Google uses hundreds of signals to rank webpages, but one of the most important ideas behind its algorithm is PageRank.

PageRank was one of the original systems that helped Google decide which pages should appear first in search results. It works by analyzing links between websites and using them as signals of trust and authority.

In simple terms, every link to a page acts like a vote. Pages that receive links from trusted websites tend to earn more authority, which can improve their ability to rank in search results.

Even though Google’s algorithm has evolved significantly since the early days of the web, the core concept behind PageRank still influences modern SEO.

In this guide you’ll learn:

  • What PageRank is
  • How PageRank works
  • Whether PageRank still matters today
  • Practical ways to improve the signals PageRank relies on

Understanding PageRank helps explain why backlinks still matter in SEO.

How PageRank Works

PageRank works by analyzing the link structure of the web.

Every webpage can pass a portion of its authority to other pages through links. When one site links to another, Google interprets that link as a signal that the destination page may be useful or trustworthy.

However, not all links pass the same value. Several factors influence how much PageRank flows through a link:

  • The authority of the linking page
  • The number of other links on that page
  • Whether the link is followed or marked nofollow, sponsored or ugc, which Google treats as hints rather than strict rules

For example, a link from a well known news website may carry significantly more weight than a link from a brand new blog. Google’s other link analysis systems also use links to work out what a page is about, which is why links from related sites tend to help more.

PageRank also spreads through the web in a chain effect. If Page A links to Page B, and Page B links to Page C, some authority can flow through the entire network of pages.

This concept helped Google organize the web in a way that rewarded trusted and well connected pages.

The Original PageRank Formula (Simplified)

When Google first introduced PageRank, it used a mathematical formula to estimate the importance of each page on the web.

The simplified idea looked like this:

PageRank of a page = the sum of the PageRank passed from every page linking to it.

However, the value passed from each page was divided among its outgoing links.

For example:

  • If a page links to one page, that page receives most of the value.
  • If a page links to 100 pages, each link passes a much smaller portion.

Google also added something called a damping factor, which models how a user might randomly jump to another page instead of following links forever.

While modern search algorithms use far more signals than this original formula, the concept of authority flowing through links remains a core part of search ranking systems.

Brief History of PageRank

Basics of PageRank

Larry Page and Sergey Brin developed PageRank at Stanford in the late 1990s, and Stanford filed the PageRank patent in January 1998. It formed the core of Google’s early search algorithm, giving each page a numerical score based on the links pointing to it.

This idea changed how search engines judged and ranked pages. It also laid the groundwork for modern search engine optimization, or SEO.

PageRank’s Impact on the Web

During its prime, PageRank had a strong impact on web design and SEO practices. Webmasters and SEO professionals shifted their focus to link building as the main way to improve a site’s ranking, which led to link farms, paid links and unrelated link exchanges.

Google pushed back by announcing its Penguin system to combat link spam in 2012, then folding it into its core ranking systems in 2016. Its spam policies now spell out which link schemes break the rules. The result was a shift toward earning trusted, relevant links with content people actually want to reference.

PageRank’s Evolution in SEO

From Public Score to Behind-the-Scenes Factor

In the early years of Google, the Google Toolbar displayed a PageRank score from 0 to 10 for the page you were viewing. Website owners and SEO professionals relied heavily on it to gauge the authority of their pages.

Google stopped updating that public score after December 2013 and removed it from the toolbar in 2016. The visible number went away, but PageRank itself kept running inside Google’s ranking systems.

Modern Search Algorithms: Beyond PageRank

PageRank is now one piece of the puzzle. Google’s guide lists many other ranking systems, such as freshness systems that surface recent content and a reviews system, and Google also weighs page experience factors like mobile-friendliness and page speed. That’s why SEO now covers content quality, technical health and user experience as well as links, and why it pays to keep up with what Google’s updates mean for bloggers.

Does Google Still Use PageRank?

Yes. Google’s guide to its ranking systems says PageRank was one of its core ranking systems at launch, and that while how it works has evolved a lot since then, it “continues to be part of our core ranking systems.”

Today it operates alongside many other signals, including:

The original concept of PageRank placed heavy emphasis on backlinks as a measure of a website’s authority and relevance.

SEO has evolved since then, but quality backlinks still help search engines assess the authority and trustworthiness of a website. Websites with high-quality, relevant backlinks are more likely to earn strong rankings in search engine results.

Is Chasing PageRank Worth Your Time?

Chasing PageRank specifically may not be the most effective use of your time. You can’t see the score, and Google’s algorithm weighs many factors beyond backlinks.

Backlinks remain important, but a well-rounded approach works better: high-quality content, technical optimization, a good user experience, and links earned along the way.

PageRank vs Domain Authority

Many SEO tools now use metrics such as Domain Authority (DA) or Domain Rating (DR).

These metrics attempt to estimate the authority of a website based on its backlink profile.

However, they are not used by Google. Even Moz says Domain Authority is not a direct ranking factor.

PageRank is part of Google’s internal ranking system, while metrics like Domain Authority are created by third party SEO tools to help marketers approximate link strength.

While these scores can be helpful for comparison, they should not be treated as direct ranking factors.

How to Improve the Signals PageRank Uses

Since PageRank is based on links, improving your backlink profile remains one of the best ways to strengthen your SEO performance. Some practical strategies include:

Publishing detailed guides, research studies, and helpful tutorials increases the chances that other websites will reference your work. Focus on creating content that provides unique insights and solves your audience’s problems. Multimedia elements, such as infographics, videos, and podcasts, give other sites even more reasons to link to you.

Links from websites within your industry tend to be more valuable than random links from unrelated sites. When building a strong link profile, prioritize quality over quantity: guest posts on reputable sites in your niche, expert quotes for journalists, and relationships with other content creators all help. For a step-by-step approach, see our guide to backlink outreach using expert quote platforms.

Internal links help distribute authority across your website. Linking from strong pages to new content can help Google discover and evaluate those pages more quickly, while orphan pages that nothing links to get none of that benefit.

Avoid low quality link schemes

Buying large numbers of low quality backlinks can harm your website. Google’s spam policies treat buying or selling links for ranking purposes, excessive link exchanges, and automated link building as link spam.

Instead of chasing large numbers of links, focus on building a natural link profile from trusted sources.

User Experience as a Ranking Signal

Links alone won’t carry a page that’s hard to use. Google says that when other signals are relatively equal, content people find more accessible may perform better, and its systems look at page experience aspects like mobile-friendly pages that load quickly. Make sure your site works well on phones, loads fast, and is easy to navigate.

PageRank Myths Debunked

The number of links doesn’t guarantee a higher ranking. The quality of links often outweighs the quantity, because Google weighs the authority and relevance of the linking sites. A few high-quality backlinks from authoritative websites in your niche can do more than a large number of low-quality ones, so aim for a diverse and natural link profile.

Myth: PageRank Guarantees Search Visibility

A high PageRank doesn’t automatically guarantee top search rankings. PageRank is just one of the many factors search engines consider, and modern algorithms focus heavily on user intent and relevance. Even a page with strong links still needs relevant, high-quality content that meets the searcher’s needs, plus a good user experience and solid technical optimization.

Monitoring Your SEO Success Without PageRank

Alternative Metrics to PageRank

When looking to measure the success of your SEO efforts without relying on PageRank, there are several alternative key performance indicators (KPIs) to consider. These include organic traffic, keyword rankings, backlink profile, domain authority, and click-through rates.

Conclusion

PageRank was one of the innovations that made Google dramatically better than earlier search engines.

By analyzing links between pages, Google could estimate which websites were trustworthy and useful. This idea transformed how the web was organized and laid the foundation for modern search algorithms.

While the public PageRank score no longer exists, the underlying concept still matters today, and links remain an important signal of a page’s authority.

For modern SEO, focus on creating content worth linking to, build relationships within your industry, and earn high quality backlinks naturally over time.

When your site becomes a trusted resource that others reference, the signals that PageRank relies on will strengthen, helping your content perform better in search results.
