You have probably seen this line repeated in a hundred SEO decks: Google top 3 ranking factors are content, links, and RankBrain. It gets quoted as settled fact, the kind of thing you build a content strategy around without checking where it came from. The quote is real. A Google representative did say it, in 2016, and the words are on record. But the idea that this was Google handing the industry a permanent, universally ordered top three does not hold up once you read the whole exchange and everything Google has said since. Evidence grade: mixed. The historical statement is confirmed. The timeless formula that got built on top of it is not. This piece walks through the Google top ranking factors history behind that one quote, where it came from, what it actually said, and how Google has qualified it in the years after.
What did Google actually say in 2016?
In March 2016, during a Q&A hosted by WebPromo, someone asked Andrey Lipattsev, then a Search Quality Senior Strategist at Google, about the top signals Google uses to rank pages. Lipattsev didn't hesitate. He said he could tell you what they were, and then he named content and links pointing to a site as two of them.
The person asking followed up right away: in that order, or another order? Lipattsev's answer is the part most people skip over. There is no order, he said.
That single sentence changes the whole shape of the quote. The famous "top three" wasn't delivered as a ranked list with content sitting above links. It was two items, named together, with the person who named them explicitly declining to say which one mattered more. If you've ever seen content links RankBrain top signals written up as though Google handed down a strict first, second, third hierarchy, that's already a stronger claim than the original conversation supports.
So where does RankBrain fit into a question about content and links? That part of the story starts earlier, and it's worth untangling because it explains why the question got asked in the first place.
Where did RankBrain's third-place claim come from?
Months before the WebPromo Q&A, in October 2015, Bloomberg published an interview with Greg Corrado, then a senior research scientist at Google. Corrado was quoted describing RankBrain as one of hundreds of signals Google used to rank pages, and the reporting characterized it as having become the third most important signal within a few months of its rollout.
That's the detail that set everything in motion. If RankBrain was third, the obvious next question was: what are the first two? Bloomberg's piece didn't answer that. It took another five months, and a different Google employee answering a different question, for content and links to show up as the other half of the picture.
This matters for how you read the quote today. The "top three" wasn't one clean announcement from one person at one moment. It's two separate statements, from two different Google employees, given five months apart, in response to two different questions, later stitched together by the industry into a single tidy list. Knowing that the pieces came from different places is the first step to reading the full claim with the right amount of weight.
Which caveats were already in the original conversation?
Here's the part that tends to get lost entirely when people cite this quote: the hedging wasn't added later by a skeptical blogger. It was in the original transcript, coming straight from Lipattsev himself, in the same breath as the answer everyone quotes.
Right after naming content and links, and right after saying there was no order between them, Lipattsev turned to RankBrain and said third place is a hotly contested issue. He went further and told the audience to take the whole thing with a grain of salt. He also pushed back on the idea that you could treat the three signals like a simple formula, where you add up a fixed amount of importance for links, a fixed amount for keywords, and a fixed amount for RankBrain. That's not how this works, he said. It's the same reflexive quoting that kept keyword density alive as advice long after Google had already said it wasn't a ranking signal on its own.
So the most quoted version of this story strips out the caveats and keeps the list. The actual conversation had the caveats built in from the start. Google wasn't vague about the third-place claim later, after people had taken it too literally. The person delivering the quote was vague about it in the room, in real time, while he was saying it.
That distinction is worth sitting with before you go any further, because the rest of this piece is really about how those early caveats kept getting repeated and sharpened over the following years.
How did Google qualify the claim afterward?
The 2016 quote didn't sit untouched for a decade before anyone pushed back on it. Google kept adding qualifications almost right away, and then kept doing it for years.
Just three months after the WebPromo Q&A, at SMX Advanced in June 2016, Gary Illyes was asked the same basic question: which comes first, content or links? His answer was that the order depends on the query, and that he couldn't give a concrete answer because it depends on too many things. That's a same-year rejection of the idea that there's one fixed ordering, coming from inside Google, not from an outside critic reading too much into a quote.
The qualifications kept coming. In September 2017, Illyes said plainly that he hadn't given a top three, and that importance depends on the query and the results, meaning different signals count more for different searches. John Mueller, another Google representative, added that the only constant is the goal of showing relevant results. Everything else, he said, varies.
Then in 2023, at a conference in Austin, Illyes was asked directly whether links were still among the top three ranking factors. He said he thought links were important, but that he didn't agree they were in the top three, and that they hadn't been for some time. He didn't say exactly when that changed. He also described a case where a site with no internal or external links still ranked first, purely on content, which he treated as something closer to an edge case than a general rule. That distinction matters most when you're deciding how much of your budget should go to link building in the first place, rather than when you're trying to settle an old quote.
A few months later, in a conversation reported from a search conference in Bulgaria, an attendee quoted Illyes saying Google needs very few links to rank pages, and that Google had made links less important over the years. Illyes later said he shouldn't have put it that way, which a reporter who covered the exchange read as a kind of confirmation rather than a walk-back. Around the same period, Google's own spam policy documentation quietly dropped the word "important" from a sentence describing how links factor into relevance, a small wording change but a telling one.
None of this adds up to a specific date when links lost their old standing, or a new three-item list to replace the 2016 one. What it adds up to is a steady pattern: every time someone at Google was asked to confirm the content links RankBrain top signals quote as a current, universal ranking, they declined.
What do Google's current documents say instead?
If you go looking for a replacement top three in Google's own documentation today, you won't find one. What you'll find is a consistent message that the weight given to any factor depends on the nature of the query. Google's guidance on how search ranking works gives the plainest version of this: the weight applied to each factor varies depending on what you're searching for, contrasting something like a current news search, where freshness counts for more, with a dictionary lookup, where it barely matters at all. That same logic is why search intent, not a fixed checklist, is what should decide how a given page gets built in the first place.
That one line does a lot of work. It explains, in Google's own words, why a fixed universal ordering was never going to be the right way to describe ranking, whether in 2016 or now.
RankBrain hasn't disappeared, either. Google's current guide to its ranking systems still documents RankBrain as part of how it understands the relationship between words and concepts, letting it return relevant pages even when they don't contain the exact words someone searched for. The same guide documents link analysis and PageRank as ongoing systems, noting that PageRank itself has evolved a great deal over time. Being described as less dominant than it once was, or no longer belonging in an old top-three framing, isn't the same thing as being switched off, the same way teams now build authority for AI search through more than one lever instead of chasing a single old signal. It's a pattern that shows up again in how Google frames E-E-A-T, as a lens for judging quality rather than a hard, countable ranking factor.
It also helps to notice that content, links, and RankBrain were never really three equivalent, measurable units sitting side by side. Content is a broad description of what gets evaluated. Links are a broad category of evidence and relationships between pages. RankBrain is one named system among many that process signals. Treating all three as interchangeable slots in a ranked list was always a bit of a stretch, even back in 2016.
What is the verdict for marketers?
Here's where that leaves you. The historical statement is confirmed: a Google employee did name content and links as leading signals, in response to a question built on an earlier claim about RankBrain's standing. That part really happened, and it's fine to say so. What doesn't hold up is treating Google top 3 ranking factors as a live, universal formula you can plan a content calendar around. It's also worth keeping separate from the way AI citations get picked today, since that runs on an entirely different signal set.
The stronger version, the one that gets repeated as Google's permanent, universal top three ranking factors, is not supported by the full record. The person who said it declined to rank content against links. He called the third-place claim contested while he was making it. Google's own people have spent years since then saying importance depends on the query, and that links in particular don't sit where the old quote implied.
The practical move is simple. Stop treating a nine-year-old quote as a current allocation formula for your content budget, and stop pointing to it the next time you're diagnosing an organic traffic drop. If you cite the 2016 statement at all, carry its date and its caveats along with it, because "Google said this in 2016, with these qualifications" is a much more honest sentence than "Google's top 3 ranking factors are." And don't read "not in the top three anymore" as "doesn't matter." Illyes said links were still important in the same breath as he said they weren't top three. Those two things sit together fine. If you want the detail on what actually drives citation signals for AI answers instead, that's a separate question worth reading on its own.
What would change this verdict? A dated, specific Google statement defining a current universal top three, with real scope attached to it, would be worth revisiting this for. Nothing in the public record so far amounts to that. Until it does, the honest version of the Google top ranking factors history is the one with the qualifications left in, not the one with them stripped out for a cleaner headline.
If you're rebuilding your content priorities around claims like this one, it helps to work from a system that tracks what you've already published and where the real gaps are, rather than from a single widely repeated quote. DeepSmith's Content Map maps your site's coverage against what you actually need, so decisions like this one rest on your own data instead of a decade-old soundbite.
