Checkmate? How Amazon's War on Google Ads Triggered Google's Alliance with Criteo in a Chess Match for the Future of Commerce

Forget the cold war. The platform war just went nuclear.

For years, the titans of tech have been playing a quiet game of chess for control of the digital shelf. In the last few weeks, that quiet game became a declaration of war. Two seismic events, occurring just weeks apart, were not unrelated tremors but a coordinated one-two punch that has fundamentally bifurcated the retail media landscape.

First, Amazon, the undisputed empire of eCommerce, abruptly pulled its massive advertising spend from Google Shopping, effectively raising the drawbridge to its walled fortress.

Then, in a stunning counter-move, Google announced a strategic alliance with commerce media platform Criteo, uniting over 200 retailers into a federated coalition designed to fight back.

This is not just another headline. This is the strategic realignment we’ve been waiting for. The world of retail media has officially been split into two opposing powers: The Empire and The Alliance. For brands, the game has changed overnight. Navigating this new world order is no longer optional—it is the only path to survival and growth.


Act I: Amazon Declares War

Amazon’s exit from Google Shopping was a masterclass in strategic arrogance, and for good reason. This wasn't a cost-cutting measure; it was a calculated act of defiance. Within 48 hours, Amazon's impression share in Google Shopping auctions plummeted from as high as 60% to zero across all major global markets.

Why pay a rival for traffic when you are the destination?

By pulling its estimated $50 million+ annual spend, Amazon achieved three strategic goals in a single, brutal move:

  1. It Starved a Rival: It stopped funneling millions directly to Google, its primary competitor for advertising dollars and e-commerce supremacy.
  2. It Captured the Entire Journey: By forcing shoppers to start and end their journey within its ecosystem, Amazon retains complete control over the invaluable first-party data that fuels its advertising flywheel. In a privacy-first world, this data is the ultimate currency.
  3. It Forced Brands’ Hands: The move sends a clear message to brands and sellers: the traffic that once came from Google Shopping must now be bought and paid for inside Amazon’s own ad platforms. The walls of the garden just got higher, and the toll to enter just went up.

This is more than a simple budget reallocation. This is Amazon betting on its own gravity, confident that its ecosystem is now powerful enough to exist as a self-sustaining universe, independent of the open web.


Act II: Google Assembles The Alliance

Google's alliance with Criteo is the necessary counter-move to Amazon's declaration of independence. Google needs to prove that the world outside the Amazon fortress is still the largest, most vibrant, and most profitable place to find consumers. The combination of Google’s vast, high-intent audiences (search, YouTube, Gmail) with Criteo's unified network of retailers, and crucially, their first-party retail data, is designed to create a powerful, data-rich alternative to Amazon.

The Alliance's strength is its scale and its open architecture. The alliance with Criteo brings together:

  • Google's Reach: The undisputed leader in intent-based search and high-impact CTV/video advertising.
  • Criteo's Commerce Data: An immense and growing pool of retail shopping data from over 200+ global retailers.
  • The Unifying Technology: A federated platform that allows brands to leverage this collective first-party data for precise targeting and measurement across the open web, where most of the purchase journey still begins.

The Strategic Implications for Brands: Choosing Your Chessboard

Brands must now run sophisticated, bifurcated media strategies to ensure survival. Ignoring one side of the board is a guaranteed path to decline.

StrategyThe Empire (Amazon)The Alliance (Google/Criteo)
The GoalConvert existing, high-intent shoppers within the walled garden.Intercept and influence shoppers earlier in the journey (discovery, research, consideration).

The FocusConversion and Market Share Capture.Incremental Reach and Demand Generation.
The MetricROAS on Amazon sales.Cross-Channel Incrementality and Brand Lift.

The core challenge is ensuring that these two strategies—the Empire and the Alliance—are not just running in parallel, but are in strategic harmony. Your off-Amazon spend (the Alliance) must drive incremental traffic to Amazon and other retailers (the Empire). Your Amazon data (the Empire) must inform your audience strategy on the open web (the Alliance). The two systems must be a feedback loop, not a conflict.
