How LongevityFinders Audits Listings

Verification Standards Version 2.0 · Evidence-Backed Registry

What “Website-Confirmed” Means

A listing is website-confirmed when a publicly accessible web page associated with that organization states that it provides the listed clinics or services. We do not infer services that are not explicitly documented.

Field-Level Provenance & Traceability

Pricing, features, services, and specifications are backed by raw source URL evidence. Each data point includes the source URL, exact text snippet, confidence score, and timestamp of verification.

60-Day Re-Verification Lifecycle

Our automated maintenance agent checks active source URLs every 60 days to detect price updates, discontinued offerings, and new certifications. Stale listings are placed into a re-audit queue.

Listing Claim & Corrections

Authorized representatives can claim a listing to update official pricing, add doctors/specs, or adjust descriptions. All changes undergo editorial review before publishing.
