Healthcare Marketing Reimagined
medizinonline.com reaches physicians outside the platform, with verified identity.
Why Extended Reach?
Like everyone else, physicians read NZZ, 20 Minuten, Blick & Co., not just professional portals.
According to the Therapeutic Products Act, Rx advertising may only reach professionals, never the public.
medizinonline securely transfers the verified professional identity to other environments like 20min.ch.
How it works
Nowhere else is it shown.
Access to medizinonline is granted only with a copy of an ID and GLN number.
An encrypted identifier remembers the specialty, never the name or email.
If the same person visits e.g. 20min.ch, the identifier is recognized there.
The professional ad appears only there, invisible to everyone else.
Technical operation in detail
The physician authenticates at login; the GLN number was checked against the professional register during registration. After successful verification, medizinonline creates a unique, verified user ID on the server side.
Upon login, medizinonline sets its own (1st-party) cookie on the server side, persistent, independent of 3rd-party blocking.
Example (Simplified)HttpOnly & Secure: exclusively readable server-side. Contains an encrypted, pseudonymous ID and coded characteristics, anonymized, no inference to the person.
If the same physician visits e.g. 20min.ch, the synchronized ID becomes visible in the bid request, as is standard in programmatic advertising. Only the certified Ad-Tech platform knows which segment it corresponds to, for everyone else it remains meaningless.
The ad is delivered directly to the verified, recognized person. No segment, no access to our backend, no delivery, no fallback to assumption.
Only medizinonline and PPM can map the cookie value to a professional segment. A physician recognized via the cookie is treated exactly the same as a logged-in physician on medizinonline: the same verified professional affiliation, just outside the platform.
How matching and protection work technically
A cookie is strictly bound to its setting domain via Same-Origin-Policy. 20min.ch cannot technically read our medizinonline cookie, the browser itself enforces this, not just a promise from us.
Upon login, the certified Ad-Tech platform additionally sets its own cookie on its own domain, separated from ours.
Mapping (Server-side, once at login)This link is created once server-side at login, our own cookie is never transferred to the Ad-Tech platform or read by it.
On 20min.ch, the ID in the bid request is visible to all participating systems, this is programmatic standard. However, the inference to "Specialty X" is only possible for us, because only we have the mapping table.
Only the contractually bound Ad-Tech platform may request this resolution, authenticated via API key and fully logged.
Data processing, not self-use.
The Ad-Tech platform is a data processor according to Art. 28 GDPR, contractually bound, bound by instructions, auditable. Mapping and cookie are time-limited; upon revocation, the mapping is immediately deleted server-side.
Verified. Minimized. European.
Registration only with ID copy and GLN number, no self-disclosure, no probabilistic targeting.
Processing and storage exclusively in the EU and Switzerland, no transfer to third countries like the USA.
Only an encrypted identifier and the specialty leave medizinonline, never name, email or patient data.
The pharma company only receives campaign delivery and reporting, never access to identifiable personal data.
Recognition = Login.
A physician recognized by the 1st-party cookie is treated exactly the same outside of medizinonline as a logged-in physician, the same verified professional affiliation.
