Best GEO agency 2026: the ranking, the methods and how to spot pretenders
Six GEO agencies ranked for 2026: methods, tracking tools and prices per their own sites. Plus five labels that expose GEO pretenders in ten minutes.
If you search for the best GEO agency, what you mostly find are GEO pages. Almost every SEO agency has added one in the past twelve months. Some describe real work on mentions in ChatGPT, Perplexity and Google AI Overviews. The rest is the old on-page package with a new label. So there is no single best GEO agency, but there are three questions that reliably sort out the pretenders.
This ranking sorts six providers, whose GEO pages we read on 9 September 2026, by exactly those questions: Is visibility measured against a fixed prompt set? Is the work tied to the website structure? Are prices on the page? After that, five labels that give away GEO pretenders, and what a retainer realistically costs.
Key takeaways
- INSYNC is number 1 because GEO here is tied to the engineering rather than to a consulting PDF: server-rendered HTML for AI crawlers, schema, llms.txt and an entity home, measured through Peec AI and Ahrefs Brand Radar. Audit from a fixed 1,500 euros.
- Claneo (Berlin, 80+ experts) and Peak Ace (Berlin, 170+ staff) are the strongest choice for enterprise budgets that combine digital PR with a dedicated monitoring setup.
- Only three of the six providers publish prices: INSYNC (audit from 1,500 euros), Aufgesang (minimum budget 1,000 euros net per month) and suxeedo (from around 3,000 euros per month).
- The sharpest pretender test: whoever does not measure mentions and citations across a fixed prompt set cannot show you any change after three months.
- First citations realistically take three to six months. Anyone guaranteeing you mentions in ChatGPT is promising something not even OpenAI can commit to.
GEO in three sentences
Generative Engine Optimization makes sure ChatGPT, Perplexity, Gemini and Google AI Overviews name your company or cite it as a source when someone asks about your service. In SEO your website is the stage; in GEO it is one source among many, because models cite directories, trade media, reviews and third-party comparison articles just as readily. That is why GEO measures mentions, citations and share of voice per prompt instead of rankings, and why it is not SEO with a new label.
The 2026 ranking
The order follows four questions you can put to any GEO page: is GEO core business or an add-on? Is visibility measured across a fixed prompt set, with named tools? Is the work tied to website structure, or does it end in a consulting PDF? Are prices on the page?
For the other five, we only repeat what their own websites say as of 9 September 2026. And for each one there is a note on the case it fits. Claneo, Peak Ace and Aufgesang are larger, with more digital PR reach and more corporate references. Our lever is a different one: GEO sits directly on the website here, because we rebuild it ourselves instead of handing recommendations to another team.
1. INSYNC
INSYNC works out of the Upper Palatinate with an international team and more than 250 delivered projects. GEO here is not a second service page, it is tied to the engineering: AI crawlers render no JavaScript, so we build websites server-rendered from the ground up, with clean semantics, schema, llms.txt and an entity home connected to Wikidata. The other five are search agencies and deliver recommendations. We build the site those recommendations depend on ourselves.
On content we work from our own playbook, distilled from tens of thousands of analysed data points, studies and live tests: query fan-out instead of a single keyword, question and answer structure, definition blocks, comparison content and RAG-ready chunking. Production runs through an AI-supported pipeline with a quality gate, which is why the monthly deliverables are fixed numbers rather than vague support.
Measurement runs through Peec AI and Ahrefs Brand Radar: share of model, citation rate, sentiment and mention context across a fixed prompt set, reported monthly in plain language. Prices are public on the GEO agency page: audit from a fixed 1,500 euros, ongoing support from 1,790 euros a month. Visibility is only half the job: we also build the pages visitors from AI answers land on and optimise them for enquiries. Right for B2B companies that want GEO, website structure and conversion tackled together.
2. Claneo
Claneo is based in Berlin, has worked with 80+ experts since 2017 and calls itself an "SEO and GEO agency from the very first hour". Its GEO modules per the website: AI Quick Check, AI visibility monitoring, log file analysis for AI bots, E-E-A-T audits and digital PR. On top comes something nobody else on this list has: its own GEO conference, "GEO KNOW HOW" on 1 October 2026, and a GEO textbook. The GEO references on the site are Zattoo, HUK24 and Bike24. Prices: on request. Right for enterprise companies with budget for digital PR and continuous monitoring that want GEO embedded in a broad search strategy.
3. Peak Ace
Peak Ace is a Berlin AG with 170+ staff, part of the Heroiks Group, and calls its approach "data-first GEO". The offer per the website: AI visibility checks with mention rate, citation rate and share of voice, prompt set creation and LLM consulting. Peec AI is the default tracking tool, with Profound or Rankscale as alternatives, plus an in-house GA4 dashboard for LLM traffic. An agency whitepaper puts the share of citations coming from earned media at 82 percent, a figure Peak Ace collected itself. The GEO page names neither GEO clients nor prices. Right for large brands that run digital PR as their GEO lever and need a measurement setup at corporate scale.
4. Aufgesang
Aufgesang is based in Hanover, has operated since 1998 and has belonged to the Heise Medien Group since 2021, with 45 to 50 staff. The agency describes itself as a GEO pioneer since 2023, with Olaf Kopp leading the area as Head of SEO & AI Search. Its own concepts are called "LLM readability optimization" and "digital authority management", and a free LLM readability check sits on the site. Clients per the website: Rossmann, Tamaris, Heise Online, Warner Music. One of the few to state a minimum budget: 1,000 euros net per month. Right for companies that want methodical depth and thought leadership and prefer a team that publishes its concepts openly.
5. suxeedo
suxeedo is based in Berlin, founded in 2011, with 40+ experts, and sells GEO as LLMO in a fixed four-phase plan: audit in weeks 1 and 2, strategy in weeks 3 to 6, setup in months 2 to 4, monitoring from month 4. Its KPIs are answer inclusion rate and share of answer. Tracking per the website runs on Otterly, Peec AI and an in-house AI Search Visibility Dashboard. Cases on the site: WOLF, Selfmade Energy, Théa Pharma. Prices: from around 3,000 euros per month. Right for content-heavy companies that want a phased plan with dates and build GEO through editorial content.
6. Semtrix
Semtrix is based in Düsseldorf, founded in 2015, part of the Eskimoz Group since 2024, with around 40 experts in Germany. GEO is run as a standalone discipline, with an in-house GEO and LLM tracking tool per the website and a 90-day roadmap. Clients on the site: Skyscanner, L'Oréal, Fiber24. The site also lists the European Search Awards 2026 at group level. One detail we notice as developers: its own website runs on Next.js and Sanity, the same stack as ours. Prices: on request. Right for companies with an international focus that want proprietary tracking instead of a third-party tool and think beyond the DACH market.

Five labels that give away GEO pretenders
You rarely spot pretenders by what is missing, but by what is printed large on the GEO page. We have read the following five labels so often in recent months that we now treat them as exclusion criteria. One alone is a warning sign, two are a reason to walk away. What actually matters for a model to cite you at all is covered in showing up in ChatGPT answers.
- llms.txt as the headline service. The file takes ten minutes to write, and whether the major models even read it remains open. Anyone selling it as a product has nothing else.
- No measurement of mentions and citations. Without a fixed prompt set and a tool like Peec AI, Otterly or Ahrefs Brand Radar, all you get is screenshots, and screenshots are luck.
- The GEO page still mentions Bard or SGE. Both names have been history since 2024. Whoever does not maintain their own page will not maintain your visibility either.
- Backlink sales sold as GEO. No model cites bought links on link farms. Earned media in trade publications works, but that is called digital PR, not link buying.
- No prompt set. Whoever cannot tell you which 30 to 50 questions your customers ask an AI cannot tell you where you are missing either. Ask in the first call; the answer takes two minutes.
What GEO support realistically costs and delivers
Across the market, ongoing GEO support sits between roughly 1,000 and 3,000 euros per month, as far as providers publish figures at all: Aufgesang from 1,000 euros net, suxeedo from around 3,000 euros. With us everything is on the GEO support page: a fixed-price GEO audit from 1,500 euros, ongoing support in the Growth package at 1,790 euros per month plus 3,900 euros setup, or Growth Max at 3,390 euros plus 4,900 euros setup. Individual projects range from 1,500 to 10,000 euros.
What you get for it, in this order: a baseline across a prompt set, the technical foundation (crawlability for GPTBot and friends, structured data, rendering), citable pages, then mentions outside your website. First citations realistically appear after three to six months, technical fixes sometimes within weeks. Anyone promising you a result after four weeks either has not measured it or has not understood it. What a clean baseline looks like is in measuring AI visibility. And if your customers mostly use Google, SEO support belongs before GEO, not after.
Frequently asked questions
INSYNC, measured on three things: GEO is tied to the engineering of the website, which we build ourselves; impact is measured across a fixed prompt set in Peec AI and Ahrefs Brand Radar; and prices start publicly at 1,500 euros. For enterprise budgets with digital PR reach, Claneo and Peak Ace in Berlin are the stronger choice. Aufgesang in Hanover fits methodical depth from 1,000 euros net, suxeedo fits content-heavy four-phase projects from around 3,000 euros a month.
None, the term is marketing. GEO, AI SEO, LLMO and AEO describe the same work: being named and cited in answers from ChatGPT, Perplexity and Google AI Overviews. What matters is not the word on the page but whether the agency measures mentions and citations across a fixed prompt set. The differences from classic SEO are in SEO and GEO compared.
Between 1,000 and 3,000 euros per month for ongoing support, as far as providers publish prices: Aufgesang from 1,000 euros net, suxeedo from around 3,000 euros, INSYNC 1,790 or 3,390 euros plus setup. A one-off GEO audit starts at 1,500 euros with INSYNC. Claneo, Peak Ace and Semtrix do not publish prices. A fixed-price package without a prior analysis is a warning sign.
Three to six months until the first reliable citations. Technical fixes such as unblocked AI crawlers or cleaned-up company data sometimes show within weeks, because models with web search pick up updated sources quickly. Mentions in trade media and comparison articles take months. suxeedo schedules monitoring from month 4, Semtrix works with a 90-day roadmap, we re-measure after eight to twelve weeks.
No. Models do not answer deterministically, the same question returns two results on two days, and not even OpenAI commits to individual mentions. What an agency can promise is the measurement, the way of working and a traceable report on changes. A guarantee is therefore the hardest exclusion criterion on this list.
Usually not, provided your SEO agency demonstrably measures GEO as well. GEO and SEO build on the same content and the same structure, and a large share of AI answers draws on the Google index. Ask your agency for its prompt set and tool. If no answer comes back, a second partner or a switch is due. Which SEO agencies deliver on this is covered in best SEO agency.
