The offer in detail
Three clear lines:
a landmark, an upkeep, a light.
The site is an object built once — it is paid once. Then three ways to live: keep it maintained without thinking (L’entretien), or make it work for you (Le Feu). Take one, the other, or start with the site alone.

FAQ
Straight answers.
Why a one-time payment plus a subscription, not all-in-one?
Because they are two different things. The site is an object built once: it deserves to be paid once — and to belong to you. Then come two rhythms: L’entretien (€69/month) so nothing breaks, or Le Feu (€190/month) so the site brings you leads. You can take the site alone, or both.
Why a 12-month commitment on the subscription?
Because SEO takes 3 to 6 months to show what it can do. Twelve months is an honest test — and in exchange, the setup fee (€490) is waived. After the first year, the subscription rolls monthly, no fees.
What happens if I stop the subscription?
The site stays online and keeps working — it belongs to you. Two options: keep just L’entretien (€69/month, no commitment) so nothing breaks, or run everything yourself — we then help you migrate the hosting.
What exactly is L’entretien?
The bare necessities that keep your site alive: hosting, domain name, backups, security updates, small changes and support. €69 per month, no commitment. Le Feu does all of that — plus visibility, booking and lead follow-up.
I have no logo, no copy, no photos. A blocker?
No. The guided brief starts with an inventory. For copy, we guide you with simple frames; for photos, a well-framed smartphone shoot is often enough. If needed, we bring in partner photographers (on quote).
What if I don’t know yet what I want?
Start with the diagnostic: six questions, two minutes, and you get an answer with your visibility score and the first three actions — no commitment. If you already know, the guided brief does the rest.
What happens after the 12 months?
Nothing changes except freedom: the subscription becomes monthly and can be cancelled anytime. The price you have stays your price — it does not rise as new features ship.
What is a “contact magnet”?
A quiz or calculator wired into your site: the visitor answers three questions or slides a control, and leaves with a personalised result — in exchange for their email. It’s the tool that turns the curious into contacts, long before they are ready to buy. Designed with you, + €399, once.
Won’t the AI assistant say anything wrong?
No: it only answers from your FAQ, your documents and your published news. If it doesn’t know, it says so and offers to hand over. It introduces itself as an AI, and every contact left in the chat reaches you with the transcript.
Is the newsletter GDPR-compliant?
Yes, by design: signups are confirmed by double opt-in, every email carries one-click unsubscribe, and nothing is sent before confirmation. The welcome sequence (days 0, 2 and 5) only addresses confirmed subscribers.
Unsure about the formula? Start with the brief.
Ten minutes of guided questions, and we answer within 48 h with the right formula — even if it’s “just the site”.
