Episode notes
PageRank: The Link-Vote Foundation
- PageRank began as a citation-style algorithm valuing links as votes and remains central to ranking decisions.
- Google evolved PageRank to weight distance from authoritative sites and to combat link farms.

- Google does use click-through-rate signals in ranking tests despite public denials.
- CTR testing is likely part of Google's evaluation loop tied to PageRank-era patents.
