GEO agencies in Spain: who does what and how to choose in 2026

GEO stopped being an exotic label: by 2026 Spain has a real market of agencies selling presence inside the answers of ChatGPT, Perplexity, Gemini, and Google AI Overviews. This guide names the visible players — including our competitors, because that is the content standard we argue for — and ends with the checklist that actually separates a specialist from an SEO shop with a new landing page.

Disclosure first: Citable (citable.agency) is one of the agencies listed. Every company below is described using its own public positioning, with no editorializing from us.

Who’s who, in their own words

• Dobuss — a digital agency positioning itself as a reference GEO agency in Spain, with GEO as the evolution of its SEO practice.
• Ventia Group (Barcelona) — describes itself as GEO experts who help clients be “actively recommended by artificial intelligence,” not merely found.
• Javadex (Vigo) — a consultancy reporting, on its own blog, that claude.ai overtook google.com as its number-one qualified-lead channel in January 2026 — rare first-hand data in this sector.
• geoagencia.com — positions the GEO audit + monthly execution formula, focused on citability, entity, and prompt tracking.
• Coco Solution (Las Palmas) — positions itself as GEO specialists for ChatGPT, Perplexity, Gemini, and Claude and the first GEO agency in the Canary Islands, claiming 30+ brands positioned and clients across Spain, Latin America, the US, and the UK.
• InboundCycle (Barcelona) — a veteran inbound agency (since 2011) offering GEO/AEO under the promise of making “your brand the answer” when your customers ask AI, with offices in Madrid and Latin America as well.
• Hostino — defines itself as a GEO agency in Spain specialized in optimizing brand visibility inside AI-generated answers, with service pages for 30+ Spanish cities.
• Summum Marketing (Castilla y León and the Canary Islands) — folded GEO into its standard service in 2025: an AI-visibility audit across ChatGPT, Perplexity, and Gemini, a quarterly citable-passages plan, and monthly citation measurement, with an SME focus.
• Citable (citable.agency) — us: a boutique agency founded in Spain in 2026, native bilingual EN/ES, with a published methodology (the CITE Framework), a free 10-signal checker, and published pricing with no discovery-call gate.

If a name is missing that should be here, tell us — we update the list under the same rule: public positioning only, nothing invented.

The selection checklist

1. A measurable baseline. Without a documented Share of Answer baseline — prompts, engines, dates, scores — six months from now “it’s working” will be an opinion.
2. Published pricing and scopes. Serious GEO can be productized. If everything needs a call to learn the price, the scope will be negotiable later too.
3. Native bilingual if you leave Spain. Entity signals must exist in the prompt’s language; translated content gets cited less than natively written content.
4. Real technical depth. Ask about schema, entity disambiguation in Wikidata/Knowledge Graph, and extractability — if the answer is just “AI-optimized content,” keep looking.
5. Who executes. A report without implementation is an expensive PDF. Demand that every delta in the monthly report be attributable to a shipped change.

And the sector’s acid test: ask the agency for its own citations. Prompt ChatGPT or Perplexity for GEO agencies in Spain and see who shows up — this is the only industry where the product audits itself in every answer.
