Quick answer: An AEO/GEO agency gets your brand cited and recommended by AI answer engines — ChatGPT, Perplexity, Google AI Overviews and Gemini. It runs AI-visibility audits, restructures content into answer-ready form, builds entity and authority signals, fixes the technical and schema layer, measures citations per engine, and keeps classic SEO running alongside — because the indexes AI retrieves from are still Google’s and Bing’s. Typical European retainers run from about €800 to €6,000+ per month.
Why this role exists now
Search behaviour has split. Roughly 68% of US searches now end without a click, and Google AI Overviews appear on more than 20% of queries. Buyers increasingly get their shortlist from an AI answer, not a page of blue links. If the AI doesn’t mention you, you’re not on the list. A generative-engine-optimization agency exists to make sure you are — to turn “invisible to the AI” into “the source it quotes.”
The six things a real AEO/GEO agency does
1. AI-visibility audit. The starting point is a map of where you are — and aren’t — cited today across ChatGPT, Perplexity, Gemini and AI Overviews, for the prompts your buyers actually type, in each language you sell in. Good agencies benchmark your share of voice against named competitors, not just your own history.
2. Answer-ready content. Engines lift passages they can quote without editing. The agency restructures key pages into direct ~50-word answers, FAQ-style chunks and clear headings so a machine can extract a clean unit. This is editorial work, not keyword stuffing — it improves the page for humans too.
3. Entity and authority building. AI engines favour brands they recognise as entities and sites they trust on a topic. That means digital PR, earning mentions and citations on independent sites, a consistent brand and author identity, and a genuine presence where engines look — Reddit and YouTube together supply about 78% of the social sources AI cites. Higher-authority domains are cited far more often.
4. Technical and schema layer. Clean semantic HTML, Article and FAQPage structured data that matches the visible text, crawlability for AI crawlers, and fast, accessible pages. Google’s John Mueller notes clean semantic HTML can be enough on its own — but matching schema measurably improves the odds.
5. Cross-engine measurement. Because each engine retrieves differently — AI Overviews from Google’s index, ChatGPT and Copilot via Bing, Perplexity via its own crawler — the agency tracks citations and share of voice per engine and per language, and reports what’s actually being quoted, not vanity rankings.
6. SEO alongside GEO. The indexes generative engines pull from are still the classic search indexes. Strong traditional rankings, links and technical health remain the feedstock for AI citations. The best agencies in 2026 do both; anyone selling “GEO instead of SEO” misunderstands the plumbing.
What it costs across Europe
GEO/AEO pricing tracks local SEO-agency economics, so localise — never convert £ to € or assume one rate fits the continent. As a 2026 guide, monthly retainers typically fall in these ranges:
| Market | Typical monthly retainer | Notes |
|---|---|---|
| Germany (DE) | €1,500 – €6,000 | Freelancers ~€80–€150/hr |
| France (FR) | €1,000 – €5,000 | Agencies higher in Paris |
| Spain (ES) | €800 – €3,500 | Wide freelance market |
| Italy (IT) | €800 – €3,500 | Milan at the top end |
| Netherlands (NL) | €1,500 – €5,000 | Strong technical talent |
| Poland (PL) | 4,000 – 15,000 zł | Strong value for spend |
| UK (EN) | £1,000 – £5,000 | Median retainer ~£3,500 |
Entry GEO-focused engagements at international agencies often start around €4,000/month. Project or audit-only work costs less; ongoing authority-building costs more. Beware anyone quoting a single flat number without seeing your market and languages.
How to tell a real AEO/GEO agency from repackaged SEO
Ask four questions. *Can you show me where I’m cited today, per engine and per language?* (If they can’t measure it, they can’t move it.) *What’s your plan for entity and authority, not just on-page tweaks?* *How do you handle each language natively?* — a translated page rarely earns local citations. *And how do you keep classic SEO running?* A credible answer to all four separates a genuine practice from a rebranded audit template.
The EU layer buyers should check
A European AEO/GEO engagement isn’t just marketing. Ask how the agency handles the EU AI Act transparency phase-in (2025–2026) for AI-generated content, GDPR for any data or lead handling, and the European Accessibility Act (WCAG 2.1 AA, in force June 2025) for the pages they’ll touch. A partner who can’t speak to these is a compliance risk, not just a marketing one.
FAQ
Is GEO just SEO with a new name? No — it overlaps but adds citation strategy, entity building and cross-engine measurement. But it fails without an SEO foundation.
How fast are results? Answer-ready pages can be cited within weeks once indexed; authority and entity work compounds over months.
Do I need a specialist agency or can my SEO team do it? A capable SEO team can adopt GEO with the right measurement tools; a specialist accelerates it, especially across multiple languages.
Can you guarantee citations? No honest agency guarantees a citation — engines change constantly. They can guarantee the process and report measurable share-of-voice gains.
