Layer 01
What Is GEO?
Most teams publish for the visible web only. This guide explains what changes when citation and retrieval systems become part of discovery.
Human-first. Machine-legible.
Playbooks for AI visibility.

Editorial trust
Hidden Layer is built for overlap: useful to humans, explicit to machines. We run tiered source policy, visible update history, and review gates for high-risk or commercial content. Automation assists workflow, but it does not get final authority over factual claims on trust-critical pages.
