GEO agency
GEO agency in the Netherlands.
Search is turning into answers, and answers name their sources. Ovolum is a Dutch GEO agency working in English: we make your company one of the sources AI systems cite.
The short answer
Ovolum is a generative engine optimization (GEO) agency based in the Netherlands, serving Dutch and international clients in English. We build the layer that makes websites citable for ChatGPT, Perplexity, Gemini and Google’s AI Overviews: answer blocks at the top of every key page, machine-readable structure, consistent entity data, visible freshness and authority beyond your own domain. Results are measured per AI system and reported monthly — alongside your classic Google positions, which the same build strengthens.
Why GEO deserves an agency
The citation game follows its own rules. Large-scale studies show that over a quarter of ChatGPT’s most-cited pages are invisible in the classic Google top, and fewer than one in ten AI-cited sources also ranks on Google’s first page. Winning here takes a dedicated method: content built to be quoted, data built to be read by machines, and authority built where language models actually look. That method is our daily work.
How the studio works
Every engagement opens with a baseline: where do the AI systems mention you today, and which questions decide your market. We then build page by page — the core answer first, questions as headings, FAQ schema underneath, dates in view, an llms.txt introducing your site to language models, and entity data kept identical everywhere. You speak directly with the makers, and the monthly report shows citations per system next to your Google movement.
For Dutch and international clients alike
We serve two groups in one language: Dutch companies that want their AI visibility handled in English-level craft, and international companies entering or serving the Dutch market. For the second group we pair GEO with market knowledge — how Dutch buyers search, compare and decide — so the citations land in front of the right audience from day one.
Frequently asked questions
What does a GEO agency actually deliver?
Citations — measured. Concretely: citable answer structures on your key pages, technical signals (schema, llms.txt, freshness), consistent entity data, authority building beyond your site, and a monthly report of mentions per AI system on the questions that decide your market.
How is GEO different from SEO?
SEO competes for positions on a results page; GEO competes for a mention inside the answer itself. The foundations overlap — which is why one citable build serves both. Our comparison of GEO and SEO lays out the full picture.
What does GEO cost in the Netherlands?
Serious programmes in the Dutch market run between €500 and €3,000 per month depending on scope and competition. Your own proposal states one fixed monthly rhythm for a defined scope — agreed up front, cancellable monthly.
Do you also serve companies outside the Netherlands?
Yes — the craft travels. We work in English for clients across Europe, with the Dutch market as our home ground and multilingual builds as a specialty.
