In the third quarter of 2026, Google Search revenue growth slowed to 12% compared to 17% in the previous quarter. Paid ad clicks increased by only 8%, while in the second quarter this figure stood at 13%. At the same time, total search query volumes are showing record growth rates over the past five years — users are turning to the search engine more actively, but the conversion of these queries into ad revenue is falling. ### AI Search Grows, But Fails to Bring Money A key factor in the slowdown has been the shift of users toward artificial intelligence search forms. Google is embedding AI-generated summaries in AI Overviews directly into search results, while the AI Mode allows users to converse with the search engine in a chat format. However, as company Chief Operating Officer Philipp Schindler acknowledged, queries in AI Mode are showing high growth rates but generate significantly less advertising revenue than traditional search queries. Users get an answer from the neural network and, without switching to third-party sites, fulfill their information need — and historically, these transitions and ad clicks generated the bulk of the search engine's income. ### Advertisers Report Stagnation in Efficiency Third parties confirm the picture painted by Google itself. According to the advertising agency Tinuiti, its clients' spending on Google ads in the third quarter of 2026 grew by 14% year-over-year, yet investment efficiency — the ratio of costs to conversions obtained — remained at the same level. Google does not yet provide a separate tool for evaluating ad placement results specifically in AI search, preventing advertisers from accurately measuring the return on the new model. Furthermore, a study of referrals from ChatGPT to online retail sites showed that such visits bring retailers less revenue than referrals from traditional Google search. ### Google's Strategy: Advertising Inside AI Answers The company hopes to change the situation by placing ads directly within AI-generated answers. Google is already experimenting with ads in AI Overviews and AI Mode, expanding the availability of this format to international markets. The company claims that neural network search creates additional advertising opportunities: users ask follow-up questions and explore products and services that might have remained outside their queries in traditional search. Nevertheless, none of these mechanisms has yet shown advertising returns comparable to classical search. ### 200 Billion Dollars on AI and Investor Pressure The situation is becoming particularly acute against the backdrop of Alphabet's massive capital expenditures. In 2026, the company plans to direct about $200 billion toward AI infrastructure development. Investors will have to assess how quickly these investments will begin to pay off, especially if the new search model proves systematically less profitable than the traditional one. Following the publication of its quarterly report, Alphabet shares lost about 14% of their value — the market reacted to the signal that AI search monetization is lagging behind expectations. ### Second Transformation: More Complex Than the Mobile Transition Google has already gone through a massive business model overhaul during the transition from desktop search to mobile. However, the current transformation may prove more complex: if users increasingly receive complete answers directly from the neural network, the company will have to rebuild the monetization model for its core business from scratch. The task facing Google is to learn how to make money on AI search without lagging behind the traditional search engine in advertising efficiency — and to do so before the outflow of advertising budgets becomes irreversible. ## Fact-Check & Sources - [Google ещё не придумала, как зарабатывать на ИИ-поиске столько же, сколько на обычном window-new](https://3dnews.ru/1150854/google-eshchyo-ne-pridumala-kak-zarabativat-na-iipoiske-stolko-ge-skolko-na-obichnom) - Single source.
