Today’s interview is with Dan Lynch a Senior Manager, Insights and Analysis at M3 MI, the company behind the MARS Consumer Health Study and MARS Audiences.
Audience impact across health vertical
Which healthcare advertisers see the greatest impact from MARS audiences? Could you share an example of how health marketers have successfully utilized your data to achieve specific campaign goals, such as patient engagement, awareness, or adherence?
We’re seeing a clear shift in healthcare advertising away from generic, one-size-fits-all campaigns. With MARS, advertisers from pharmaceuticals, over-the-counter (OTC), health insurance companies, and hospitals are seeing the greatest impact by defining highly specific patient and caregiver personas and using those insights to build personalized media plans and deliver unique messaging by segment. As a result, our partners are seeing stronger engagement, increased ad recall, and more effective outcomes because they’re speaking directly to what matters most to each audience.

Media agencies who utilize the MARS Consumer Health Study to build their strategic marketing plans are seeing a great impact by then taking those strategic targets and activating them. Those who are not activating those audiences are really missing out on bringing their strategy to consumer screens.
Building stronger health campaigns with advanced segmentation
What key health-related audience segments does MARS offer?
While other competitors may offer caregiver segments by condition, we go further by layering engagement levels, such as caregivers actively involved in medical decisions or those who regularly discuss care with physicians. Similarly, for patients, we don’t stop at identifying over 60 health conditions; we add behavioral dimensions like whether they’re proactive in managing their health or primarily doctor-led. These nuanced attributes allow advertisers to craft personalized campaigns that resonate on a much deeper level. We can also look at patients that are willing to pay more for an Rx not covered by their insurance, which has been a trend with GLP-1s.

How can health advertisers use these segments to craft more personalized and effective campaigns?
Advertisers can use MARS’ advanced segmentation to move beyond simple demographics or condition-based targeting by layering behavioral and engagement attributes for greater relevance and impact. With MARS, a single condition can be the starting point for building multiple test-and-learn audiences to identify prime prospects. For example, GLP-1 patients have diverse treatment journeys; some pay out-of-pocket due to lack of insurance coverage, others switch brands for cost savings, and some purchase directly through patient websites. Each of these scenarios represents a distinct audience that can be created using MARS data, enabling highly personalized activation strategies.

Data sourcing and quality
How does MARS source and curate consumer data relevant to health audiences?
Our audiences are survey-based, first-party data built from the MARS Consumer Health Study and Kantar’s trusted LifePoints Panel. We do not use medical claims, insurance data, or personal health records; our data is 100% self-reported. The study has over 5,000 different healthcare data points used to create syndicated and custom audiences. Our syndicated audiences are curated based on marketplace trends (e.g., we’ve added more information on GLP-1s), client feedback for enhancements to the MARS study, and reaching audiences medical claims data cannot (e.g., caregivers, treatment satisfaction, act based on healthcare advertising).
What data quality standards do you follow, and how do you ensure consistency and reliability, especially for sensitive or regulated health-related data?
M3 MI is part of M3 Global Research which is committed to transparency and high-quality data with ISO (International Organization for Standardization) certifications. These certifications demonstrate that our research practices align with international regulations.
In a crowded data marketplace, what unique attributes set MARS apart, particularly for health advertisers?
We don’t just identify patients or caregivers, we uncover their motivations, preferences, and behaviors, enabling advertisers to build highly targeted and meaningful audiences that competitors simply can’t replicate.

The MARS Consumer Health Study offers an extensive range of data for audience building, spanning healthy living profiles, OTC, vitamins, and prescription purchasing behaviors, as well as media consumption habits and lifestyle activities.
How MARS ensures regulatory compliance
What measures does MARS take to maintain data privacy and regulatory compliance?
We take a privacy-first approach to exceed all Network Advertising Initiative (NAI), Health Insurance Portability and Accountability Act (HIPAA), and California Consumer Privacy Act (CCPA) regulations. Since the data to build our audiences is self-reported via the MARS Consumer Health Study, we do not use PII data. We also take the following steps to maintain data privacy and compliance:
- State regulatory compliance: We proactively exclude survey respondents for audience seeds from certain states with consumer privacy laws that preclude audience data use
- Consent and transparency: Survey panelists are required to double-opt-in to all data usage terms before participating in the MARS study. Our panel partner’s privacy policy clearly explains use cases such as look-alike modeling and audience creation.
- Privacy-safe modeling: Data is scaled using propensity models built from an offline, people-based national consumer database. All seed survey data is removed from final models to eliminate any risk of re-identification, ensuring respondents are never targeted directly based on their survey responses.

How do these efforts help advertisers navigate an evolving regulatory landscape while ensuring ethical standards?
By relying solely on double opt-in, self-reported data, and removing identifiers, we guarantee that our approach is 100% privacy-safe and compliant. This gives advertisers confidence that our audiences are built on ethical, transparent practices without compromising consumer trust.
Success stories
Could you share a recent success story where a health advertiser achieved significant campaign improvements using M3 MI’s MARS data? What were the key factors behind that success, such as ROI, engagement lift, or conversion rates?
One recent success story involved a diabetes medical device advertiser trying to breakthrough in a cluttered marketing landscape. Their initial broad, non-personalized media campaign delivered lower than expected digital engagement. To address this, the company conducted segmentation research and identified three distinct patient personas. However, the research lacked actionable media insights and a way to effectively reach these personas in the digital world.

That’s where MARS data came in. Using the MARS Consumer Health Study, M3 MI mapped the existing personas to uncover each group’s unique media habits. These insights enabled the media agency to design tailored strategies for each persona. Additionally, M3 MI built custom, propensity-modeled persona audiences for activation across CTV, social, and display channels, ensuring precise targeting and personalized messaging. This strategic shift to personalized persona marketing transformed the campaign from a one-size-fits-all approach to a patient-first model. The company saw a significant lift in website engagement and a measurable increase in ROI.
