TL;DR
Alphabet said on Oct. 28 that growth in Google AI Mode queries weighed on Search monetization, but did not quantify the effect; Search revenue still increased 12% in the third quarter. Evidence cited by publishers suggests AI summaries can reduce clicks to websites, while the full traffic and revenue effects for publishers, forums and retailers remain unsettled.
Alphabet told investors on Oct. 28 that rapid growth in Google’s AI Mode queries had weighed on monetization, while reporting that third-quarter Search revenue still rose 12% to $63.35 billion. The company gave no dollar estimate for the effect, leaving publishers, advertisers and investors without a clear measure of how conversational answers may change who receives traffic and search revenue.
Alphabet business chief Philipp Schindler made the comment during an earnings call in response to a question about search-query growth and slower revenue growth. He listed exchange rates as the largest factor in Search’s deceleration compared with the previous quarter, followed by changes in retail and media advertising. He then said strong growth in AI Mode queries had an impact because of lower monetization in AI Mode. He added that the company felt good about its trajectory, but did not state the size of the monetization gap or how much revenue it represented.
The distinction matters: Google described a drag on revenue growth, not a decline in Search revenue. Its reported Search and other revenue reached $63.35 billion, up 12% year over year. Alphabet’s quarterly filing, submitted Oct. 29, did not name AI Mode as a specific revenue factor; it attributed search growth to factors including query volume, advertiser spending and improvements to ad formats and delivery.
Alphabet shares fell 12.6% on Oct. 29, according to reports cited in the source material, making it the company’s steepest daily decline since 2004. Reports put the loss in market value at roughly $475 billion to $500 billion. Those figures describe the market reaction, not a measured cost from AI Mode: Alphabet also reported free cash flow of minus $9.1 billion and quarterly capital spending of $51.4 billion, factors that also concerned investors.

Who Gets the Click—and the Sale
Search engines have traditionally directed users to websites, where publishers, forums and businesses can earn advertising revenue, subscriptions or sales. An AI answer can give a user information directly on the search page. If that answer satisfies the query, the user may not visit the source site. That could shift value from the destination to the platform even when the platform continues to attract more searches.
Some evidence points to a possible traffic effect, though it does not establish the full impact of AI Mode. The source material reports that Chartbeat’s publisher network saw Google Search’s share of pageviews fall from about 9% in July 2024 to about 5% in July 2026. Pew research cited in the source found users clicked a result in 8% of visits when an AI summary appeared, compared with 15% when it did not. These figures concern different measures and do not, by themselves, show how much traffic AI Mode caused publishers to lose.
Retailers face another possible change: a transaction may occur without a shopper visiting a retailer’s website. The source says Google’s checkout standard covers hundreds of thousands of brands. If more discovery and purchasing happen within AI tools, companies may need to reconsider how they reach customers and measure conversions. The scale of any such shift is not yet established.

What the Earnings Call Established
The event behind the debate was Alphabet’s third-quarter earnings call on Oct. 28. Analyst Doug Anmuth asked why queries were growing at their fastest pace in five years while Search revenue growth had slowed. Schindler cited three contributors: foreign-exchange movements, changes in some retail and media spending, and lower monetization of fast-growing AI Mode queries. The source says Google described AI Mode queries as three times longer than traditional searches, but did not provide a revenue-per-query comparison.
In July, Google said its AI features sent billions of clicks to websites every week, according to the supplied material. It did not offer a comparable click figure during the October call. That leaves a gap between the company’s account of overall traffic and the specific question of whether AI answers change the volume or value of visits reaching individual sites.
The policy setting is also changing. The source reports that the United Kingdom requires an AI opt-out offer, the European Union is investigating, and five French publisher groups filed a complaint on Oct. 29. Google also pays more than 400 publications through a licensing pilot, according to the material. These developments reflect disputes over access, compensation and control; they do not resolve how much traffic or revenue AI answers will redirect.
“The strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode.”
— Philipp Schindler, Alphabet business chief, on the Oct. 28 earnings call
The Missing Traffic and Revenue Measures
The most important missing figures are how much revenue Google earns per AI Mode query compared with a conventional search, and how many clicks AI Mode sends to outside websites. Alphabet did not quantify either measure on the Oct. 28 call. The company’s July statement about billions of clicks from its AI features did not provide an October comparison or isolate AI Mode.
The available publisher and Pew figures suggest changes in referral traffic and click behavior, but they do not establish that AI answers alone caused the changes. The studies cited cover particular samples and periods, and the source material does not provide enough methodology to compare their results directly. It is also unclear how much publishers may offset lost visits through licensing payments or other revenue.
Nor does the stock decline prove that investors attributed the fall to AI Mode. Alphabet reported other financial pressures, including negative free cash flow and large investment spending. The company’s overall Search revenue growth remained positive, so claims that Google said AI Mode had caused Search revenue to shrink go beyond the evidence provided.
Metrics That Could Clarify the Shift
The next useful evidence would be more detailed reporting from Alphabet on AI Mode monetization, ad performance and referrals, alongside comparable figures for conventional Search. Without those measures, investors and website operators will have to distinguish broad query growth from the separate questions of revenue per query and traffic sent to publishers.
Publishers, retailers and regulators will also be watching how Google’s AI features develop and how licensing and opt-out rules are applied. The UK, EU and French developments cited in the source may add pressure for clearer terms around the use of publisher material and access to search traffic. No outcome or timetable for those matters is specified in the source material.
For now, the confirmed development is narrower: Google says AI Mode is growing quickly and earns less per query than it would like, while Search revenue continues to rise. Whether that pattern produces a lasting transfer of traffic or advertising value away from websites remains an open question.
Key Questions
Did Google say AI Mode caused Search revenue to fall?
No. Alphabet said lower monetization of fast-growing AI Mode queries weighed on Search growth. Search and other revenue still rose 12% to $63.35 billion in the third quarter.
How much revenue did AI Mode cost Google?
Alphabet did not give a dollar figure or quantify the difference in revenue per AI Mode query. The company identified lower monetization as one of several factors affecting Search growth.
Is there evidence AI summaries reduce website clicks?
The supplied material cites Pew research finding clicks on results in 8% of visits with an AI summary, compared with 15% without one. That result does not by itself establish the effect of AI Mode across all searches or explain changes in publisher traffic.
Why did Alphabet shares fall on Oct. 29?
Shares fell 12.6%, according to the cited reporting. AI monetization was one concern, but Alphabet also reported free cash flow of minus $9.1 billion and capital spending of $51.4 billion; the source does not establish a single cause for the decline.
