French GEO Agency: make your brand visible and cited by generative AI
Get your brand cited in ChatGPT, Gemini and generative search engines with NOIISE
What is GEO? GEO (Generative Engine Optimization) is the optimization of a brand’s presence in the answers written by generative AI, so that it is cited, mentioned or recommended.
By combining SEO and GEO, we optimize your content so it becomes a source that is understood, selected and cited by AI engines such as ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews.
Our work received the GEO Special Prize at the SEMY Awards 2026, presented at SMX Paris, in the first edition to include a GEO category.

The NOIISE methodology: your GEO roadmap
Our GEO support follows three steps: audit, deployment, measurement.
Step 1: Conversational visibility audit
The GEO audit diagnoses your brand’s AI footprint. We run it with Acoustiik, which identifies the sources cited by ChatGPT, Gemini and Perplexity and measures your AI-Citation Rate: how often your brand is cited across a large number of queries.
We start from the questions your customers actually ask ChatGPT, for example “Which payroll software should a small business choose?” or “Which agency should I hire to rebuild an e-commerce site?”.
- Analysis of ChatGPT, Gemini and Perplexity answers on your key topics
- Mapping of cited sources and visible competitors
- Assessment of the consistency and readability of your content for LLMs
Your deliverables: your AI-Citation Rate, the citation map, the list of obstacles and opportunities, and a prioritized GEO roadmap.
Step 2: Technical and semantic deployment
- Analysis of query fan-out (the sub-queries an AI generates from a question to compose its answer) and of search intent
- Structuring and optimizing content for AI engines (chunking, microdata…): chunking splits content into self-contained blocks an AI can extract on their own, and microdata tag the code to tell engines what each piece of information is
- Semantic and intent alignment of strategic pages
- Reinforcement of credibility and legitimacy signals (E-E-A-T: experience, expertise, authoritativeness and trustworthiness, Google’s quality criteria)
- Advice on off-site visibility and external mentions (link building, backlinks, PR…)
Step 3: Measure the impact with Acoustiik
GEO performance rests on one key indicator: the probability that a brand is cited, reused and mentioned in LLM answers.
Acoustiik, our proprietary tool, tracks this visibility over time. It gives your LLM share of voice: where your brand stands against your competitors.

EFLC 👩🎓Our levers to maximize your citability
A GEO agency does not act only on a site’s content. It works on every signal AI uses to understand, select and cite a brand. Our citability strategy rests on five levers.
Structure your content and add structured data
We split your pages into self-contained blocks (chunking) and add structured data (microdata) so AI can extract information without ambiguity.
Align your pages with real user prompts
We analyze how your customers phrase their questions to ChatGPT, Gemini or Claude, as well as the derived sub-queries AI generates (query fan-out). Each strategic page then answers one precise prompt, in natural language.
Harmonize your brand messaging
We align your messages, vocabulary and public statements from page to page. A consistent brand is better understood, and judged more reliable, by AI engines.
Strengthen your brand authority
We consolidate the expertise and legitimacy signals (E-E-A-T) of your site and guide your off-site visibility. AI engines readily favor recognized sources.
Optimize technically for LLM crawlers
A page can only be cited if AI crawlers can explore it, read its markup and extract its text. Our AI visibility audit assesses this readability and identifies the obstacles to remove first.
The goal is not to appear occasionally but durably: to establish your brand as a trusted source in AI answers, well beyond a simple SEO ranking.
Strengthen your brand authority beyond your site
Generative AI does not rely only on your site: it cross-checks third-party sources (media, forums, social networks, reviews, comparison sites) to decide which brands to cite. Building off-site authority and mentions is therefore an integral part of a GEO strategy.
We start from the sources identified during the audit: those ChatGPT, Gemini and Perplexity already cite on your queries, and those that make your competitors appear. The point is not to accumulate links, but to make your name and expertise exist where AI goes looking for answers.
Each action targets a source identified in the audit: you know why it is carried out and which AI answers it should influence. In a saturated market, effort goes where the citation is decided.
- Link building and backlinks: links from authoritative sites in your sector, first those AI engines consult. See our link building agency offer.
- Press relations: articles and media coverage that AI cross-checks to judge a brand’s legitimacy. See our press relations.
- YouTube, Facebook, Instagram, LinkedIn…: citations in discussions, expert posts and videos, where AI looks for real user opinions.
- Reviews and comparison sites: up-to-date customer reviews and accurate listings on the comparison sites AI relies on to recommend a product or provider.
Why GEO is becoming essential for brands
Generative AI is already part of everyday life. According to the 2025 Digital Barometer (Arcep, Arcom, CGE, ANCT), 48% of the French population uses generative AI services, rising to 85% of 18-24 year-olds and 78% of managers and professionals.
These tools are used first to look up information (73%), then for writing and translation help (58%) and for finding new ideas (57%). AI is becoming an entry point to information, like a search engine.
For a brand, ranking well on Google is no longer enough. Generative engines answer with a synthesis, not a list of links: your visibility depends on the sources they retain. GEO aims to make your brand one of those sources.
The strategic benefits
- Be cited and recommended by AI engines on strategic queries
- Strengthen credibility and brand authority
- Influence decisions from the conversational search phase
- Get ahead of competitors still absent from AI answers
- Complement and reinforce SEO on complex, high-value queries
How do LLMs choose their sources?
A generative AI cites the sources it understands easily, can cross-check with others and judges reliable. AI vendors do not publish their criteria: the markers below come from analysis findings, not official rules.
| Dimension analyzed by AI | Impact on citation probability |
|---|---|
| Understanding of named entities | Lets the AI link the content to the topic of the prompt and judge its relevance |
| Information structure | Makes data easier to extract, summarize and reuse |
| Structured data | Explicitly describes the brand, its offers or its FAQ, helping AI crawlers interpret the page |
| Editorial consistency | Strengthens the perceived reliability of content over time |
| Legitimacy and authority | Directly influences selection as a reference source |
GEO is not simply about making a site visible. The challenge is for a brand to be understood, judged reliable and selected by AI engines at the moment they build their answers. At NOIISE we treat this citability as a strategic lever in its own right, combining content structure, editorial consistency, brand legitimacy and analysis of the sources LLMs actually use.

The CURL model: NOIISE’s strategic signature
CURL is the proprietary framework on which NOIISE builds every GEO strategy. These are not criteria published by AI vendors: the framework organizes how we read their answers.
CURL is the foundation of our audits to spot the citability levers to activate first.
- C – Consistent: content and messages aligned semantically and editorially help AI understand the brand.
- U – Unique: AI engines would favor a source with a distinct point of view or identifiable expertise over generic content.
- R – Regular: a brand that publishes and updates content over time appears more reliable to AI.
- L – Legitimate: expertise, external recognition and source credibility would weigh heavily in the decision to cite a brand.
GEO agency, freelancer or in-house team: which to choose?
A GEO agency brings together skills rarely found in a freelancer or an in-house team: SEO, GEO, SEA, content and permanent monitoring of AI engines. Since 1999, through the merger of major web players, our agency has gathered consultants from all these disciplines to run large-scale projects over the long term.
On a complex e-commerce site, a GEO agency must frame its technical recommendations and validate them with your teams before any deployment. Our GEO support then steers your strategy with citation indicators measured in Acoustiik, so you can justify each action to your management.
