% spend less than €300 a year on their web presence, as reported by France Num (source in French). Plenty of websites exist; very few are actually managed. Three causes come up again and again.
The pages talk about you, not about what the client is looking for
A contractor who installs heat pumps is not searched as "our craftsmanship"; the query is "heat pump installation cost" followed by a city. If no page on the site answers that query, Google has nothing to rank and AI assistants have nothing to cite. The site is beautiful, and unfindable.
No path leads to contact
On many brochure websites, the only route to contact is a discreet link in the menu. A lead-generating site does the opposite: every page ends with one clear action, a call button, a short form or an online booking, and that action is repeated wherever the visitor makes a decision.
Nobody measures
Without tracking, there is no way to know whether the site pays off, or why it does not. Public reference points do exist: the 2026 benchmarks published by Leadpages, based on Unbounce data, put the median conversion rate of a dedicated page at 6.6% across all industries, with a typical range of 3 to 7% and an underperformance signal below 3%. A site that measures nothing cannot even compare itself to those orders of magnitude.
What makes a website win clients?
Four mechanisms, all checkable from the outside. A site that combines them becomes an acquisition channel; a site with none of them remains a leaflet.
The first is alignment with intent queries: one page per offer, named with the client's words, answering from the very first paragraph. The second is a single goal per page; for call bookings, the same Leadpages benchmarks put expected conversion between 2 and 10% depending on traffic source. The third is proof: real work on display, verifiable numbers, client reviews; a visitor always compares several providers. The fourth is measurement, installed at launch with consent handled properly: traffic sources, page views, conversions, and regular adjustments to whatever converts least.
A fifth mechanism is rising fast: being readable by generative engines. A share of searches now goes through ChatGPT, Perplexity or Google's AI Overviews, and those engines cite pages that answer clearly, with dated facts and named entities. It is specific work, described in my AI visibility test, and it is prepared while the site is built rather than bolted on afterwards.
The site you are reading applies these principles to its own case: pages per query, conversion tracking, content structured to be cited. It is also what I set up for clients as part of website creation projects, with one constant rule: the simplest package that reaches the goal.
So where does price fit in?
The price gap between a brochure and an acquisition website is smaller than the gap in results. On the French market, a professional brochure-style site typically runs from €1,500 to €4,500 before tax with an experienced freelancer and €3,500 to €8,000 with an agency, according to the 2026 ranges compiled by Adekoité (source in French); self-service platforms come to €600 to €900 for the first year, as a recurring subscription. These figures remain orders of magnitude, to be confirmed by quote.
On my side, the pricing is public: a conversion landing page or a simple site starts at €400 before tax with the Sprint package, delivered in one week on a fixed scope; a full site or a redesign is quoted after a 30-minute scoping call. The right way to think about it is total cost over three years, hosting and maintenance included, and above all cost per inbound request: a €4,000 site that generates calls every month is cheaper than a €1,200 site that generates none.
When a simple brochure website is enough
There are cases where the modest brochure is the right call, and it should be said. If your order book is full through word of mouth, an acquisition website will only bring requests you will turn down. If your clients come exclusively through referrals or tenders, the site works as a credibility check, not a sales channel; clear, up-to-date pages are enough. And for a very local business, a well-maintained Google Business Profile sometimes captures most searches before the website even enters the picture.
In those situations, the right spend is minimal: a clean, fast, current brochure with no superfluous subscription. Custom builds and acquisition tooling must be justified by a real commercial goal; when they are not, the budget is better invested elsewhere.
The question to ask is therefore not "how much does a website cost" but "what should this website produce every month". You can run the first diagnosis yourself: count the inbound requests from the last quarter that you can attribute to your site. If the number is zero or unknown, a 30-minute scoping call is enough to identify what is blocking and the simplest package to fix it.
Frequently asked questions
What is the difference between a brochure website and a lead-generating website?
A brochure website presents the company: who you are, what you offer, how to reach you. A lead-generating website starts from the queries your clients actually type, gives every page one measurable goal (a call, a quote, a booking) and tracks conversions from day one. Both can share the same design; what differs is the way they are engineered.
How much does a website that wins clients cost in 2026?
On the French market, a professional brochure-style website typically runs from €1,500 to €4,500 before tax with an experienced freelancer, and €3,500 to €8,000 with an agency. At Mathieu Haye, a conversion landing page or a simple site starts at €400 before tax with the Sprint package; a full site or a redesign is quoted after a 30-minute scoping call.
Can an existing brochure website become a lead-generating one?
Yes, and it is often the best option when the site already ranks on Google. You keep the existing search equity, add pages aligned with client queries, a clear path to contact and conversion tracking. A well-run redesign redirects the old URLs so nothing is lost.
How do I know whether my current website wins clients?
Three checks are enough: do you know how many visits the site gets each month, how many contact requests it generates, and where those requests come from? If the answer is no to all three, the site is not being managed. In 2026, the median conversion rate of a page built to convert is 6.6% according to Unbounce data; without tracking, that number cannot even be checked.
