Alphabet said October 28 that the rapid growth of Google’s AI Mode had weighed on search monetization because the queries generated less revenue than other searches. The disclosure highlights a broader concern for publishers and online businesses: AI answers may satisfy users without sending as many visits to the sites that supply information, but Alphabet did not quantify any lost revenue or referral traffic.

Speaking on Alphabet’s third-quarter earnings call, business chief Philipp Schindler named lower monetization from AI Mode as one of three factors behind a slowdown in Search revenue growth. He also cited foreign-exchange effects and changes in retail and media advertising. Schindler did not provide a dollar estimate for AI Mode’s impact, and the company’s quarterly filing did not mention the product by name.

Search revenue nevertheless rose 12% to $63.35 billion in the quarter. Alphabet’s explanation was that AI Mode queries were growing quickly but earning less per query; it did not say that AI Mode caused Search revenue to decline. Google has said query growth is at its highest level in five years and that AI Mode searches are three times longer, though longer queries do not by themselves establish how many users click through to websites.

There are signs of referral pressure outside Alphabet’s revenue figures. 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. A Pew Research Center study 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 measures and do not, on their own, prove that AI summaries caused the longer-term publisher trend.

The Cost of Answers Without Clicks

Search has traditionally connected a user’s question to websites, where publishers, retailers and forums can attract readers, customers or community members. If an AI answer resolves more questions on the search page itself, the user may get information without visiting those sources. That could weaken a major route to audiences, even if the search engine continues to attract queries.

The business effects may differ by sector. Publishers depend on page visits for advertising and subscriptions; forums rely on users arriving to read and contribute; retailers may lose a visit even when a customer ultimately buys. The source report says Google’s checkout standard now covers hundreds of thousands of brands, raising the possibility of purchases completed with less direct website traffic. The available material does not establish how often that happens or how much it changes merchants’ sales.

For Google, the issue is also a revenue-model question. Schindler’s remarks indicate that AI Mode currently earns less per query, while Google is expanding advertising options in AI answers. Whether those formats can generate comparable revenue without reducing user trust or website referrals remains unmeasured in the information provided.

What Alphabet Disclosed on October 28

The comments came after analyst Doug Anmuth asked why search queries were growing at their fastest pace in five years while Search revenue growth had slowed. Schindler said foreign exchange was the largest factor in the slowdown relative to the previous quarter. He then cited pressure on some Asia-Pacific retailers after the European Union ended a customs exemption for low-cost parcels, as well as a normalization in media spending after the football World Cup.

Schindler’s statement on AI Mode was narrower than some headlines suggested: “the strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode.” He added that Google felt good about its trajectory. The company’s Search revenue still increased year over year, so the statement describes pressure on monetization and growth, not a reported revenue contraction caused by AI Mode.

Alphabet shares fell 12.6% on October 29, their steepest one-day decline since 2004, according to the cited reports. Estimates of market value lost differed, ranging from $475 billion to about $500 billion. The source material also reports free cash flow of minus $9.1 billion and quarterly spending on data centers and chips of $51.4 billion. Those figures point to other investor concerns; the share-price move cannot be attributed to AI Mode alone.

Google said in July that its AI features sent “billions of clicks to websites every week,” but the October earnings call included no updated click figure. The source report also notes regulatory and industry developments: a UK requirement for an AI opt-out, an EU investigation, a complaint filed by five French publisher groups on October 29, and a licensing pilot involving more than 400 publications.

“The strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode.”

The Missing Click and Revenue Data

The central gap is a current, comparable measure of how many visits AI Mode sends to websites and how that compares with traditional search. Alphabet did not give an AI Mode revenue figure or a click-through count on the call. Its July statement covered AI features broadly and does not provide an October comparison or a breakdown by product.

The cited publisher and Pew figures offer evidence of changing referral patterns and user behavior, but they have different methods and scopes. The material does not establish that AI summaries alone caused Chartbeat’s two-year change, nor does it show how the results vary by subject, publisher size or type of search. It also remains unclear whether ads and direct checkout options inside AI experiences will compensate businesses for fewer visits.

Metrics to Watch in Coming Reports

Future Alphabet earnings calls and filings may show whether AI Mode’s share of searches, advertising formats or monetization changes. A useful comparison would include both revenue per query and outbound clicks, measured over a stated period and against a clear baseline. The material provided does not identify a date when Google will publish those figures.

Publisher traffic reports, further research into user clicks, and the outcomes of the cited UK, EU and French developments could add detail on how AI answers affect referrals and what choices publishers have. For now, the confirmed point is limited: AI Mode queries are growing and currently monetize less, while the net effect on websites and online businesses remains unsettled.

Key Questions

Did Google say AI Mode reduced Search revenue?

No. Alphabet said AI Mode’s rapid query growth weighed on monetization, but Search revenue rose 12% to $63.35 billion in the third quarter. Schindler did not quantify the AI Mode effect.

Is there proof AI answers reduce website clicks?

The source report cites a Pew study in which clicks occurred in 8% of visits when an AI summary appeared, compared with 15% without one. That finding concerns the study’s measured visits; it does not establish the effect across all searches or explain the full publisher traffic trend.

How much referral traffic does Google’s AI Mode send?

The available information does not provide a current AI Mode click count. Google said in July that its AI features sent billions of weekly clicks to websites, but the October earnings call included no updated figure or product-specific breakdown.

Why did Alphabet shares fall on October 29?

Alphabet shares fell 12.6%, their steepest one-day decline since 2004, according to the cited reports. The source material also points to investor concerns about free cash flow and spending, so the decline should not be attributed solely to AI Mode.
