GEO agency: getting your company cited by ChatGPT, Perplexity and Google AI Overviews
Generative engine optimization for biotech, medtech, deeptech and technical industries
- AI visibility audit on 20 to 40 questions your prospects ask
- Entity, structured data and citable content
- Scientific writers with MD and PhD backgrounds
- Monthly tracking of citations with the AI Marketing Studio
Your prospects no longer search only on Google: they ask ChatGPT, Perplexity or Gemini which companies exist in your category, which ones are credible, and who to write to. A GEO agency (generative engine optimization) works so that the answer names you, describes you correctly and points to your pages.
DigiObs applies GEO to scientific and technical companies: we know your audiences, your regulatory constraints and how answer engines handle health and technology topics. The result is measured every month, as the share of AI answers in which you appear, and adds up with your Google rankings.

Why a GEO agency, and why now
The demand is there. In France, "geo seo" is searched 2,900 times a month, "agence geo" 1,600 times, "generative engine optimization" 880 times and "référencement ia" 390 times (DataForSEO, August 2026). Companies have understood that their visibility now also plays out in written answers, not only in a list of links.
In scientific sectors the topic is even more sensitive: assistants are cautious on health and technology, and only cite clear, identified and consistent sources. A biotech, a medtech or an instrument maker that has not worked on its entity and its content is simply absent from the answer, whatever the quality of its science.
What a GEO agency does
AI visibility audit: we ask the answer engines the questions your prospects ask, record who is cited, with which sources, and where you stand.
Clear entity: explicit About and service pages, Organization, Service and Person structured data, an llms.txt file, consistent information on LinkedIn, Google Business Profile and sector directories.
Citable content: pages that answer one precise question, sharp definitions, structured FAQs, sourced data, detailed case studies, written by scientific profiles.
Corroboration: visible partnerships, mentions in the ecosystem (clusters, trade press, clients), reviews and testimonials that confirm what your pages say.
Integrated SEO: one content plan serves both Google rankings and AI citations, with one dashboard.
Monthly measurement: share of voice in ChatGPT, Perplexity, Gemini and Google AI Overviews, dominant sources, cited pages, actions for the following month.
Where do you stand in ChatGPT and Perplexity?
An audit on the questions your prospects ask shows who is cited instead of you and which pages are missing. Describe your market: we will propose the scope and the budget.
Our method in five steps
- Scope: a set of 20 to 40 questions representative of your market (category, problem, comparison, purchase), in French and in English if you sell internationally.
- Audit: each question is put to the selected engines, the answers are read and classified: cited or not, how, from which sources. You get a baseline share of voice and the list of missing pages.
- Build the entity: we correct and complete your identity pages, structured data, llms.txt file and external listings so that engines describe your company without error.
- Produce the content: answer pages, guides, FAQs and case studies written by our scientific writers, reviewed by your experts, published with the right markup.
- Measure and iterate: every month the share of voice is recorded, the dominant sources analysed, the plan adjusted. Results are read in the AI Marketing Studio, next to your Google rankings and traffic.
Deliverables and rhythm
Audit report: share of voice per engine and per theme, sources cited instead of you, missing pages, prioritised action plan.
Entity sheet: reference description of the company, structured data ready to publish, llms.txt, list of external listings to align.
Content calendar: topics, targeted questions, format, author, date, with briefs and scientific reviews.
Monthly dashboard: AI citations, Google rankings, traffic and leads on one screen, with a thirty-minute monthly review.
Who it is for
Our GEO clients are companies with a technical offer whose buyers research at length before contacting a supplier: biotechs and CROs, medtechs and medical devices, deeptechs, instrument and consumable manufacturers, niche industrial players. We also work for firms and organisations that sell scientific expertise.
If your prospects ask an AI assistant questions before writing to you, GEO concerns you. If your sector is regulated, it concerns you even more: engines select their sources there with extra care.
Pricing and commitment
The audit and the monthly tracking are quoted according to the number of questions tracked, engines, languages and pages to produce. The first thirty-minute call scopes the work and gives you a precise idea of the budget before any commitment.
You stay in control: the content is published on your site, the structured data and the llms.txt file belong to you, and the dashboard remains accessible to your team.
GEO and SEO: one plan, two results
Content designed to be cited by an AI is also content that ranks on Google: direct answer, clear structure, sources, identified expertise. So we do not separate the two. SEO brings measurable traffic, GEO brings presence in answers; both are read in the same dashboard.

Frequently asked questions
What is a GEO agency?
A GEO agency (generative engine optimization) works on a company's visibility in the answers of AI assistants: ChatGPT, Perplexity, Gemini, Google AI Overviews. It audits who is cited, clarifies the company's entity, produces citable content, organises external corroboration and measures every month the share of answers in which the company appears.
How is it different from an SEO agency?
SEO aims at a position in a list of results, GEO at a place in a written answer. The fundamentals are shared (useful content, expertise, structured data, authority), but GEO adds entity work, citable phrasing and corroboration, and is measured differently: as share of voice in AI answers rather than as a ranking. DigiObs handles both in a single plan.
How long before ChatGPT cites us?
The first citations generally appear one to three months after the content is published and the entity made consistent, depending on the competition on your questions and how often the indexes refresh. Answer engines that rely on live search (Perplexity, Google AI Overviews) react faster than those that depend on a trained index.
Can AI citations be measured?
Yes. Every month we put the same set of questions to the same engines, record whether you are cited, with which wording and from which source, and compute a share of voice per theme. This tracking is presented in the AI Marketing Studio, next to your Google rankings and your traffic.
Do we need to produce a lot of content?
No, you need to produce the right content. An audit usually shows that about ten precise pages (answers to category questions, comparisons, case studies, definitions) cover most of the useful queries. The quality and clarity of the sources matter more than volume.
Is it suitable for a regulated sector, healthcare or medical devices?
Yes, provided the framework is respected: no unsubstantiated claim, exact regulatory vocabulary, review by your experts. Answer engines precisely favour cautious, sourced material on these topics. Our MD and PhD writers work with these constraints every day.
