Google’s AI-powered search features are becoming increasingly common, with new research indicating that AI-generated responses now appear in a much larger share of search queries than they did just a year ago.
According to data from Similarweb’s Generative AI Landscape report, AI Overviews were displayed in approximately 43% of U.S. Google searches, highlighting the company’s continued push toward AI-assisted search experiences.
AI-powered search continues to evolve
Google now offers two primary AI search experiences. AI Overviews provide concise summaries directly within traditional search results, while AI Mode delivers a conversational interface that allows users to ask follow-up questions without starting a new search.
To generate these responses, Google uses a technique known as query fan-out. Rather than performing a single search, the system breaks complex questions into multiple related topics, gathers information from several searches, and combines the findings into a unified response with supporting links.
Search behavior is changing
The growth of AI-powered search is also influencing how people interact with search engines.
Similarweb reported significant growth in traffic to Google’s AI Mode, while Google has separately stated that the feature has surpassed one billion monthly users. Although the two datasets measure different metrics, both point toward rapid adoption of conversational search experiences.
Researchers also found that users are submitting longer and more natural-language queries. Instead of relying on short keyword phrases, many people are asking complete questions similar to prompts used with AI chatbots.
This shift allows Google to better understand user intent and provide richer answers without requiring users to repeatedly refine their searches.
Generative AI usage keeps growing
The report also highlights continued expansion across the broader generative AI market.
Between mid-2025 and mid-2026, generative AI platforms averaged roughly 9.5 billion monthly visits. Monthly unique visitors and mobile app downloads also increased substantially, reflecting continued consumer interest in AI-powered services such as ChatGPT, Gemini, Claude, and Perplexity.
Interestingly, the research suggests that AI services are complementing traditional search rather than replacing it. Many ChatGPT users continue to rely on Google, while significant overlap exists among users of multiple AI platforms.
Publishers remain concerned
As AI-generated answers become more prevalent, publishers continue to question how these features affect website traffic.
When users receive complete answers directly within search results, they may be less likely to visit the original source. In response, Google has introduced several updates that make external sources more visible within AI Overviews and AI Mode, including improved article previews and more prominent links.
However, Google has not released data showing whether these changes have significantly increased referral traffic to publishers.
ChatGPT citations are increasing
Similarweb’s report also examined how frequently ChatGPT references external websites when generating responses.
The percentage of responses containing web citations increased more than fivefold over the past year. Citation rates were especially high in industries where information changes frequently, including travel, retail, and sports.
The study also found that AI systems often cite detailed internal pages while users are more likely to click through to a company’s homepage, highlighting a difference between the pages used as information sources and the pages users ultimately visit.
Cloudflare explores new publisher protections
As AI companies continue collecting information from the web, publishers are also experimenting with new ways to control access to their content.
Cloudflare is currently testing a Pay per Crawl service that would allow website owners to charge AI crawlers for accessing their content. The system enables publishers to permit, restrict, or monetize AI crawling, potentially creating a new revenue model as AI-generated search becomes increasingly common.
The company has also expanded its AI Crawl Control tools, allowing publishers to provide licensing information or payment requirements directly to AI crawlers through configurable HTTP responses.
AI search continues reshaping the web
The latest findings illustrate how rapidly AI is transforming the search landscape. As conversational search becomes more widely adopted, both users and publishers are adapting to new ways of discovering and sharing information online.
While AI-generated summaries offer greater convenience for users, they also introduce new challenges around website traffic, attribution, and content monetization. How search engines, AI providers, and publishers respond to these changes will play a significant role in shaping the future of the open web.
