New data from BrightEdge reveals that Google’s AI Overviews is increasingly blocking organic search results. If this trend continues, Google AI Overviews and advertisements could cover well over half of the available space in search results.
Organic Results Blocking Creeping Up
Google’s AI Overviews feature, launched in May 2024, has been a controversial feature among publishers and SEOs since day one. Many publishers resent that Google is using their content to create answers in the search results that discourage users from clicking through and reading more, thereby negatively influencing earnings.
Many publishers, including big brand publishers, have shut down from a combination of declining traffic from Google and algorithmic suppression of rankings. AI Overviews only added to publisher woes and has caused Google to become increasingly unpopular with publishers.
Google AIO Taking Over Entire Screen
BrightEdge’s research shows that AI Overviews started out in May 2024 taking up to 600 pixels of screen space, crowding out the organic search results, formerly known as the ten blue links. When advertising is factored in there isn’t much space left over for links to publisher sites.
By the end of summer the amount of space taken over by Google’s AIO increased to 800 pixels and continued to climb. At this pace BrightEdge predicts that Google could eventually reach 1,000 pixels of screen space. To put that in perspective, 600 pixels is considered “above the fold,” what users typically see without scrolling.

Percentage Of Queries Showing AIOs
The percentage of queries that display Google’s AI Overviews have also been creeping up. Health related search queries have been trending higher than any other niche. B2B Technology, eCommerce, and finance queries are also increasingly showing AI Overview search results.
Healthcare search queries initially triggered AIO at around 70% of the time. Health related queries are now triggered over 80% of the time.
B2B technology queries started out in May 2024 showing AIO results at about 30% of the time. Now those same queries trigger AIO results almost 50% of the time.
Finance queries that trigger AI Overviews have grown from around 5% to 20% of the time. BrightEdge data shows that Google AIO coverage is trending upwards and is predicted to cover an increasing amount of search queries across other topics, specifically in travel, restaurants, and entertainment.
BrightEdge’s data shows:
“Finance shows most dramatic trajectory: starting at just 5.3% but projected to reach 15-20% by June 2025
-Healthcare led (67.5% in June)
-B2B Tech: 33.2% → 38.4%, projected 45-50%
-eCommerce: 26.9% → 35.1%, projected 40-45%
-Emerging sectors showing dramatic growth:
Entertainment (shows, events, venues): 0.3% → 5.2%
Travel (destinations, lodging, activities): 0.1% → 4.1%
Restaurants (dining, menus, reservations): ~0% → 6.0%”
BrightEdge explains that restaurant search query coverage started out small, focusing on long tail search queries like “restaurants with vegetarian food for groups” but is now is rolling out in higher amounts, suggesting that Google is feeling more comfortable with their AIO results and is expected to roll out across more search queries in 2025.
They explain:
“AIO’s evolved from basic definitions to understanding complex needs combining multiple requirements (location + features + context)
