What Are AI Overviews?
AI Overviews (formerly called Search Generative Experience or SGE) are Google's AI-generated summaries that appear at the top of search results for certain queries. They synthesize information from multiple web sources to provide direct answers, with expandable cards showing the source websites.
Key characteristics:
- Launched to US users in May 2024
- Expanding globally through 2025-2026
- Appears for ~15-30% of queries (varies by category)
- Sources cited with expandable preview cards
AI Overviews represent Google's response to ChatGPT and Perplexity—bringing AI-generated answers directly into the world's largest search engine.
How AI Overviews Work
Generation Process
- Query analysis - Google determines if AI Overview is appropriate
- Source selection - Relevant pages identified from index
- Information extraction - Key facts pulled from multiple sources
- Synthesis - AI generates cohesive answer
- Citation display - Source cards shown alongside answer
AI Overview Anatomy
A typical AI Overview includes:
- Summary text - AI-generated answer (usually 100-300 words)
- Source cards - 3-5 expandable website previews
- Related questions - Follow-up queries users might explore
- "Show more" option - Expanded answer for complex topics
When AI Overviews Appear
AI Overviews trigger for specific query types:
| Query Type | Likelihood | Example |
|---|---|---|
| Informational "what is" | High | "What is generative AI" |
| How-to questions | High | "How to start a podcast" |
| Comparison queries | Medium | "React vs Vue for beginners" |
| Local queries | Low | "Best pizza near me" |
| Transactional | Very Low | "Buy running shoes" |
| Navigational | Very Low | "Facebook login" |
Google avoids AI Overviews for YMYL (Your Money Your Life) topics like medical advice, financial decisions, and legal matters—though this is evolving.
Impact on SEO and Traffic
The Zero-Click Challenge
AI Overviews increase zero-click searches:
- Users get answers without clicking through
- Some studies show 25-40% click reduction for affected queries
- Long-tail informational queries most impacted
The Citation Opportunity
Being cited in AI Overviews provides value:
- Brand visibility even without clicks
- Perceived authority association
- Potential for clicks via source cards
- Influence on related queries
Traffic Redistribution
AI Overviews change traffic patterns:
- Featured snippet owners may lose traffic
- Multiple sites get exposure (vs. one snippet winner)
- Lower-ranking pages can get AI Overview citations
- Domain authority still matters for source selection
AI Overviews vs. Featured Snippets
| Aspect | AI Overview | Featured Snippet |
|---|---|---|
| Content source | Multiple sites | Single site |
| Generation | AI-synthesized | Extracted verbatim |
| Length | 100-300+ words | 40-60 words typical |
| Control | Limited | More predictable |
| Position | Above all results | Position zero |
| Citations shown | 3-5 sources | One source |
Optimizing for AI Overviews
Content Structure
Google's AI extracts information best from well-structured content:
Effective patterns:
- Clear H2/H3 heading hierarchy
- Bullet points and numbered lists
- Tables for comparisons
- FAQ sections with direct answers
- Definition paragraphs early in content
Example structure:
## What is [Topic]?
[2-3 sentence definition]
## How [Topic] Works
[Step-by-step or explanation]
## Key Benefits of [Topic]
- Benefit 1
- Benefit 2
- Benefit 3
Authority Building
AI Overviews favor authoritative sources:
- Established domains with topical coverage
- E-E-A-T signals (expertise, experience, authority, trust)
- Quality backlinks from relevant sites
- Consistent publishing in topic area
Comprehensive Coverage
To be selected as a source:
- Cover topics thoroughly (not thin content)
- Answer related questions on the same page
- Include specific facts, numbers, and examples
- Update content regularly for freshness
Technical Requirements
Ensure your content is eligible:
- Allow Googlebot crawling (no blocks in robots.txt)
- Fast page load times
- Mobile-friendly design
- Proper semantic HTML structure
Tracking AI Overview Citations
Manual Monitoring
- Search target queries in Google

- Expand source cards to see citations
- Note which domains appear
Limitations
Currently, no reliable automated tracking exists for AI Overview citations:
- Google Search Console doesn't separate AI Overview impressions
- Third-party tools have limited accuracy
- Manual checks remain most reliable
What to Monitor
Track changes in:
- Impressions for informational queries
- Click-through rates (may decrease if cited in AI Overview)
- Branded search volume (visibility may drive brand searches)
- Referral traffic from Google
The Future of AI Overviews
Google continues expanding and refining AI Overviews:
- Rolling out to more countries and languages
