A new SE Ranking study finds that almost one in three U.S. commercial searches in Google’s AI Mode now display text ads. High-cost keywords are far more likely to trigger ads, but paid placements rarely boost organic rankings or citations.
Text ads are now appearing in 29.45% of commercial queries on Google’s AI Mode, according to fresh data from SE Ranking. The study, which examined 50,032 U.S. commercial keywords where text ads could be shown (excluding product carousels), highlights how quickly ad adoption has accelerated since Google began integrating ads into AI-generated search results in late 2025.
By June 30, 2026, nearly one in three commercial searches in the dataset included at least one text ad in the AI Mode response. SE Ranking notes that the true ad rate could be even higher, as AI Mode results can vary between sessions.
Most ad blocks in AI Mode featured more than one advertiser. The analysis found that 71.1% of ad-triggering queries displayed two ads together, while 28.9% showed only a single ad.
Cost-per-click (CPC) emerged as the strongest predictor of ad presence. For keywords with CPCs below $2, ads appeared 24.33% of the time. That rate climbed to 32.45% for keywords with CPCs between $2 and $10, and jumped to 53.56% for those at $10 or higher. In contrast, search volume and keyword difficulty did not show a similar correlation with ad frequency.
Ad frequency also varied widely by category. The pets niche saw the highest ad rate, with ads on 72.38% of analyzed keywords, while healthcare had the lowest at just 2.64%. Higher-ad categories tended to be lead-generation markets with clear conversion paths, while lower-ad categories were often informational or YMYL (Your Money or Your Life) topics, where Google may exercise more caution or commercial demand is lower.
Despite the prevalence of ads, advertisers rarely gained additional visibility as cited sources in AI Mode responses. Only 11.53% of advertiser domains were cited for the keywords they advertised on, and at the URL level, the overlap dropped to just 1.95%. This pattern held even when comparing advertisers to similar non-advertising domains based on domain strength and organic visibility.
Organic ranking overlap was also limited. Just 2.32% of advertised URLs ranked organically for the same queries where their ads appeared, and only 15.35% of advertiser domains ranked organically for those keywords. According to the study, about 85% of advertisers did not appear in organic results for the keywords where they bought AI Mode ads.
The findings suggest that buying AI Mode ads does not increase the likelihood of being cited as a source or ranking organically. Instead, SE Ranking recommends treating AI Mode ads, cited sources, and organic rankings as distinct visibility channels.
SE Ranking’s analysis covered 20 commercial niches, averaging 2,500 keywords per niche. The company cautions that ad behavior may shift as Google continues to roll out new AI-specific ad formats. For comparison, the challenges of monetizing AI-driven search are also evident in the chatbot space, as seen in forecasts for ChatGPT’s ad revenue growth.
Google, founded in 1998 and now a subsidiary of Alphabet Inc., remains the dominant search engine in the U.S. with over 90% market share. The company reported $224 billion in ad revenue for 2025, with ongoing investments in AI-powered search and advertising formats shaping the future of digital marketing.
