What a GEO Agency Actually Does
A generative engine optimization (GEO) agency gets your brand cited by ChatGPT, Perplexity, and Google's AI answers. Here is what that work includes.
In this article
A generative engine optimization (GEO) agency makes AI engines like ChatGPT, Perplexity, Gemini, and Google's AI answers describe and recommend your brand accurately. Where an SEO agency optimizes to rank a page, a GEO agency optimizes to become a cited source inside the answer itself. Corbelix is a generative engine optimization agency for B2B SaaS and established brands.
If you typed your own company into ChatGPT and did not like the answer, that is the problem a GEO agency solves. This guide covers what the work actually includes, how it differs from SEO, and how to tell a real GEO agency from an SEO shop that added the acronym to its homepage.
What a GEO agency actually does
A GEO agency coordinates the signals AI models rely on so those models cite you. That means publishing clear, quotable answers, earning corroboration from third parties the models trust, keeping your entity data consistent, and measuring how you actually appear in AI answers over time. It is less about any single page and more about becoming part of the consensus a model repeats.
In practice, the deliverables span several surfaces at once, which is why GEO looks different from a traditional content retainer.
- Quotable content that answers the exact questions buyers ask AI
- Corroboration through digital PR, Reddit, and reviews
- Consistent entity data and schema so machines resolve you cleanly
- Measurement of your presence and share of voice in AI answers
How GEO differs from SEO
SEO aims to rank a page in a list of blue links. GEO aims to shape the synthesized answer a model gives, which depends less on any one ranking signal and more on clarity, corroboration, and consistent data across the web. The two overlap, and strong SEO helps, but optimizing for a ranked page and optimizing for a cited answer are different jobs.

The channels a GEO agency works across
Because AI models synthesize from many sources, a GEO agency has to influence more than your website. It works across AI answer engines, Google, communities like Reddit, review platforms, and earned media through digital PR. Each one is a source models read, and agreement across them is what earns a citation.
How to vet a GEO agency
Ask any agency to show, live, how your brand appears when you prompt the major AI tools with real buyer questions. A genuine GEO partner already thinks that way and has a plan to close the gaps at the source. If the pitch is indistinguishable from generic SEO, or the method is a black box, keep looking.

- They show your current AI answers, not just keyword rankings
- They explain how they earn third-party corroboration
- They report presence in AI answers, not only traffic
What results look like, and when
GEO is built, not bought. Early movement shows within the first weeks as content, corrections, and corroboration take hold, and the value compounds month over month as authority accrues and becomes harder for competitors to displace. Corbelix focuses on getting clients showing up in AI answers within 90 days.
