A deep dive with an Experian partner, M3 MI

by Experian Marketing Services 8 min read December 11, 2025

At A Glance

M3 MI's MARS Consumer Health Study empowers healthcare advertisers to create personalized campaigns by offering nuanced audience insights. By layering behavioral and engagement attributes, MARS enables accurate targeting, driving stronger engagement, improved ad recall, and measurable campaign outcomes across connected TV (CTV), social, and display channels.

In our Ask the Expert Series, we interview leaders from our partner organizations who are helping lead their brands to new heights in AdTech. 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.

Experian at CES 2024: Four key trends in advertising

Every year, the Experian team attends the Consumer Electronics Show (CES) in Las Vegas, to immerse ourselves in the world's most significant consumer tech showcase and stay at the forefront of the latest technological advancements and innovations that shape the AdTech industry. This year's event was a vibrant melting pot of innovation and vision, from streamers taking a bigger bite of the advertising pie to the emergence of AI-powered solutions and drone delivery services. Amidst these advancements, the dynamic interplay of technology, media, and advertising raised important questions, especially in the context of evolving regulations and cookie deprecation. During CES, we captured insights from various thought leaders, and in the coming months, we'll be sharing these valuable perspectives with you. Watch the video below for full insights coming from our content studio onsite during the event. Or, keep reading for a recap on four key trends from CES and what they mean for your business in 2024! “My first CES was a major success. You could feel the buzz in the air as new ideas and partnerships were being created within and across industries. The intersection of the different players within retail media, connected TV, retail technology, the demand and supply-side, and agencies all in an ever-changing world of regulation and privacy begs for a solution that can maximize a successful outcome for all.”anne passon, sr director, sales, retail & cpg 1.  Audience targeting: How first- and third-party data work together A central theme at CES was the importance of audience targeting, highlighting the crucial role of first-party data. However, it’s clear that to maximize its potential, this data needs to be augmented with sophisticated identity solutions and enriched with third-party insights, all while navigating the complexities of privacy regulations. This integrated approach is vital to understanding audiences and for creating more effective marketing strategies that comply with privacy regulations. 2. Standardizing metrics in retail media networks The challenges around retail media networks, particularly in terms of standardizing metrics like incremental return on ad spend (iROAS), were a hot topic at CES. This complexity around this topic underscores the need for neutral, expert third parties to help bring clarity and consensus, aiding businesses in navigating this multifaceted domain. 3. The challenge of switching data solutions Discussions covered the broader challenges associated with transitioning to new data solutions. For businesses, this involves a critical assessment of the benefits versus the costs and complexities of adopting new platforms or systems. This decision-making process is increasingly significant as data strategies become integral to marketing success. 4. Identity solutions in a cookieless future With the industry moving toward a cookieless future, the spotlight at CES was on the importance of robust identity solutions. Understanding the functionality and necessity of various universal IDs is essential to minimize data loss and maintain effective targeting. Investing in flexible and adaptable identity solutions like the Experian Graph is essential to maintain effective targeting and audience engagement in this new landscape. Announcements and advertising innovations at CES 2024 CES was a stage for significant announcements and innovative marketing initiatives: Criteo and Albertsons announced their collaboration in retail media. Instacart's partnership with Google for enhanced shopping ads and AI shopping carts. NBCUniversal's advancements in streamlining programmatic advertising. Brands like Netflix, LG, Freewheel, and Amazon Ads also captured attention with their creative marketing strategies, ranging from unique collaborations to themed promotions and captivating events. These insights from CES provide a glimpse into the future of technology, media, and advertising. They highlight the need for adaptability, innovation, and informed decision-making in these dynamic industries, especially in the context of privacy regulations.
