PageRank is the link-based algorithm Larry Page and Sergey Brin built at Stanford in the late 1990s to measure how important a web page is by counting and weighing the links pointing to it. The public PageRank score you might remember from an old toolbar is gone, but the link-analysis idea behind it is still part of how Google evaluates pages today.
If you’ve stumbled across an old SEO forum post warning you to “build your PageRank,” you’re not crazy for being confused. The term gets thrown around like it still means what it meant in 2005. It doesn’t, not exactly. Let’s sort out what PageRank actually was, how it worked, and what’s left of it now.
Original Idea: Links as Votes
Page and Brin filed their patent for PageRank in 1998, the same year they founded Google. Their insight was simple but unusual for the time: treat every hyperlink on the web as a small vote of confidence. A page that received links from many other pages was probably worth paying attention to. A page that received links from already-trusted pages counted for even more.
Think of it like academic citations. A research paper cited by hundreds of other papers carries more weight than one nobody references, and a citation from a respected journal counts for more than one from an obscure blog. PageRank applied that same logic to the web’s link structure, treating it as a giant graph of pages voting for each other.
This was a real departure from how earlier search engines worked. AltaVista and Excite, the dominant search tools of the mid-1990s, mostly ranked pages by matching keywords on the page itself. That made them easy to manipulate; stuff a page with the word “camera” two hundred times and you’d outrank an actual camera retailer. PageRank gave Google a second signal, one based on what other websites thought of a page rather than what the page claimed about itself.
How It Worked, Without the Math
You don’t need the formula to understand the mechanics. Picture the entire web as a network of pages connected by links. PageRank ran a calculation across that network and assigned each page a score based on two things: how many pages linked to it, and how important those linking pages were themselves.
A link from a small, low-traffic blog passed along a little bit of authority. A link from a major news outlet or a well-established university site passed along a lot more, because that source had built up authority of its own through links pointing to it. The effect cascaded outward across the whole web, which is why Page and Brin originally called it a “global ranking” of every page, independent of any specific search query.
That’s an important distinction beginners often miss. PageRank measured a page’s general importance. It said nothing about whether that page was relevant to your specific search. Google combined PageRank with other relevance signals, like keyword matching and anchor text, to decide what to actually show you for a given query.
The Toolbar Score and Why It Disappeared
For years, Google let people see a rough version of this score through the Google Toolbar, a browser add-on that displayed a number from 0 to 10 next to any page you visited. A score of 8 or 9 meant serious authority, the kind of number you’d see on a major government or news domain. Most ordinary sites sat somewhere between 1 and 4.
The problem was predictable: once people could see the number, they started chasing it. Link farms, paid links, and comment spam all exploded as site owners tried to inflate their visible PageRank rather than build genuinely useful pages. Google stopped updating the public score in December 2013, and in April 2016 it shut the toolbar feature off entirely. A Google representative said at the time that the Toolbar PageRank score had become less useful to users as an isolated metric, and that retiring its display would help avoid confusion about the metric’s significance.
That announcement is where a lot of the confusion started. People assumed Google killed PageRank itself. It didn’t. Google killed the public number. Google’s Gary Illyes clarified at the time that PageRank was only being removed from the Toolbar and would remain part of Google’s ranking systems.
Is PageRank Still Used in 2026?
Yes, in an evolved form. You won’t find a visible score anywhere, and Google has never published exactly how today’s version works. But the underlying concept, that links between pages carry signal about authority and trust, still feeds into ranking. A leaked batch of internal Google API documentation that surfaced in 2024 referenced several active PageRank variants, including one labeled RawPageRank and another called PageRank2. Neither Google nor outside researchers have explained exactly what separates these variants, so treat that detail as informative rather than something you can optimize against directly.
What matters for a beginner is the takeaway, not the variant names: link quality still counts. Earning links from sites that are themselves trusted and well-linked still carries more weight than collecting links from low-quality or spammy sources. That’s the one piece of PageRank’s original logic that has survived two and a half decades of algorithm changes mostly intact.
It’s worth being honest about the limits of what’s publicly known here. Google has never released a complete list of current ranking factors, and nobody outside the company can say with certainty how heavily link-based signals are weighted today relative to content quality, page experience, or the dozens of other signals folded into modern ranking systems. Anyone claiming precise percentages is guessing.
Common Confusion: PageRank vs. Domain Authority
One mix-up worth clearing up directly. PageRank is Google’s own internal metric. Domain Authority, the score you might see in tools like Moz or Ahrefs, is a third-party estimate built by those companies to approximate how a site might perform in search. They’re correlated in a loose sense, since both try to measure link-based trust, but they’re calculated differently and Google has no involvement in either Domain Authority or its competitors. If a tool shows you a “PageRank” number today, it’s not actually pulling that figure from Google. Google doesn’t publish one.
What This Means for You
You can’t check your PageRank score anymore, and you shouldn’t try to optimize for one. What you can do is apply the principle that made PageRank useful in the first place: earn links from sites that are themselves credible, relevant to your topic, and trusted by their own readers. That’s still sound advice in 2026, even if the algorithm behind it looks nothing like the simple link-counting formula from 1998.

FAQ’S About What Is PageRank
1. Does PageRank still exist?
Yes. The public toolbar score was retired in 2016, but link-based authority signals descended from the original PageRank concept are still part of how Google evaluates pages.
2. Can I check my PageRank score?
No. Google no longer publishes a public PageRank number for any site. Tools that show a “PageRank” score are using their own proprietary estimates, not Google’s actual figures.
3. Is Domain Authority the same as PageRank?
No. Domain Authority is a third-party metric from Moz, separate from anything Google publishes or confirms. They both attempt to measure link-based authority, but they’re calculated independently and won’t always agree.
4. Why did Google get rid of the PageRank toolbar?
The visible score encouraged link manipulation. Once site owners could see their exact number, many turned to link farms and paid links specifically to raise it, which pushed Google to stop showing the metric publicly.
