Google Expands AI-Powered Search Ads Internationally as Core Revenue Growth Decelerates

Google is officially taking its advertisements in generative AI-powered search experiences into international markets, placing a high-stakes bet that artificial intelligence can unearth fresh monetization opportunities. This strategic expansion arrives as growth within the tech giant’s traditional, foundational search advertising business begins to cool down.

The announcement was delivered on Wednesday during Alphabet’s third-quarter earnings call. Alongside the rollout of international AI ads, Alphabet reported overall revenues of $127.6 billion, marking a robust 25% increase year-over-year. However, a closer look at the financial breakdown revealed that Search advertising growth continued to slow down sequentially, triggering an 8% slide in Alphabet shares following the report’s publication.

The deceleration places mounting pressure on Google executives to transform their expanding suite of artificial intelligence features into a reliable, high-yielding engine for digital advertising. As traditional search models mature, the integration of generative AI into everyday user experiences is no longer just a technological showcase; it has become a fundamental business imperative designed to protect and expand profit margins.

Scaling AI Overviews and Multi-Turn Ad Formats

Google is moving swiftly to capitalize on its user base’s evolving search habits. According to Philipp Schindler, Google’s chief business officer, the company is scaling high-stakes, high-quality ads within AI Overviews in AI Mode to a broader audience of users and queries.

“We are now scaling high-quality ads within AI overviews in AI mode to more users and queries,” Schindler stated during the investor call. “This includes taking our monetization footprint global for the first time. Today, we’re announcing the expansion of ads in AI mode into international markets alongside multi-turn ads and AI mode in the U.S.”

Early performance indicators suggest that these novel ad formats are resonating well with consumers without causing friction. Schindler noted that click-through rates for sponsored product listings embedded within AI Mode are already proving to be comparable to traditional organic search listings. Furthermore, internal user research indicates that consumers perceive these AI-driven advertisements as contextually relevant and helpful rather than intrusive.

This latest international rollout builds heavily on Google’s foundational announcements from earlier in the year. Back in May, during the annual Google Marketing Live event, the company unveiled a series of Gemini-powered ad formats. These included conversational discovery ads—which dynamically respond to complex, multi-layered user queries—and seamlessly integrated sponsored recommendations woven directly into AI-generated answers.

Shifting User Habits and Multimodal Search Explosion

Behind the scenes, generative AI is fundamentally altering how people interact with the world’s most popular search engine. Alphabet CEO Sundar Pichai highlighted during the earnings call that search queries grew at their fastest year-over-year rate in five years, though he stopped short of disclosing the exact percentage of growth.

Pichai credited this surge directly to generative AI features, which are encouraging users to formulate longer, more detailed, and deeply complex questions. On average, queries processed in AI Mode are three times longer than traditional, keyword-based searches.

Moreover, user behavior is rapidly diversifying beyond standard text. One in five AI Mode searches globally now involves voice inputs, images, or document uploads. Demonstrating the sheer scale of this visual shift, Google’s platform has officially surpassed 50 billion visual searches per month.

“[Search] is bringing the benefits of AI to more people than any other product in the world,” Pichai told investors during the briefing. “People are using our AI features more, searching in entirely new ways. Their queries are longer, personalized, and multimodal.”

Financial Breakdown of Alphabet’s Q3 Performance

Despite the deceleration in core search advertising, Alphabet’s wider business ecosystem displayed remarkable resilience and diversification during the third quarter. The Google Services division, which encompasses traditional Search, YouTube, hardware, and other consumer offerings, generated $96.3 billion in revenue, reflecting an 11% increase compared to the same period last year.

Google Search revenue specifically grew 12% year-over-year in the third quarter. While impressive by most corporate standards, this figure represents a noticeable slowdown when compared to previous quarters. Search revenue grew by 17% year-over-year in the second quarter and 19% in the first quarter of the fiscal year.

In stark contrast to the moderating growth in advertising, Google Cloud experienced explosive expansion. Cloud revenue surged by an astounding 103% year-over-year, reaching $30.7 billion. This massive leap underscores the surging enterprise demand for cloud computing infrastructure and enterprise-grade artificial intelligence solutions.

A Transformative Quarter for Google’s Hardware and AI Ecosystem

The third-quarter financial results cap off a remarkably busy and transitional period for Google on both the software and hardware fronts. Over the past few months, the company has aggressively pushed its AI ecosystem deeper into the mainstream consumer market.

In late September, Google released Gemini 4 Argon, which the company hailed as its most powerful artificial intelligence model to date. Concurrently, the consumer-facing Gemini app experienced viral adoption, surging past one billion monthly active users by August. On the hardware side, Google attempted to cement its mobile AI ecosystem with the domestic and international rollout of its Pixel 11 smartphone lineup, which features tight, native integrations with the Gemini assistant.

Implications and Market Analysis

The market’s lukewarm reception to Alphabet’s earnings—evidenced by the 8% drop in share price—highlights a central anxiety among Wall Street investors: the costly transition from traditional, high-margin text ads to resource-intensive generative AI experiences.

For decades, Google’s business model relied on a straightforward formula of matching short-tail text keywords with sponsored links. Generative AI, however, requires immense computational power and changes the user journey from a transactional directory to a conversational advisory service. By introducing ads into AI Overviews and internationalizing these formats, Google is attempting to prove that conversational search can be just as lucrative—if not more so—than the classic search engine results page.

As Google scales these monetization efforts across international borders, competitors in the search and artificial intelligence space will be watching closely. The success or failure of multi-turn AI ads will likely set the benchmark for how the entire digital advertising industry adapts to the generative AI era, proving whether chat-based interfaces can successfully support a multi-billion-dollar ad economy.
