A GEO agency charges between 1,500 and 12,000 euros per month in 2026, with a median between 2,500 and 5,000 euros for a full engagement. One-off missions, an audit or strategic scoping, range from 1,500 to 8,000 euros. This spread is not commercial vagueness: it reflects radically different scopes. Tracking share of voice on a single AI platform has nothing to do with a multi-platform strategy covering ChatGPT, Perplexity, Gemini and AI Overviews, citable content production and off-site authority work included. The rate depends on three variables: the number of platforms covered, the volume of content produced each month and the billing model. This article details the real ranges of the French market, the levers that push the bill up, the choice between retainer and one-shot, the value of an audit and how to judge a quote before signing.
French market price ranges
A GEO agency charges between 1,500 and 12,000 euros per month in 2026. The median for a genuinely full engagement hovers 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-platform setup, sustained content production and off-site authority work that demands a lot of human time.
One-off missions follow a different logic. A full GEO audit ranges from 1,500 to 8,000 euros as a one-shot. A strategic scoping mission, without execution, runs 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 see why two proposals can differ by a factor of three.
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 a 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 the AI actually cites requires PR, third-party content and time.
A client-rendered site that needs fixing 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. Technical remediation 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 kind of content in series, month after month, is what justifies the upper end of retainers. If you compare two quotes, start by counting the content deliverables, not the rate.
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.
GEO vs SEO: which costs more
At equal scope, GEO and SEO bill in close ranges. The cost difference comes from the nature of the content produced, not from the channel itself.
A classic SEO retainer in France usually sits between 1,500 and 8,000 euros per month depending on competition and production volume. GEO overlaps this range: you find the same tiers, with the upper end pushed by off-site authority work and the demand for citability. The technical base is largely shared: crawlability, server rendering, page structure, markup. That is why many agencies sell both in a single offer, and it is often the most cost-effective choice.
Where GEO genuinely costs more is on content. An SEO article aims for a ranking; a GEO passage aims for a citation, which requires self-sufficient, factual, question-answer structured writing. This format constraint increases expert writing time. If you are weighing the two approaches, or assessing your current provider, our guide on choosing an SEO agency details the criteria that separate a credible partner from a reporting vendor.
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 strategy as results come in. Its drawback: you pay every month, even when progress slows.
The one-shot suits three cases. You first want to map your situation with an audit before committing. You have a content team able to execute 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 | Build share of voice | Scope, audit, start |
In practice, the best entry point combines both: a one-shot audit to scope, then a retainer if you decide to delegate execution. This logic of models also applies to classic search, and we detailed it in our freelance vs SEO agency comparison, useful for arbitrating based on your budget and 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. Below those three deliverables, you are paying for a report, not an audit.
Expect 1,500 to 2,500 euros for a one-off diagnosis 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 prompts, the ones a prospect asks an AI, not your SEO keywords.
An audit's value lies not 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 saves you from funding a retainer blind. It is the most cost-effective investment to enter GEO: it turns an uncertain recurring expense into a prioritized action plan.
A word of caution on low prices. 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 claiming spectacular progress should be read as illustrative: no one controls the AI models, and no serious provider guarantees a number of citations by a fixed date. To go further on what an audit contains and the questions to ask, we have dedicated a full guide to the method and price of the 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 is the quote.
Ask four questions before signing. Which AI platforms do you track? An answer limited to ChatGPT ignores Perplexity, Gemini and AI Overviews, even though 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 missing. 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 building. A twelve-month commitment with no exit clause or review milestone: a quarter is enough to judge the trajectory.
Tooling also matters in what you buy. A credible agency tracks your share of voice with dedicated measurement tools, not by hand. To know which exist and which are worth their price, see our 2026 GEO tools comparison: it helps you verify that the measurement method stated in the quote rests on real data and not on screenshots.
Building a realistic GEO budget
A realistic GEO budget starts from your current situation and your objective, not from a general range. The right method is to size the investment on the volume of content needed to close the gap with your cited competitors.
In concrete terms, think in three stages. First, an audit at 1,500 to 8,000 euros to know your starting share of voice and the ground to make up. Then a retainer sized on production volume: four to six citable passages per month for a niche brand, eight to twelve for a competitive market. Finally, an off-site authority envelope, often underestimated, which represents the most counterintuitive yet most decisive line item for citations.
delay before measurable GEO results
No share of voice is built in four weeks. A realistic budget factors in this delay and does not expect massive citations from month one.
The arbitration rule is simple: never pay a retainer before you have a starting figure. An audit turns an uncertain recurring expense into a prioritized plan, and leaves you free to delegate or execute in-house. If you are still unsure about platform coverage or the combined SEO plus GEO approach, our GEO agency offer integrates measurement, content and authority into 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 lower end covers monitoring and a few optimizations; the higher end includes content production, off-site authority work and multi-platform reporting. The price depends above all on the volume of content produced each month.
Does GEO cost more than SEO?+
At equal scope, the rates are close and the monthly ranges overlap widely. The difference comes from content: GEO requires citable passages and off-site authority work that do not exist in classic SEO. Many agencies sell both together, since they share the same technical base.
Do you need to sign a multi-month commitment for 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 promises 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 work to the agency. Starting with a retainer without an audit means paying before you know where you stand.
How do you know whether a GEO quote is honest?+
An honest quote details the scope of platforms tracked, the number of pages or passages produced each month, the off-site authority work and the share-of-voice measurement method. If it promises a guaranteed number of citations by a fixed date, walk away: no one controls the AI models.
