Backlinks still help, but AI search weighs something else more
Backlinks have not stopped mattering, but they are no longer the dominant signal once an AI system is deciding what to cite. Measured correlation data puts consistent brand mentions well ahead of raw link counts for AI visibility, even though backlinks keep doing real work for classic organic rankings. The two systems are related, not identical.
Short answer
Backlinks correlate with AI search visibility, but only moderately. Across 75,000 brands, Ahrefs measured a 0.664 correlation between consistent branded web mentions and AI visibility, against 0.218 for backlinks. Backlinks still feed classic rankings, which some AI systems draw on indirectly, but they are not the primary signal doing the work inside an AI answer.
Why backlinks mattered so much for classic search
Search engines built their trust model on links: a page linked to by many credible sites was treated as more credible itself. That model rewarded accumulation over time, which is a real reason older, well-linked domains tend to outrank newer ones in classic organic results.
AI systems that generate an answer by reading and synthesising content do not need that same proxy. They can read a page's claims directly and check whether those claims are corroborated elsewhere on the web, which is a different kind of trust-building than counting inbound links.
What the correlation data actually shows
Ahrefs studied AI visibility against several signals across a large sample of brands and found backlinks and branded mentions both correlate positively with AI visibility, but not equally. Branded mentions correlated far more strongly, at 0.664, than backlinks, at 0.218.
The study's own authors are clear that correlation is not causation, and that the sample skews toward more established domains, so this is direction rather than proof. But the direction is consistent with how these systems actually work: reading and corroborating content rather than following a link graph.

An AI system does not need a chain of links to trust a claim. It needs the claim said the same way in more than one place.
Where backlinks still genuinely help
Backlinks have not become worthless. Classic organic rankings still send real traffic, and several AI systems pull from the same organic index as one input among others, so a page that ranks well in classic search has a better starting position than one that does not.
A link from a credible, relevant site also usually carries a brand mention alongside it, which means the same piece of outreach can serve both goals at once. The mistake is chasing the link as the end in itself rather than the mention that comes with it.
What to prioritise instead
Consistency across independent surfaces does more for AI visibility than a larger backlink count. That means the same business name, category, and description on the website, on directories the business controls, on review platforms, and in any press or articles that mention it.
For a small or newer business, this is also the more achievable path. Earning a large backlink profile takes years. Making sure ten existing profiles and mentions say the same thing about the business can happen in an afternoon.
Common questions
Do backlinks help at all with AI search visibility?
Indirectly, yes. A page with a strong backlink profile tends to rank better in classic organic search, and classic rankings are still one input several AI systems draw on. But backlinks are not the signal doing the direct work inside an AI answer the way they do inside a search engine ranking algorithm.
What matters more than backlinks for AI search?
Being described the same way in multiple independent places. A business mentioned consistently across its own site, directories, reviews, and articles gives an AI system several corroborating sources to draw from, which is closer to how these systems build confidence in a claim than counting inbound links.
Should a small business still try to earn backlinks?
It is still worth doing for classic search, which remains a real traffic source, and a genuine mention from a credible site tends to double as both a link and a brand mention. The mistake is treating link building as the AI visibility strategy rather than one input among several.
Does a low-authority site have a real shot at being cited by AI systems?
Yes, more of a shot than it would have in classic search. A smaller domain with clear structure and consistent, corroborated claims about itself can be cited without a large link profile, because AI systems are reading and weighing content and mentions rather than following a link graph to establish trust.
Why did backlinks matter so much for search in the first place?
Classic search engines used links as a proxy for trust: a page linked to by many credible sites was assumed to be credible itself. AI systems that generate answers by reading and synthesising content do not need that proxy in the same way, because they can read the content directly and check whether it is corroborated elsewhere.
