Big Tech Q3: Search holds ground, as retail media networks challenge Google–Meta duopoly

For all the noise about AI, automation and attention spans shorter than an Instagram Reel, Search remains the one ad format that refuses to die. If anything, it’s thriving. Alphabet just logged its first-ever $100-billion quarter, with advertising contributing roughly $74 billion (three-quarters of total revenue) and Search alone accounting for $56 billion of that. Even as AI reshapes how users discover, click, and convert, Search has quietly become the performance backbone of the digital economy.

Alphabet’s Q3 2025 results underline this reality. The company’s advertising business grew 11 percent year-on-year, powered by the same engine that has defined digital marketing for two decades: intent. When users come looking for something, Google’s AI now makes sure they find (and buy) it faster. YouTube, meanwhile, pulled in $10.2 billion in ad revenue, up 15 percent, thanks to better Shorts monetization and Connected TV (CTV) momentum. Google Cloud surged 34 percent, giving Alphabet the balance sheet to keep throwing billions at AI infrastructure, even as investors grumble about capex.

Across Silicon Valley, the same formula is repeated with minor variations. Microsoft clocked $77.7 billion in revenue (+18 percent YoY) and $49.1 billion from its Cloud division (+26 percent), confirming that the real money in AI is still being made by the ones selling the picks, shovels, and GPUs. Meta’s $51.24-billion quarter (+26 percent) was driven by a 14 percent rise in impressions and a 10 percent bump in price per ad, its strongest pricing recovery since the Apple ATT shock.

Messaging commerce was the new breakout, with click-to-WhatsApp ads up 60 percent year-on-year. Amazon, predictably, turned its retail moat into an advertising machine: $17.7 billion in ad revenue, up 24 percent, powered by retail media growth and the first full quarter of Prime Video ads.

So, what do these earnings tell us? That the global ad market is consolidating around three overlapping forces: Search, short-form video and retail media, all of which now run on AI.

For marketers, Search continues to deliver the highest intent and the lowest wastage. Google’s new “AI-overview” results, which blend generative summaries with sponsored listings, are still in early testing, but the trajectory is clear: ad formats are becoming richer, more contextual, and more conversational. Instead of killing Search, AI is making it more valuable. Performance budgets that might have drifted toward experimental generative channels are returning to the one place that guarantees a measurable click-to-cart path.

Meanwhile, video remains the arena where the duopoly’s grip is strongest. YouTube’s double-digit growth and Meta’s revived ad pricing confirm that vertical video and CTV are now the default creative formats for digital campaigns. Advertisers are building modular assets designed for Shorts, Reels, and living-room screens, balancing discovery with conversion in the same frame. The creative arms race between YouTube and Meta is less about audience overlap and more about attention compression. And how to make a 15-second window feel like a story and a sales pitch simultaneously.

The more interesting story, however, is unfolding on the retail side. Amazon’s ad business is scaling faster than any other platform’s, as retail media networks evolve from experimental add-ons to core performance channels. The combination of intent, inventory, and closed-loop measurement gives Amazon a full-funnel advantage that neither Google nor Meta can easily replicate. With Prime Video ads now live, Amazon has effectively connected brand storytelling to basket conversion within its own walls.

In India, this shift has immediate implications. Quick-commerce and e-commerce platforms (Blinkit, Swiggy Instamart, Zepto, Nykaa, Flipkart) are building their own miniature retail media ecosystems, offering advertisers first-party data and instant purchase outcomes. What Amazon has built at global scale, these players are replicating locally: a high-intent environment with deterministic attribution. For FMCG and D2C brands, that means the ability to measure every rupee from impression to checkout, a transparency the open internet still struggles to provide.

Meta’s messaging commerce push, with click-to-WhatsApp up 60 percent, fits the same pattern. The future of digital advertising is moving closer to the transaction, whether that’s a WhatsApp chat, a quick-commerce basket, or a Buy Now button embedded in an AI-generated recommendation. Retail media and conversational commerce are not new categories; they’re the logical conclusion of performance marketing’s obsession with signal fidelity.

But this also means the old duopoly is being quietly challenged from both ends. Search and social still dominate top-line spend, yet retail media networks are claiming a growing share of mid-funnel budgets. Every product-based platform, from grocery apps to travel portals, is becoming an ad platform. As these networks multiply, the traditional separation between media and commerce collapses, giving marketers more ways to buy reach but also more data silos to reconcile.

The second-order effect of this transformation is creative. With AI now powering automated bidding, audience expansion, and creative iteration across all major platforms, the differentiator isn’t the algorithm; it’s the input. Advertisers who feed high-quality first-party data and test modular creative variations are seeing better yield from the same budgets. The lazy assumption that AI will do the work is already being punished by rising CPCs and tighter competition.

Heading into the holiday quarter, CPMs are firming up across Search and retail media. Alphabet, Meta, and Amazon all flagged higher advertiser demand and better conversion quality in their earnings calls. That’s partly macro recovery, partly AI optimization, and partly marketers shifting spend into platforms with stronger attribution. With CFOs demanding proof of performance, the pendulum has swung back to measurable media.

For agencies and brands, the playbook is becoming clearer. Anchor performance in Search, where intent still drives scale. Feed growth budgets into short-form video and CTV, where attention lives. Test retail and messaging commerce aggressively, because that’s where signal quality and purchase proximity intersect. And invest in creative iteration, because the next battle won’t be for impressions, it’ll be for relevance inside AI-curated feeds.

In other words, Search may still rule the roost, but the map of digital advertising is being redrawn beneath it. Retail media networks are the fastest-growing frontier, armed with first-party data, purchase signals, and the promise of closed-loop attribution. The Google-Meta duopoly isn’t collapsing. Rather it’s being flanked by a new generation of commerce-driven ecosystems that understand intent as well as, or better than, the incumbents.

If the last decade was about owning the audience, the next one will be about owning the checkout. Search will always tell us what people want. Retail media will tell us what they actually bought. And for advertisers trying to bridge that gap, the message from Big Tech’s Q3 earnings is simple: the age of speculative spend is over; the age of signal-driven certainty has begun.
