I get asked this every second week now. Usually by a client who just watched a competitor with a weaker backlink profile show up in a ChatGPT answer where they didn’t. Same industry, same keyword, opposite result. Feels unfair. Feels random.
It’s not random. There’s actual data on this now, not just opinions on LinkedIn, and it points to a pretty specific answer.
Short version: backlinks still matter, but they’re not the thing deciding whether AI engines cite you. They’re the entry ticket. Once you’re in the room, something else decides if you get picked.
Backlinks and AI citations are not the same signal
This is the part most people mix up. A backlink tells Google’s crawler “this page is trusted enough to link to.” An AI citation is different. It’s whichever source ChatGPT, Perplexity, or Google’s AI Overview decided to pull from and name when generating an answer. Same idea on the surface, completely different mechanics underneath.
Ahrefs ran the numbers on this across 75,000 brands. Backlinks correlated with AI citation rates at 0.218. Weak. Brand mentions, meaning your name or domain showing up on a page whether it links to you or not, correlated at 0.664. That’s roughly 3x stronger. And it’s not a small gap in outcomes either. Brands sitting in the top quartile for web mentions averaged 169 AI Overview appearances. The next tier down averaged 14. That’s a 12x difference between the sites that show up constantly and the ones that barely show up at all.
So if you’ve been pouring your whole SEO budget into link building and wondering why a competitor with fewer links is eating your AI visibility, this is probably why. They’re getting named. You’re getting linked. Right now, named wins.
Why the “top 10” rule is breaking down
For years, the safe assumption was: rank in Google’s top 10, and you’re in the pool for AI Overviews too. That’s getting shakier. The share of AI Overview citations pulled from the organic top 10 dropped from around 76% in mid-2025 to about 38% in 2026. AI systems are reaching deeper into the index than they used to, and pulling from pages that never cracked page one.
That doesn’t mean rankings stopped mattering. It means ranking well is no longer a guarantee, and ranking outside the top 10 is no longer a disqualifier. The gatekeeping shifted.
What actually predicts citations, according to the biggest analysis so far
In May 2026, Cyrus Shepard at Zyppy pulled together 54 studies, patents, and experiments on AI citations and scored 23 factors by how consistently they showed up as predictors. It’s the closest thing this space has to real evidence instead of guesswork.
The top-scoring factors:
- URL accessibility, whether AI crawlers can actually reach and read the page, scored 9.5 out of 10.
- Traditional search rank scored 9.4.
- Fan-out rank, basically how well a page covers the related sub-questions around a topic, scored 9.3.
- Preview controls and how directly a page answers the exact question asked both scored 9.2.
Backlinks and domain authority don’t lead that list. They’re not irrelevant; they still help you clear the floor, but they’re nowhere near the top predictors once you’re being evaluated for a citation. Worth noting too, llms.txt scored lowest of all 23 factors at 2.0. If someone’s telling you llms.txt is your AI SEO fix, that’s not what the evidence says.
So where’s the floor?
Here’s the part that actually changes what you should do next. If your domain has almost no backlink profile, don’t skip straight to chasing brand mentions and PR. You’re probably not even in the retrieval pool most AI systems draw from yet, and no amount of unlinked mentions fixes that on its own. You need enough of a base to be considered credible source material in the first place.
But if you’re already sitting on a reasonable link profile and you keep adding more links expecting AI visibility to follow, you’re optimizing for diminishing returns. That effort is better spent getting your brand named in comparisons, roundups, and other people’s content, linked or not, and making sure your own pages are structured so an AI system can actually extract a clean answer from them without digging.
My take
I’m not going to tell you backlinks are dead. That claim doesn’t survive contact with the data. But I’ll also not pretend link building alone is going to get you cited in ChatGPT or an AI Overview in 2026. It won’t. Not on its own.
If you’re newer or thin on links, build the floor first. If you’ve already got that base, stop measuring success by referring domains and start measuring it by whether your brand gets named when someone asks an AI system about your space. Those are two different games now, and running both at the same time is the only way I’d approach it for a client today.
