Targeted job advertising with AI: high-risk and a discrimination risk

Short answer: Using AI to target job ads — deciding who does and does not see a vacancy — is named explicitly in Annex III, point 4 of the AI Act as high-risk. It is not an edge case. The reason is discrimination: an algorithm that shows a vacancy mostly to a certain age, gender or origin excludes others without anyone noticing. On top of that come the GDPR and the DSA.

Why this is high-risk

Recruitment begins before the application: with who sees the vacancy at all. Ad platforms optimise for "click likelihood", and that optimisation can lock onto demographic patterns — the technical role lands mostly with men, the care role mostly with women. The result is a biased applicant pool you never see, because the excluded group never got to apply.

The discrimination risk

This touches equal-treatment law directly. Even without deliberately targeting a protected characteristic, platform optimisation can produce indirect discrimination. See AI and discrimination in recruitment: responsibility lies with the employer, even when the platform performs the targeting.

What the GDPR and DSA add

Targeting is profiling, and thus processing of personal data with a valid basis and transparency (GDPR). The Digital Services Act also bans ads based on special-category data and profiling-based ads to minors, and requires platforms to make ads recognisable. If you recruit through large platforms, these rules reach you via the advertising terms.

What to do

• Treat job-ad targeting as high-risk — with human oversight and monitoring for skewed outcomes.
• Target broadly, not narrowly: avoid demographic narrowing and don't let the platform optimise unchecked.
• Check the reach figures for unintended exclusion (age, gender, region).
• Record the basis and the trade-offs — you need them in a complaint.
• Combine with your broader recruitment approach and CV screening; the whole funnel falls under the same regime.

The fairest selection starts with fair reach. An algorithm that decides who sees your vacancy helps decide who can be hired — which is exactly why the law is strict about it.
