AI Visibility
Public Evidence Layer
Public Evidence Layer is an AYSA operating label for the crawlable, current and source-backed web records that support important claims about an organisation, product or service.
What it means
The layer can include policy pages, product specifications, locations, authorship, case evidence, dates and Structured data that agrees with visible content. Provenance records origin and change history; it does not prove that a claim is true or force an AI system to use it.
Why it matters
When facts live only in sales decks, private dashboards or inconsistent pages, people and retrieval systems cannot inspect a stable source. A coherent evidence layer gives each material claim an accountable public home.
Example
A software vendor publishes one dated security page with certification scope, issuer and expiry, then aligns product pages and schema to that source instead of repeating an undated `certified` badge.
Common mistakes
Do not call this a Google ranking layer, publish private or regulated data, duplicate the same claim across uncontrolled URLs or treat schema as evidence by itself. Public does not mean accurate, authorised or current.
How AYSA handles this
Signals reviewed
claim, canonical evidence URL, owner, effective date, cross-page consistency
Problem AYSA can identify
AYSA can find important supplied claims with no public source, conflicting copies or stale supporting dates.
Recommendation prepared
The proposal assigns one maintainable evidence page and aligns approved references without exposing restricted data.
Approval preview
The user sees the claim map, source hierarchy, affected pages and exact proposed changes.
Execution
AYSA can update approved WordPress pages, metadata, schema and internal links within the supported scope.
Verification
AYSA recrawls the evidence URL and confirms consistency across linked public representations.
Limits
A public source cannot guarantee retrieval, ranking, citation or legal sufficiency.
