Google AI Overviews: What Gets Featured and Why

You rank #1 for your target keyword. You've dominated that position for months. Then Google rolls out AI Overviews, and suddenly a completely different site appears at the top of your results page—synthesizing information from sources you've never heard of.

This scenario is playing out across millions of queries. According to Semrush research, Google AI Overviews now reach 1.5 billion users monthly across 200+ countries, fundamentally changing what it means to "rank" on Google. Understanding what gets featured—and why—is no longer optional.

The data reveals surprising patterns. Ranking doesn't guarantee visibility. Traditional SEO metrics barely correlate with AI Overview selection. The game has changed, and this guide shows you the new rules.

How Often AI Overviews Appear (2025 Data)

AI Overview prevalence has been volatile throughout 2025. The feature started the year appearing in about 6% of queries, peaked near 25% in mid-summer, then stabilized.

The pullback from peak suggests Google is still calibrating where AI Overviews add value versus where they harm user experience. But the long-term trajectory is clear: this feature is here to stay and expanding.

What Triggers an AI Overview: Query Characteristics

Not all queries trigger AI Overviews equally. The data shows clear patterns in which searches Google chooses to answer directly.

Query length is a powerful predictor. Semrush data shows a query with 8+ words is 7x more likely to trigger an AI Overview than shorter queries. This makes sense—longer queries express more specific intent that benefits from synthesized answers.

Source Selection: What Gets Cited and Why

This is where AI Overviews diverge most dramatically from traditional SEO. TryProfound research shows 80% of sources featured in AI Overviews don't rank organically for the query. Even a #1 position offers only an 8% chance of being cited.

The Reddit and YouTube dominance is significant. Google AI Overviews heavily weight user-generated content and community validation—the same content types that traditional SEO often dismisses as lower authority.

The Real Impact on Click-Through Rates

The AI Overview CTR impact has been the subject of significant concern—and significant misinformation. Let's look at what the data actually shows.

However, the picture is more nuanced than these numbers suggest. Semrush's tracking of identical keywords before and after AI Overview implementation found something surprising: zero-click rates actually decreased from 33.75% to 31.53%.

The strategy shift: focus on visibility and citation within AI Overviews rather than solely pursuing top organic positions. Being mentioned in an AI Overview may generate fewer clicks than a #1 ranking, but those clicks are significantly more valuable.
