Google AI Overviews Expand Across Nine Industries, Covering Nearly Half of All Queries

New research from BrightEdge shows that Google’s AI Overviews (AIO) continue to grow rapidly, yet traditional organic search results still appear in slightly over half of queries. While AIO is becoming more prominent, it has not fully replaced the classic search experience.

AIO Coverage Grows 58% in One Year

From February 2025 to February 2026, the share of queries triggering AI Overviews increased 58% overall. Key sectors saw dramatic growth:

  • Education: 18% → 83% of queries

  • B2B Technology: 36% → 82%

  • Restaurants: 10% → 78%

  • Healthcare: Already high at 72% in 2024, reaching 88% by December 2025

The high adoption in healthcare aligns with user demand for conversational answers: OpenAI reported that over 5% of all chats are healthcare-related, and 25% of weekly active users search ChatGPT with health queries. A Brookings Institution survey also found that 53% of healthcare professionals use AI.

Industries Leading AIO Growth

The nine industries seeing the most rapid expansion of AI search coverage are:

  1. Healthcare

  2. B2B Technology

  3. Education

  4. Insurance

  5. Entertainment

  6. Travel

  7. eCommerce

  8. Finance

  9. Restaurants

Organic Search Still Holds Slight Majority

Despite AIO’s growth, traditional search results still appear for 52% of queries, meaning AI and classic search are nearly evenly split. High-value sectors, such as B2B, are increasingly moving toward AI-generated answers, while queries in other areas, like restaurants, may reflect content gaps that businesses need to fill.

Search Operates in Two Distinct Modes

Google search now presents results in two primary formats:

  • AI Overviews first: A large, often visually dominant content block above traditional listings

  • Classic organic results: Standard ranked links without AI summaries

This division mirrors a long-standing trend. Since the early 2000s, Google has evolved beyond the “ten blue links,” from local search and Google Maps to Featured Snippets in 2014. Today, AI Overviews represent the latest evolution toward answers-first results.

AI Overviews Reshape the SERP Experience

When AIO appears, it significantly impacts the visual layout:

  • The average AI Overview exceeds 1,200 pixels in height

  • A standard desktop viewport is roughly 900 pixels, meaning the first organic result is below the fold

  • AI Overviews can dominate the visible screen, making traditional links secondary unless users scroll

Key Takeaways

  • AIO is widespread, but traditional search results remain relevant

  • Growth is concentrated in sectors where users benefit from conversational answers

  • AI Overviews can dramatically shift attention away from organic listings, influencing click behavior and engagement

  • Businesses in high-growth sectors may need to optimize content for AI-driven answers to remain visible

AI Overviews Reshape the Search Experience Without Replacing Organic Results

AI Overviews (AIO) does not appear on every query, but when it does, it occupies a large portion of the screen, pushing traditional search results further down. This highlights a shift in user behavior: people are increasingly conditioned to consume conversational answers, signaling a paradigm shift from “search” as a list of links to “search” as answer discovery.

AI Overviews vs. Page One Rankings

A key distinction is how AIO selects sources:

  • Organic search: Ordered by ranking position

  • AI Overviews: Synthesizes information and cites sources, which often differ from the top organic listings

This is driven by Google’s FastSearch, which retrieves the top 3 organic results for multiple queries generated from a single conversational query. These results are then used to create the AI Overview answer.

  • Only 17% of sources cited in AIO appear in the organic top 10

  • High organic ranking does not guarantee citation in AIO, and conversely, low-ranking content can still be cited

  • Broader alignment improves slightly across the top 100 results, but top 10 overlap remains largely flat

In short, AI Overviews visibility is related to organic performance, but it is not interchangeable with page-one ranking. Content creators should treat AIO as a distinct opportunity from traditional SEO.

Growth Continues Alongside Organic Search

BrightEdge’s research shows that AIO coverage has grown 58% year over year, now appearing in nearly half of all tracked queries.

  • The presence of AIO is expanding, but traditional organic results still represent a slim majority of queries

  • Visual dominance of AI content is increasing, dramatically altering the user interface when deployed

  • Understanding which queries still trigger classic search—e.g., local or navigational queries—will be important for future SEO strategy

Key Takeaways

  • AIO dominates the visible screen, influencing how users interact with search results

  • Cited sources in AIO do not mirror top organic rankings, creating a new consideration for content strategy

  • Growth is ongoing, but traditional search remains relevant

  • Publishers should monitor how AIO impacts visibility, particularly for high-value or informational queries
