Google expands AI Search ads globally as core ad growth slows

Google is expanding the geographic reach of advertising inside its AI-powered Search experiences. The biggest change is that ads in AI Mode are moving beyond the United States into international markets. This matters because Google’s traditional Search advertising growth is slowing, creating pressure to make AI Search commercially useful.

The expansion covers high-quality ads within AI Overviews and AI Mode. It also includes multi-turn ads, which can continue across a conversational exchange, and sponsored product listings that appear alongside AI-generated answers. Google says these formats are being shown to more users and for more queries.

This is an early monetization push, not a fully disclosed global rollout by country or advertising revenue total. Google says sponsored product listings in AI Mode already have click-through rates comparable to organic listings. The company is also testing whether users find the ads relevant as AI Search changes how people ask questions.

AI Overviews are AI-generated summaries that appear within Google Search and provide an answer before or alongside traditional results. AI Mode is a more interactive experience designed for follow-up questions and multi-turn conversations. Both aim to answer questions directly, rather than relying only on a page of ranked links.

The article highlights the behavioral difference. Queries in AI Mode are three times longer on average than traditional searches. One in five AI Mode searches globally uses voice, images, or documents. These features let people ask more detailed questions and use more than typed text when searching.

Traditional Search remains part of the broader experience, but AI features change how users interact with it. Google says Search queries reached their fastest year-over-year growth in five years. The article does not provide a precise technical definition of each interface, but it links AI features to longer, personalized, and multimodal searches.

Sponsored product listings are commercial results integrated into AI Mode, where Google generates an answer to a user’s query. Conversational discovery ads are another format that responds to users’ questions during a more interactive search exchange. Both place advertising closer to the answer itself.

Google introduced these formats as Gemini-powered advertising products. They include sponsored recommendations integrated into AI-generated answers and ads that respond to questions conversationally. The mechanism is therefore tied to the user’s query and the generated response, rather than being limited to a separate advertising section on a conventional results page.

The article does not describe the exact ranking rules, labels, or payment model for these placements. It does report early performance: sponsored product listings in AI Mode have click-through rates comparable to organic listings. Google’s user research also suggests people consider the ads relevant, supporting further expansion.

The article does not give a separate dollar figure for Google Search advertising. It reports that Google Services, the division containing Search, generated $96.3 billion in third-quarter revenue, up 11% year over year. That figure includes more than Search, so it should not be treated as Search advertising alone.

The growth trend is clear. Google Search revenue grew 19% year over year in the first quarter, then 17% in the second quarter, and 12% in the third quarter. The third-quarter decline represents a sharp deceleration from the beginning of the year. Alphabet’s total revenue still rose 25% to $127.6 billion.

The slowdown helps explain Google’s focus on AI monetization. The company is expanding ads in AI Overviews and AI Mode while reporting strong user engagement with new search formats. Alphabet shares fell 8% after the results, showing that investors reacted negatively despite overall company growth.

Search advertising has long been a major part of Google’s business, but its growth is losing momentum. Search revenue growth fell from 19% in the first quarter to 12% in the third. That makes it more important for Google to turn growing AI usage into additional commercial activity instead of allowing AI features to weaken the value of existing Search ads.

Google is responding by placing ads inside AI Overviews and AI Mode. It is also testing sponsored product listings, conversational discovery ads, and multi-turn ads. These formats connect advertising with longer and more complex queries. Early click-through rates for sponsored product listings in AI Mode are comparable to organic listings.

The article does not state a specific failure scenario if monetization does not work. It does show the immediate pressure: Alphabet reported strong overall revenue, yet Search growth slowed and shares fell 8%. Without successful AI monetization, Google would remain more dependent on its slowing traditional Search advertising business.

Alphabet could rely on businesses beyond traditional Search ads and advertising inside AI Search. The clearest alternative in the article is Google Cloud, whose third-quarter revenue surged 103% to $30.7 billion. That growth gives Alphabet another expanding business while Search advertising growth slows.

Google Services generated $96.3 billion in the quarter, but the article does not break that total into individual businesses. The company also reported that the Gemini app had reached 1 billion monthly users and launched its Pixel 11 lineup. Those products show wider activity, though the article does not say how much revenue they generate or how they are monetized.

The article therefore identifies alternatives but does not rank them as replacements for Search advertising. Cloud is the only separately reported major revenue source outside the broader Services figure. Gemini and Pixel may support Alphabet’s product ecosystem, but their financial contribution and future role are not stated.

Search advertising connects a user’s query with a paid result or recommendation. Advertisers typically pay when people click an ad, while Google uses the query and context to show commercial messages that may be useful. The article does not explain the exact billing system, but it reports click-through rates as an important performance measure.

Longer and more specific queries can reveal what a person wants, where they are in a decision, and which product might fit. Multimodal searches add signals from voice, images, or documents. Google says AI Mode queries are three times longer than traditional searches, and one in five AI Mode searches globally uses those additional formats.

These behaviors create more places for relevant advertising inside AI answers and conversations. Google says sponsored product listings in AI Mode already achieve click-through rates comparable to organic listings. The opportunity is substantial, but the article does not provide an advertising revenue forecast or say how much these formats earn today.
