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.

As technology reshapes our media experience, TV remains a powerful channel for content consumption. In our next Ask the Expert series, we dive into a pivotal subject – the convergence of TV, linear (conventional broadcast and cable TV), and digital marketplaces. In this Q&A segment, we’re joined by two industry experts, Dan Hickox, VP of Development & Partnerships at 605, an iSpot.tv Company, and Chris Feo, Experian’s SVP of Sales & Partnerships, who guide us through an engaging discussion on convergent TV, attribution, measurement, and safeguarding personal data in the evolving landscape of TV advertising. How convergent TV is changing the future of advertising The convergence of traditional TV and digital streaming platforms presents an innovative opportunity for advertisers to engage their target audience. With convergent TV, you can create campaigns that bridge the gap between linear and streaming, ensuring your message reaches your target audience while avoiding ad fatigue. Along with high-quality content, extensive inventory, and targeting capabilities, convergent TV offers advanced measurement and attribution tools that will empower you to optimize advertising campaigns for maximum impact. You can make better decisions regarding when and where to strategically allocate your advertising budgets with effective TV measurement and attribution. Attribution in converged TV TV attribution involves tracing consumer actions and uncovering valuable insights into their behavior. With these insights, you can gain a clear understanding of the audience exposed to your ads and their actions in response. Lean into data attribution tools to track your target audience throughout the customer buying journey. Measurement in converged TV In contrast, TV measurement enables the tracking of performance TV advertising campaigns to assess campaign effectiveness. Through converged TV measurement solutions, you can rely on a singular data source, unifying different channels, devices, and metrics for actionable insights. This analysis will give you insights into the audience reached, their location, and the resulting actions taken. TV attribution’s impact on cross-channel media Embracing an omnichannel advertising approach is vital. Evaluating advertising campaigns across various platforms and devices – including linear, TV, and digital channels – is essential for identifying the channels that drive revenue for your businesses. Converged TV and digital streaming enable you to control ad frequency across all channels, enhancing the cross-screen experience. This convergence paves the way for a more comprehensive and holistic future in advertising. Here are three ways TV attribution impacts cross-channel media. Identify the most effective channels TV attribution offers a significant advantage in determining the channels that generate the most conversions. By using this data, you can make informed choices about budget allocation to achieve maximum impact. Deliver a seamless customer experience Consumers demand consistency in their brand interactions. TV attribution can help you by guiding the optimal timing and placement of ads, resulting in a more seamless viewing experience. This synchronization can significantly enhance customer loyalty and retention. Enhance marketing effectiveness By identifying the most effective channels and refining campaign strategies, TV attribution can significantly improve the success of marketing campaigns. The outcome is a measurable increase in sales and revenue, demonstrating the impact of informed and data-driven advertising. Audience-based targeting across linear and digital ecosystems It's crucial to comprehend and connect with the appropriate audience. The emergence of linear and digital platforms has required the development of audience targeting. Across these two ecosystems, audience-based targeting aims to enhance this process by concentrating on specific audience segments rather than general demographics or programming. Benefits of audience-based targeting There are four key benefits of audience-based targeting across the TV ecosystem. Personalization at scale Digital platforms have conditioned users to expect tailored experiences. Audience-based targeting ensures ads resonate with individual preferences and behaviors, even within the vastness of linear TV. Combining data from both linear and digital sources makes it possible to segment audiences more precisely. This results in advertising content tailored to each individual, making it more relevant and personalized. Optimized ad spend Improve your return on investment by targeting specific audience segments more likely to convert, ensuring your messages reach suitable viewers. In contrast to traditional TV purchasing, where advertisement slots are bought based on a show's overall demographic, audience-based targeting focuses on the viewers' behavior and interests, regardless of the program they are watching. Unified measurement and analytics When combining traditional and digital methods of reaching target audiences, it is essential to have a consistent approach to measuring success. By doing this, you can gain insight into how well your ad campaigns perform across different platforms and the frequency with which they are being seen. By comprehensively understanding audiences within different ecosystems, you can adjust your strategies in real time, guaranteeing that your campaigns remain flexible and successful. Enhancing the viewer experience Audience-based targeting benefits viewers by reducing the number of irrelevant ads they see. As a result, viewers can have a more pleasant experience while watching content, which may discourage them from skipping ads and increase their engagement with the content. Future-proofing and safeguarding data Businesses are focusing on future-proofing for data privacy, and safeguarding individual data is becoming more significant than ever before. Now’s the time to embrace new methods that protect your data privacy while ensuring that measurement remains accurate. Experian offers privacy-safe solutions to help businesses preserve precise measurement, even with fewer cookies. "What we're working toward is future-proofing ourselves. To do that, we work with partners like Experian who are already thinking forward, and with your pixel technology, we can capture and resolve the identifiers that we know will be around for a while."Dan Hickox, VP, Solutions Consulting, Development & Partnerships, 605 How Experian and 605 work together 605 is an independent TV measurement and analytics company providing solutions for advertising, content measurement, attribution, planning, optimization, and media transactions. “We partner with great identity partners, such as Experian, that really help us act as the connecting glue across different data touch points.

Over the last few months, Experian has released new syndicated audiences to most major platforms supporting retail and travel. In this blog post, we’ll highlight some of these new audiences and how they can be used with other data from Experian to build the perfect audience to reach your customers and prospects. What separates Experian's syndicated audiences Experian’s 2,400+ syndicated audiences are available directly on over 30 leading television, social, programmatic advertising platforms, and directly within Audigent for activation within private marketplaces (PMPs). Reach consumers based on who they are, where they live, and their household makeup. Experian ranked #1 in accuracy by Truthset for key demographic attributes. Access to unique audiences through Experian’s Partner Audiences available on Experian’s data marketplace, within Audigent for activation in PMPs and directly on platforms like DirectTV, Dish, Magnite, OpenAP, and The Trade Desk. Household Expenditure audiences We’ve created new predictive audiences to help retailers reach consumers across 35 categories likely to spend within that category. A few categories include Apparel, DIY, Health, and more. With the launch of these new audiences, we will retire our existing Household Consumer Expenditure, Online and Retail category audiences in the November Digital Master update. Who these audiences are for Our Household Expenditure audiences use data from multiple sources, providing brands with highly accurate purchase predictions and data that scales for digital execution. Household Expenditure audiences are an excellent solution for brands with new product lines or where targeting based on historical purchases lack signal brands seek. Building data from multiple data sources helps ensure high performance and accuracy and can illuminate trends in consumer shopping patterns. These trends can be used to help predict future shopping behaviors. How to refine our Household Expenditure audiences To refine your audience, you can combine this data with Experian’s demographic and household expenditure audiences to ensure you are reaching consumers. For example, suppose you’re an apparel brand launching a new line aimed toward women over the age of 40. In that case, you can use Experian’s demographic data to reach those women and layer in our household expenditure purchase predictor segment for women's apparel to reach their new target audience. Mobile Location audiences We’ve expanded our location database to include more locations and points of interest. With this new data, we could strengthen our existing mobile location audiences to broaden the reach, improve accuracy, and increase performance. We’ve created 11 new mobile location audiences with our new dataset that supports the retail and travel verticals. These new audiences include new shopping behaviors, including high-income and high-end shoppers and travel and entertainment behaviors, including visiting sporting arenas like MLB, NBA, NFL, and university stadiums. Who these audiences are for These audiences are for brands that want to reach consumers based on their location behaviors. Often valid for retail, travel, and entertainment brands, Mobile Location audiences provide brands with highly accurate data that shows previous intent and interest in critical locations. How to refine our Mobile Location audiences To refine your audience, you can combine your Mobile Location audience with Lifestyle and Interest data. For example, if you are creating an advertising campaign for a hotel near a university stadium for the largest game in the season, you could combine university stadium visitors with sports enthusiasts and in-market for travel to find consumers most likely to be interested in your campaign and staying at the hotel. Purchase-Based Transaction audiences For use cases where predictive audiences aren’t the best fit to reach the right consumer, such as targeting consumer’s historical purchases, we’ve created new purchase-based transaction audiences that utilize opt-in consumer transaction data across 29 retail categories, including apparel, home, lifestyle, health, food and beverage, and more. Who these audiences are for These audiences are a perfect fit for brands trying to reach consumers based on previous purchases. These audiences can be broken out by their spending patterns – frequency of purchase and high spenders – and their response to advertising, including direct mail, email, inserts, and digital. How to refine our Purchase-Based Transaction audiences Combine these new audiences with Mosaic to fine-tune your audience based on their purchasing and lifestyle patterns. Suppose you are a brand with a new line of home décor products launching and will utilize influencers to endorse your product line. In that case, you can use Experian’s purchase-based transaction audiences for high spenders in home décor and layer our Mosaic audience Influenced by Influencers to find consumers who are most likely to purchase and trust an influencer. We can help you discover and activate your perfect audience Our audiences are available in most major data and execution platforms. Visit our partner page for more information. Don’t see our audiences on your platform of choice? We can help you build and activate an Experian audience on the platform of your choice. Contact us Latest posts

The AdTech industry is buzzing with discussions about cookie deprecation and effective strategies to tackle it. One of the commonly suggested solutions is the utilization of clean rooms alongside responsibly sourced first-party data. Above all else, the industry recognizes the importance of respecting consumer data and complying with all privacy laws. Additionally, the industry acknowledges the need for a change in our historical practices. This shift benefits everyone involved, as consumer data is more secure than ever. Tremendous investments have been made to ensure the utmost security of consumer information. Clean rooms are one of the tools that enable companies to use data securely, ensuring the content that you see is as relevant as possible. Two ways the AdTech industry is addressing cookie deprecation The days of sending data directly to partners for usage or for using only third-party data for marketing efforts are gone. Now, the emphasis is on responsibly collecting first-party data and using clean rooms to enrich first-party data to enhance marketing efforts. First-party data The industry is starting to lean into first-party data gained through transparent means. This valuable information provides organizations with deeper insights into their customers, allowing for more personalized and effective interactions. By embracing the power of first-party data, either on its own or enriched via partner collaboration, you can cultivate stronger relationships, build trust, and deliver tailored experiences that resonate with your customers on a deeper level. Clean rooms Many data lakes and warehouses offer this service, ensuring their clients can not only store their data with them but can connect it with other partners in a secure environment and extract more information through the combined data sets versus their data on its own. Brands and their partners recognize that they need to work together, and a clean room provides a secure environment to share their first-party data without exposing their sensitive data to their partner. So, while we're losing third-party cookies, brands and partners can still get value from first-party data by using a clean room to generate audience insights, segmentation strategies, personalized experiences and offers, media plans, and measurement and attribution. Three ways data clean rooms can improve Data clean rooms are a great way to facilitate data collaboration while ensuring sensitive data is not exposed. Data clean rooms are not yet easy to use nor are they inexpensive. They require investment, both financially and resource allocation-wise, and you are not guaranteed to yield great match results. Let’s dive into three areas for data clean room improvement. High cost According to the IAB's State of Data 2023, nearly two-thirds of data clean room users spent at least $200K on the technology in 2022. In addition, one-third of data clean room users expect the price of data clean rooms to rise in 2023. The high cost of this solution can make it inaccessible to smaller companies in the advertising space. Resource intensive Nearly half of the companies using data clean rooms have a team of six or more dedicated to the technology, according to the IAB’s State of Data 2023, while nearly a third of companies using data clean rooms have 11 or more employees focused on the technology. Data clean rooms are not turnkey solutions. Inefficient matching Even if companies are using clean rooms does not mean that they are automatically going to achieve great success. Identity fragmentation, data hygiene, and differing identifiers can suppress client match rates in clean rooms, leading to significant investment and a lackluster output. How to get the most return on your clean room investment The finish line for data collaboration in clean rooms is not just having a relationship with a clean room. Instead, you should incorporate an identity resolution solution in your clean room. By adding an identity solution to your clean room, you can: Resolve and match all your identity data, regardless of the identity data that you or your partner have, giving you a larger data foundation to analyze. Generate more valuable insights and information, leading to a better experience for your customers. Join data sets to create smarter activation and targeting strategies and produce more holistic measurement. Experian can help you get started with identity resolution and data clean rooms If you are investing in data clean rooms, that means you are committed to the best in data practices. Experian recommends going the extra step and that you also invest in finding an identity resolution solution. By doing this, you can see better match rates. Experian offers this capability and has existing relationships with three clean room partners, Amazon Web Services, InfoSum, and Snowflake. In addition to collaborating in clean rooms, we offer collaboration in two other secure environments. Contact us today to discuss how we enable identity resolution in clean rooms or to chat about our other collaboration capabilities. Get in touch Latest posts
