01The problem

Search is no longer only a list of links. Brands are increasingly discovered inside a generated answer, and almost none of them could tell you whether they appear in one, for which prompts, or how they place against a competitor.

Traditional SEO tooling had no answer, because the surface it measures is not the surface that matters any more.

02What I built

A Generative Engine Optimization platform that measures brand visibility across AI-generated responses, tracking prompt-level and competitor-level performance over time.

A brand DNA extraction layer that establishes what a brand actually sounds like, then holds generated output to it.

Long-form article generation driven by the platform's own visibility findings, closing the loop from measurement back into content.

03Outcome

Delivered as a client-facing product alongside the growth platform.
