TL;DR
Alphabet said on its October 28 earnings call that growth in Google AI Mode queries weighed on Search monetization, but it gave no estimate of the revenue effect. Search and other revenue still grew 12% in the third quarter. Reddit CEO Steve Huffman said AI Mode does not drive traffic to sites, while available publisher data points to declining Google referral traffic.
Alphabet said on its October 28 earnings call that rapid growth in Google’s AI Mode queries weighed on Search monetization, but the company did not quantify the effect and Search revenue still rose 12% to $63.35 billion in the third quarter. The disclosure came as Reddit CEO Steve Huffman said AI Mode does not drive traffic to websites, sharpening questions about how Google’s answer-style search affects publishers and other sites that depend on referrals.
Google business chief Philipp Schindler named three factors behind slower Search revenue growth compared with the prior quarter: currency movements, changes in retail and media spending, and lower monetization of fast-growing AI Mode queries. He said exchange rates were the largest of those factors relative to the second quarter. Schindler supplied no dollar estimate for AI Mode’s effect and did not say that Search revenue had fallen.
Alphabet shares fell 12.6% on October 29, according to Fortune, their steepest one-day decline since the company went public in 2004. Reports put the loss in market value at roughly $475 billion to $500 billion; the source material does not support a 15% closing decline. Investors were also reacting to Alphabet’s cash position: CNBC reported free cash flow of minus $9.1 billion for the quarter and capital spending of $51.4 billion.
Huffman made his traffic assessment in comments about AI Mode: “The reality is, the AI mode does not drive traffic, not for us and not to anybody, as far as I know.” That is the Reddit chief executive’s view, not a measurement covering every website. The source material also reports that Google said AI Mode queries are three times longer than conventional queries and that query growth overall is at its fastest pace in five years.

The Cost of Answers Without Clicks
The dispute concerns the economics of search as well as its format. Google’s traditional results can send visitors to publishers, retailers and forums; an AI response may answer a question before a user visits any of those sites. If AI queries grow while generating less advertising revenue per query and fewer referrals, Google faces a challenge in monetizing the product while websites may lose visits that support advertising, subscriptions or sales.
Available figures offer signals, not a complete accounting. The source material 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. It also cites a Pew study in which users clicked a result in 8% of visits when an AI summary appeared, compared with 15% when it did not. These findings describe particular samples and measures; they do not establish that AI Mode alone caused the changes.
Retailers may face a related shift: a user could complete a purchase through Google’s AI tools without visiting a merchant’s site. The source material says Google’s checkout standard covers hundreds of thousands of brands. The scale of any resulting change in sales, referral traffic or advertising income has not been quantified.

What Alphabet Told Investors
The exchange took place during Alphabet’s third-quarter earnings call on October 28. JPMorgan analyst Doug Anmuth asked why search queries were growing at their fastest pace in five years while Search revenue growth had slowed. Schindler first pointed to foreign exchange, then to spending patterns among some Asia-Pacific retailers and media advertisers, before citing lower monetization in AI Mode.
Schindler said: “To be clear, we feel very good about our trajectory here.” The remark expressed confidence in Google’s direction; it did not provide a revenue forecast or measure AI Mode’s current contribution. Alphabet’s October 29 quarterly filing, as described in the source material, did not mention AI Mode and attributed Search growth to query volume, advertiser spending, and improvements in ad formats and delivery.
Google had previously said its AI features send “billions of clicks to websites every week,” according to the source material. The October call included no comparable traffic figure. Google is also testing monetization within AI answers, while regulatory and publisher disputes continue: the UK has required an AI opt-out offer, EU authorities are investigating, and five French publisher groups filed a complaint on October 29. Google also pays more than 400 publications through a licensing pilot, according to the source material.
““It’s worth noting that 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 Revenue and Traffic Measures
Alphabet has not disclosed how much revenue AI Mode generates, how its monetization compares with conventional Search, or the amount of revenue growth it may be reducing. Schindler identified AI Mode as one factor among three and said exchange rates were the largest driver of the slowdown relative to the second quarter. The available figures do not isolate AI Mode’s contribution.
It is also unclear how much traffic AI Mode sends to websites across the open web. Google’s earlier figure about billions of weekly clicks covered its AI features generally, while Huffman’s assessment concerned traffic and did not provide a measured sample. Publisher-network and user-click studies point to changes in referrals and behavior, but their scope and methods do not establish a direct causal link to AI Mode. The effects on merchant visits and completed sales are also not yet quantified.
Signals to Watch in Coming Reports
Future Alphabet earnings calls and filings may show whether AI Mode’s share of queries keeps growing and whether Google provides clearer figures on its advertising revenue and referrals. The company’s effort to add ads to AI answers will be an important indicator of whether it can raise monetization without changing the search experience in ways users reject.
Publishers, retailers and investors will also be watching independent traffic measurements and the outcome of the UK, EU and French proceedings described in the source material. For now, the confirmed picture is limited: AI Mode queries are growing quickly and are less monetized than other Search activity, while the size of the revenue effect and the overall change in website traffic remain unsettled.
Key Questions
Did Google say AI Mode reduced Search revenue?
No. Schindler said fast growth in AI Mode queries had an impact because those queries were less monetized. Alphabet’s Search and other revenue still increased 12% to $63.35 billion in the third quarter.
How much revenue does AI Mode generate?
Alphabet did not disclose a figure. Schindler gave no estimate of AI Mode’s revenue or of how much it affected Search revenue growth.
Did Reddit say Google AI Mode sends no traffic?
Reddit CEO Steve Huffman said he did not believe AI Mode drives traffic to Reddit or other sites, “as far as I know.” That is his assessment, not a published measurement of traffic across all websites.
Why did Alphabet shares fall on October 29?
Alphabet’s Class A shares fell 12.6%, their steepest one-day decline since 2004, according to Fortune. The source material also reports investor concerns about free cash flow and high spending on data centers and chips; it does not attribute the drop to AI Mode alone.
Is there evidence that AI search reduces website clicks?
The source material cites a Pew study reporting clicks on results in 8% of visits when an AI summary appeared and 15% when one did not, plus Chartbeat data showing a decline in Google Search’s share of pageviews across its publisher network. Those figures do not establish that AI Mode alone caused the changes.
