Built for citation, not just clicks

Every product page earns its place in the index.

Each record combines source evidence with normalized tiers and at least one calculation that is unique to TierDrift.

Append-only evidence

A new observation creates a new immutable snapshot. Existing history is never silently replaced.

Human-verifiable sources

Every price points back to the public pricing page and carries a precise observation timestamp.

Machine-readable offers

Visible plan data is mirrored in structured Offer markup, sitemap entries, and llms.txt guidance.
