What Is PageRank, and Does It Still Matter?

Aug 10, 2026 · SEO Glossary

Google confirmed as recently as its 2023 antitrust testimony and leaked internal documentation that link-based authority scores still exist inside its ranking systems. The public-facing toolbar that once displayed your "PageRank 4/10" was retired in 2016, and plenty of people took that to mean PageRank itself died. It didn't. The display died; the mathematics kept working.

If you're asking what is PageRank today, the answer has two layers: the original 1998 algorithm that made Google possible, and the evolved family of link signals that descended from it.

The Original Idea: Links as Votes, Weighted by the Voter

Larry Page and Sergey Brin's insight was that the web's link structure encodes a quality judgment. A link from page A to page B is a vote for B — but votes aren't equal. A vote from a page that itself has many votes counts for more. The math models a "random surfer" who clicks links at random and occasionally (with probability 0.15 in the original paper — the damping factor was 0.85) teleports to a random page. A page's PageRank is the probability that this surfer lands on it at any moment.

Three properties fall out of the math, and all three still matter for how you build sites:

• PageRank flows through links. A page passes a share of its score to every page it links to.
• It divides among outlinks. A page with 10 links passes more per link than a page with 300. This is why bloated mega-footers dilute everything.
• It accumulates recursively. Pages close to your strongest pages (usually the homepage) inherit strength; pages five clicks deep inherit crumbs.

What Is PageRank Now? The Evolved Version

The 1998 formula hasn't run in its original form for a long time. What Google uses now differs in ways that are documented or strongly evidenced:

• The reasonable surfer model. Google's later patents weight links by their likelihood of being clicked. A prominent in-content link passes more than a footer link nobody touches. Placement matters.
• Link spam neutralization. Since Penguin was folded into the core algorithm (2016), manipulative links are largely devalued rather than penalized — they simply pass nothing.
• Nofollow as a hint. Since 2019, rel="nofollow", rel="ugc", and rel="sponsored" are hints Google may ignore, not directives. In practice, nofollowed links still mostly don't pass value.
• Distance from trusted seeds. Variants like the patented "trusted seed" approach compute authority relative to a curated set of known-good sites rather than uniformly.

One thing hasn't changed: you can't see the number. Every third-party "authority" metric — DA, DR, and friends — is a vendor's reconstruction from their own crawl. Useful for rough comparison, but not PageRank, and Google has repeatedly said it doesn't use them.

The Part You Control: Internal PageRank

You can't dictate who links to you. You completely control how authority moves once it arrives, and this is where the concept earns its keep in 2026. Your homepage typically holds the most incoming equity on the domain. Every link it carries hands a slice onward; every additional click of depth costs another division. Practical consequences:

• Pages you want to rank should sit within 2–3 clicks of the homepage.
• Internal links from your strongest pages to your money pages are the cheapest authority transfer available.
• Orphan pages receive zero internal equity regardless of how strong your domain is.
• Redirect chains and broken links leak equity: a link that dead-ends at a 404 passes nothing at all.

You can approximate internal PageRank yourself: crawl your site, count inlinks per page weighted by the linking page's own inlinks, and rank the results. Most site crawlers compute a version of this score. It routinely reveals that a company's highest-authority internal pages are its privacy policy and login screen — linked from every footer — while the pages that drive revenue sit near the bottom.

A worked example makes the leverage concrete. Say your homepage carries 80 links: each one hands roughly 1/80th of its passable equity onward. A category page linked from the homepage, carrying 30 links of its own, passes each product about 1/30th of its smaller share. Now add one direct homepage link to a priority product page: that page jumps from receiving a fraction-of-a-fraction to receiving a full homepage share — often a bigger authority change than months of link building would produce. The math is simplified, but the direction is right, and it's why navigation decisions are ranking decisions.

Signals That the Concept Is Working (or Leaking)

You won't find PageRank in Search Console, but you'll see its shadow. Pages with strong internal linking get crawled more often — check crawl frequency per URL in your server logs. New pages linked from the homepage get discovered and indexed in hours; the same page buried six clicks deep can take weeks. And when a strong page 301-redirects, its target usually inherits rankings within days, because 301s pass PageRank.

The leaks show up in an audit: broken internal links, redirect hops, and deep click-depth are all PageRank plumbing problems. A full-site crawl maps your link graph, flags the dead ends, and shows click depth per page — which is as close as you'll get to watching your equity flow. The toolbar's gone; the plumbing still decides who ranks.
