PageRank is 1 of the oldest Google algorithms.
It was developed successful 1996 arsenic a portion of a assemblage probe project, but it remains important today. And it plays a cardinal relation successful SEO.
In this article, you’ll larn however PageRank works and however you tin usage that cognition to amended your SEO results.
But let’s commencement with the basics.
PageRank is simply a Google algorithm (though determination are galore others) that measures webpage value based connected the prime and quantity of incoming links.
It treats these links arsenic votes. And pages that person much high-quality links are considered much important successful hunt results.
Basically, the PageRank algorithm was designed to:
- Identify invaluable content: It decides which pages are astir utile and applicable based connected the links they person from different reputable sites
- Reward sites with natural, high-quality backlinks: Pages that gain links from trusted, authoritative sources are considered much important and fertile higher successful hunt results
- Discourage nexus manipulation: By valuing prime successful summation to quantity, PageRank makes it harder for sites to artificially boost their rankings done wide nexus gathering oregon nexus farms
- Organize web contented by relevance and authority: It creates a hierarchy of webpages that helps Google recognize which pages are astir authoritative connected circumstantial topics
Previously, Google would publically delegate a PageRank score—which ranged from 0 (PR0) to 10 (PR10)—to each webpage. And SEOs could spot those scores via the Google Toolbar.
This people worked connected a logarithmic scale, which galore SEOs deliberation had a logarithmic basal of five. Meaning each incremental summation represents a fivefold summation successful importance.
For example, a PR4 leafage would beryllium considered 25 times much important than a PR2 page. Not doubly arsenic important, arsenic a linear standard suggests.
Google retired its toolbar successful 2016 and removed the nationalist PageRank people show due to the fact that SEOs became fixated connected the metric. But the PageRank algorithm remains important today.
PageRank measures webpage value based connected incoming links. And however credible the root providing the nexus is.
This travel of ranking authorization betwixt pages is sometimes referred to by SEOs arsenic “link juice.” And tin beryllium visualized similar this:
When Google's founders archetypal developed the algorithm, they based it connected the thought that a nexus from 1 website to different indicated a level of spot and authority.
In their original paper introducing Google, the founders noted that not each votes are created equal.
The authorization of a leafage is taken into account. So, a nexus from a PR6 leafage is yet a much authoritative ballot than 1 from a PR2 page.
And the much links connected a page, the much their powerfulness is diluted.
This means it’s much beneficial for SEO erstwhile a leafage links to their site only. Rather than tons of antithetic sites.

Google’s Lawrence Page (Larry Page) and Sergey Brin developed PageRank based connected the thought that accusation connected the web could beryllium ranked based connected a page’s popularity via links. And the first PageRank patent was filed successful September 1998.
It became the archetypal algorithm that Google utilized to cipher a webpage’s importance.
Their insubstantial explains that “the citation (link) graph of the web is an important assets that has mostly gone unused successful existing web hunt engines.”
PageRank is what made Google truthful unique.
The Introduction of the Google Toolbar
Google launched the Google Toolbar successful 2000. This was important successful PageRank’s past due to the fact that it enabled users to spot immoderate page’s score.
But SEOs soon became fixated connected expanding PageRank arsenic a mode to amended rankings. Their extremity was to get arsenic galore links arsenic imaginable from webpages with the highest PageRank possible.
This led to manipulation, with wealth changing hands for links. So, links were placed successful unnatural locations and successful bulk.
The archetypal PageRank patent expired successful 2018 and wasn’t renewed. And a erstwhile Google worker confirmed astir this clip that the archetypal algorithm hadn’t been utilized since 2006.
But that didn’t mean PageRank was over. Because the archetypal patent was seemingly replaced by this caller one from 2006.
This patent references “seed sites successful the trusted effect sets” and defines these arsenic “specially selected high-quality pages which supply bully web connectivity to different non-seed pages.”
Two examples provided were the Google Directory (which was inactive unrecorded erstwhile the patent was filed) and The New York Times. Effectively due to the fact that they were seen arsenic reliable, covered galore interests, and were connected to galore different websites.
The caller patent looked to springiness a ranking people to a webpage based connected however acold distant it is from a effect set. That said, this patent doesn’t really notation PageRank (or assertion to beryllium an updated mentation of the algorithm).
But the SEO assemblage has understood that it acts arsenic a PageRank modifier based connected the proximity to the effect acceptable of sites.
Google Retires the Toolbar
Google stopped updating its PageRank people successful December 2013. And wholly retired its toolbar successful 2016, which removed the public-facing PageRank metric.
Without a publically shown score, determination was nary close measurement of a webpage’s authorization (at slightest officially). So, it became harder for SEOs to manipulate the algorithm.
In March 2024, a leak of Google's interior API documents revealed however Google ranks webpages. And uncovered that Google uses aggregate PageRank versions internally.
While we don't cognize precisely however each mentation works, this tells america that Google inactive considers the value of links erstwhile ranking pages.
Here are the PageRank versions referenced successful the leaked papers and what they could perchance mean:

In 2009, Google’s Matt Cutts said PageRank sculpting wouldn’t work. Because PageRank would inactive beryllium diluted by the beingness of nofollow links.
Google yet announced it would dainty the nofollow attributes arsenic “hints.” In different words, it would determine whether these links should walk PageRank.
