01
The shift in layers.
If your client types your sector into ChatGPT today, who comes up? You, or your competitor?
For 25 years, winning on the web meant winning on Google. SEO tuned sites so that Google would rank them among its top ten results. The buying logic followed: a client typed two keywords, scanned a few links, chose, clicked, bought. Everything started with a list.
In 2026, that mechanism is cracking. 30% of searches now begin inside a chatbot: ChatGPT, Claude, Perplexity, Gemini, Copilot, Apple Intelligence, etc. These interfaces don't return ten links: they synthesise a single answer that cites few sources (fewer than 5) before concluding. The other websites and sources no longer exist for that user.
This new layer is the answer layer. It is now where the battle for your visibility is fought. Classic SEO optimises for a layer that is emptying. GEO optimises for the one that is filling up.
In practice, the answer layer decides what the AI retains and restates about your brand or service: the sources it judges reliable, the wording it reuses verbatim, the competitors it cites in your place. You don't enter it through an auction: you settle in by making your content readable, attributable and preferable in the eyes of the engines. Optimising your visibility and citability is precisely what PROEMA does.
02
The first-mover window.
LLMs — Large Language Models — don't learn quickly. Once an AI engine anchors a brand as the authority source for a category, the cost of displacing it becomes prohibitive. For a competitor to take its place, it would have to accumulate a comparable volume of specific signals and the LLMs would have to reindex and reassess its authority.
This inertia is GEO's barrier to entry. Empirically, we observe a defensible head-start window of 18 to 36 months. Today's decisions carry their effects over time. Beyond that, two or three brands settle in and the position stabilises. That window is open for you today. It won't stay open for long.
03
Why our method is defensible.
PROEMA doesn't theorise GEO: we practise and develop it first on our own portfolio of brands before offering it to our clients. We measure the results, we document what works, and we move forward only on what has already proven itself.
The method rests on five levers: a citation audit to establish your starting point, an architecture readable by the engines, editorial production in every language, external authority work, and continuous measurement. Each lever is documented and applied the same way from one project to the next.
This systematisation sets us apart from an agency that delivers slides and walks away: we deliver a complete strategy that can be implemented, measured and defended over time. See our case studies →

Not a consultant. An operator.
PROEMA is a project that grows every day, as a team.
GEO strategy, multilingual editorial production, technical engineering and legal team, measurement: a dedicated skill for each lever of the method.
The approach that defines us: we apply our method to our own assets first, before offering it to our clients.
When we propose a strategy to a client, that approach has already been validated and carried out in practice by a team — not built on an isolated theoretical hunch.
05
Our client commitment.
PROEMA positions itself as a genuine growth partner for its clients, and commits to limiting its portfolio by sector, geography and optimisation level. This approach ensures the satisfaction of our partners, who receive quality services that match our commitments.
Every optimisation engagement starts with a full audit and may be extended by our ongoing support, for a minimum duration of 12 months.
Our promise: to guarantee the rise of your GEO score over time, provided the validated recommendations are implemented within the agreed deadlines, by you or by our team.
To achieve this, we support you end to end: a diagnostic of your current position, implementation of the solutions, ongoing support, and continuous technology and sector monitoring.
We also show you how your competitors operate, where they sit in the answer layer, and how to stand out through GEO optimisation.
Every partner receives a monthly dashboard: GEO score by LLM × language, a wide range of quantitative results, progress against sector competition. The tracking is continuous, not occasional.
