Backlinks are still important in 2026, but their role has shifted. They remain a core ranking signal in Google’s algorithm, and pages without them rarely attract meaningful organic traffic. The difference today is that quality, relevance, and context matter far more than volume, and backlinks now interact with a broader ecosystem that includes AI Overviews and generative engines. This article works through the most important questions SEO professionals are asking about links right now.
How has Google’s use of backlinks changed over the years?
Google’s relationship with backlinks has evolved from treating them as the dominant ranking signal to weighting them as one important factor within a much larger system. The original PageRank algorithm, developed by Larry Page and Sergey Brin in 1997, treated every inbound link as a vote of confidence. That framing defined SEO for well over a decade.
Several algorithm updates gradually reshaped that picture. Panda in 2011 prioritised content quality. Penguin in 2012 targeted manipulative link-building and, in its 4.0 form in 2016, shifted from penalising sites with spammy links to simply ignoring those links. Hummingbird in 2013 introduced semantic and intent-based search. RankBrain in 2015 brought AI-based learning into the ranking process. Each update made backlinks one signal among many rather than the primary lever.
Google’s own internal testing confirmed that links still matter. According to Ahrefs, when Google experimented with removing links from its algorithm entirely, search quality became significantly worse. That experiment was not published as a formal study, but it has been referenced in Google Search Central content and is widely cited in the industry.
The official language around links has also softened. In March 2024, Google updated its spam policy documentation to remove the word “important” from its description of links as a ranking factor. That is a subtle but meaningful signal that Google’s public position has moved away from emphasising links, even if the underlying algorithm still relies on them.
Do backlinks still directly influence search rankings in 2026?
Backlinks still directly influence search rankings in 2026. Multiple correlation studies and industry analyses consistently show a strong positive relationship between backlink profiles and ranking positions. Pages without backlinks rarely appear in competitive search results, and the gap between linked and unlinked pages in terms of organic traffic is substantial.
The public statements from Google representatives are more nuanced. At SERPCon 2024, Google’s Gary Illyes said that Google needs “very few links to rank pages” and that links have become less important over the years. He then walked back that statement on social media almost immediately, saying he should not have said it. At PubCon Austin in 2023, Illyes had acknowledged that links are important but overestimated. Neither statement suggests links are irrelevant; both suggest their weight has decreased relative to other signals.
A 2024 internal Google document leak provided more concrete evidence. The leaked documentation confirmed that PageRank for a website’s homepage is still evaluated for every document on that site, and that links matter in the current system. This aligns with third-party data showing that the vast majority of pages ranking in the top 10 of Google have substantial referring domain profiles.
The most defensible position, based on available evidence, is that backlinks remain a significant ranking factor, but their weight has declined relative to content quality, topical authority, and user experience signals. They are necessary but no longer sufficient on their own.
What types of backlinks actually move rankings today?
The backlinks that move rankings today are editorially placed, contextually relevant, and sourced from domains with genuine topical authority. A single link from a well-regarded publication in your niche carries more weight than dozens of links from unrelated or low-quality sites. Google’s SpamBrain algorithm actively identifies and discounts unnatural link patterns, so volume without quality is not just ineffective – it can cause harm.
Dofollow vs nofollow links: what actually passes value?
Dofollow links pass PageRank directly and are the primary driver of link equity. Nofollow, sponsored, and UGC-tagged links pass less or no PageRank, but a natural link profile includes a mix of link types. Sites that have only dofollow links from outreach campaigns often look unnatural compared to sites with organically acquired nofollow links from social platforms, forums, and news coverage. The combination signals authenticity.
Understanding the difference between dofollow vs nofollow links matters because it shapes how you evaluate your link acquisition efforts. Prioritising dofollow editorial placements is correct, but dismissing nofollow links entirely misses their role in building a credible, diverse backlink profile.
What link characteristics signal quality to Google?
Google evaluates backlinks by four primary characteristics: relevance to your topic or industry, authority of the linking domain, diversity of link sources, and editorial placement within body content rather than footers or sidebars. A link embedded in a paragraph discussing a related topic on a high-authority site in your vertical is the benchmark. Directory submissions and private blog network links fail to meet these criteria and correlate poorly with both Google rankings and AI search visibility.
Digital PR has emerged as the leading tactic for earning these high-quality links. It generates editorial placements from journalists and publishers who link because the content is genuinely newsworthy or useful, which is exactly the kind of link Google rewards.
How do backlinks interact with AI Overviews and generative engines?
Backlinks influence AI Overviews and generative engines indirectly rather than directly. High-quality backlinks build domain authority and search rankings, which increases the probability that AI systems surface your content. But AI citation selection is driven more by content depth, factual density, and brand mention signals than by backlink counts alone.
Research from Ahrefs analysing tens of thousands of brands found that brand mentions correlate more strongly with AI visibility than backlinks alone. This does not mean backlinks are irrelevant to AI search; it means the mechanism is different. Backlinks help you rank, and ranking helps AI systems find and trust your content. The relationship is sequential rather than direct.
The data on AI Overviews also shows that domain authority, which is built substantially through backlinks, is a strong predictor of AI citation frequency. Sites with very high domain ratings receive far more AI citations on average than sites in lower authority tiers. A site with no backlinks and low authority is unlikely to appear in AI-generated answers regardless of content quality.
Content characteristics matter independently for AI citation. According to analysis updated in April 2026, articles that cover more facts and run longer tend to earn more AI citations. Backlinks support the authority that gets you into consideration; content depth determines whether AI systems actually extract and cite you. Both matter, and neither replaces the other.
What’s the difference between link building and link earning?
Link building is the proactive process of acquiring backlinks through outreach, guest posting, and other active tactics. Link earning is the passive process of gaining links naturally because other sites find your content genuinely valuable. Both approaches can be effective, and the most successful SEO strategies combine them rather than treating them as mutually exclusive.
Link building gives you more control over pace and targeting. You can identify specific sites, reach out, and secure placements on a timeline that fits a campaign. The risk is that outreach-based links can look artificial if the content or relationship is not credible, and paid or low-quality link schemes carry penalty risk under Google’s spam policies.
Link earning is slower and less predictable, but the links it generates tend to come from higher-authority sources and carry no penalty risk. You cannot be penalised for a link someone else chose to place. The content that earns links typically features something genuinely useful or unique: original research, proprietary data, a comprehensive resource, or analysis that other sites want to reference because they cannot replicate it themselves.
The landscape has shifted toward link earning over time. Spam email outreach has given way to personalised relationship-building. Article directory submissions have been replaced by genuine guest contributions on credible publications. One-time link placements have given way to long-term editorial partnerships. These shifts reflect Google’s increasing ability to distinguish authentic editorial endorsement from manufactured link acquisition.
How many backlinks does a page need to rank competitively?
There is no universal number of backlinks needed to rank. The right target depends on keyword competition, your domain’s existing authority, your industry, and the backlink profiles of the pages currently outranking you. Chasing a fixed number without reference to your competitive landscape is the wrong approach.
A practical benchmark for moderately competitive keywords is roughly 40 to 50 backlinks to your homepage and up to 100 to inner pages. For highly competitive terms, 100 or more authoritative referring domains is typically a minimum. In specialised B2B niches, top-ranking pages sometimes have only 50 to 100 referring domains, but those links come from highly relevant, authoritative sources.
The most effective method is to calculate the link gap: analyse the backlink profiles of the weakest pages currently outranking you using tools like Ahrefs or Semrush, then target enough referring domains to match or exceed that benchmark. This approach grounds your link acquisition in competitive reality rather than arbitrary targets.
Referring domains (unique linking sites) are a more useful metric than raw backlink counts. A single domain linking to you 50 times adds less incremental value than 50 different domains each linking once. Analysis of 11.8 million Google search results found that the number-one result had roughly 3.8 times more backlinks than positions two through ten, reinforcing that link authority still separates the top result from the rest of the first page.
In YMYL industries like finance and health, Google’s E-E-A-T considerations raise the bar further. It is not just about quantity but about the credibility and expertise signals that those links carry.
Should you disavow low-quality backlinks in 2026?
Most sites should not use the disavow tool in 2026. Google’s algorithms, including SpamBrain, automatically ignore low-quality and irrelevant links for the vast majority of sites. Google’s official guidance states the tool should only be used when a site has a considerable number of spammy or artificial links that have caused or are likely to cause a manual action. For routine spam pointing at your site, Google handles it without your input.
Google’s John Mueller has been explicit on this point: the disavow tool is not part of normal site maintenance and should only be used if you have a manual spam action. Misusing it carries real risk. An experiment by Patrick Stox at Ahrefs demonstrated ranking drops after disavowing all links flagged as “toxic” or “potentially toxic” by SEO tools, because those tools also flagged legitimate links that were passing genuine value.
The term “toxic backlinks” is largely marketing language used by SEO tools and services. Google does not use this term internally, and most random or irrelevant links pointing to your site are simply ignored rather than counted against you.
Three scenarios where disavowing is genuinely warranted are: you have received a manual action in Google Search Console specifically citing unnatural links; you previously purchased links or participated in link schemes; or you are experiencing a negative SEO attack with a sudden, large wave of spammy links. Outside these situations, the disavow tool adds more risk than it removes.
If you are managing link acquisition and technical SEO together and want to keep a clear picture of which links are helping versus being ignored, a structured approach to backlink monitoring is more valuable than reactive disavowing. WP SEO AI’s Search Engine Optimization service includes ongoing backlink tracking as part of its technical audit workflow, so you can act on real signals rather than tool-generated fear.
