Ads Appear on 29% of Commercial AI Mode Queries — and the Advertiser Usually Isn't a Source

SE Ranking analysed 50,032 commercial keywords across 20 niches — roughly 2,500 per niche, all selected because they trigger a text ad in classic Search — and checked what AI Mode returned. Data was collected on June 30, 2026, reflecting US results.

14,733 of them — 29.45% — returned a text ad.

That number alone is worth knowing. The finding underneath it is more interesting.

The advertiser usually isn't one of the sources

In the queries that showed an ad, the advertiser's domain appeared among AI Mode's cited sources just 11% of the time. The exact advertised URL appeared 1.95% of the time. In the overwhelming majority of cases, the brand paying for placement was not among the pages AI Mode drew its answer from.

Two separate systems are operating on the same screen. One picks sources to ground an answer; the other auctions a placement next to it. They are not informing each other in any way a user could detect.

For advertisers this cuts both ways. Paying for presence in AI Mode does not buy you into the answer — your ad sits beside a synthesis assembled from other people's pages. And for anyone hoping paid spend might nudge organic citation, this is the clearest evidence yet that it doesn't.

Ad presence tracks CPC almost perfectly

The correlation between keyword value and ad presence is strong and linear:

Keyword CPC	Queries showing an ad
Under $2	24.33%
$10 and above	53.56%

On the most expensive commercial terms, better than half of AI Mode responses carry advertising. That's not an experiment at the margins.

71.1% of ad-triggering queries showed two ads in the same response, against 28.9% showing one. Where Google monetises AI Mode at all, it usually does so twice.

Category variation is enormous

This is where the averages stop being useful:

• Pets: 72.38% of analysed keywords showed ads
• Healthcare: 2.64%

A factor of roughly 27 between the top and bottom category. Any statement about "how monetised AI Mode is" that doesn't name a vertical is close to meaningless. If you work in pets, home or retail, this is already your search environment. If you work in healthcare, it barely exists yet — and the YMYL caution that shapes so much of Google's behaviour is the obvious explanation.

SE Ranking also makes a methodological point worth repeating: 29.45% should be read as a floor, not a ceiling. AI Mode is volatile, and the same query can return an ad in one session and nothing in the next. A single-day snapshot undercounts rather than overcounts.

What this changes

Stop treating AI Mode as an organic-only surface. Nearly a third of commercial queries — over half at high CPC — are monetised. Strategy decks still describing AI Mode as the place where ads haven't arrived are describing June 2025.

Check your own vertical before acting. The 29.45% average conceals a 2.64%–72.38% range. Run your own commercial terms and look. The average is not your number.

Don't buy ads expecting citation. An 11% domain overlap and 1.95% URL overlap says the paid and organic layers are independent. If your goal is being in the answer, that's earned through sources, not spend — which is exactly what the GEO citation experiments found from the other direction.

Recalculate what position one is worth. Two ads plus a synthesised answer above your listing is a different page to the one your traffic forecasts assume.

Re-measure periodically. This is a snapshot of one day in a volatile system. Treat it as a well-built baseline, not a constant.

The honest limitation

One collection date, one country, one keyword set chosen specifically because those terms trigger ads in classic Search. That last point matters: this measures how often ad-triggering keywords carry ads in AI Mode, not how often all AI Mode queries do. The right reading is "among commercial queries that would show an ad on a normal SERP, 29.45% also show one in AI Mode" — a precise and useful claim, and a narrower one than the headline suggests.

It remains the most rigorous public measurement of AI Mode monetisation available, and it's a considerably better basis for planning than the anecdotal screenshots that have stood in for evidence until now.
