Alphabet said Search revenue grew 12% to $63.35 billion in the third quarter, down from 17% in Q2, and named lower AI Mode monetization as one reason.

If you run a high-ticket Shopify store, Google Shopping and Search are probably your biggest ad line. Per Search Engine Journal, your existing Shopping, Performance Max and Search campaigns are eligible for the new AI Mode ad placements by default and cannot opt out of them separately, so Google’s push to monetize that surface lands on your cost per sale whether you touched a setting or not.

Alphabet reported on Oct. 28, 2026. Here is what the numbers and the call said, how growth got from 19% to 12% in three quarters, and what I would change in a Google Ads account before Black Friday traffic arrives. I keep this beat current at Ecommerce Paradise. The thread starts with my Oct. 20 post on Google testing ads in AI Mode.

Alphabet Q3: Search Revenue Up 12% to $63.35B, Slowest of 2026

Alphabet reported after the market closed on Wednesday, Oct. 28. Total revenue was $127.6 billion, up 25% from $102.3 billion a year earlier, according to 9to5Google. Operating income was $40.58 billion, and net income was $26.17 billion against $34.9 billion in Q3 2025.

Search and other revenue was $63.35 billion, up 12% from $56.57 billion a year earlier, per StockTitan’s earnings breakdown. Growth was 19% in Q1 and 17% in Q2. Search Engine Journal noted that revenue was essentially flat against Q2’s $63.27 billion. YouTube ads came in at $11.2 billion, up from $10.26 billion.

Philipp Schindler, Alphabet’s chief business officer, said lower AI Mode monetization was one of three reasons for the slowdown, according to Search Engine Journal. On the call he said, “the strong growth in AI Mode queries had an impact because of the lower monetization we were seeing in AI Mode,” per the Investing.com call transcript. He did not say what AI Mode was lower than or how much revenue it affected.

The other two reasons came from CFO Anat Ashkenazi: currency, which was a small headwind year over year and a larger one against Q2, and a tougher comparison, since search growth accelerated through the second half of 2025. For Q4 she expects a slightly larger currency headwind and said that lapping last year’s acceleration will keep pressure on growth.

Schindler also said Google is “now scaling ads within both AI Overviews and AI Mode to more users and more queries.” Search Engine Journal reports ads in AI Mode are expanding to Australia, Canada, India, Kenya, Malaysia, New Zealand, Nigeria, Pakistan, the Philippines and Singapore, with the U.K., Brazil and Mexico planned for Q4. Multiturn ads for follow-up questions are launching in the U.S.

On shopping, Schindler described “the biggest update to product listing ads in a decade,” built around AI features that help shoppers buy. He said “AI Max and Performance Max continue to see strong adoption” and that the Universal Commerce Protocol “is being rapidly adopted by retailers,” per the same transcript.

Shashi Thakur, VP and GM of Google Search Ads, said “click-through rates are already similar between sponsored and organic product list items within AI Mode.” The supporting data is internal Google data from U.S. users between Aug. 20 and Sept. 3, 2026.

The profit line looked worse than the business. Diluted EPS fell to $2.12 from $2.87, but operating income rose 30%. Ashkenazi said other income and expenses was negative $8.2 billion, “due primarily to unrealized loss from our investment in SpaceX.” Capex was $51.36 billion against $23.95 billion a year earlier, per StockTitan. Shares fell about 9.4% in after-hours trading, and CNBC’s headline said Alphabet “sinks 10%” while holding 2026 capex unchanged and expecting a significant increase in 2027.

From 19% to 17% to 12%: How Google Search Growth Cooled

The slide has been visible for two quarters. Search grew 19% in Q1, then 17% to $63.3 billion in Q2, up from $54.2 billion a year before, per PPC Land’s Q2 coverage. Alphabet’s CFO warned in July that it would be lapping a Search acceleration that began in Q3 2025, so the tougher comparison was flagged ahead of time.

In that Q2 report Google said AI Mode passed one billion monthly users and introduced new placements called Direct Offers, Highlighted Answers and contextual sitelinks. It also said AI Max had about half a million advertisers, with Schindler claiming an average of 15% more conversions or value on Search. That figure is Google’s own measurement, and PPC Land noted that independent tests from November 2025 found a higher cost per conversion for AI Max.

This quarter’s version of the story is the same tension. Query growth is the strongest it has been in five years, according to CEO Sundar Pichai, who framed Google’s priority as “building the best Search user experience, followed by monetization.” Schindler said most AI Mode queries are incremental and many are upper-funnel, which he expects to create more monetization opportunities over time.

There is a counterpoint, and it comes from inside the call. J.P. Morgan analyst Doug Anmuth questioned the gap between query growth and search ad revenue growth, per Search Engine Journal. If queries are growing at a five-year high and Search revenue is flat from the prior quarter, the new queries are probably not paying the way old ones did.

Google’s defense is reasonable on its face. Operating income grew 30%, the EPS miss traces to a non-operating investment loss, and Thakur’s click-through data says sponsored product results perform close to organic ones in AI Mode. One quarter of slower growth is also not a trend, and Search revenue still grew double digits against a large base.

Compare that with Meta. Its ad revenue rose 26% to $63.06 billion in Q3 with price per ad up 23% in the U.S. and Canada, according to PPC Land’s report on Meta’s Oct. 21 results. Meta’s ad revenue is now almost the size of Google’s Search revenue, and it is growing more than twice as fast. I covered what that means for conversion volume in Meta’s note that ad sets under 50 weekly conversions cost 28% more.

One gap remains in the reporting I reviewed. None of it gave cost per click or paid click volume for the quarter, so you cannot tell from Alphabet’s numbers whether advertisers paid more or less per click. Your own account is the only place that answer lives.

Google has been rebuilding the shopping path piece by piece. I covered Newegg turning on Google checkout in Gemini and AI Mode. Then came Google Universal Cart going live for Shopify.

What Lower AI Mode Monetization Means for a High-Ticket Budget

This section is my opinion, not reporting. I am not an investment or financial advisor, and nothing here is advice on Alphabet stock.

My read is that Google is choosing query growth over ad revenue for now and plans to catch up by putting more ad formats into AI Mode. Your campaigns are the inventory it uses to do it. That is a reasonable business decision for Google. For a store owner it creates a reporting problem, because Search Engine Journal says AI Mode results are combined with the rest of Search in standard reporting. You cannot see whether those clicks convert worse.

Here is hypothetical math, labeled as such. Say a store spends $15,000 a month on Shopping and Performance Max at a 5.0 ROAS. That is $75,000 in revenue. At a 25% gross margin, gross profit is $18,750 and profit after ad spend is $3,750. Now assume 20% of your clicks start coming from AI Mode surfaces and convert 15% worse than before. Blended revenue falls 3%, to $72,750. Gross profit drops to $18,187.50 and profit to $3,187.50. A 3% revenue dip just erased 15% of your profit.

Those inputs are invented, so run your own numbers. The shape is what matters. When margin after product cost is thin, a small drop in conversion rate hits profit far harder than it hits revenue. I would treat any sustained slide in conversion rate as an alarm instead of noise.

Schindler’s own description matters here. He said many AI Mode queries are upper-funnel. For a $2,000 patio set or a $4,000 treadmill, an upper-funnel click is a person asking questions, not a person holding a credit card. Those visitors may come back through brand search or a phone call, and last-click reporting will give the credit to someone else. My guide to turning Google Shopping clicks into high-ticket sales covers the follow-up that makes those visitors worth paying for.

Set thresholds before the changes reach you. Mine would be a conversion rate that drops 10% or more against your prior 28 days and stays there for 14 days, or a cost per acquisition that rises 15% for a full week. If either triggers, cut that campaign’s budget by 20% and see whether it recovers. If neither triggers, leave it alone, because Google itself advises against multiple target changes within one conversion cycle, per PPC Land. smec’s finding that a Google bid change wiped out a 20% ROAS cushion shows how fast the cushion goes.

The strategic point is about dependence. Google told investors this week that the surface growing fastest is the one it monetizes least, and it is the one you cannot turn off. A store that gets 90% of its leads from Google Ads has no vote in that decision. A store with a decent email list in Klaviyo has somewhere to send budget when the paid math slips. So does a store with organic rankings tracked in Mangools.

Organic is not a free pass. Semrush found AI Overviews on 85% of ecommerce keywords, as I wrote in my breakdown of the Semrush AI Overviews study. Meanwhile one study put ChatGPT at 0.62% of Google’s organic traffic, which I covered in the ChatGPT versus Google organic numbers. Google is still where the traffic is. You are managing a dependency, not escaping it.

A competitor-research tool like Semrush helps you see which of your keywords are exposed to AI answers before you decide where to put budget.

Two more uncertainties are worth stating. Google’s click-through claim comes from a 15-day window of its own U.S. data, and conversion rate is what pays you, not click-through rate. Also, the country list for AI Mode ads matters mainly to stores that sell abroad. Do not rebuild your whole account on one earnings call.

5 Moves for Your Google Ads Account Before Black Friday

Five things to do this week, in order:

  1. Export 28 days of campaign data for Shopping, Performance Max and Search, plus the 28 days before it. Record conversion rate, cost per acquisition and ROAS for each campaign type, then save it as your baseline before Nov. 1. Everything else on this list depends on that file.
  2. Check your negative keywords and brand exclusions. Search Engine Journal says both still apply to AI Mode and AI Overviews even though you cannot target those surfaces separately. If you run AI Max, read the search terms report against Google’s new link between AI Max search terms and headlines.
  3. Write your stop rule in a doc today, using the thresholds from the section above or your own. Decide what you will cut and by how much when a campaign breaches them, so you are not negotiating with yourself at 11 p.m. on Black Friday.
  4. Audit Performance Max assets before Dec. 4, when Google turns on landing page image extraction by default for new campaigns, per PPC Land. My note on PMax sourced videos turning on by default covers the related video default. Also review your feed against the Google UCP hub in Merchant Center so checkout surfaces can use it.
  5. Move a test slice of 10% to 15% of Google budget into Meta’s product browsing in existing ads or email, and compare blended acquisition cost over two weeks. If you want a second opinion on the split, Explore Turnkey Builds.

Frequently Asked Questions

How much did Google Search revenue grow in Q3 2026?
Search and other revenue grew 12% to $63.35 billion from $56.57 billion a year earlier, per StockTitan. That compares with 19% in Q1 and 17% in Q2.

Can I opt out of ads in AI Mode?
Search Engine Journal reports that existing Search, Shopping and Performance Max campaigns are eligible by default and cannot opt out separately. Negative keywords and brand exclusions still apply, so use them. My earlier post on AI Overviews on 80% of brand searches shows why brand terms matter.

Do AI Mode clicks convert worse than normal Search clicks?
Google has not published conversion data for AI Mode. Thakur’s claim is about click-through rate, from Aug. 20 to Sept. 3 U.S. data. Watch your own conversion rate against your baseline, and read why high-ticket Google Ads need a complete conversion system if your clicks are not turning into calls.

Did Alphabet miss earnings because of Search?
Not mainly. Ashkenazi said negative other income of $8.2 billion, tied to an unrealized loss on a SpaceX investment, drove the net income and EPS decline, while operating income rose 30%. The sources I reviewed do not pin the share drop on one cause, and CNBC’s headline pairs it with the capex outlook.

Should I spend less on Google Ads?
Not on one earnings report. Set a baseline, set thresholds, and cut only where your own numbers break them. My post on Google Ads letting retailers multiply new customer value 5x covers one lever that can help margin without cutting spend.

Is high-ticket dropshipping still worth it with ad costs shifting?
The model depends on healthy margins per order, and that is why I pick niches by margin first. Start with what high-ticket dropshipping is and how to start. Then pull my free high-ticket niches list.

What is Google’s Universal Commerce Protocol?
It is Google’s checkout standard for AI shopping surfaces, which Schindler said retailers are adopting rapidly. You can see how it shows up in Merchant Center in Google’s UCP checkout hub.
