Doximity: The US Physician Network for Pharma Media

The assessment

Doximity is the largest professional network for US physicians; by its own account it reaches most of the US medical profession. Members are verified against the NPI registry, and ad placements sit in the newsfeed, professional newsletters and around telehealth tools. Our view: the cleanest HCP identity in the US market. Nowhere else.

Audience model and targeting

The basis is membership instead of ad IDs: verified profiles with specialty, region and hospital affiliation. Targeting runs, per the vendor, on specialty, geography and further professional attributes. Data sources are registry and profile data; prescription data is not part of the targeting itself.

Activation and measurement

Buying is managed via insertion orders. External DSP access? None. On measurement the vendor names audience verification and Rx lift studies via partners. Little of that can be recomputed independently; teams that want their own attribution need clean click-to-CRM chains.

Compliance and review

Before any booking: legal and compliance review required. The setup lives in the US regulatory frame; statements about data conformity are vendor claims, not findings of ours. For EU constellations the model lacks the foundation, see Article 9 GDPR.

Common implementation mistakes

• Click destinations without UTM discipline, so the measurement chain ends at the portal.
• US campaign KPIs transferred to EU planning without validation.
• No own conversion tracking behind the insertion order.
