The SUO Codex:Search User Optimization, from Algorithm Obedience to Human Resonance

Description

The SUO Codex is the canonical definition of Search User Optimization (SUO), a discipline that relocates where optimization begins. Search engine optimization begins with the query. Search User Optimization begins with the mind that produced it.

SUO is not Search Experience Optimization (SXO), which improves the encounter with a page after arrival, and it is not user-first optimization, a set of practices for serving a visitor once they are on site. Both begin after the person shows up. SUO models the person before the query is typed.

The Codex sets out the SUO Stack, the Five Layers of Resolution, and the I.N.S.I.G.H.T. checklist, grounding each in established research on information seeking and cognition: Robert Taylor's four levels of information need, Nicholas Belkin's anomalous state of knowledge, Carol Kuhlthau's information search process, Pirolli and Card's information foraging theory, Bartlett on reconstructive memory, Sweller on cognitive load. It then applies that foundation to the retrieval and selection layer now standing between a person and an answer, including parametric memory, retrieval-augmented generation, and the economics of grounding.
