Adthena analyzed 10 million SERPs to show where brands are losing ground and how fast.Google’s introduction of AI Overviews is radically reshaping the search landscape. For advertisers, the shift has serious implications: less visibility, fewer clicks, and more uncertainty.
With the rise of generative search, paid placements and organic listings are increasingly pushed down the page, disrupting search marketing strategies.
At Adthena, we’ve conducted a data study to understand the true impact of these changes across five core verticals: Retail, Travel, Finance, Healthcare, and Automotive. Combined with customer insights and real search results data, this blog outlines what advertisers need to know and how they can adapt.
What are AI Overviews and why they matter
AI Overviews are Google’s new generative responses to search queries. They appear prominently on the search engine results page (SERP), often at the very top, summarizing answers using a blend of AI-generated content and web citations. These responses differ from traditional features like featured snippets or knowledge panels:
Featured snippets pull directly from a single source.
Knowledge panels rely on structured data.
AI Overviews synthesize multiple sources in real-time.
Their position on the page makes them powerful, but also disruptive. Ads and organic listings are often pushed below the fold, forcing advertisers to rethink how they maintain brand visibility.
The visibility shift: How paid ads are being displaced
As AI Overviews dominate Google’s search results, traditional ad placements are being crowded out, which means:
Fewer ad slots sitting above the fold.
Organic results remain visible but can lose attention and clicks.
Fragmented user journeys.
Impact on Google Ads performance and auction dynamics
Click-through rates and ad engagement drop
As AI Overviews capture more user attention, fewer users scroll to traditional ad placements, leading to:
Lower CTRs for key terms.
Lower Quality Scores over time.
Cost-per-click and competitive pressure
The scarcity of premium placements is likely to lead to increased bidding activity:
Higher CPCs to secure visibility.
Volatility in auction performance.
Industry examples: Who’s most affected
Some verticals are seeing more dramatic changes than others. Here’s a breakdown based on our data:
Retail
Shopping ads are frequently pushed below AI-generated content, reducing above-the-fold visibility.
Achieving dual presence in both ads and SEO is still possible, but dominating search results is far more difficult.
Travel
Planning and advice queries often trigger AI Overviews, showing in addition to both ads and organic content.
Longer-tail queries like “best family holidays in Greece” now surface AI content first.
Finance
AI Overviews are cautiously emerging, driven entirely by generic, informational, and top-funnel queries.
No branded terms triggered AI Overviews, indicating brand searches remain largely unaffected, for now.
Healthcare
AI Overviews dominate informational searches like “what is [drug name] used for?”
Automotive
AI-generated car comparison content is moving the buyer journey higher up the SERP.
What the data shows: Adthena’s Search Intelligence
To understand the real impact of Google’s AI Overviews, Adthena’s data science team analyzed more than 10.4 million SERPs across a five-day period. This snapshot reveals how AI Overviews are shaping search results in key global markets, including the U.S., the UK, Australia, and the EU.
We examined 450,000 search terms from 25 global enterprise brands across five key industries: Retail, Travel, Finance, Healthcare, and Automotive.
Our goal was to uncover:
How often AI Overviews are triggered.
What types of queries are most likely to prompt them.
Whether AI Overviews appear more frequently on branded or generic searches.
This chart breaks down search queries by industry and query length, showing the percentage that trigger an AI Overview (green) versus those that don’t (blue).
A clear pattern stands out: the longer the search term, the more likely it is to trigger an AI Overview – almost a linear trend.
For example, Retail and Travel rarely see AI Overviews unless the term is fairly long. Meanwhile, Healthcare is already highly saturated with AI Overviews across term length, even for short search terms.
This heatmap shows how often AI Overviews appear across various industries, based on the length of the search query. It breaks down the percentage of searches that trigger an AI Overview depending on how many words are in the search term.
For example, longer search queries tend to trigger AI Overviews more frequently, especially in industries like Healthcare, where even shorter queries often generate these summaries.
The data shows that:
Across all industries, longer-tail queries tend to trigger AI Overviews more often.
While this is true across all industries, retail sees the highest frequency of AI Overviews on the longest terms.
Healthcare stands out with higher AI Overview presence across various query lengths.
Looking at AI Overview frequency by industry, we note:
Healthcare leads with AI Overviews appearing nearly 50% of the time.
Financial Services follows at 29.2%, followed by Automotive at 15.8%.
Retail and Travel have the fewest AI Overviews, at 7.8% and 4.6% respectively.
This shows that some industries, especially Healthcare, are seeing AI-generated answers much more often and earlier than others.
Looking at AI Overviews brand versus generic term split, we note:
In Financial Services, 29.2% of generic searches show AI Overviews, but none appear on brand searches.
In Retail and Travel, AI Overviews only show up on generic searches, not on brand terms.
Healthcare is different: It has the highest AI Overview presence overall, with 39.6% of brand searches also showing AI summaries, the highest of any industry.
This means Healthcare faces a unique challenge: even branded searches are getting AI-generated summaries, which could affect how brands control their message and accuracy in search results.
