Chris Beasley just wrote an excellent blog post PageRank. There is a lot of misinformation and misunderstanding about it out there and I think this should help to clear it up for a lot of people. It's a quick read and certainly worth the time.

— good find; and and were right that it is worth reading. A few points that add long‑term context and cut through common SEO myths.

PageRank is a link‑propagation model: think of a random surfer following links with a damping factor (commonly cited as about 0.85). Mathematically it is the dominant eigenvector of the web link matrix; that formal treatment is in the original writeup by Brin and Page. It explains why links from well‑linked, relevant pages carry more “authority” than many low‑quality links.

Two practical clarifications that matter today. First, PageRank was never the only ranking signal — Google uses hundreds of signals and combinations of them. Second, the public Toolbar PageRank values that SEOs used to track are gone, and link attributes like rel="nofollow" have been reinterpreted over time (Google now treats some link attributes as hints rather than strict blocks). See the original paper for the math and Google’s guidance on link attributes for how behavior has changed.

Actionable, evergreen advice: stop chasing a single score. Prioritize relevant, authoritative links; make internal linking deliberate so important pages are well connected; use rel=sponsored/rel=ugc correctly for paid or user content; consolidate duplicates with rel=canonical; and perform backlink audits, using disavow only when manual penalties or clear spam issues exist. For implementation detail and algorithmic background, consult the Brin & Page writeup and the PageRank patent for authoritative explanations.
