The EU requires clear labels on online political advertisements

The test

The European Parliament and Council's Regulation (EU) 2024/900, published in the Official Journal on 20 March 2024, sets EU-wide rules on political-advertising transparency and targeting. Article 11 requires a political advertising publisher to make each ad available together with a statement that it is political advertising, its sponsor's identity, any linked election or referendum, whether it used targeting or ad-delivery techniques, and a transparency notice — or a clear indication of where one can be retrieved. Under Article 30, the regulation applies from 10 October 2025, though two narrower provisions applied from entry into force in 2024.

What the evidence says

The text distinguishes an ad's on-ad label from its transparency notice: the label must be clear, salient and unambiguous, while the fuller notice can sit behind a link. Article 11 places the completeness duty on the publisher — the entity making the ad available — rather than solely on the sponsor who paid for it. A recital connects this scheme to the Digital Services Act, stating that publishers that are very large online platforms should make each notice's information available in the ad repositories Article 39 of Regulation (EU) 2022/2065 already requires them to maintain, rather than creating a separate channel.

The sample and the variance

This record describes the regulation's own text, not any platform's implementation, and not a measurement of political-ad spending or targeting in practice. Obligations apply specifically to political advertising publishers and the wider chain of political advertising service providers as the text defines those terms; a service outside that definition sits outside its scope even if it carries other paid content. The main application date is 10 October 2025, so this entry describes what the text requires, not whether any specific publisher's labeling and notices in fact meet it.

What to try next

A marketer or observer reviewing a political ad in the EU can check it against Article 11's list — statement, sponsor identity, linked election, targeting disclosure, notice access — as a documented checklist, rather than accept a general disclaimer as sufficient. Where the publisher is a very large online platform, the same observer can check whether the notice information also appears in its Article 39 repository, since the regulation treats that repository as required, not optional. This is an editorial checklist, not a certification of any publisher's compliance.

• Does the advertisement in question meet the regulation's definition of political advertising, or does it fall outside that defined scope?
• Is the transparency notice's information actually retrievable from the advertisement, and does it match what Article 12 requires it to contain?
• For a very large online platform, does the same disclosure also appear in its Digital Services Act ad repository, as the regulation's recitals anticipate?

Regulation (EU) 2024/900's own text sets a specific labeling and notice standard with a fixed application date; whether a given political advertisement meets that standard is a separate, checkable question the regulation does not answer for any single case.
