6 Best GEO Agencies in Spain (2026)

SEOCOM publishes a full GEO service page with named deliverables including a generative engine presence audit, semantic optimization for LLMs, entity schema markup and monthly mention monitoring. It also publishes starting prices, which most Spanish agencies do not.

You want a large, search-specialist team that treats AI visibility as a formal service line rather than an add-on.

• Operating since 2008 with more than 30 in-house staff across two Spanish offices
• Dedicated GEO page listing six concrete deliverables, not a generic AI mention
• Publishes entry pricing openly on its own site

• Scope is deliberately narrow, so paid media, conversion work and development need separate vendors
• No answer engine terminology is used, so buyers looking specifically for AEO framing will not find it here

Its AI search page lists specific deliverables such as analysis of content cited by LLMs, detection of queries affected by AI Overviews, creation of new citable assets, and dashboards measuring mentions and authority signals inside generative engines.

You want one team handling acquisition and conversion together, with AI search folded into the SEO program.

• More than 30 professionals spanning SEO, paid media, conversion, analytics and development
• Publishes a 30-day senior-led AI SEO audit with a defined scope
• Registered Spanish company with a verifiable Barcelona address

• Only one Clutch review backs the 5.0 rating, so third-party validation is thin
• The agency does not publish pricing, so budget fit requires a call

Its GEO page names four concrete workstreams: a generative citation audit, a citable content strategy built on experience and authority signals, authority work on the link profile and Knowledge Graph, and ongoing chatbot monitoring.

You want a mid-sized Spanish team that pairs classic SEO and paid media with an explicitly defined LLM visibility process.

• Fourteen years operating in Barcelona with a named 24-person specialist team
• GEO offering documented with audit, content, authority and monitoring stages
• Offers a complimentary generative visibility audit with a stated 24 business hour response

• No pricing is published, and the free audit is the main entry point
• Only two Clutch reviews support the rating, a small sample for a 14-year-old agency

Every core service on its own site is labelled SEO and GEO, including comprehensive audits, technical work, on-page, international and local, which shows AI search is integrated rather than bolted on. The site lists clients including Iberia, El Pais and Reale Seguros, and the team published the first SEO book in Spanish in 2006.

You run a large or multilingual site and need deep technical SEO experience with migrations and international rollouts.

• Operating since 2001, one of the longest-running SEO firms in Spain
• Around thirty consultants with published enterprise clients such as Iberia and El Pais
• Authored eleven industry books, including the first Spanish-language SEO title

• No pricing or project minimum is published anywhere on the site
• GEO is layered into existing SEO services rather than sold standalone, which suits integrated buyers more

Its own site markets positioning in AI engines, stating it adapts brands to be visible and relevant in generative engines such as ChatGPT, Gemini and Perplexity, optimizing content and site structure so AI understands, cites and recommends the brand.

You need search, paid media and influencer work coordinated by one Madrid agency with a transatlantic footprint.

• Madrid headquarters plus a Miami office for Spanish and US market work
• Broadest service mix of the six, covering influencer marketing as well as search
• Founder is a recognised public voice in the Spanish search industry

• Search is one line among many, so specialist depth may be thinner than at search-only shops
• Its Clutch profile carries no client reviews, so independent validation is limited

It is the only agency of the six to name answer engine and generative engine optimization as separate, productised components alongside technical SEO, and it documents an AEO method covering scannable 40 to 60 word blocks, intent matching, trust signals and recency. Pricing is published openly with no lock-in.

You want a fixed-price monthly AEO and GEO retainer with transparent scope rather than a custom enterprise proposal.

• Publishes monthly pricing and a no-permanence contract policy on its own site
• Explicitly separates AEO and GEO as distinct disciplines with documented methods
• Offers a free GEO audit as a low-commitment entry point

• No founding year, team size or client list is published, so track record is harder to assess
• The offering bundles AI sales automation with search, so search-only buyers may pay for adjacent tooling
