TL;DR
Alphabet said AI Mode’s fast-growing queries were monetized at a lower rate, but Google Search revenue still rose 12% in the third quarter. Reddit CEO Steve Huffman said AI Mode does not drive traffic to websites; the scale of any traffic or revenue effect remains unclear.
Google said fast growth in AI Mode queries weighed on Search revenue growth because those queries were generating less revenue than traditional search activity, while Reddit CEO Steve Huffman said the product does not drive traffic to websites. Alphabet did not quantify AI Mode’s revenue effect, and Search revenue still increased 12% in the third quarter.
On Alphabet’s October 28 earnings call, business chief Philipp Schindler was asked why search activity grew at its fastest pace in five years while revenue growth slowed. He named three factors: foreign-exchange movements, changes in retail and media spending, and the lower monetization of rapidly growing AI Mode queries. Schindler gave no dollar estimate for the AI Mode effect and described it as one factor, not the largest one.
Alphabet reported $63.35 billion in Search and other revenue for the third quarter, up 12% from a year earlier. That means the company did not report that AI Mode had reduced Search revenue in absolute terms. The distinction is between revenue growth and monetization: the company said AI Mode queries were producing less revenue than other search activity, while overall Search revenue continued to rise.
Reddit CEO Steve Huffman offered a separate assessment of the traffic consequences, saying AI Mode did not send traffic to Reddit or, as far as he knew, to other sites. His statement is a company executive’s view, not a quantified industry-wide measurement. The source material also cites a 12.6% fall in Alphabet Class A shares on October 29; reports put the market-value loss between $475 billion and about $500 billion. A 15% closing decline is not supported by those cited figures.

AI Answers Change the Click Equation
The business tension is that AI answers may satisfy more searches without sending users onward, while the answers can generate less advertising revenue per query than conventional results. That could affect both Google’s advertising model and the publishers, forums and merchants that rely on search visitors. Alphabet’s disclosure establishes a monetization difference for AI Mode, but it does not establish how much revenue was affected or whether the feature reduced traffic across the wider web.
The source material cites two indicators of changing publisher traffic. Chartbeat data reportedly showed Google Search’s share of pageviews across its publisher network falling from about 9% in July 2024 to 5% in July 2026. Pew research reportedly found users clicked a result in 8% of visits when an AI summary appeared, compared with 15% when it did not. Those figures describe different measurements and periods; they do not, by themselves, prove AI features caused the broader change.
For businesses, the potential impact differs by model. Publishers and discussion sites may depend on referral visits, while retailers could face a shift toward purchases completed within AI experiences rather than visits to their own sites. The source says Google’s checkout standard covers hundreds of thousands of brands, but provides no measure of how many sales use it. The financial and traffic effects remain hard to compare without consistent reporting.

What Alphabet Disclosed on the Call
Schindler’s remarks came in response to a question from JPMorgan analyst Doug Anmuth about the gap between strong query growth and slower Search revenue growth. Schindler said foreign exchange was the single largest driver of the deceleration relative to the previous quarter. He also cited spending changes among some Asia-Pacific retailers and a normalization in media spending after the football World Cup before mentioning AI Mode’s lower monetization.
Alphabet’s October 29 quarterly filing did not mention AI Mode, according to the source material. It attributed search growth to increased queries, advertiser spending and improvements in ad formats and delivery. In July, Google said its AI features sent billions of clicks to websites each week; the October call, as described in the source, did not provide an updated click figure. The company’s wider response includes placing more ads within AI answers, though the source gives no revenue result for that approach.
The stock decline followed Alphabet’s results and concerns about spending as well as search monetization. The source reports negative free cash flow of $9.1 billion, against analysts’ expected negative $2.7 billion, and quarterly spending of $51.4 billion on data centers and chips. These are reported figures and market context; they do not show that AI Mode alone caused the share-price fall.
“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 October 28 earnings call
The Missing Revenue and Click Figures
Alphabet has not disclosed how many dollars of revenue were affected by lower AI Mode monetization, how that compares with conventional search, or how much the factor changed the quarter’s growth rate. Schindler named exchange rates as the largest driver of Search deceleration relative to the prior quarter, but did not assign amounts to the other factors.
The available information also does not provide a current, directly comparable measure of AI Mode referrals to publishers or Reddit. Huffman’s statement reflects his assessment, while Google’s July claim about billions of weekly clicks concerned its AI features broadly and was not repeated with a new figure in the October call. The cited Chartbeat and Pew findings track different populations and outcomes, so they cannot settle the product-specific question.
It is also unclear how many users complete transactions through Google’s AI checkout, what share of searches will move into AI Mode, and whether ads within AI answers will offset lower monetization per query. The share-price decline occurred amid several reported financial concerns, including cash flow and infrastructure spending; the sources do not isolate the role of AI Mode in the market reaction.
Google’s Next Traffic and Ad Data
The next useful evidence would be a product-specific account from Google of AI Mode revenue per query, advertising performance and referrals to external sites, measured over a defined period. Alphabet has not announced in the supplied material when it will publish such figures. Investors and publishers will also be watching whether ads inside AI answers can generate revenue without further reducing visits to sites.
Policy questions are developing alongside the commercial ones. The source says the UK is requiring an AI opt-out, the European Union is investigating, and five French publisher groups filed a complaint on October 29. It also reports that Google pays more than 400 publications through a licensing pilot. The scope and outcomes of those processes are not specified here, so their eventual effect on AI search or publisher compensation remains unknown.
For now, the confirmed picture is narrower than some circulating headlines: AI Mode queries were less monetized, Search revenue still grew, and Reddit’s CEO says the feature does not send it traffic. More comparable data will be needed to determine the size of the effect on Google and the websites that depend on referrals.
Key Questions
Did Google say AI Mode reduced Search revenue?
No. Google said rapid AI Mode growth affected revenue growth because those queries were less monetized. 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 how much AI Mode changed Search growth. Schindler listed it as one of three factors, with foreign exchange the largest driver of deceleration relative to the previous quarter.
What did Reddit’s CEO say about AI Mode traffic?
Steve Huffman said AI Mode did not drive traffic to Reddit and, as far as he knew, did not drive traffic to other sites. That is his assessment; the source provides no independent, product-wide traffic measurement.
Did Alphabet shares fall 15%?
The cited reports put the October 29 fall in Alphabet Class A shares at 12.6%, not 15%. Estimates of the resulting market-value loss range from $475 billion to about $500 billion.
What information is still missing?
Google has not provided a quantified AI Mode revenue impact or a current, product-specific figure for clicks sent to websites. The effects of ads and checkout within AI experiences are also not quantified in the supplied material.
