Zero-Click GEO: The 7 Signals AI Uses When No One Clicks

In 2024, 60% of U.S. searches ended in zero clicks—up from just 26% in 2022. By mid-2025, that number hit 65%. When AI Overviews appear, it jumps to 83%.

The data is stark: according to Semrush's AI Overviews study, when AI Overviews are present, click-through rates plummet to just 8%, compared to 15% for traditional search results. The median publisher experienced a 10% year-over-year traffic decline in the first half of 2025.

But here's what most miss: zero-click doesn't mean zero-value. It means the value moves upstream—your content becomes the source that powers the answer. The question is: are you the one getting cited?

What the Research Says About AI Citations

Multiple studies in 2024-2025 have analyzed what makes content citable by AI engines. Here's what the data shows:

The 7 Signals That Drive AI Citations

Based on the research above and Semrush's finding that 88.1% of queries triggering AI Overviews are informational, here are the signals that matter:

The Traffic Paradox

Here's the counterintuitive finding from the research: while overall click-through rates are dropping, AI-referred traffic has higher engagement.

And here's another surprise: Semrush found that when comparing the same search terms before and after AI Overviews appeared, people actually clicked slightly more with the AI Overview present. The takeaway: AI Overviews appear more often for queries that naturally have low click intent, but when your content is cited, the clicks you get are higher quality.
