PageRank is likely one of the oldest Google algorithms.
It was developed in 1996 as part of a university analysis challenge, nevertheless it stays essential immediately. And it performs a key position in search engine marketing.
On this article, you’ll learn the way PageRank works and the way you need to use that data to enhance your search engine marketing outcomes.
However let’s begin with the fundamentals.
PageRank is a Google algorithm (although there are numerous others) that measures webpage significance based mostly on the standard and amount of incoming hyperlinks.
It treats these hyperlinks as votes. And pages that obtain extra high-quality hyperlinks are thought-about extra essential in search outcomes.
Principally, the PageRank algorithm was designed to:
- Establish useful content material: It decides which pages are most helpful and related based mostly on the hyperlinks they obtain from different respected websites
- Reward websites with pure, high-quality backlinks: Pages that earn hyperlinks from trusted, authoritative sources are thought-about extra essential and rank increased in search outcomes
- Discourage hyperlink manipulation: By valuing high quality along with amount, PageRank makes it tougher for websites to artificially increase their rankings by way of mass hyperlink constructing or hyperlink farms
- Arrange internet content material by relevance and authority: It creates a hierarchy of webpages that helps Google perceive which pages are most authoritative on particular subjects
Beforehand, Google would publicly assign a PageRank rating—which ranged from 0 (PR0) to 10 (PR10)—to each webpage. And SEOs might see these scores through the Google Toolbar.
This rating labored on a logarithmic scale, which many SEOs suppose had a logarithmic base of 5. Which means every incremental improve represents a fivefold improve in significance.
For instance, a PR4 web page could be thought-about 25 occasions extra essential than a PR2 web page. Not twice as essential, as a linear scale suggests.
Google retired its toolbar in 2016 and eliminated the general public PageRank rating show as a result of SEOs turned fixated on the metric. However the PageRank algorithm stays essential immediately.
PageRank measures webpage significance based mostly on incoming hyperlinks. And the way credible the supply offering the hyperlink is.
This stream of rating authority between pages is typically referred to by SEOs as “hyperlink juice.” And will be visualized like this:
When Google’s founders first developed the algorithm, they based mostly it on the concept a hyperlink from one web site to a different indicated a degree of belief and authority.
Of their unique paper introducing Google, the founders famous that not all votes are created equal.
The authority of a web page is taken under consideration. So, a hyperlink from a PR6 web page is in the end a extra authoritative vote than one from a PR2 web page.
And the extra hyperlinks on a web page, the extra their energy is diluted.
This implies it’s extra useful for search engine marketing when a web page hyperlinks to their web site solely. Slightly than numerous totally different websites.

Google’s Lawrence Web page (Larry Web page) and Sergey Brin developed PageRank based mostly on the concept info on the net might be ranked based mostly on a web page’s reputation through hyperlinks. And the first PageRank patent was filed in September 1998.
It turned the unique algorithm that Google used to calculate a webpage’s significance.
Their paper explains that “the quotation (hyperlink) graph of the online is a vital useful resource that has largely gone unused in current internet search engines like google and yahoo.”
PageRank is what made Google so distinctive.
The Introduction of the Google Toolbar
Google launched the Google Toolbar in 2000. This was essential in PageRank’s historical past as a result of it enabled customers to see any web page’s rating.
However SEOs quickly turned fixated on rising PageRank as a means to enhance rankings. Their purpose was to get as many hyperlinks as potential from webpages with the best PageRank potential.
This led to manipulation, with cash altering arms for hyperlinks. So, hyperlinks had been positioned in unnatural areas and in bulk.
The unique PageRank patent expired in 2018 and wasn’t renewed. And a former Google worker confirmed round this time that the unique algorithm hadn’t been used since 2006.
However that didn’t imply PageRank was over. As a result of the unique patent was seemingly changed by this new one from 2006.
This patent references “seed websites within the trusted seed units” and defines these as “specifically chosen high-quality pages which give good internet connectivity to different non-seed pages.”
Two examples offered had been the Google Listing (which was nonetheless reside when the patent was filed) and The New York Occasions. Successfully as a result of they had been seen as dependable, lined many pursuits, and had been related to many different web sites.
The brand new patent appeared to offer a rating rating to a webpage based mostly on how distant it’s from a seed set. That stated, this patent doesn’t really reference PageRank (or declare to be an up to date model of the algorithm).
However the search engine marketing neighborhood has understood that it acts as a PageRank modifier based mostly on the proximity to the seed set of web sites.
Google Retires the Toolbar
Google stopped updating its PageRank rating in December 2013. And utterly retired its toolbar in 2016, which eliminated the public-facing PageRank metric.
With no publicly proven rating, there was no correct measure of a webpage’s authority (at the least formally). So, it turned tougher for SEOs to govern the algorithm.
In March 2024, a leak of Google’s inside API paperwork revealed how Google ranks webpages. And uncovered that Google makes use of a number of PageRank variations internally.
Whereas we do not know precisely how every model works, this tells us that Google nonetheless considers the significance of hyperlinks when rating pages.
Listed below are the PageRank variations referenced within the leaked doc and what they may presumably imply:
- RawPageRank: Probably the essential calculation of a web page’s significance based mostly on hyperlinks
- PageRank2: An up to date model, although its precise variations are unclear
- PageRank_NS (nearest seed): This model may assist Google perceive content material relationships and establish low-quality pages
- FirstCoveragePageRank: This seems to be the PageRank worth when Google first discovers and indexes a web page
Additionally, your homepage’s PageRank influences each web page in your web site. Which means a robust and well-linked homepage can increase your complete web site’s authority in Google’s eyes.
Whereas PageRank scores aren’t public anymore, the rules behind PageRank proceed to form how Google evaluates web sites. This Google content material warehouse API leak proves that.
Not all hyperlinks are equal by way of the search engine marketing PageRank they cross. However there are extra elements that may affect PageRank—or did so prior to now.
It is advisable to perceive not solely what these influencing elements are, but additionally how they apply to search engine marketing immediately.

Hyperlink constructing turned a race between SEOs to see who might achieve as many exact-match anchor textual content hyperlinks (hyperlinks positioned over the exact phrases they needed to rank for) as potential from high-PageRank pages.
Quick-forward to immediately, and Google considers anchor textual content manipulation to be a type of hyperlink spam. And interesting on this follow can result in a handbook penalty that harms your rankings.

The Chance of a Hyperlink Being Clicked
Hyperlinks extra more likely to be clicked carry extra PageRank weight.

For instance, hyperlinks within the following areas are much less more likely to be clicked than hyperlinks in distinguished areas.

<a href="https://web site.com/" rel="nofollow">Click on this hyperlink</a>
Initially, nofollow hyperlinks didn’t cross PageRank. So, some SEOs began utilizing the nofollow attribute to sculpt the stream of PageRank—often called “PageRank sculpting.”
For instance, somebody partaking in PageRank sculpting would write visitor posts with hyperlinks to 5 totally different web sites. And add a nofollow attribute to all of the hyperlinks besides the one pointing to their very own web site.
In 2009, Google’s Matt Cutts stated PageRank sculpting wouldn’t work. As a result of PageRank would nonetheless be diluted by the presence of nofollow hyperlinks.
Google finally introduced it might deal with the nofollow attributes as “hints.” In different phrases, it might determine whether or not these hyperlinks ought to cross PageRank.
For extra info, take a look at our information to nofollow, sponsored, and UGC hyperlinks.
