AI Overviews now appear in nearly 25% of searches, while zero-click behavior and declining organic CTRs are reshaping traditional SEO. At the same time, platforms like ChatGPT are driving billions of prompts daily and sending growing referral traffic to websites.
AI Overviews now appear in roughly one out of every four Google searches, accelerating a trend marketers have been watching for years: fewer clicks, more zero-click searches, and shrinking control over how audiences.
Key AI SEO Statistics
AI is increasingly shaping how users find information and reducing reliance on traditional organic search clicks.
1. AI Overviews now appear in 25% of global searches.
2. Informational searches trigger AI Overviews 99% of the time.
3. AI Overviews reduce organic click-through rates by up to 58%.
4. 92-94% of AI Mode searches end without external clicks.
5. ChatGPT now processes roughly 2.5 billion prompts every day.
6. AI-referred retail traffic surged 693% year-over-year during the holidays.
AI Overviews Statistics
AI Overviews are rapidly expanding across global search, changing how users access information and making it important to adapt content strategies to maintain visibility.
7. Alphabet reported that 2 billion monthly users now interact with AI Overviews across 200+ countries and 40 languages, giving the feature one of the widest global rollouts in search history.
AI Overview visibility varies significantly depending on the query set being analyzed. Broad studies that examine all search types tend to report lower visibility rates, while studies focused on informational or question-based searches show much higher adoption.
8. Conductor found that AI Overviews appeared in 25.11% of all analyzed searches in Q1 2026, based on 21.9 million queries. This figure is one of the broadest estimates because it includes multiple search intents rather than focusing solely on informational searches.
9. Some category-specific US studies reported visibility rates as high as 48%, according to BrightEdge. These higher figures reflect query sets that are more likely to trigger AI-generated answers rather than the overall search landscape.
AI Overview visibility varies significantly depending on the query set being analyzed. Broad studies that examine all search types tend to report lower visibility rates, while studies focused on informational or question-based searches show much higher adoption.
10. Ahrefs’ analysis of 146 million SERPs showed that 57.9% of question-based queries display an AI Overview.
11. AI Overviews now dominate informational search results, appearing in 99.9% of purely informational keywords, with 46% tied to long-tail searches containing 7+ words.
12. AI Overviews appear in only 7.9% of local searches, showing Google still treats location-based intent differently from informational queries.
13. According to Digital Bloom, AI Overview coverage grew from ~6.49% to ~48% in roughly a year, suggesting a possible rise to 70-80% of eligible queries by the end of 2026.
Taken together, the studies suggest that roughly one-quarter of all searches currently display AI Overviews, while informational and question-driven searches experience far higher coverage rates.
Sectors Most Impacted By AI Overviews
AI Overviews appear about 8.6× more often in informational sectors like Science and Health than in transactional sectors like Shopping and Real Estate. This shows Google prioritizes knowledge-based queries over purchase-intent searches.
14. According to Ahrefs data, expertise-driven sectors have 3.7× higher AI Overview presence than dynamic sectors such as News and Sports, suggesting that AI performs best when information is stable, authoritative, and less time-sensitive.
The table below shows which sectors generated the majority of AI queries:
| Sector | AI Queries % |
|---|---|
| Science | 43.60% |
| Health | 43.00% |
| Pets & Animals | 36.80% |
| People & Society | 35.30% |
| Internet & Telecom | 30.30% |
| Reference | 30.10% |

The sector breakdown reveals that AI Overviews are not expanding evenly across search. Industries built around factual, evergreen information, such as health, science, and education, are seeing far greater AI visibility than sectors where information changes rapidly, or transactions occur directly on search results.
Businesses in knowledge-driven industries face the highest risk of traffic displacement and may need to prioritize AI citation visibility alongside conventional SEO.
15. Organic CTR plummeted 25% (from 3.2% to 2.4%) for queries with AI Overviews. Paid CTR climbed up 11% (from 14.6% to 16.2%) on the same AI Overview queries, as reported by Seer Interactive.
16. AI Overviews reduce organic CTR for position #1 by up to 58%, according to Ahrefs. The traditional reward for ranking first is shrinking.
17. Position #2 can lose as much as 50.8% of its clicks, while lower rankings see progressively smaller declines. AI Overviews appear to absorb traffic that once flowed to the top of the organic results page.
Have a look at the CTR impact by position due to AI overviews:
| Position in search results | Clickthrough rate impact |
|---|---|
| 1 | -58.00% |
| 2 | -50.80% |

AI SEO Statistics By Country
AI Overview visibility varies significantly across countries and languages, making localization and market-specific search behavior critical for understanding global AI search adoption.
Ahrefs found significant differences in AI Overview visibility across countries, with several Southeast Asian markets leading adoption.
The US sits 13th with coverage at 20.5%.
40. Indonesia turned more than 1 in every 3 tracked searches into generated summaries, the highest share among all countries listed.
41. India recorded the biggest footprint overall, with 8 million generated AI summaries spread across 30 million tracked keywords, the biggest in absolute terms.
42. Japan matched Brazil with a 25% coverage rate, despite tracking 3 million fewer keywords.
43. Nigeria crossed a 26% coverage rate with just 1.6 million tracked keywords, outperforming several larger search markets.
AI Overview visibility varies widely by country, with several Southeast Asian markets showing significantly higher adoption rates than larger search markets such as the United States.

|---|---|---|---|---|
| 1 | Indonesia | 11 million | 4.1 million | 37.20% |
| 2 | Philippines | 6.4 million | 1.9 million | 29.10% |
| 3 | Mexico | 12 million | 3.5 million | 29.10% |
| 4 | India | 30 million | 8.0 million | 26.80% |
| 5 | Nigeria | 1.6 million | 423.0 k | 26% |

The country-level differences suggest that AI search adoption is influenced by more than market size alone.
Several emerging markets show higher AI Overview penetration than larger, mature search markets, indicating that Google’s rollout and user behavior vary significantly by region.
This makes country-specific SEO monitoring increasingly important, as AI visibility trends in one market may not reflect what happens elsewhere.
AI Overviews Share By Languages
