Guides and pillar guides
Page	Silo	Evidence	What it is
Understanding AI search	Understanding AI Search	Observed	What AI search is, how a generated answer is assembled, and how to read the studies that claim to measure it.
Optimizing for AI search	Optimizing for AI Search	Documented	The documented requirements for appearing in AI answers, and the widely sold tactics that failed replication.
Measuring AI search visibility	Measuring AI Search Visibility	Observed	What the platform reports contain, why one measurement is one draw from a distribution, and what a defensible AI visibility report discloses.

Building an AI visibility report that survives scrutiny	Measuring AI Search Visibility	Observed	What belongs in an AI visibility report, how to sample so that a change can be told apart from noise, and the comparisons to keep off the page.
