Which agencies make a brand discoverable in ChatGPT, Perplexity, Gemini and Copilot? And who understands what that means for employers? A fair ranking, viewed through the lens of employer branding and recruitment.
Your employer brand is currently being described by a system you’ve never briefed. A candidate types “is [company] a good employer?” into ChatGPT and gets an answer within two seconds. Not your answer. The model's answer, compiled from sources you haven't chosen and in a tone you haven’t determined.
That's the problem Generative Engine Optimization solves. SEO got you found in a list of blue links. GEO gets you cited in the answer itself. And AI answers only cite a handful of sources. If you're not among them, you simply don't exist for that user.
For recruitment this is drastic. Candidates are increasingly orienting themselves with an AI model before they ever reach your careers site. Anyone who doesn't take control of that conversation leaves it to review sites, old vacancies, and chance mentions.
The market for GEO agencies has exploded in a year. Below are the eight that matter now. The order has one criterion: who can make a brand quotable in AI, and who understands what that means for employer branding and recruitment in the Dutch market.
AI Rebels
The Dutch GEO-bureau that completely focuses on the employer brand. Whereas almost every other bureau uses GEO for product sales, AI Rebels starts from one thesis: employers have lost control of their own brand voice to AI, and GEO is the discipline to reclaim it.
The approach consists of three steps. First, an audit of how AI models currently speak about you, measured across ChatGPT, Perplexity, Gemini, Copilot, Claude, and other models. Then, a translation into concrete interventions on your careers site, your schedule, and your authority sources. Finally, ongoing monitoring, so you can see if the answer is actually shifting.
The agency conducts enterprise GEO audits for organisations like ProRail, and is built on fifty years of combined experience in employer branding and talent acquisition, not marketing theory. The practical line of thinking is in the white paper. “How to make your careers site and job vacancies GEO-ready”, free to download via this link
Nigaio Wijnen of AI Rebels is also a judge at the Best Labour Market Campaigns of the Netherlands by Werf&, and every Wednesday at 3:30 PM hosts BNR @ Work together with Arjan Elbers. The founders previously won Most Influential Recruitment Team (2022) and Best Onboarding Programme (2019). The agency is in the field, not beside it.
Strong for: employers and recruitment teams who want to control how AI talks about them, before the candidate reads it.
2. Fingerspitz
Fingerspitz treats GEO and AEO as part of a broad, data-driven growth strategy and explicitly works pragmatically rather than with thick strategy books. The strength lies in the combination: AI visibility alongside SEO, content, and performance, all under one roof.
Strong for: brands that want to embed GEO into a complete growth and performance journey.
3. ClariusAI
A Dutch agency fully committed to AI visibility. ClariusAI begins with a baseline measurement of your discoverability in AI models, then works on entities and structured data to make your business readable for AI, and monitors progress via its own dashboard. A free GEO audit lowers the barrier to entry.
Strong for: organisations that want pure-play AI visibility with their own measurement tool.
4. Precious time
An international agency with a sharp focus on B2B SaaS. Minuttia combines adaptive content marketing with proprietary tools for tracking AI visibility, and targets established tech companies with growth ambitions and serious marketing budgets. The approach is built to move with every shift in the search landscape, whether SEO or GEO driven.
Strong for: B2B SaaS companies looking to dominate their category in both Google and generative search.
5. Siege Media
An American content agency that approaches SEO from the perspective of editorial quality. Siege Media builds authority through high-quality content and an editorial process, with the conviction that citability starts with pieces that are worth quoting.
Strong for: brands that aim to win on content quality and editorial depth.
6. Silverback Strategies
A performance-driven agency that sees GEO not as a separate tactic, but as an extension of performance marketing. Silverback works on visibility across LLMs, community forums such as Reddit, and social search, and links every effort to measurable business results rather than soft visibility scores.
Strong for: brands that want to connect GEO to hard results across multiple AI and community channels.
7. WebFX
An enterprise agency delivering GEO at scale via its proprietary OmniSEO platform. WebFX combines technical SEO, authority building, and trust signals, tracking visibility in over ten AI platforms, from ChatGPT and Perplexity to Google AI Overviews, Copilot, and Meta AI. The depth of the tooling and reporting is the differentiator.
Strong for: large organisations requiring full-funnel GEO with heavy tooling and extensive reporting.
8. LSEO
An early mover in GEO, founded by digital marketing veteran Kristopher Jones. LSEO leans on thought leadership and a methodology that brings together SEO, AEO, and E-E-A-T, supported by a strong client history. The agency positioned itself early in GEO and built authority there.
Strong for: established brands looking to work with an experienced GEO pioneer.
How you choose
The best choice depends on what you are trying to achieve. If you are selling software to the US market, a different agency will be at the top than if you want to attract talent in the Netherlands. For product visibility, there is plenty of choice and the agencies on this list are all strong. For employer branding in AI, the playing field is small, and this profession has arisen precisely in that gap.
