Yes.
That is the short answer. But you deserve the full one, because the reasons behind the answer matter.
Skepticism about link building is understandable. People have been burned by bad agencies, seen sites get penalised, and read think pieces about Google "devaluing" links every few months. The noise is real. So let us cut through it.
Google has been consistent for years: links are one of the top three ranking signals.
Gary Illyes, Google's analyst, stated in 2023 that links are still important but that the company's systems have gotten "really good at filtering out" links that are clearly manipulative. John Mueller has said on multiple occasions that quality links remain a strong signal — while also noting that Google has reduced the weight of low-quality links over time.
The takeaway from Google's own statements: links matter. Bad links matter less than they used to. Good links matter more.
That is not a case against link building. That is a case for doing it correctly.
The biggest correlation study in SEO is replicated every year. The finding never changes.
Ahrefs' analysis of billions of pages consistently shows that the number of referring domains is the single strongest predictor of organic rankings. More referring domains = higher average position. The relationship holds across industries, domain ages, and content quality levels.
Semrush's ranking factor studies show the same thing. Position 1 results, on average, have 3–4x more referring domains than position 10 results.
This is not a Google guideline. This is observed data from billions of real search results. You can disagree with the mechanism, but the correlation is not in dispute.
The "link building is dead" narrative resurfaces every 12–18 months. Here is where it comes from.
Bad link building really did get penalised. Google Penguin (2012) and subsequent algorithm updates destroyed sites that had built manipulative, low-quality, or paid link profiles. Those site owners concluded link building was dangerous — and they were right, about the kind of link building they had been doing.
Google devalued junk links. Buying directory links, spinning articles, building PBNs — Google got better at identifying all of this and either ignoring or penalising it. That is not the same as link building being ineffective. It means the floor for link quality rose.
Content-first thinking became fashionable. The "create great content and links will come" school of thought is partially right. Great content does earn links more easily than mediocre content. But it does not rank on its own in a competitive niche. You still need to build the initial link base that gets the content in front of enough people to earn organic links.
Several things have genuinely shifted.
The floor is higher. Links from generic directories, exact-match-anchor-stuffed articles, and irrelevant foreign-language sites carry much less weight than they did in 2015. If you are running a 2015 link building strategy in 2026, you will see poor results.
Relevance matters more. Google's understanding of topical context has improved dramatically with large-scale AI systems. A link from a relevant source in your industry carries a multiplier that a generic high-DA link does not.
The ceiling is also higher. A truly exceptional editorial link from a major industry publication, a well-executed digital PR campaign, or original research picked up by tier-one media — these carry more signal than ever. The signal-to-noise ratio has improved in favor of quality.
Volume is less important than it was. You do not need 500 links per month to compete. You need consistently better links than your competitors, pointing to better content, with better topical alignment.
Here is the part that does not care about your opinion on link building.
Your competitors are building links.
If they are building quality links to well-optimised pages and you are not, they will outrank you. That is not a prediction — that is how the algorithm works based on the data cited above.
Not building links is a decision to give ground. For some niches where competition is low and content quality is genuinely differentiated, you can sometimes get away with it. For any competitive keyword in any established niche — forget it.
Link building has more impact in competitive, high-commercial-intent niches:
In these categories, position 1 and position 8 represent dramatically different revenue outcomes. The investment in links pays off because the keyword value justifies it.
There are niches where you can rank without aggressive link building:
Even in these cases, a base of relevant links accelerates results. "Matters less" is not the same as "does not matter."
This gets repeated constantly by content marketers who want to justify large content budgets.
Content without links ranks poorly for competitive keywords. Full stop.
A beautifully crafted 3,000-word guide on a competitive topic with zero referring domains sits at position 60+. Add 15 quality referring domains from relevant sites, and it moves to 15–25. Add another 30, and you are in the top 5.
The content matters. It determines whether a top-ranked page earns you anything. But links are what get you there. Read more about the basics at what is link building.
Paid ads are renting traffic. Link building is buying it.
When you stop running Google Ads, traffic stops. When you stop building links, you keep the links you built. That DR 50 editorial link from a major industry publication you earned in 2024 still passes equity in 2027. The compound interest on quality links is real.
Over a 3-year horizon, a consistent link building investment of $2,000–$5,000 per month generates organic traffic that would cost multiples more in paid search to replicate. The break-even point is typically 12–18 months. After that, the economics are strongly in favor of organic.
Link building in 2026 is worth it — if done correctly.
Garbage link building is not worth it. Buying cheap links, building PBNs, and automating your anchor text distribution is not worth it. These tactics either do nothing or actively harm your site.
Quality link building — editorial outreach, digital PR, relevant placements, white hat techniques, consistent execution over months — is one of the highest-ROI SEO investments available. The data supports it, Google's statements support it, and the competitive dynamics make it close to mandatory in most niches.
