Google’s Ranking Formula Has Two Halves — and Most SEOs Ignore One of Them
Court documents show user engagement is literally half of Google’s ranking formula.
The DOJ antitrust trial exposed Google’s two-pillar ranking architecture — Quality and Popularity. Most SEOs focus entirely on Quality and ignore the Popularity half.
Most SEOs spend all their time on content quality, backlinks, and technical SEO.
That’s half the equation. Literally half.
Court documents from the DOJ antitrust trial revealed that Google’s ranking architecture runs on two top-level signals: Q* (Quality) and P* (Popularity). Two pillars, weighted together, producing the final ranking.
Quality is the side the industry knows well — content relevance, E-E-A-T, backlink profiles, page speed, crawlability. Thousands of blog posts and conference talks have been devoted to these factors.
Popularity is the side most people ignore. And it’s powered by something very specific.
What feeds the Popularity signal.
According to testimony and documents from the trial, P* draws directly from two sources: Chrome browser visit data and NavBoost user interaction signals.
Chrome visit data means Google is tracking which sites real users actually visit — and how often. NavBoost, as we’ve covered before, processes click-and-query data from search results. Together, these systems measure something straightforward: do real people actually engage with your site?
This isn’t a minor input. It’s a top-level ranking pillar, sitting right alongside everything the SEO industry has been optimizing for years.
Why this blind spot exists.
The SEO industry grew up optimizing for Quality signals because those were the signals Google talked about publicly. Google published guidelines about content quality. Google’s engineers gave talks about E-E-A-T. Google’s documentation focused on crawling, indexing, and content relevance.
What Google didn’t talk about publicly was the Popularity half. For obvious reasons — acknowledging that click behavior influences rankings invites manipulation. But the antitrust trial forced Google to reveal its architecture under oath, and the two-pillar structure was right there in the evidence.
The opportunity.
Think about what this means practically. If you’ve been investing heavily in content quality, link building, and technical SEO but your rankings have plateaued, you may have maxed out your Quality signals. The Popularity side of the equation — the side driven by user engagement and click behavior — might be where the untapped opportunity sits.
This is also why two sites with similar content quality and backlink profiles can rank differently. If one site generates more genuine user engagement — more clicks from search results, more return visits, longer time on site — it scores higher on the Popularity pillar. Same Quality, different Popularity, different ranking.
