AI Search Signals
AI Search Signals are documented or directly observed inputs associated with a named component of a specific AI-search product or publisher workflow.
What it means
A signal may describe crawl access, language, location, query context, page content, source provenance or another supported input, but its existence does not reveal weight or causation. Provider documentation, controlled tests and publisher logs offer different evidence strengths and must not be combined into an internal ranking claim.
Why it matters
Evidence-labelled signals help diagnose controllable problems while preserving the boundary between an input observation and an external outcome.
Example
A report records a restrictive domain filter in an authorized web-search tool call as an input signal and a returned source URL as a separate outcome, without claiming the filter caused placement.
Common mistakes
Do not create a universal factor checklist, assign secret weights, call correlations causal, mix providers, convert citations into authority or guarantee an outcome.
How AYSA handles this
Signals reviewed
named component, input value, evidence type, provider, timestamp, observed outcome
Problem AYSA can identify
AYSA can flag unsupported factor lists, mixed evidence classes, missing product scope and correlations presented as causation.
Recommendation prepared
The register assigns each signal an owner, evidence class, test method and non-causal interpretation.
Approval preview
The reviewer sees the exact evidence, product boundary, proposed publisher action and prohibited ranking conclusion.
Execution
AYSA can test and change supported publisher-side inputs after approval; it cannot set or read provider weights.
Verification
Deployment evidence and later outcomes are stored separately so no result retroactively becomes causal proof.
Limits
The evidence remains product- and sample-bound; it does not automatically certify AI Act or legal compliance, and applicable Article 50 duties require a separate role-and-use assessment from 2 August 2026.

Quick answers
Frequently asked questions
Can an observed AI-search signal reveal its ranking weight?
No. An input observation does not disclose a provider's private weight or prove causation.
