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.

Agencies, platforms, and marketers stand at the crossroads of transformation, as privacy regulations tighten, technology accelerates, and consumer behaviors evolve. Yet these challenges also present extraordinary opportunities. Our 2025 Digital trends and predictions report highlights five trends that will shape 2025 and digs into: What’s changing in the market How to keep learning about your customers How to reach your customers in different places How to measure what’s really working along the way In this blog post, we’ll give you a sneak peek of three of these trends — from cracking the code of signal loss to tapping into the buzz around connected TV (CTV) and stepping up your omnichannel game. Think of it as a taste test before the main course. Ready for the full menu? Download our report to get the lowdown on all five trends. Download now 1. Signal loss: A rich appetizer of alternate ingredients As traditional cookies crumble, marketers need fresh ingredients to keep the flavor coming. Already, about 40% of browser traffic doesn’t support third-party cookies, and marketers are spicing things up with first-party data, alternative identifiers like Unified I.D. 2.0 (UID2) and ID5, and contextual targeting strategies. In fact, 50% more of our clients received alternative IDs (UID2, ID5, Hadron ID) in their Digital Graph in 2024 compared to 2023. The number of alternative IDs resolved to individuals in our Digital Graph increased by 30% year-over-year – as everyone looks beyond the cookie jar. There is no secret sauce to replace cookies. Instead, expect a multi-ID recipe that brings together different identifiers, unified by an identity graph. This approach turns a fragmented pantry of data into a cohesive meal, giving you a complete view of your customer on every plate. 2. The rising power of CTV: A hearty entrée of opportunities CTV is quickly becoming the main dish on the streaming menu, as viewers load up on their favorite shows. While CTV is slated to make up 20% of daily U.S. media consumption by 2026, advertisers are still holding back on pouring in the ad spend. To unlock its full flavor, marketers need to whip up solutions like frequency capping and unified audience activation. Although CTV will account for 20% of daily U.S. media consumption by 2026, it’s projected to command only 8.1% of ad spend. Frequency capping and unified audience activation solutions will be key to unlocking CTV’s full potential. By 2025, nearly half of CTV "diners" will choose free ad-supported streaming TV (FAST). Marketers need strategies to prevent ad overexposure. With 50% of U.S. consumers avoiding products due to ad overload, and 30% of marketers willing to increase their CTV spend if frequency capping improves, unified identity solutions help ensure every impression is served just right. 3. Omnichannel: A flavorful fusion plate No one likes a one-flavor meal. Marketers are moving beyond single-channel “side dishes” to omnichannel “fusion feasts” that blend direct mail, digital, CTV, and retail media networks (RMNs) into a truly cohesive culinary experience. Even though only 21% of global B2C professionals currently put omnichannel at the top of their shopping list, the growing demand for seamless, audience-first campaigns is heating up. In 2025, having an audience-first approach will be like having a perfect pairing for every course. Unified identity solutions act as your master sommelier, ensuring that each channel complements the next, and every customer enjoys a well-rounded, memorable journey. Vertical trends: A dessert sampler from four unique kitchens Different markets have their own signature flavors. In Auto, crossover utility vehicles (CUVs) claim 51% of new vehicle registrations, and consumers in the 35-54 age group and families are the primary buyers. Automotive marketers should prioritize CUV advertising with a strong focus on family-oriented and income-appropriate messaging In Financial Services, marketers need to anticipate shifts in consumer behavior tied to economic conditions, such as increasing demand for deposit products when interest rates are high. For insurance, aligning campaigns with life events, like new home purchases or marriage, can maximize engagement. In Healthcare, advertisers are prioritizing personalized, regulation-compliant campaigns that address social determinants of health (SDOH). In Retail, advertisers are increasingly activating on both CTV and social platforms, with many managing their own in-house campaigns. While larger brands often rely on media agencies, a shift toward in-house media buying is emerging among some bigger players, offering more control over audience targeting and performance metrics. Our report covers each vertical’s unique menu, helping you select the right “ingredients” for your customers. With the top Experian Audiences on hand, you can create feasts that delight, nourish, and convert.

Every year, the Experian team attends the Consumer Electronics Show (CES) in Las Vegas to study the latest technological advancements and innovations that shape the AdTech industry. The energy at CES 2025 was palpable, with a whirlwind of conversations around artificial intelligence (AI), connected TV (CTV), privacy-first solutions, and sustainability in advertising. Here are four standout themes from this year’s event. 1. The AI evolution: More buzzwords, but growing potential AI dominated discussions this year, but the gap between hype and practical application was still evident. While some vendors showcased innovative tools for campaign optimization and audience creation, much of the buzz felt aspirational. The use of AI to generate audiences based on new types of data is a promising sign of things to come. Data providers, including those collaborating with Experian, are beginning to test AI tools to enhance audience accuracy and scale. The AI space still feels frenetic, but the potential for transformative change is undeniable. "AI was a hot topic, with discussions ranging from campaign optimization tools to audience selection. While many leaned on buzzwords, there were glimpses of legitimate use cases."Brooke Logan, VP of Data Strategy and Partnerships 2. CTV: A race for quality and curation CTV remained a popular topic at CES, particularly around the challenges of fragmentation and scale. Sellers are grappling with an oversupply of inventory, leading to a renewed focus on curation. Conversations highlighted the importance of premium audiences, brand safety, and identity resolution. In the fragmented CTV landscape, advertisers want to be able to define an audience once, have that audience be highly addressable, and then activate everywhere. One standout theme was the shift in CTV monetization strategies. With linear TV revenues declining, major publishers are exploring ways to maximize yields on streaming platforms. Direct-sold premium inventory still reigns, but programmatic is gaining traction—a trend we’re seeing driven by publishers seeking scalable solutions. "CTV remains fragmented. While premium inventory is largely direct-sold, big publishers are exploring ways to boost yield on streaming as linear revenue declines."Lauren Portell, Sr. Account Executive, Advanced TV 3. Privacy-first solutions The regulatory landscape continues to evolve, and advertisers are responding with innovative, privacy-centric methodologies. For industries like healthcare, privacy-first solutions are being developed from the ground up to comply with current and future regulations. The emphasis on cookieless and contextual advertising remains strong, with data providers utilizing first-party data to enrich audience targeting strategies. "Providers across verticals that are typically more sensitive are developing methodologies from the ground up based on current and future potential privacy regulations."Adam Kobus, Director of Data Partnerships 4. Eco-conscious advertising: Building a sustainable future Sustainability emerged as a growing focus, as indicated by initiatives like Scope3 and Experian’s own carbon reduction goals. Companies are exploring ways to reduce the environmental impact of ad serving and data management. For example, platforms like AdGood are transforming unused CTV inventory into opportunities for non-profit initiatives. While not strictly eco-focused, these efforts signal a shift toward more conscientious advertising practices. "Sustainability is gaining attention, with efforts to reduce the carbon footprint through eco-conscious advertising, data management practices, and ad serving."Erin Wolf, Sr. Account Executive, Demand Partnerships The buzz around Experian The launch of the Experian marketplace and the Audigent acquisition were major talking points, underscoring Experian’s commitment to innovation in AdTech. Together, Experian and Audigent will be an end-to-end solution where publishers big and small can empower marketers to better understand their customers, create precise audience segments, and activate those audiences across the best inventory. Likewise, Experian’s new data marketplace connects TV operators, programmers, supply partners, and demand platforms with top-tier third-party audiences across retail, CPG, health, B2B, and location intelligence. All audiences delivered from our marketplace benefit from our best-in-class offline and digital identity graphs, which ensure addressability across all channels like display, mobile, and CTV. An exciting year ahead CES 2025 underscored the rapid evolution of the advertising ecosystem. From AI to CTV and privacy-first solutions, the industry is adapting to new challenges and opportunities. As Experian continues to lean into these trends, our role in powering data-driven advertising through connectivity remains more focused than ever. We’re excited to see how these themes will evolve throughout the year and look forward to collaborating with our partners to shape the future of digital advertising.
