People do not Google "best practices" when things break. They Google symptoms. These diagnostic guides map symptoms to failure modes and solutions.

Each diagnostic symptom maps to underlying decision traces in generative search.

How Diagnostic Guides Work

Each diagnostic guide follows a symptom-first approach:

  1. What the system is doing: Observable behavior that indicates the issue
  2. Why the symptom appears: Root cause explanation tied to retrieval mechanics
  3. Which failure mode it maps to: Links to specific failure patterns in the GEO system
  4. Diagnostic steps: How to verify the cause
  5. Mitigation path: How to resolve the issue

These guides funnel directly into GEO Failure Modes for detailed mechanics.
