Google Search Advertising Revenue Climbs 12% Despite Growing Questions About AI’s Impact

52

Google generated $63.3 billion in Search and related advertising revenue during the third quarter of 2026, an increase of 12% year on year, as its core advertising business continued expanding. This growth comes despite concerns over how artificial intelligence could change search behaviour.

Retail advertising contributed the most to Search growth, followed by financial services, according to Alphabet’s earnings discussion.YouTube advertising revenue also increased, rising 9% to $11.2 billion, while total Google advertising revenue grew 11%. 

The results arrive as Google introduces more AI-powered experiences into its search products. AI-generated summaries and conversational interfaces increasingly allow users to find information without following the same sequence of links that characterised traditional search.

The changes have raised questions about website traffic, advertising placements and the economics of attracting customers through search. However, Google’s latest financial results indicate that these changes have not yet prevented its advertising business from growing.

That said, revenue growth does not establish that individual advertisers are achieving better results, as campaign economics depend on factors such as keyword competition, click prices, conversion rates and the quality of customer traffic.

Google is also expanding advertising within AI Mode, bringing commercial placements into conversational search experiences across additional countries. This creates opportunities for the company to monetise new user behaviour while maintaining the established search business that provides much of its advertising revenue.

The transition is likely to involve experimentation with placement formats, campaign measurement and how consumers interact with sponsored content.

Google’s third-quarter performance demonstrates the financial strength of its current model. The next test will be whether its new search experiences can sustain advertiser demand and deliver measurable business outcomes as more users rely on AI-generated responses.
