Google Expands AI Search Advertising Globally as Traditional Revenue Growth Slows

Yesterday 23:00

Google is expanding advertising across its artificial intelligence-powered search services into international markets, seeking to establish new sources of revenue as growth in its traditional search advertising business loses momentum.

Announced on October 28, 2026, the move reflects the technology giant’s efforts to adapt its commercial model to changing online search habits, with users increasingly turning to conversational AI tools to research products, compare options and find information.

The expansion comes as Google’s parent company, Alphabet, reports strong overall revenue growth but faces mounting pressure to demonstrate that its investments in artificial intelligence can translate into sustainable advertising income.

AI Search Ads Reach New International Markets

Google is introducing advertisements in AI Mode across 10 additional countries: Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore.

The company also plans to extend the service to further markets, including Brazil, Mexico and the United Kingdom, during the fourth quarter of 2026.

The rollout brings commercial content deeper into Google’s AI-driven search experience, where users can ask complex questions and receive conversational responses rather than relying exclusively on conventional lists of links.

Google is also introducing multi-turn advertising in the United States, allowing advertisements to appear during follow-up exchanges within AI Mode. This approach could give businesses more opportunities to reach consumers as they refine their questions and move closer to purchasing decisions.

The company says advertisements will be clearly identified as sponsored content as it continues testing formats designed to fit the conversational search environment.

Slower Search Advertising Growth Raises the Stakes

The expansion comes against a challenging financial backdrop for Google’s core search business.

Alphabet reported third-quarter revenue of approximately $127.6 billion, representing a 25% increase compared with the same period a year earlier. However, Google Search revenue growth slowed to 12% year over year, down from 17% in the second quarter and 19% in the first quarter of 2026.

The figures highlight a strategic challenge: although people are continuing to use Google Search, the company must ensure that the growing adoption of AI-powered experiences generates sufficient commercial returns.

Google Services, which includes Search and other major consumer products, generated $96.3 billion in revenue during the quarter, an increase of 11% year over year.

The financial results intensified investor concerns about the pace of growth in Google's established advertising business, while the company continues investing heavily in AI infrastructure and products.

Google Reports Rising Engagement With AI Search

Despite the slowdown in advertising growth, Google says its AI features are encouraging users to conduct more extensive searches.

According to CEO Sundar Pichai, the company recorded its fastest year-over-year growth in search queries in five years. Queries submitted through AI Mode are approximately three times longer than conventional searches, reflecting a shift toward more detailed and conversational interactions.

The company also reports increasing use of multimodal search, which allows people to combine text with images, voice and documents when looking for information.

For advertisers, these changes could create new opportunities to connect with consumers whose needs become clearer over several exchanges. For Google, the challenge is to integrate advertising into these interactions without compromising the usefulness of AI-generated answers.

The company has indicated that early results are encouraging. Its internal data show that click-through rates for sponsored product listings in AI Mode are comparable to those of organic product listings, although these findings do not establish how the formats will perform across all markets over time.

A New Phase in Google's Advertising Strategy

The global expansion signals a broader shift in how Google intends to monetize search as generative AI reshapes the way people access information online.

Traditional search advertising has long relied on matching commercial keywords with sponsored links. AI-powered search introduces a different environment, in which users can explore several questions within a single conversation and receive synthesized responses.

This transition creates opportunities for advertisers but also raises questions about how sponsored recommendations will be presented, how users will distinguish commercial content from AI-generated information, and whether businesses will obtain comparable returns from the new formats.

Google's ability to answer these questions could influence the future of its advertising business as competition in artificial intelligence intensifies.

The company is therefore pursuing two objectives simultaneously: expanding the reach of AI-powered search and ensuring that these new experiences become a meaningful contributor to revenue. The international rollout marks an important step in that strategy, even as the long-term financial impact remains to be established.
