TL;DR

Alphabet said fast growth in Google AI Mode queries weighed on search monetization, but did not quantify the effect; Search & other revenue still rose 12% in the third quarter. Publisher traffic data and a Pew study suggest AI answers can reduce clicks, while the scale of the impact across the open web remains uncertain.

Alphabet said Google AI Mode queries are growing quickly but earning less than other search activity, a disclosure that puts pressure on the longstanding exchange between search engines and websites: Google answers questions, and websites receive visits. The company did not estimate the revenue effect, and its Search & other revenue rose 12% to $63.35 billion in the third quarter.

On Alphabet’s Oct. 28 earnings call, business chief Philipp Schindler cited lower monetization of fast-growing AI Mode queries as one reason search revenue growth slowed. He named two other factors: foreign-exchange movements, which he said were the largest driver of the slowdown relative to the prior quarter, and changes in retail and media spending. He gave no dollar estimate for AI Mode’s effect.

The disclosure does not mean Google Search revenue fell. Alphabet reported $63.35 billion in Search & other revenue, up 12% year over year. The company’s Oct. 29 quarterly filing did not separately discuss AI Mode; it attributed search growth to factors including query volume, advertiser spending, and improvements to ad formats and delivery.

The market reaction was substantial, but the figures need precision. Alphabet Class A shares fell 12.6% on Oct. 29, according to Fortune, their steepest one-day decline since 2004. Reports put the market-value loss between roughly $475 billion and $500 billion; the source material found no close-of-day basis for a 15% share-price drop. Alphabet also reported free cash flow of minus $9.1 billion, while quarterly capital spending reached $51.4 billion, adding to investor concerns.

The Cost of Fewer Website Visits

AI answers may change the value of a search query for both Google and the sites whose material helps answer it. If users get enough information on a results page, they may not click through. That can reduce opportunities for publishers, forums, and retailers to earn advertising or sales revenue, even while Google continues to attract search activity.

Available measures point to a possible traffic effect, but they do not settle its scale across the web. Chartbeat data cited in the source show Google Search’s share of pageviews across its publisher network declining from about 9% in July 2024 to 5% in July 2026. Pew Research Center found that users clicked a result in 8% of visits when an AI summary appeared, compared with 15% when it did not. These are different measures and populations; neither alone proves that AI answers caused every change in publisher traffic.

For businesses, the issue is not limited to clicks. Google says it is adding advertising to AI experiences, while its checkout standard covers hundreds of thousands of brands, according to the source. If transactions increasingly happen within search interfaces, some merchants could make sales without receiving a website visit. The terms, revenue flows, and effects on different types of businesses remain unsettled.

From Search Links to AI Answers

Google has long sent users from search results to external websites, which can then generate revenue through advertising, subscriptions, or commerce. AI Mode changes the format by responding in a conversational interface and can draw on information that users might otherwise seek across multiple pages. Google says AI Mode queries are three times longer than traditional searches and that overall query growth is at its highest pace in five years. Those statements describe activity, not how many users click through to source sites.

Google said in July that its AI features send “billions of clicks to websites every week.” The source material notes that the company did not provide a comparable click figure on the October earnings call. Meanwhile, Reddit chief executive Steve Huffman said AI Mode does not drive traffic to Reddit or, as far as he knew, to other sites. That is an executive’s account, not a comprehensive independent measurement.

Policy disputes are also developing. The UK is requiring Google to offer an AI opt-out, the European Union is investigating, and five French publisher groups filed a complaint on Oct. 29, according to the source. Google also pays more than 400 publications through a licensing pilot. These measures reflect competing attempts to address how AI search uses and distributes publishers’ material.

“The strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode.”

— Philipp Schindler, Google business chief, on Alphabet’s Oct. 28 earnings call

Traffic and Revenue Still Unmeasured

Alphabet has not disclosed how much less revenue an AI Mode query generates, how many searches now use the feature, or how many clicks AI answers send to websites. The company’s quarterly filing does not break out AI Mode. Without comparable figures over time, it is difficult to determine how much the feature contributed to the change in search growth or to changes in publisher traffic.

The cited traffic studies cover particular publisher networks and research methods, not every website or search user. Other factors—including changes in audience behavior, search rankings, and publisher platforms—may also affect visits. It is also unclear how Google’s plans to place ads in AI answers, its licensing arrangements, and its checkout tools will distribute revenue among Google, publishers, and merchants.

Policy Tests and Ad Changes Ahead

The next signals to watch are Google’s future disclosures on AI Mode usage, ad monetization, and referrals to external sites. Comparable figures in later earnings reports would help show whether the gap between query growth and search revenue growth is changing, though Alphabet has not announced a timetable for a dedicated breakdown.

Regulatory and publisher disputes will continue to shape the terms around AI search. The UK opt-out requirement, the EU investigation, and the French publishers’ complaint could prompt changes to access, licensing, or product design. For now, the confirmed picture is narrower: AI Mode queries are less monetized, Google Search revenue is still growing, and the size of any resulting loss of traffic or income for websites remains unknown.

Key Questions

Did Google say AI Mode reduced Search revenue?

Google said fast growth in AI Mode queries affected monetization because those queries were earning less. Alphabet did not report a fall in total Search & other revenue, which rose 12% to $63.35 billion in the third quarter.

How much revenue does Google lose on AI Mode queries?

Alphabet has not given a dollar figure or a percentage for the monetization gap. Schindler described the effect but did not quantify it.

Are AI answers reducing website clicks?

Some evidence suggests fewer clicks in certain settings. Pew found clicks on results in 8% of visits when an AI summary appeared, compared with 15% when it did not. That study does not establish the impact on all websites or prove that AI summaries explain broader traffic trends.

Why did Alphabet shares fall on Oct. 29?

Alphabet Class A shares dropped 12.6%, while investors also faced concerns about free cash flow and spending on data centers and chips. The source material does not attribute the entire decline to AI Mode.

The UK is requiring an AI opt-out, the EU is investigating, and five French publisher groups filed a complaint on Oct. 29. The outcomes and any resulting changes to Google’s products or publisher arrangements remain pending.
