Google's revenue from advertising expands alongside its development of AI search technology - Artificial Intelligence (AI) is propelling Google's advertising sector, enhancing search capabilities.

Google is revolutionising its search engine by incorporating more AI-generated summaries to answer user queries, a move that is reshaping its advertising business. Despite a decline in Google's stock price by approximately 1.5% in after-hours trading, the tech giant's total revenue for the quarter grew by a robust 14% to $96.43 billion, surpassing market expectations.

The AI Overview (SGE) presents answers directly on the search results page, reducing the traditional ad visibility at the top of the page and decreasing click-through rates (CTRs) for ads. However, Google is compensating by integrating ads within the AI overview itself, labelled as "Sponsored" content, opening new ad formats such as shopping carousels and shoppable images within AI-driven search experiences.

This evolution means that while ads are no longer always in prime top-of-page positions, Google is creating new monetization opportunities by blending ads more closely with AI-generated content. However, the result for advertisers has been lower clicks and conversions and rising costs per click (CPC) due to heightened competition for high-visibility slots. Advertisers are adapting by refining ad creative and bidding strategies to maintain performance.

From a revenue perspective, Google's search and other revenues grew 12% year-over-year to $54.2 billion in Q2 2025, with strong contributions especially from retail and financial services advertisers. Yet, Google's Network advertising revenue declined slightly by 1% due to reduced publisher traffic as AI Overviews satisfy user queries on the results page itself, lowering traditional website visits.

Google CEO Sundar Pichai emphasised that AI positively impacts all parts of the business. The company is balancing AI-powered user experience improvements with evolving advertising monetization strategies, aiming to maintain and grow revenues while adapting to shifting user search behaviour and expectations.

It's important to note that the decline in Google's stock price is not directly related to the growth or performance of the advertising business. This decline occurred following the announcement of Google's financial results, and it's not related to any potential impact on revenue from advertising due to the reduction in the incentive to click on links next to search results or any changes in the AI-generated summaries being incorporated into the search engine.

In summary, AI integration has introduced a paradigm shift that reduces traditional ad prominence and click-through for many queries, creates new ad formats integrated within AI search results, raises CPCs due to competition for remaining ad real estate, sustains overall search advertising revenue growth but challenges traditional traffic-driven publisher revenue, and necessitates advertiser strategy adjustments around targeting, creative, and bidding. Google continues to navigate this new landscape, striving to deliver a superior user experience while maximising advertising revenue.

1. The increase in Google's revenue is partly attributed to the growth in financial services advertising, as the AI Overview (SGE) presents answers directly on the search results page, potentially driving more financial inquiries and thereby increasing ad spending in this sector.
2. In response to the integration of ads within the AI overview, advertisers are experimenting with artificial-intelligence-powered strategies in their ad creative and bidding, aiming to create more compelling and relevant content that stands out among the AI-driven search experiences, thereby increasing community aid and financial aid for successful ad placement.
