A plain-English definition of GEO
GEO, or Generative Engine Optimization, is a marketing discipline born in 2024 that focuses on optimising a brand's presence inside the answers produced by generative AI engines. Where SEO earns you a slot in Google's blue links, GEO earns you a place inside the sentence an AI generates to answer your prospect.
Concretely: when a B2B buyer asks ChatGPT "what's the best solution X in Europe?", GEO is the work that makes sure your brand is named, and ideally cited first.
Why GEO matters in 2026
- AI-referred traffic grew +527% year-over-year (source: Similarweb AI search study 2024-2025).
- A visitor arriving from an AI converts on average 4.4× better than a Google visitor (source: Profound, 2025).
- Google's search volume is expected to drop 25% by the end of 2026 due to conversational AIs (source: Gartner, official press release 2024).
- Early-moving brands are building a lead that will be very hard to close.
How do you pick a serious GEO agency?
Four essential criteria for choosing a serious GEO agency:
- 100% GEO specialisation (not a bolt-on to a classic SEO offer).
- A written, measurable methodology with a score out of 100 and monthly tracking.
- Real, demonstrated client case studies, ideally in your sector.
- A real local team that can work in your language and understands the European market.
