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. Publishers and Reddit have raised concerns about referral traffic, while Google says its search features send billions of clicks to websites each week. The size of AI Mode’s effect on traffic and revenue has not been disclosed.
Google parent Alphabet said on October 28 that the rapid growth of AI Mode queries had weighed on search monetization because those queries generated less revenue than other searches. The disclosure has sharpened concerns among publishers, forums and retailers about whether AI-generated answers will reduce visits to their websites, though Alphabet did not quantify the revenue effect or provide a current measure of AI Mode referrals.
Chief business officer Philipp Schindler made the comment during Alphabet’s third-quarter earnings call, after an analyst asked why search queries were growing at their fastest pace in five years while search revenue growth had slowed. Schindler named exchange rates as the largest factor in the slowdown relative to the prior quarter, followed by conditions affecting some retailers and media spending. He then said AI Mode’s strong query growth had an impact because of its lower monetization.
That statement did not mean Google Search revenue declined. Alphabet reported that Search and other revenue rose 12% to $63.35 billion in the third quarter. Schindler gave no estimate of how much less revenue an AI Mode query generated, and he did not say AI Mode was the largest cause of the change in search growth. Alphabet’s quarterly filing, submitted October 29, did not mention AI Mode; it attributed search growth to more queries, advertiser spending and improvements to ad formats and delivery.
The disclosure came amid a sharp drop in Alphabet shares. Class A shares fell 12.6% on October 29, their worst one-day performance since the company went public in 2004, according to reports cited in the source material. Estimates of the resulting market-value decline varied, from roughly $475 billion to about $500 billion. A reported 15% closing decline was not supported by those figures. Investors were also reacting to Alphabet’s negative $9.1 billion in free cash flow and quarterly capital spending of $51.4 billion, not solely to AI Mode.

The Cost of Answers Without Clicks
The concern for websites is that an AI answer can satisfy a searcher without a visit to the source. If that behavior becomes common, publishers may lose page views and the advertising or subscription opportunities attached to them, even as people continue using Google. Reddit chief executive Steve Huffman said AI Mode does not drive traffic to Reddit or, as far as he knew, to other sites. That is his assessment; the source material provides no independent traffic data specific to AI Mode.
Other figures point to a broader shift in search referrals, but do not establish that AI Mode alone caused it. Chartbeat data cited in the source material show Google Search’s share of page views across its publisher network falling from about 9% in July 2024 to 5% in July 2026. Pew Research measured clicks on traditional results in 8% of visits when an AI summary appeared, compared with 15% when it did not. Those findings concern AI summaries and search traffic, not a complete accounting of AI Mode’s effect across the web.
Retailers may face a different change: a customer could complete a purchase through an AI-assisted experience without first visiting a store’s website. Google’s checkout standard, according to the source, covers hundreds of thousands of brands. That could alter how businesses reach customers and measure sales, but the source does not provide data showing how many purchases currently happen this way or how much traffic retailers lose as a result.

What Alphabet’s Figures Establish
The dispute turns partly on the difference between search growth and search referrals. More queries can lift search use while producing less revenue per query, as Schindler’s comments indicate. But Alphabet has not released a dollar estimate for AI Mode’s lower monetization, nor did the earnings call provide a count of clicks AI Mode sends to outside sites.
Google said in July that its AI features send billions of clicks to websites each week. The source material says the company did not repeat a comparable figure on the October earnings call. Without a consistent measure, that earlier statement cannot show whether referrals have risen or fallen since then, or isolate traffic from AI Mode specifically.
The policy environment is also changing. The source reports that 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, according to the source. These developments show that access, attribution and compensation are under scrutiny, but they do not settle whether AI answers are reducing web traffic overall.
“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 Traffic and Revenue Measures
Several key measurements remain unavailable. Alphabet has not said how much less revenue an AI Mode query generates, how many AI Mode sessions lead to an outside click, or how those rates compare with conventional search. The available publisher and Pew figures cover broader search patterns or AI summaries and cannot establish the effect of AI Mode on their own.
It is also unclear how users’ behavior will change as Google adds advertising and shopping features to AI answers. The source describes Google’s plans and existing checkout standard, but provides no detailed results for conversions, referrals or publisher compensation tied specifically to AI Mode. Reddit’s statement reflects the company’s view, not a measured estimate for the entire web.
More Data Will Shape the Debate
The next useful evidence would be comparable reporting from Google on AI Mode referrals and monetization, alongside independent measurements that distinguish AI Mode from other search features. Publishers and retailers will also need to track visits and sales across those channels rather than treating broad changes in search traffic as proof of a single cause.
Regulatory scrutiny and the French publishers’ complaint may bring further attention to how AI answers use and link to outside material. For now, the confirmed development is narrower: AI Mode queries are growing quickly and, according to Alphabet, are less monetizable. Whether that shift materially reduces the wider web’s traffic or revenue remains unresolved.
Key Questions
Did Google say AI Mode reduced Search revenue?
Alphabet said AI Mode’s fast query growth had an impact because those queries had lower monetization. Search and other revenue still rose 12% to $63.35 billion in the third quarter, and the company did not quantify AI Mode’s revenue effect.
Did Alphabet shares fall 15%?
The source material reports a 12.6% fall in Class A shares on October 29. It does not support a 15% decline at the close. Estimates of the company’s lost market value differed among reports.
Is AI Mode reducing traffic to websites?
Some publishers and Reddit’s chief executive have raised concerns, and broader research cited in the source shows changes in search referrals and clicks. Those figures do not isolate AI Mode, so its specific effect on website traffic is not yet established.
What does Google say about clicks from its AI features?
Google said in July that its AI features sent billions of clicks to websites each week. The source material says the company did not provide an updated comparable figure during the October earnings call.
