At a recent search marketing conference, Google’s Gary Illyes noted that Google requires far fewer links than before, reinforcing the notion that links are less crucial than ever in SEO. This statement from Gary underscores the increasing emphasis on other ranking factors, indicating a shift in Google’s algorithmic focus. Gary later confirmed on Twitter that he did make this remark, adding to the growing body of evidence supporting this trend.
Background of Links for Ranking
In the late 1990s, search engines discovered that links could serve as a valuable signal for assessing the authority of a website. Around the same time, Google recognized that anchor text could provide semantic cues about a webpage’s content. This innovation had its roots in a pivotal research paper by Jon M. Kleinberg titled “Authoritative Sources in a Hyperlinked Environment,” published around 1998. The paper laid the groundwork for understanding how links could help filter the vast amount of web content to improve the quality of search results.
Kleinberg’s research revealed that the sheer volume of web pages made it challenging to rank them based on quality. The paper’s significant contribution was demonstrating how links could act as an objective measure of authoritativeness, offering a way to discern credible sources from a sea of information. This breakthrough inspired further exploration into using links not only as a measure of authority but also as a gauge for relevance.
In this context, “objective” refers to something based on facts, while “subjective” reflects personal opinions. Google’s founders, Larry Page and Sergey Brin, took this concept further in their seminal paper. They proposed that the subjective opinions embedded in anchor text could serve as a metric for relevance, effectively crowdsourcing the collective judgment of millions of internet users through the web’s link structure.
Their insight was revolutionary: by analyzing the anchor text within hyperlinks, Google could glean what other webmasters thought about a given webpage, allowing for more accurate ranking based on relevance. This approach marked a significant turning point in search engine optimization, transforming how search engines prioritized content and laid the foundation for modern SEO practices.
Why Links Matter Less
When Google first began using links for ranking, anchor text was generally non-spammy and offered a reliable way to assess a webpage’s relevance and authority. Hyperlinks were mainly intended to direct traffic from one site to another, making them a natural, organic signal. However, by the mid-2000s, the integrity of link signals began to deteriorate as manipulative practices emerged. Google responded by evolving its algorithms to counteract these efforts.
By 2004 or 2005, Google started deploying statistical analysis to identify manipulated links, targeting practices that artificially inflated link value. During this time, links from website footers with “powered-by” text stopped passing anchor text value. Similarly, links near words like “advertising” ceased to influence ranking. In 2006, Google further tightened its rules by devaluing links from directories, signaling a broader crackdown on manipulative link schemes.
The pivotal moment came in 2012 with the rollout of the Penguin algorithm, a significant update that penalized websites with suspicious or spammy link profiles. Penguin’s impact was widespread, leading to the collapse of rankings for many websites that relied on questionable link-building tactics, including those heavily invested in guest posting.
As link manipulation continued to undermine the reliability of the link signal, Google took a significant step in 2019 by introducing a selective approach to nofollow links for ranking purposes. This decision indicated Google’s need to adapt to the growing problem of spammy and manipulative links. Gary Illyes from Google later confirmed that the increasing unreliability of the traditional link signal drove this change.
The evolution of Google’s link approach reflects the ongoing battle against spam and manipulation, contributing to the broader trend where links matter less as ranking factors. As a result, SEO practitioners and website owners need to focus on other signals, such as content quality and user experience, to maintain or improve their rankings in this new environment.
Google Explicitly Confirms That Links Matter Less
In 2023, at PubCon Austin, Google’s Gary Illyes revealed that links didn’t even rank among the top three factors in Google’s ranking algorithm. This disclosure underscored the diminishing importance of links for search engine optimization (SEO). Then, in March 2024, Google clarified its position by updating its spam policy documentation to reflect a lower emphasis on links in ranking determinations.
However, following the March 2024 Core Algorithm Update, Google revised this statement to remove the word “important,” suggesting that links were no longer as significant:
“Google uses links as a factor in determining the relevancy of web pages.”
This change coincided with John Mueller’s comments in early April, in which he advised SEO practitioners that there are more beneficial activities to focus on than link-building. Mueller pointed out that overemphasizing links might lead to wasted efforts that don’t necessarily improve a website’s overall quality. He stated:
“There are more important things for websites nowadays, and over-focusing on links will often result in you wasting your time doing things that don’t improve your website overall.”
Finally, Gary Illyes explicitly confirmed that Google requires very few links to rank web pages, emphasizing that links now play a minor role in SEO. This shift in Google’s approach reflects a broader trend toward other factors like content quality and user experience. This indicates that the SEO landscape is evolving away from heavily relying on link-building. As a result, website owners and professionals need to adapt their strategies to go with Google’s changing priorities.
Why Google Doesn’t Need Links
Google no longer relies heavily on links because of the advanced AI and natural language understanding integrated into its algorithms. Google’s sophisticated technology allows it to understand and analyze content much deeper, reducing the need for link-based signals. This capability suggests that Google has high confidence in its algorithms, enabling them to downplay the importance of links explicitly.
Years ago, when Google introduced the nofollow attribute into its algorithm, many link builders—especially those peddling comment spam links—claimed that comment spam was still effective. This misinformation persisted even as Google clarified that such tactics were ineffective.
As someone who began link-building at the dawn of modern SEO, I’ve seen the evolution from a heavy focus on links to a more nuanced approach that prioritizes quality content and semantic relevance. Google’s shift away from a reliance on links reflects a more sophisticated understanding of web content and signals a broader move towards better quality and user-focused SEO. This new direction implies that SEO professionals must focus more on content, user engagement, and other relevant factors rather than resorting to spammy or outdated link-building tactics.
