AI Overviews: What They Are and Why They Appear in Nearly Half of Google Searches
Quick Answer
Google AI Overviews are AI-generated summaries that appear at the top of search results, providing direct answers by synthesizing information from multiple web sources. They now appear in nearly half of all Google searches, fundamentally changing how users consume information and how websites earn traffic.
You search for "best laptop for video editing" on Google.
But instead of the familiar blue links, you see something different at the top.
A large box with a synthesized answer. Specific laptop recommendations. Specs comparison. All generated by AI, sitting above the traditional search results.
This is an AI Overview. And it's changing everything about how search works.
What Are Google AI Overviews?
Google AI Overviews (previously called Search Generative Experience or SGE) are AI-generated responses that appear at the top of Google search results.
Unlike traditional featured snippets that pull a direct quote from a single source, AI Overviews:
- 1. Synthesize information from multiple sources across the web
- 2. Generate original text that summarizes and answers the query
- 3. Include source citations as small links users can click
- 4. Push traditional results further down the page
Think of it this way: Traditional search showed you 10 doors and said "the answer is behind one of these." AI Overviews read what's behind all the doors and summarize the answer for you.
How Common Are AI Overviews? (The Data)
85%+
Informational Queries

Higher for "how to" questions
The rollout has been aggressive. Google started testing AI Overviews in May 2023, expanded to all US users by May 2024, and has been rolling out globally since.
Query types most likely to trigger AI Overviews:
- • "How to" questions (85%+ trigger rate)
- • "What is" definitions (75%+ trigger rate)
- • Product comparisons (60%+ trigger rate)
- • Health and medical queries (70%+ trigger rate)
- • Technical explanations (80%+ trigger rate)
If your content targets informational queries, AI Overviews are almost certainly affecting your traffic.
How Do AI Overviews Actually Work?
Understanding the mechanics helps you optimize for them.
How AI Overviews Generate Answers
- 1
Query Analysis
Google's AI interprets your search intent
- 2
Source Retrieval
AI pulls from top-ranking pages and authoritative sources
- 3
Synthesis
Information is combined into a coherent answer
- 4
Citation
Source links are added for users who want more detail
The key insight: AI Overviews don't just quote your content. They understand it, extract the relevant parts, and weave them into a larger answer alongside other sources.
This means the old SEO goal of "rank #1 and get 30% of clicks" is outdated. Even position #1 can get bypassed if the AI Overview answers the query completely.
The Impact on Website Traffic
Here's what website owners are experiencing:
-34.5%
CTR decline when AI Overviews appear (Ahrefs)
76%
of citations from top 10 rankings (Ahrefs)
4.4x
higher conversion from AI traffic (Semrush)
The silver lining: While total click volume drops, users who do click through from AI Overviews are more qualified. They've already read a summary and want more depth. That's why the conversion rates are higher.
The challenge is getting cited in the first place. And that requires a new optimization approach called Generative Engine Optimization (GEO). (See our complete guide to GEO vs AEO vs SEO.)
How to Optimize for AI Overviews
You can't guarantee placement in AI Overviews. But you can significantly increase your chances.
1. Answer-First Content Structure
Put your answer in the first 2-3 sentences. Don't bury the lead. AI extracts from the top.
2. Comprehensive Coverage
Cover the topic thoroughly. AI prefers sources that address multiple aspects of a query.
3. Structured Data
Use clear headings, lists, and tables. AI can parse structured content more easily.
4. E-E-A-T Signals
Demonstrate expertise, experience, and authority. AI prioritizes trustworthy sources.
5. Cite Your Sources
Link to authoritative references. It signals credibility to both users and AI systems.
Key Insight: Traditional SEO focused on ranking. GEO focuses on being cited. The skills overlap but the tactics differ.
Frequently Asked Questions
Can I opt out of AI Overviews?
Not really. Google can use your indexed content for AI Overviews. You can use nosnippet meta tags to prevent snippet extraction, but this also prevents traditional featured snippets, which may hurt more than it helps.
Do AI Overviews replace featured snippets?
They coexist, but AI Overviews appear more frequently and often above featured snippets when both are present. For many queries, AI Overviews are becoming the primary answer mechanism.
Are AI Overviews accurate?
Mostly, but not always. Google has faced criticism for AI Overview errors. However, Google continues to improve accuracy, and users are increasingly trusting these results.

The Story Behind This Post
This post was written in response to the overwhelming number of questions I received about "that AI thing at the top of Google." AI Overviews became so common that non-technical users noticed the change—but didn't understand what it meant for their businesses.
The challenge was balancing comprehensiveness with accessibility. I wanted to explain the mechanics (how AI Overviews work) while keeping it practical (what you should do about them). Three drafts later, this is the version that strikes that balance.
Every statistic verified through Search Engine Journal, Ahrefs, and Semrush primary sources. Screenshots captured using stealth mode to avoid CAPTCHA issues.
