PageRank
The link-analysis algorithm Larry Page and Sergey Brin developed at Stanford, which scores a page's importance by counting links pointing at it and weighting each by the importance of its source.
Analogy Mental model
Academic citations. A paper cited thousands of times is influential, but being cited by a Nobel laureate carries a different kind of weight than being cited by an unknown undergraduate.
In practice What you actually do
Use PageRank as a mental model rather than a number to chase. The public toolbar score was retired years ago, but the logic still governs how equity flows through your internal structure. When you need a comparable figure, use third-party proxies such as Ahrefs DR, Moz DA, or Majestic Trust Flow.
Where people get burned Pitfalls
Quoting a PageRank score today communicates nothing. Report ranking movement, organic sessions, and the quality of links you earned instead.
