- V1.0What is VGO
Visibility Growth Optimization and Governance for the machine world, across search, direct answers, generative AI and emerging surfaces — with AEO and the Diagnose→Learn loop.
Specification
- V1.0VGO 1.0
Core specification: Effective Visibility, SEO/AEO/GEO/SMO lenses and visibility in emerging channels, Diagnose → Decide → Act → Verify → Learn, and the methodology walkthrough.
- V1.0Principles
Principles spanning Human First, Intent First, Effectiveness First, Effective AEO, evidence, integrity, and accumulating assets.
SEO, AEO, GEO and SMO inside VGO, emerging-channel visibility, four extensions beyond generative answers, and FAQ on replacement, measurement, software, and sources.

The GEO method within VGO: decision scenarios, verified facts, evidence, prioritized action, ongoing verification and maintenance.
Rank standard
- Rank v1.0VGO Rank v1.0 frozen standard
VR0–VR10, scope, sampling, thresholds, gates and issuance bounds. The standard is in force and the production signing path is enabled; opening formal issuance is an operations decision that is not yet announced. Platform calibration is post-open optional work, not a completed claim.
Measurement
- V1.0Metrics
Separates raw exposure, Effective Visibility, and outcomes. The conceptual model is not a universal scoring formula.
- Living draftPublic Evaluation Protocol
A testable draft for judging one intent scenario. Not a universal score or certification.
Integrity
Threat model, defensive lifecycle, guardrails, and integrity scoring principles.
Stewardship
- V1.0Governance
Maintainer roles, decision model, neutrality, and versioning.
- V1.0Contributing
How to propose definitions, metrics, research, and corrections.
Research
- V1.0Research Agenda
Open, falsifiable questions the system should keep testing.
A reproducible format for baselines, interventions, results, and integrity review.
- V1.0Roadmap
From the 1.0 foundation toward measurement, provenance, integrity, and multi-surface VGO.
