03AI search optimisation (GEO)

GEO: get cited by ChatGPT, Perplexity, Gemini and Google AI Overviews.

What is GEO?

GEO (Generative Engine Optimization), or AI search optimisation, aims to get ChatGPT, Perplexity, Gemini or Google AI Overviews to cite your company when a client asks them for a provider.

These assistants rely on your website and on what other sources say about you. So we work on both.

What we actually do

See the details (4)

  • A website that is easy to understand

    Your services, prices and areas presented clearly, with structured data that Google and AI assistants read without ambiguity.

  • The same details everywhere

    The same name, address and description on your website, your Google profile and directories: AI assistants identify you without mistakes.

  • Answers ready to be cited

    Definitions, prices, timelines and FAQs written so an AI assistant can reuse them and cite your name.

  • Monthly tracking

    We put your clients' questions to ChatGPT, Perplexity and Google, and show you whether you are cited.

SEO vs GEO: what is the difference?

GEO does not replace SEO, it builds on it: AI assistants draw mostly on pages that rank well on Google. What changes is the goal: being cited in an answer, rather than ranked in a list of links.

06Local SEO

SEO in Les Sables-d'Olonne and the Vendée region

Based in Les Sables-d'Olonne (85100), Agence Zen helps Vendée businesses get found by clients nearby: shops, firms, tradespeople, independent professionals and tourism businesses.

In the Vendée, from Les Sables-d'Olonne to La Roche-sur-Yon, Challans or Saint-Gilles-Croix-de-Vie, local SEO rests on four things: a complete and active Google profile, regular customer reviews, service pages that name the towns served and identical contact details across directories.

We also work with companies across France, in Switzerland and in Canada. Everything happens by video call, with the same point of contact from the first call to the monthly report.

07Frequently asked questions

SEO, GEO and Google Ads: your questions.

How much does an SEO programme cost?

SEO & GEO costs €790/month (Visibilité), €1,490/month (Autorité) or €2,900/month (Leadership). Month one is dedicated to the audit and the action plan. 6-month commitment, then month to month. A standalone audit costs €690.

How long does SEO take to show results?

The first effects often appear after 2 to 3 months, especially locally. Clear results usually take 6 to 12 months, depending on competition and the website's history. Hence the initial 6-month commitment.

Can you guarantee first place on Google?

No, and no agency can honestly guarantee it: neither Google nor AI assistants sell their organic results. We commit to a method, a defined volume of work in each package and a transparent monthly report.

What is GEO, or AI search optimisation?

GEO (Generative Engine Optimization) aims to get your company cited in the answers of ChatGPT, Perplexity, Gemini or Google AI Overviews. It relies on a clear website, consistent details everywhere and content that is easy to cite. It complements SEO rather than replacing it.

How much does Google Ads management cost?

Our fees are €790/month (Lancement), €1,490/month (Performance) and from €2,900/month (Scale). The ad budget is paid on top, directly to Google: we recommend at least €1,500 per month.

Do I need a new website to improve my SEO?

Not necessarily. The audit shows whether your current website can improve or whether its speed or structure is holding it back. In that case, a redesign may pay off: our websites include SEO and GEO foundations from the design stage.
