A business owner from Utrecht put two quotes side by side for me last month. One: €2,400 as a one-off for "GEO optimization." The other: €24,000 a year, content not included. Both agencies promised visibility in ChatGPT. Neither document said how many hours would go into it, which pages would be tackled, or how we would measure the result.
That is no coincidence. For SEO there is a rough market rate; for Google Ads the prices are printed in black and white. But for Generative Engine Optimization, transparency is hard to find. Meanwhile, the sums involved are serious. So the question of what GEO costs and what it delivers deserves a concrete answer — with numbers.
What GEO costs in 2026: four pricing models
Nearly every quote I see falls into one of four categories. They differ not just in price, but in what you are actually buying.
1. The one-off technical scan (€750 – €3,500)
Here you get an audit: crawler access, robots.txt, structured data, server-side rendering, Core Web Vitals, entities in your content. An agency spends 8 to 25 hours on it and delivers a report plus a prioritized action list. Useful as a starting point, but it is a one-off. The moment you have read the report, the motion stops. AI answers are reassembled every month; a scan from January says little about what ChatGPT quotes in June.
2. Content retainer (€1,200 – €4,000 per month)
You buy 4 to 10 pieces of content per month, written with AI answers as the goal: clear definitions, direct answers, quotable facts, consistent entities. This model delivers the most for SMBs, provided the content is built on something. Ten blog posts about "the importance of AI" deliver nothing. Three pages that answer a specific question better than every competitor do. How to tell the difference is covered in our GEO strategy for 2026.
3. Full-service GEO retainer (€3,000 – €9,000 per month)
Technical work, content, digital PR, monitoring and monthly course correction. Budget for 30 to 60 hours per month, split across a strategist, a content writer and a technical specialist. This level makes sense once you have more than fifty pages, or once multiple AI platforms (ChatGPT, Perplexity, Gemini, Copilot) matter in your market.
4. Enterprise and multilingual (€8,000 – €25,000+ per month)
Multi-market, multilingual entities, your own measurement environment, coordination with legal and product teams. This often includes reputation management: making sure AI systems summarize your brand correctly, even when negative coverage is circulating.
Why the same service can cost ten times as much
If you compare two quotes that both say "GEO" but differ by 400%, the gap usually comes down to three things.
Hours versus output
An agency that bills by the hour has no incentive to be efficient. An agency that bills per deliverable can accelerate with tooling. Always ask for both the number of hours and the deliverables. A quote without an hours estimate is not a quote, it is a wish.
Technical work, content and distribution are three separate line items
GEO has three parts: making sure AI crawlers can read your site, making sure your content contains answers that can be quoted, and making sure your brand is mentioned elsewhere — news, trade publications, Wikipedia, reviews. Agencies that only do the technical side are cheaper. They also deliver less.
Findable versus recommended
There is a big difference between "ChatGPT mentions my website" and "ChatGPT names me as the recommended choice." The first is technical. The second is positioning, and that is the more expensive work. Five questions to ask a GEO agency before you sign are in our article on choosing a GEO agency.
How to calculate GEO ROI without fooling yourself
Most ROI presentations I see are too good to be true. They multiply an estimated visitor number by a conversion rate and an order value, and call it "projected revenue." That is not a calculation, that is a wish in spreadsheet form.
Do it like this:
Step 1 — What is a customer worth to you? Not the revenue from the first order, but the total margin over the customer relationship. For a B2B service provider with €8,000 in revenue per customer and 35% margin, that is €2,800. For an online store with an €80 average order and 40% margin, that is €32.
Step 2 — How much AI traffic do you get today? Look in your analytics for referral sources such as chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com. For most SMB sites this was under 0.5% of traffic in 2025. For well-optimized sites I see 4 to 9%.
Step 3 — Work with a range, not a single point. Say you have 12,000 organic visitors per month, currently 1% via AI (120 visitors). After a year of GEO work, 4% is realistic (480 visitors). At 2% conversion and €2,800 margin per customer: 7 extra customers per month, €19,600 extra margin. Against a €2,500 per month retainer, that is a multiple of 7.8x — provided the conversion and margin figures hold.
Step 4 — Factor in the ramp-up. The first three months deliver almost nothing. AI models need time to pick up new content and re-weigh your authority. Anyone expecting ROI in the first quarter will be disappointed. Plan on a 9 to 12 month horizon.
Where you are throwing money away
Three expenses I see often and advise clients against:
- Paid "AI mentions" through link networks. Mentions on AI answer aggregators produce short-term noise, not a durable recommendation. As soon as a model figures out the source has no independent value, the citation disappears.
- Content without sources. A piece without concrete numbers, names or data is not quotable for a language model. It exists, but it does not get used.
- Technical work without content. Opening robots.txt to GPTBot is fifteen minutes of work. If that is your entire GEO strategy, you are paying €2,000 for something you could do yourself in an afternoon — we covered that in AEO without a marketing team.
A phased budget: how to split your spend
Months 1-3 — foundation (€2,000 – €5,000 total). Technical audit, crawler access, structured data, rewriting ten core pages with direct answers. Make sure the basics are right before you start producing content; the full list is in the GEO checklist for 2026.
Months 4-9 — volume (€1,500 – €4,000 per month). Two to four new or rewritten pages per month, aimed at concrete questions from your market. Plus three to five external mentions per quarter.
Months 10-12 — measure and shift. Which topics actually earn citations? Which AI platforms send traffic? Stop the half that does nothing, double down on what works. From here you are talking about ongoing budget, not a pilot.
Frequently asked questions
What does GEO cost per month?
For an SMB, a realistic retainer sits between €1,500 and €4,000 per month, excluding one-off technical costs of €1,000 to €3,500. Below €1,000 per month you are usually buying loose content without strategy or measurement. Above €9,000 you are in enterprise territory with multiple markets and languages.
How long before GEO delivers results?
The first citations in AI answers typically appear after 6 to 12 weeks for new, well-structured content. Sustained growth in AI traffic and brand mentions: 6 to 9 months. Models weigh authority and consistency over time; there is no technical trick that speeds that up.
Can I do GEO myself without an agency?
The foundation, yes. Crawler access, structured data, clear answers on your pages and a consistent brand name with fixed entities — that is a few days of work. Sustaining it is the problem: content production, external mentions and monthly monitoring all require continuity.
How do I measure GEO ROI?
Three measurement points: AI referral traffic in your analytics, the number of times your brand is mentioned in AI answers (manually or via monitoring tools), and the conversion rate of that traffic. Without the third measurement, you only know that you are visible, not whether it is paying off.
