⚠ Privacy Walls & Signal LossModerate threat

Intent targeting depends on a rich flow of data about users, and the danger is that the world is steadily walling that data off. Privacy regulation like Europe's rules, the deprecation of tracking cookies (a death Chrome scheduled in 2020, delayed for years, and finally called off in July 2024¹), platform-level privacy features, and rising public wariness all cut into the signal that lets Google target so precisely. As the data thins, the ads grow less accurately aimed, and less accurate aim is worth less money.

This is dangerous because precision is the whole premium. If targeting degrades toward the blunt, demographic guesswork of old-fashioned advertising, then Google's ads lose the very edge that justifies their price, and the extraordinary efficiency of the machine erodes. The threat is secular and one-directional: privacy expectations only tighten, and each tightening removes another signal the targeting relied on.

Google's bulwark is that its own vast, first-party data — what people do inside Google's own products while signed in — is far more resilient to these changes than the third-party tracking that rivals depend on, so privacy walls can actually hurt competitors more than Google. And Google is investing heavily in privacy-preserving and AI-driven targeting that extracts signal without the old intrusive tracking.

File it as moderate. The privacy reckoning genuinely erodes the data richness that makes intent targeting so precise, and it advances steadily through regulation and platform change — but Google's first-party data and its scale make it comparatively well-insulated, and it may emerge relatively stronger as the third-party tracking its rivals lean on disappears. The signal thins; Google's share of what remains may even grow.
