Google AI Overviews are generative AI-created summary panels that appear at the top of Google Search results for many queries. These overviews use Google’s advanced models to synthesize information from multiple sources into a concise answer box — essentially functioning as an AI-generated explanation of what the user is searching for.
These summaries are part of Google’s broader Search Generative Experience (SGE) strategy, aiming to give users quick, direct answers before they scroll to traditional links. While these AI Overviews can be helpful for users, they are profoundly reshaping user behavior and the SEO landscape itself.
How Google Tests AI Overviews Based on Engagement
According to Google’s VP of Product for Search, Robby Stein, AI Overviews are not shown arbitrarily — Google tests them and only keeps them when they add measurable value to users.
Here’s how it works:
- Google shows overviews for selected query types.
- It tracks how users interact with them — clicks, scrolls, engagement.
- If people don’t interact, the overview may be removed for that query type moving forward.
Essentially, engagement drives visibility. Overviews that don’t “help” users — based on behaviors like clicks or interactions — get downgraded or removed, while helpful ones stick around.

Engagement Metrics That Influence AI Overview Visibility
Google uses multiple engagement signals to determine whether an AI Overview is valuable, including:
- Click-throughs on the overview itself
- Clicks on traditional links after seeing the overview
- Time spent interacting with the overview
- Scroll behavior and continued search after the overview
If users ignore the AI Overview and scroll past it without engaging, Google’s system learns that it wasn’t helpful for that type of query. Over time, Google may stop showing it for similar queries.
Why Google Removes Low-Engagement AI Overviews
Google’s position is that the goal of AI Overviews is to add value to the user experience. When AI Overviews don’t generate meaningful engagement — meaning they don’t help users find what they need — Google will:
- Reduce how often they appear
- Remove them for certain queries
- Apply learning to similar future queries
This approach aligns AI Overviews with real user behavior, ensuring they’re only shown where they help rather than just being a default top-of-page feature.

The Impact on SEO and Search Traffic
AI Overviews are transforming how users interact with search results, and engagement patterns directly affect click behavior. Third-party studies show that when an AI Overview appears:
- The click-through rate (CTR) to traditional website links can drop significantly — often nearly half compared to traditional results.
- Users often do not click links within AI Overviews — sometimes as low as 1% of the time.
Because AI Overviews can fully answer a query, users may be less inclined to scroll down and click on organic listings, creating a major shift in search traffic patterns.
Comparison With Other Google Search Features
AI Overviews are often compared to:
- Featured Snippets — short factual answers
- Traditional SERP listings — the familiar ranked links
Unlike featured snippets, which derive directly from indexed content and link users to source pages, AI Overviews summarize multiple sources in AI-generated text. These summaries may reduce the need for users to click on any result at all — a behavior not typical with featured snippets.
In effect, AI Overviews are a new tier in the SERP — one that can satisfy users without sending them to external sites.
Ads, Personalization, and AI Search Trends
Google is also experimenting with ads inside AI search experiences, including AI Overviews and broader AI-powered Search modes. These ad tests continue Google’s long-standing model of integrating ads when they are “helpful.”
At the same time, Google is exploring personalization adjustments to search, though Stein noted these are still smaller tweaks compared to the overall experience.
Changes in AI Overview Visibility Over Time
AI Overviews initially rolled out widely across millions of search queries, especially information-rich ones like detailed questions. Their visibility varies based on engagement and query type, with Google constantly refining where and when they appear.
Because engagement drives visibility, some queries may stop showing overviews entirely if users don’t click or interact with them.
User and Publisher Perspectives
Users and publishers have mixed responses:
- Some users appreciate direct answers without scrolling.
- Publishers are concerned about traffic loss, as studies show significant drop-offs in CTR when AI Overviews are present.
- Legal challenges and industry pressure have emerged, including lawsuits and regulatory complaints aimed at how AI Overviews impact content owners’ traffic and revenue.
This tension highlights the balance Google must strike between user convenience and the broader health of the web ecosystem.
Conclusion:
The emergence of engagement-driven AI Overviews signals a new era in search where user behavior heavily influences what appears in the SERP.
For content creators and SEO professionals, this means:
- Prioritize engaging content that encourages interaction
- Understand that traditional click metrics may decrease
- Focus on visibility and authority signals, not just CTR
As AI search evolves, focusing on helpful, high-value content becomes even more crucial — especially as Google’s AI Overviews continue to adapt based on engagement.
