Europe Rewrites the Rules of Personalisation and Meta Feels the Price

Meta's advertising sales have weakened since the European Union introduced options for less personalised advertising at the beginning of the year. The immediate shock lies in the economics of targeting: when users can limit the use of personal signals, the company has fewer reliable means to predict and influence purchasing decisions, and advertisers must work harder to earn each response.

The friction is institutional as well as commercial. European privacy rules have sought to place meaningful limits on the accumulation and deployment of personal data, while Meta's advertising system depends on the opposite proposition, that a vast reserve of inferred interests can be converted into commercial certainty. The new formats expose the cost of that arrangement. Consent, identity and targeting can no longer be treated as a single commercial problem, and regional rules now shape product choices that once appeared global by default.

The downstream casualties are likely to fall unevenly. Large advertisers may transfer spending toward channels that still offer granular targeting, while smaller firms could benefit from less personalised options that are cheaper to buy. Meta, meanwhile, faces pressure to prove that advertising can remain valuable without relying on surveillance so extensive. The result is a lasting change in the price and quality of attention across Europe's digital markets.
