The price ranges in the French market
A GEO agency charges between 1,500 and 12,000 euros per month in 2026. The median for a genuinely full engagement runs around 2,500 to 5,000 euros per month.
This wide range covers three distinct realities. At the entry level, around 1,500 to 2,500 euros per month, you get share-of-voice monitoring and a few targeted optimizations, often on one or two platforms. In the middle, between 2,500 and 5,000 euros, the agency produces citable content, tracks several AI platforms and works on your technical structure. Above 5,000 euros, you pay for a multi-engine setup, sustained content production and off-site authority work that requires human time.
One-off missions follow a different logic. A full GEO audit sits between 1,500 and 8,000 euros as a one-shot. A strategic scoping mission, without execution, ranges from 2,000 to 6,000 euros. A content overhaul on a defined scope is billed per project, generally between 3,000 and 15,000 euros.
What makes the price vary
The price of a GEO agency depends on four concrete variables. Understanding these levers lets you read a quote and know why two proposals show a threefold gap.
Tracking only ChatGPT costs less than covering ChatGPT, Perplexity, Gemini and AI Overviews. Yet only 11% of cited domains are cited by both ChatGPT and AI Overviews. Covering a single platform means auditing a fraction of the field.
This is the heaviest line item. Producing a self-contained, structured and factual citable passage takes expert time. Four pages per month do not cost the same as twelve. Content often represents half of a retainer.
This is the most counterintuitive and most time-consuming lever. Off-site brand mentions correlate more strongly with AI citations than Domain Rating. Earning mentions on sources that AI actually cites requires press relations, third-party content and time.
A client-rendered site to fix first costs more than a site already in SSR. LLMs do not execute JavaScript: if your content loads client-side, it is invisible to AI crawlers. The technical upgrade inflates the initial quote.
Content volume is by far the dominant factor. Citability cannot be improvised: an optimal citable passage runs between 134 and 167 words, answers a question directly and stands on its own. Producing this type of content in series, month after month, is what justifies the high end of retainers. If you are comparing two quotes, start by counting the content deliverables.
Off-site authority weighs more than your own site. An agency that only bills on-page work ignores the main lever of AI citations, and its low price often hides that gap.
Retainer or one-shot: which model to choose
The choice depends on your GEO maturity and your in-house execution capacity. The retainer suits you if you want to delegate over time; the one-shot suits you if you have a team to execute.
The monthly retainer is the dominant model among GEO agencies, for a simple reason: AI citations do not move in four weeks. Building share of voice requires regular production and authority work that accumulates. A retainer aligns the agency over time and lets you adjust the strategy as results come in. Its downside: you pay every month, even when progress slows.
The one-shot, for its part, suits three cases. You first want to map your situation with an audit before committing. You have a content team capable of executing a roadmap. Or you have a precise, bounded need, such as a content overhaul on a strategic cluster. The one-shot gives you a deliverable and leaves you free.
| Criterion | Monthly retainer | One-shot mission |
|---|---|---|
| Indicative price | 2,500 - 12,000 EUR / month | 1,500 - 15,000 EUR per project |
| Commitment | 3 to 6 months recommended | None after delivery |
| Suits you if | You delegate execution | You execute in-house |
| Content production | Continuous, monthly | Occasional or none |
| Off-site work | Included over time | Rarely covered |
| Best use | Building share of voice | Scoping, auditing, starting |
In practice, the best entry point combines the two: a one-shot audit to scope, then a retainer if you decide to delegate execution. This model logic also applies to classic search, and we detailed it in our comparison of freelance vs SEO agency, useful for deciding based on your budget and your in-house capacity.
What a GEO audit is really worth
A GEO audit is worth its price when it gives you a starting figure, a competitive map and an executable roadmap. Short of these three deliverables, you are paying for a report, not an audit.
Expect 1,500 to 2,500 euros for a one-off diagnostic on a limited scope, and 3,000 to 8,000 euros for a full audit. The difference is measured by the number of queries tested, the number of platforms covered and the depth of the benchmark. A serious audit queries between 30 and 150 real queries, the ones a prospect asks an AI, not your SEO keywords.
The value of an audit does not lie in the final document, but in the decision it enables. A good audit tells you where you are cited, why your competitors are cited more, and which ten to fifteen actions will move the needle. It spares you from funding a retainer blind. It is the most profitable investment for entering GEO: it turns an uncertain recurring expense into a prioritized action plan.
A point of caution on the low price. An audit billed under 1,000 euros is almost always a semi-automated report, with no human analysis or real benchmark. Conversely, a case study that announces spectacular progress should be read as illustrative: no one controls AI models, and no serious provider guarantees a number of citations by a fixed date.
To go further on the exact content of an audit and the questions to ask, we have dedicated a full guide to the method and price of a GEO audit.
How to judge a quote before signing
A good GEO quote is readable: it details the scope, the deliverables and the timelines. If you cannot say what you receive each month by reading the quote, the problem comes from the quote.
Ask four questions before signing. Which AI platforms do you track? An answer limited to ChatGPT ignores Perplexity, Gemini and AI Overviews, when more than 50% of Google queries already trigger an AI Overview. How much content do you produce per month? Demand a number of pages or passages, not a vague formula. Do you work on off-site authority? If the answer is no, the main lever of AI citations is absent. How do you measure my progress? Credible tracking rests on a quantified, reproducible share of voice, not on ChatGPT screenshots.
Be wary of three signals. A promise of quantified results by a fixed date: no one controls the models. A very low price with no content production: you are paying for monitoring, not construction. A twelve-month commitment with no exit clause or review milestone: a quarter is enough to judge the trajectory.
Markup also counts in what you buy. FAQPage schema is a strong signal for AI Overviews, and a good provider integrates it without billing it as a premium option. Likewise, knowing which platform targets your market changes prioritization: our analyses of ChatGPT, Perplexity and Claude show that preferred sources vary widely from one engine to another, which should be reflected in the quote.
To frame your budget starting from your real situation rather than a general range, our 40-point Checklist lets you audit your own fundamentals before requesting a quote. And if you are still hesitating between GEO alone or a combined approach, our SEO agency offering integrates both in a unified visibility logic.

Questions fréquentes
How much does a GEO agency cost per month in 2026?+
Expect between 1,500 and 12,000 euros per month. The median for a full engagement sits between 2,500 and 5,000 euros. The low end covers monitoring and a few optimizations; the high end includes content production, off-site authority work and multi-platform reporting. The price depends mostly on the volume of content produced each month.
Does GEO cost more than SEO?+
At equal scope, the rates are close. The monthly ranges overlap broadly. The difference comes from content: GEO requires citable passages and off-site authority work that does not exist in classic SEO. Many agencies actually sell both together, because they share the same technical foundation.
Do you have to sign a commitment of several months in GEO?+
Serious agencies often ask for three to six months of commitment, and that is legitimate: AI citations do not move in four weeks. Be wary of both extremes: no commitment with a promise of fast results, or a twelve-month commitment with no exit clause. A quarter is a good balance point.
Is a GEO audit alone enough to get started?+
Yes, it is even the best way in. An audit at 1,500 to 8,000 euros gives you your starting share of voice, a competitive benchmark and a prioritized roadmap. You can then execute in-house or hand the engagement to the agency. Starting with a retainer without an audit means paying before you know where you stand.
