The Visibility OS Observatory

A longitudinal measurement system for studying when brands are mentioned, cited, recommended or omitted across AI discovery systems, and what changes appear to influence those outcomes.

Why this existsRead methodology →

From documenting AI visibility to measuring it.

Public events tell us what changed in the ecosystem. The Observatory records what changed in actual outputs, citations and representation over time.

01

Prompt set

Define repeatable commercial and informational queries around a brand, category or entity.

02

Observation

Capture the answer, platform, model context, citations, retrieved domains and representation signals.

03

Intervention

Change one meaningful variable such as entity markup, page structure, source coverage or crawler policy.

04

Remeasure

Track whether visibility, citation persistence, recommendation status or ambiguity changes.

Experiment registryPublic methods, cautious conclusions

Every test gets a hypothesis and evidence trail.

Experiments are designed to distinguish correlation from stronger causal evidence. Results remain classified as established, strong, emerging, mixed/open or disconfirmed where appropriate.

VOS-EXP-003 — llms.txt Discoverability

Test whether publishing and revising llms.txt produces any measurable change in retrieval, citation or representation outcomes.

Hypothesisllms.txt alone will not reliably increase AI visibility without corresponding retrievable and authoritative web content.
Baseline + weeklyNot measured yet
draft0 observations

VOS-EXP-002 — Entity Relationship Clarity

Test whether clearer machine-readable relationships between an organization, founder, products and canonical pages correlate with more consistent AI representation.

HypothesisClearer entity relationships will reduce identity ambiguity and increase consistency of brand and entity representation across AI systems.
Baseline + 30-day remeasurementNot measured yet
draft0 observations

VOS-EXP-001 — Citation Persistence Baseline

Measure how often the same domains and pages remain cited across repeated runs of the same prompt set.

HypothesisAI citation visibility is probabilistic, but citation persistence can be measured as a stable longitudinal signal when prompts and measurement conditions are controlled.
WeeklyNot measured yet

Raw measurements are not automatically public.

Customer audits, contributed prompts, URLs and response text remain private by default. Public research uses only explicitly publishable records or anonymized and aggregated findings.

Public research

Opted-in records

Studies may expose methods, aggregate findings and approved examples where publication rights are clear.

Private audits

Private by default

Commercial measurement records are not exposed by the public Observatory unless the contributor explicitly approves publication.

Future public stream

Visibility controls first

A public observation stream will only launch after record-level publication controls and consent rules exist in the data model.

Measurement principles

Measure first. Interpret second.

Repeated observations matter more than isolated screenshots. Probabilistic systems require longitudinal samples.

Prompt wording, platform, model context, geography, language and timing are treated as experimental variables rather than noise.

Public research can remain open while company-specific diagnosis, monitoring and intervention strategy becomes the premium layer.
