In a development that marks a significant turning point for the paid search industry, Adthena has announced that it is the first company to detect advertisements appearing inside Google AI Overview search results. The observation signals a potential shift in how Google may monetize generative AI driven search experiences and presents early evidence that the commercial layer of AI powered discovery is beginning to take shape. The ability to identify ads within this environment positions Adthena at the leading edge of visibility and intelligence for brands navigating the future of AI search results.
The announcement is based on analysis conducted across a dataset of twenty five thousand search engine results pages monitored by Adthena. From that sample, the company detected thirteen instances in which ads were served within the AI Overview module, representing an extremely low frequency of zero point zero five two percent but offering the earliest measurable proof of placement in this emerging format. While rare, these discoveries demonstrate how Google may be preparing to introduce paid media into the evolving generative search experience.

According to Adthena, the detected ad units resembled traditional Google text advertisements, containing a blue headline, a short description, and the brand name displayed in place of a URL, but they also featured a thumbnail image related to the search topic. The ads were positioned directly underneath the AI generated overview summary and included a visible Sponsored label. Headline lengths averaged fifty five characters and descriptions averaged eighty five characters, aligning closely with conventional search ad structure while integrating more visual components similar to listings historically associated with product based formats.
The ads appeared across sectors such as education, consumer electronics, retail, telecom, and health. All instances were detected on desktop searches within the United States and none were observed on mobile devices or in international markets.
Phillip Thune, CEO of Adthena, called the discovery a foundational moment for the industry. “This is a pivotal moment for search marketers,” Thune said. “For the first time, we can see ads entering AI generated results. Our mission is to answer the questions that paid search marketers have as ads enter AIOs, a new set of questions emerge and we will be able to provide answers on frequency, which brands appear and do not, and the impact these ads have on overall campaigns. We strive to give brands clarity in every new search environment and today, that extends to the emerging world of ads in AI Search.”

Adthena research indicates that the widespread integration of generative answers into the search results page may have meaningful implications for performance metrics. The company reports that paid search click through rates could fall by eight to twelve percentage points, which equates to a relative decline of roughly twenty to forty percent. Enterprise clients are already using Adthena AI Overview visibility insights to evaluate campaign performance and understand changes to budget efficiency as new interfaces alter user behaviour. The addition of real time tracking for ads inside AI Overviews allows marketers to measure the interaction between paid and organic visibility in the generative interface.
Thune said the discovery reflects the beginning of a new auction environment. “While Google rollout is still limited and clearly in the test phase, this development signals the start of a new auction dynamic,” he said. “Adthena platform is uniquely positioned to help brands adapt monitoring ad frequency, competitive visibility, and ROI as AI driven search evolves.”
The future of AI search results will shape how marketers compete for attention and attribution in a landscape where generative responses take precedence over traditional ranking layouts. Adthena early discovery offers the first proof that paid promotion is entering this environment, signaling profound change to the economics of search and setting the stage for an entirely new model of digital visibility.
