TL;DR
Alphabet said fast growth in Google AI Mode queries weighed on Search monetization, but Search revenue still rose 12% in the third quarter. Reddit CEO Steve Huffman said AI Mode does not drive traffic to Reddit or, as far as he knew, other sites; independent data also points to fewer clicks when AI summaries appear. Google has not disclosed how much traffic or revenue AI answers divert from publishers.
Alphabet said Google AI Mode’s fast-growing queries were less monetizable than other Search activity, while Reddit CEO Steve Huffman said the feature was not driving traffic to websites, sharpening questions about how AI answers affect publishers. Alphabet did not quantify AI Mode’s revenue effect, and its Search revenue still grew 12% to $63.35 billion in the third quarter.
On Alphabet’s October 28 earnings call, Chief Business Officer Philipp Schindler cited three factors behind a slowdown in Search revenue growth: foreign exchange movements, reduced spending by some retailers and media advertisers, and lower monetization from fast-growing AI Mode queries. Schindler described the AI Mode effect as one factor, but gave no dollar estimate and did not say it had reduced Search revenue overall.
The comments came after analyst Doug Anmuth asked why search queries were growing at their fastest pace in five years while revenue growth had slowed. Schindler said exchange rates were the largest contributor to the deceleration compared with the prior quarter. He also referred to changes affecting some Asia-Pacific retailers and media spending normalizing after the football World Cup.
Reddit CEO Steve Huffman offered a separate assessment of referral traffic. “The reality is, the AI mode does not drive traffic, not for us and not to anybody, as far as I know,” he said, according to the source report. That is Huffman’s characterization, not a published measurement of traffic across all sites. Alphabet said in July that its AI features sent billions of clicks to websites each week, but the October earnings call supplied no updated click figure.

AI Answers Put Referral Traffic at Issue
The disagreement points to a practical question for newsrooms, forums and other websites: Do AI-generated answers satisfy users without a visit to the sources, or do they still send meaningful referral traffic? Fewer visits can affect advertising income, subscriptions and the ability to reach new readers, even when a search platform continues to attract more queries.
Available figures suggest the issue merits attention but do not settle what caused the changes. Chartbeat data cited in the source report show Google Search’s share of pageviews across its publisher network falling from about 9% in July 2024 to 5% in July 2026. Pew Research found that users clicked a search result in 8% of visits when an AI summary appeared, compared with 15% when it did not. Those observations are not a direct measure of AI Mode’s effect alone, and they do not establish that AI summaries caused the entire difference.
For Google, the business question is also about how to earn from longer, more conversational searches. Schindler said AI Mode queries were three times longer, and Google is testing ads within AI answers. For publishers, the central measure is not only how many questions users ask, but whether those interactions lead to visits and whether the search experience provides visibility or compensation for source material.

What Alphabet and Publishers Reported
Alphabet’s third-quarter figures complicate claims that AI Mode has already cut Search revenue. Search and other revenue rose 12% to $63.35 billion, according to the company. The earnings-call statement describes lower monetization in AI Mode relative to other search activity; it does not identify an overall decline in Search revenue or isolate AI Mode’s contribution to the growth rate.
Alphabet’s quarterly filing, dated October 29, did not mention AI Mode, according to the source report. It attributed Search growth to increased queries, advertiser spending and improvements in ad formats and delivery. The report also says Google has been expanding its commerce plans: its checkout standard covers hundreds of thousands of brands. That could allow some purchases to happen without users visiting a retailer’s website, though the source provides no measure of resulting sales or lost visits.
Regulators and publishers are also pressing for rules around AI search. The source report says 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 October 29. Google also pays more than 400 publications through a licensing pilot, but the report does not give the terms or the program’s reach across the broader publishing industry.
“The strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode.”
— Philipp Schindler, Alphabet chief business officer, on the October 28 earnings call
The Missing Click and Revenue Data
Alphabet has not disclosed how much less revenue AI Mode earns per query, how much the feature contributed to the quarter’s Search growth deceleration, or how many visits AI Mode sends to outside sites. The July figure covering billions of clicks from Google’s AI features was not updated on the October call, and it does not distinguish AI Mode from other features.
The publisher and Pew statistics cited in the source report measure broader search patterns, not a controlled comparison that isolates AI Mode. Their time periods and populations differ, so they cannot by themselves prove that Google’s AI products caused a specific amount of lost traffic. Huffman’s comment is also explicitly qualified by “as far as I know.” The scale of any resulting revenue loss to publishers, forums or retailers remains unestablished.
Alphabet shares fell 12.6% on October 29, their worst daily performance since 2004, according to the source report. But the report also cites concerns about free cash flow and spending on data centers and chips. The market decline cannot be attributed to AI Mode alone, and estimates of the lost market value vary by outlet.
Google’s Next Traffic Disclosures
The next useful evidence would be an updated, clearly defined measure of clicks from AI Mode to external websites, alongside revenue or ad-performance figures that separate AI Mode from other Search products. Google could also clarify how its new ad formats affect monetization and whether longer queries offset lower revenue per query.
Publishers and researchers will need comparable measurements over time to distinguish changes in search traffic from other causes, including shifts in audience behavior and referral sources. Regulatory action in the UK and EU, along with the French publishers’ complaint, may bring further disclosure or changes to how Google offers AI search and access to publisher content. No outcome or timetable is established in the source material.
Key Questions
Did Google say AI Mode reduced Search revenue?
No. Alphabet said AI Mode’s fast-growing queries had lower monetization, which affected Search growth. Search and other revenue nevertheless rose 12% to $63.35 billion in the third quarter.
How much revenue does Google lose from AI Mode?
Alphabet has not provided a dollar figure. The earnings-call comments identify lower monetization as one factor in slower growth, with no estimate of its size.
Does AI Mode send traffic to publishers?
That remains unclear. Reddit CEO Steve Huffman said he did not believe AI Mode drove traffic to Reddit or other sites, while Google previously said its AI features sent billions of clicks to websites each week. The October call included no updated figure specific to AI Mode.
What did the publisher and Pew figures measure?
The source report says Chartbeat tracked Google Search’s share of pageviews across its publisher network, while Pew measured clicks on search results with and without an AI summary. Neither figure isolates AI Mode’s causal effect on traffic.
What developments could clarify the issue?
More detailed Google data on AI Mode referrals and monetization, further independent traffic research, and regulatory proceedings in the UK and EU could add evidence. The timing and results of those developments are not yet clear.
