The agency
We test everything on our own sites before selling it to you.
MACCUS is a cumulative marketing agency. We don’t rent rankings; we build an asset that compounds over time. And we first proved it on our own site, marcwiner.com, which started from zero and now gets 1.3 million visitors per month, 100% organically.

01 · Our story
An agency born from a method, not a sales pitch.
Most agencies sell a method they never apply to themselves. MACCUS does the opposite. Everything we offer a client, we’ve first tested, measured, and made work on our own sites.
We call it cumulative marketing agency: SEO, influence, and organic that add up over time instead of replacing one another. Each month builds on the previous one. After a year, the channel works on its own, and it doesn’t collapse when you cut the ad budget.
It’s this method that took marcwiner.com from zero to 1.3 million visitors per month, without a single euro spent on advertising. Today, we apply it to SMEs, local businesses, and companies that want growth they can see.
No fuss, no fluff: just results. We talk clients, not cosmetic rankings. We show you our numbers, not someone else’s. And if we can’t help you, we’ll tell you.
02 · Our systems
In-house systems, powered by AI.
We built our own systems in-house, powered by AI. They ran on marcwiner.com, our main site, before we offered them to clients.
They handle the repetitive work that can’t be done by hand at scale: translating and localizing content into 23 languages, checking quality language by language, tracking how each version performs, maintaining internal links and technical SEO, and preparing research and first drafts. A person reviews the output and decides what gets published.
You can measure the result on our own site: more than 460,000 sessions a month across 23 languages in September 2026, a figure that grew more than eightfold in a year. The translated versions now bring in close to 40% of the site’s traffic.
The same systems now work for our clients, starting with multilingual SEO. We also set up an AI assistant that takes care of their admin work.
03 · The founder
The proof has a face, and a site you can open.
“Most agencies show you a client’s numbers. We show you ours. They’re harder to fake.”

Three rules, never negotiable.
What doesn’t change, whatever the project or budget.
Proof before promises
We don’t sell you anything we haven’t first proven on our own sites. marcwiner.com’s traffic is public: open it and check for yourself.
Total transparency
Clear monthly reporting, in French, without jargon: rankings, traffic, inbound inquiries. You know what we’re doing, when, and what it should bring in.
Clients, not rankings
A number-one ranking that brings in nothing doesn’t interest us. We optimize for inbound inquiries and revenue, not vanity metrics.
