TL;DR
Google said fast-growing AI Mode queries generated less revenue per query than traditional search, contributing to a slower pace of Search revenue growth. Alphabet’s Search revenue nevertheless rose 12% to $63.35 billion in the third quarter. Evidence suggests AI summaries can reduce clicks in some settings, but the full traffic and revenue effects remain unclear.
Alphabet said fast growth in Google’s AI Mode, its chat-style search product, weighed on the pace of Search revenue growth because those queries were less well monetized than other searches. But Google did not say AI Mode reduced Search revenue overall: Search and other revenue rose 12% to $63.35 billion in the third quarter, according to the figures cited in Alphabet’s earnings materials.
On the October 28 earnings call, Google business chief Philipp Schindler named three factors behind Search revenue deceleration compared with the prior quarter. He said foreign exchange was the largest factor, followed by changes in some retail and media spending, then the lower monetization of rapidly growing AI Mode queries. Schindler gave no dollar estimate for AI Mode’s effect and did not quantify the revenue difference between an AI Mode query and a conventional search.
The distinction matters: a slower growth rate is not the same as falling revenue. Alphabet’s Search and other revenue increased 12% year over year in the third quarter. The source’s review of the company’s October 29 filing also found no specific AI Mode discussion in the 10-Q; it described Search growth in terms of query volume, advertiser spending and changes to ad formats and delivery.
Alphabet shares fell 12.6% on October 29, according to Fortune, a decline CNBC described as the company’s worst trading day since 2004. The loss in market value was reported at different estimates, from about $475 billion to roughly $500 billion. Those market figures do not establish that AI Mode caused the sell-off: reports also pointed to concerns about cash flow and spending. Alphabet reported negative free cash flow of $9.1 billion for the quarter and capital expenditure of $51.4 billion, according to the source material.

The Cost of Answers Without Clicks
AI answers can change the economics of search if users get what they need directly on Google and visit fewer outside sites. For publishers that depend on search referrals, fewer visits can mean fewer opportunities to earn advertising or subscription revenue. The financial effect depends on more than traffic: a publisher’s audience, page value, ad rates and other sources of visitors also matter.
Available figures point to a possible shift, but they do not settle its scale. The source cites Chartbeat data showing Google Search’s share of pageviews across its publisher network falling from about 9% in July 2024 to 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 one did not. These findings have different populations and measures; neither alone proves that AI answers caused a particular publisher’s revenue loss.
Retailers and other businesses may face another change: purchases could happen through AI-assisted tools without a traditional visit to a retailer’s website. The source says Google’s checkout standard covers hundreds of thousands of brands, but it does not provide transaction or revenue results. For users, AI answers may make information quicker to access; for businesses, the trade-off is whether that convenience still sends customers, attention and revenue to the sites that supply information or sell products.

What Google’s Earnings Call Established
The discussion followed a question from JPMorgan analyst Doug Anmuth about why search activity was growing quickly while Search revenue growth had slowed compared with the second quarter. Schindler said query growth was at its highest level in five years and that AI Mode queries were three times longer. Longer queries may represent more activity, but Google’s comments did not establish that they generate equivalent ad revenue.
Google has previously said its AI features send “billions of clicks to websites every week,” according to the source. The October earnings call did not include a comparable click figure. That leaves a gap between Google’s broad account of referral traffic and the particular question raised by the lower monetization comment: how many visits AI Mode sends, and how those compare with conventional search.
The source also reports that Google is testing more advertising within AI answers and pays more than 400 publications through a licensing pilot. Those arrangements form part of a wider discussion over how publishers are compensated when search products use or summarize their material. The cited figures do not show whether licensing payments offset any lost referral revenue.
“The strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode.”
— Philipp Schindler, Google’s business chief, on Alphabet’s October 28 earnings call
The Missing Click and Revenue Data
Google has not disclosed how many clicks AI Mode sends to outside websites, how that compares with conventional results, or the specific revenue impact of its lower monetization. The third-quarter Search revenue increase shows that the business grew overall, but it does not reveal how much AI Mode affected growth relative to what would otherwise have happened.
The cited traffic studies also have limits. Chartbeat’s publisher-network pageview share and Pew’s observed click rates measure different things, and the figures presented here do not establish a single causal estimate for AI Mode. It remains unclear how results vary by query, industry, publisher or user, and whether additional ads or licensing payments can compensate sites for fewer visits. The source also describes regulatory and industry developments, including a UK opt-out requirement, an EU investigation and a complaint by five French publisher groups filed October 29; their eventual effects are not yet known.
More Data on Referrals and Ads
The next useful evidence would be comparable figures from Google on AI Mode referrals, advertising revenue per query and the share of searches that end without a website visit. Publishers and researchers may also release further traffic data that distinguishes AI summaries from other search features and accounts for changes in audience and search behavior.
For now, the confirmed financial picture is narrower: Google said AI Mode’s lower monetization contributed to slower Search revenue growth, while Search revenue still increased year over year. Investors, publishers, retailers and regulators will be watching how Google adds ads and checkout options to AI experiences, and whether those changes produce measurable referrals or sales for outside businesses. No published results in the source establish that outcome yet.
Key Questions
Did Google say AI Mode reduced Search revenue?
No. Google said AI Mode’s lower monetization weighed on the pace of Search revenue growth. Search and other revenue still rose 12% to $63.35 billion in the third quarter.
How much revenue did AI Mode cost Google?
Google did not provide a dollar figure or quantify the revenue difference between AI Mode and conventional search. The company identified lower monetization as one factor in deceleration, after foreign exchange and changes in retail and media spending.
Do AI answers lead to fewer website clicks?
Some cited research found lower click rates when an AI summary appeared, and Chartbeat data showed Google Search making up a smaller share of pageviews across its publisher network over the stated period. These measures do not by themselves establish the cause or the effect for every site.
Why did Alphabet shares fall on October 29?
Alphabet’s Class A shares fell 12.6%, in a decline reported as its worst since 2004. The source says reporting also cited concerns about free cash flow and investment spending; the share-price move cannot be attributed to AI Mode alone.
