Generative engine optimization is the practice of increasing a brand's visibility inside AI-generated responses. It focuses on the signals large language models rely on, particularly how widely and consistently a brand is mentioned across credible sources, rather than traditional ranking factors.

The signal that drives AI visibility is not backlinks, it is mentions. Being talked about across the web matters more than being linked from it. That inverts the old playbook, and it means digital PR, earned coverage, and being present where your buyers discuss things now feed directly into whether an AI recommends you.

Example:

A brand mentioned consistently across credible industry sources is more likely to surface in an AI answer than one with more backlinks but little discussion around it.

What signals drive visibility in AI-generated answers?

Research indicates that branded mentions across the web correlate far more strongly with AI visibility than backlink counts, meaning being discussed matters more than being linked.

How is GEO different from traditional link building?

Link building pursues links. GEO pursues mentions, whether linked or not, because language models learn which brands are credible from how often and where they are discussed.
