Google AI Mode serves text ads on 29% of commercial keywords, with high‑CPC queries most likely to see ads and most advertisers not cited as sources.
Google AI Mode returned a text ad on 29% of the 50,032 commercial keywords examined, and in 88% of those cases the advertiser’s domain did not appear among the AI‑cited sources [2].

|---|---|
| Ad frequency | 29% of commercial queries |
| High‑CPC ad presence | 53.56% for keywords $10+ |
| Domain citation rate | 11% of ad‑shown domains |
| Niche variance | 72% (Pets) vs 2.6% (Healthcare) |
The SE Ranking analysis split keywords into three cost‑per‑click (CPC) buckets. Ad presence rose from 24.33% on sub‑$2 keywords to 32.45% in the $2‑$10 band, and peaked at 53.56% for keywords priced $10 and above [2]. Search volume and keyword difficulty showed no comparable trend, indicating that AI Mode’s ad placement follows commercial value signals rather than query popularity.
Ad appearance varied dramatically by vertical: Pets keywords showed ads on 72.38% of queries, while Healthcare keywords saw ads on only 2.64% [2]. SE Ranking also checked whether the advertiser’s domain or exact URL appeared in the AI‑generated source list. The domain was present in just 11% of cases and the exact URL in 1.95% [1]. Consequently, most paid ads do not double as cited references, and only 2% of paid URLs also ranked organically for the same keyword [1].
Across the 14,733 ad‑showing keywords, 2,930 unique advertisers generated 25,243 ad appearances, but distribution was uneven. In high‑ad niches like Pets and Entertainment, a handful of advertisers averaged over 50 appearances each, whereas in low‑ad niches such as Healthcare and News & Politics, advertisers averaged fewer than three appearances [2]. This creates two distinct competitive dynamics: entrenched repeat winners in concentrated markets versus a more open field in fragmented ones.
The data shows AI Mode is evolving from a pure answer engine into a paid‑media channel, with ad placement closely mirroring traditional search‑ad economics. Yet the disconnect between ad slots and source citations means advertisers cannot rely on AI Mode for organic credibility, underscoring the need to treat it as a separate paid avenue while watching for format changes that could merge the two.
