We’re excited to introduce the next segment in our Q&A series, Ask the Expert! Ask the Expert features a series of conversations with product experts where we dive into the areas you care most about like identity resolution, targeting, attribution, and more. Our next segment features a conversation about sell-side targeting.
Mike Chowla, SVP of Product at OpenX joins us to chat with Experian’s SVP of Sales & Partnerships, Chris Feo. OpenX is the world’s leading sell-side platform for audience, data, and identity targeting. In their conversation, Mike and Chris review:
- The shift to targeting on the sell-side
- How first- and third-party data are being used on the sell-side
- How OpenX is thinking about alternative IDs

What is sell-side targeting?
Sell-side targeting optimizes the way buyers and supply-side platforms (SSPs) work together. This approach moves the responsibility of inventory and audience targeting from the demand-side platform (DSP) into the SSP, providing advertisers with increased reach and better performance.
With sell-side targeting, locating your target audience becomes easier as you have a more direct connection with publishers. This increases your ability to scale against a target audience. Specifically, the SSP directly matches the buyer’s audience or data segment to the publisher inventory and audience and automatically sends the impression to the buyer’s DSP of choice via a deal ID, providing advertisers with improved reach and performance metrics as well as control over their inventory. With more direct access, your budget can likely go further, and you can decrease your effective cost per mille (eCPM) and get more working media.
“Supply-side targeting is the next phase of how supply path optimization (SPO) and buyers will need to work more closely with SSPs.” – Mike Chowla, SVP, Product, OpenX
Buying on the sell-side vs. open exchange
When buying on the open exchange, you have access to a vast number of impressions. With sell-side targeting, you can apply your campaign targeting directly on the supply-side and activate those impressions through a deal ID. Sell-side targeting works across various formats including web display, mobile, in-app, and connected TV (CTV) for a seamless advertising experience.
OpenX offers the unique capability to match users using their device graph within their SSP. This means you can target users from traditional data sources such as cookies or mobile ad IDs (MAIDs) and reach them in CTV or app environments. This gives you even more reach and precision in your advertising efforts.
The role of first- and third-party data on the sell-side
Buyers are showing a keen interest in bringing their own first-party data into the process of sell-side targeting. Meanwhile, certain agencies have been actively involved in working with identity and data. OpenX is currently collaborating with several agency ID solutions such as Choreograph, Merkel, and Horizon.
Buyers are also purchasing third-party data and data segments from various providers through OpenX’s platform for sell-side targeting purposes. By utilizing this data on the supply side, buyers are able to increase the match rate against their first- and third-party data segments in all environments. This ultimately maximizes scale against these audiences and drives a more efficient CPM due to eliminating waste.
Measurement and attribution on the sell-side
In the current state of SSP advertising, there is more of an emphasis on targeting capabilities than measurement and attribution. That said, SSPs can provide granular log level reports that can be utilized for multi-touch attribution (MTA) or mixed media models (MMM). These granular insights not only inform measurement and attribution models, but they also provide valuable optimization insights such as clearing price.
Additionally, advertisers have all of the same reporting options that they’re used to getting through their DSP because their buys are activated via deal ID in the DSP of their choice.
What to consider when transitioning to sell-side targeting
There are two primary items you should consider when transitioning to sell-side targeting:
- Supply
- Reach
Reach
Collaborating with partners who have the right capabilities can greatly improve reach and audience extension across different devices. For instance, if you bring your first-party audience or a third-party audience and are identifying that consumer via a cookie or MAID, being able to extend that targeting segment to other devices and platforms can be highly beneficial.
Supply
It’s crucial to collaborate with partners who have the right access to supply and direct connections with publishers. While targeting is essential, it’s equally important to have high-quality supply to drive performance.
Reaching consumers in a cookieless future
Whether you’re targeting on the demand or sell-side, it always starts with the consumer and who you’re trying to reach.
Significant changes in the consumer privacy landscape are impacting advertisers’ ability to access various signals emitted by consumers through their devices and browsers. Recent developments from Apple and Google have further amplified this situation.
Alternative IDs as a solution to signal loss
In response, we’re seeing the emergence of alternative IDs like UID2, Ramp ID, and ID5. OpenX supports these types of IDs and considers them crucial for audience buying in a privacy-centric cookie-less future.
We are still in the early stages of this evolution. While some of the IDs have good coverage, cookies will continue to be the primary targeting method as long as they remain available.
Nevertheless, we see alternative IDs as one of several solutions that will become increasingly important as third-party cookies disappear. Contextual buying will also emerge, and a set of solutions will come together to enable advertisers to keep finding their audience in a cookie-less world.
Overcoming signal loss with identity resolution
Looking ahead, as we continue to lose signals due to the evolving consumer privacy landscape, we will witness two things:
- Continued fragmentation
- A wide variety of identifiers
Content will continue to be available on various devices. We’re currently experiencing the emergence of connected TV, but who knows what other devices will surface over the next five to ten years. As cookies disappear, which have been the primary identifier, and alternative IDs are introduced, the wide variety of identifiers will create further fragmentation. This highlights the need for identity in the future.
Identity resolution at Experian matches fragmented identifiers to a single profile to create a unified, cross-channel view of your consumers. Our identity resolution solutions can help future-proof your marketing strategies.
How Experian and OpenX work together
Experian is a key player in OpenX’s OpenAudience solution and helps to power many of their data segments as well as their identity graph. While OpenX collaborates with a variety of providers and operates a fully interoperable platform, Experian remains valuable to the core technology within OpenX’s SSP.
“Experian powers a lot of the data segments and identity graph that OpenX has in our OpenAudience capabilities as part of our SSP.” – Mike Chowla, SVP, Product, OpenX

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.

Suppose you're watching your favorite TV show, and an ad suddenly catches your attention. It urges you to take immediate action, whether to call a number, visit a website, or text a keyword like ‘DETAILS’ to a specific number for more information. This is direct response television (DRTV), a powerful form of advertising available on all TV types — including live, cable, and streaming — that directly connects brands with consumers to drive immediate engagement and measurable results. The goal of DRTV marketing is simple: convert viewers into customers quickly and measurably by asking them to do something in real time. Every DRTV ad is carefully designed to drive quick conversions with a clear, direct path from interest to action. This makes it an essential tool for marketers who need to measure their return on investment (ROI) for TV and see instantaneous results. Key benefits of DRTV marketing Unlike traditional TV ads that build long-term brand awareness, DRTV campaigns are focused on driving instant results and are surprisingly effective at doing it. Here are a few benefits of DRTV and why it’s a powerful tool for marketers in a digitized world. Immediate customer engagement One of the biggest advantages of DRTV is its ability to engage customers right off the bat. DRTV grabs attention and motivates people to act now, whether with a phone number on the screen, a QR code to scan, or a limited-time offer, often with compelling incentives. Measurable ROI DRTV is designed to deliver precise, trackable results. Because the ads encourage specific actions — like visiting a website or calling a phone number — it’s easy to see what’s working and what’s not. Marketers can measure everything from sales to lead generation, which guides them in refining their strategies for even better results. Pairing DRTV with digital tools, like web analytics or CRM systems, can provide even deeper campaign performance insights. Broad reach Even in the streaming age, live TV and cable still attract millions of viewers, which makes DRTV excellent for brands needing to expand their reach. Marketers can even tailor DRTV ads to specific audiences by choosing the best time slots on the proper channels. Whether you’re targeting parents watching morning news or sports fans tuning into big games, you’ll know you’re connecting with the right people at optimal times. Types of DRTV ads DRTV advertising offers several formats, each suited to different audiences, budgets, and goals, whether you’re introducing a new product or driving traffic to your website. Infomercials Infomercials are the classic, long-form DRTV ads that most people associate with the term. These ads typically run for 15-30 minutes and go into detail on product benefits and features. They often include demonstrations and special offers to educate and engage viewers with urgent, limited-time deals. Think of the iconic “But wait, there’s more!” ads used to sell everyday items ranging from household cleaners to exercise equipment. Short-form ads Short-form DRTV ads are 30-second to 2-minute ads that get straight to the point with a single message or offer and a clear call-to-action (CTA) to encourage immediate engagement. Short-form ads are ideal for quick bursts of information, like promoting a flash sale or highlighting a new product. A 60-second ad showcasing a new mobile app might feature a quick walkthrough of its features, followed by a QR code or website URL to download it instantly. Product demos Some DRTV ads focus exclusively on demonstrating how a product works in real-life scenarios. These ads are great for showing off unique features or solving familiar pain points that make the product feel essential. A cookware brand might show how its nonstick pans make cooking and cleanup a breeze while including a CTA to “order now and get a free bonus spatula!” Testimonials Testimonials from real customers or experts are a great way to build trust and credibility. Hearing someone’s success story or endorsement of a product or service can help viewers feel confident about their purchase decision. A skincare brand, for example, might air a two-minute ad of a dermatologist explaining the science behind the product, along with five-star reviews from satisfied users. Call-in contests or limited-time offers This type of DRTV ad creates urgency by promoting a special offer or giveaway. Viewers might have to call a number or visit a website within a specific timeframe to claim the deal. For example, travel agencies sometimes air ads offering free vacations or planning kits to the first 100 callers, which helps them generate immediate leads. Hybrid ads with digital integration Many modern DRTV campaigns blend traditional TV with digital tools, like QR codes, social media hashtags, or links to custom landing pages. These hybrid ads meet viewers wherever they are. A fitness program might air a short-form ad with a QR code linking to their free app trial, making it easy for viewers to instantly engage. Success tips for DRTV advertising Creating a successful direct response TV campaign centers on messaging that resonates with the right audience, inspires action, and delivers measurable results. Here are some essential tips for a winning DRTV strategy. Strong CTA Every DRTV ad should include a compelling, straightforward CTA that motivates viewers to act immediately. Whatever it is, your CTA should be easy to understand and time-sensitive to create urgency, such as, “Claim this limited-time offer in the next 30 minutes!” Multi-channel integration Direct response TV works best when part of a broad multi-channel strategy, so you should make sure your campaign integrates well with digital channels. This can reinforce your message, help consumers engage across platforms, and drive better results. Audience targeting Precise audience targeting is critical to DRTV campaign success. Experian’s advanced TV audiences, developed with the Advertising Research Foundation (ARF), help you connect with the right viewers to drive immediate action. These syndicated audiences are now available on FreeWheel, the TV advertising industry’s global tech platform. With over 2,400 ready-to-use audience segments, Experian enables you to target specific groups, such as: TV viewership audiences: Target households based on viewing habits and preferred devices. In-market car buyers: Reach consumers actively searching for their next vehicle, which is ideal for driving sales. Holiday shoppers: Engage gift-givers, deal-seekers, and travelers during peak shopping seasons. New TV audiences released in August 2024 In addition to these, our August 2024 release introduced several updates that further refine Experian’s targeting capabilities. Some of the audience updates in this release included: New retail transaction audiences: These segments offer insights into categories like children’s products, parenting, hobbies and crafts, science and nature, and sports and fitness. With high spending and frequent purchase behaviors, these audiences provide a deeper understanding of consumer preferences. Notable segments include: Sports and fitness high spenders Children’s product high spenders Science and nature high spenders Updated TV audiences: New and refreshed TV segments now reflect the viewing habits of today’s consumers for accurate insights and targeting. Examples of newly added segments include: Free and paid ad-supported streaming TV subscribers Satellite service subscribers Cable and streaming TV service subscribers With these advanced targeting capabilities, your DRTV campaigns can be more effective and resonant with viewers most likely to respond for maximum ROI and engagement. Effective planning A strong DRTV campaign starts with defining your objectives, budgeting effectively, and identifying the right media mix. Understanding where your audience spends their time — prime-time TV or niche cable channels — will get you the most value from your DRTV investment. Real-time tracking Tracking your DRTV campaign’s performance in real time is critical for success. Tools that provide immediate insights into viewer responses, website visits, or call volumes allow you to identify what’s working and pivot quickly if needed. Measuring success Measuring success against key performance indicators (KPIs) like conversion rates, ROI, or cost-per-acquisition (CPA) is an excellent way to know if your DRTV campaign is delivering results. Experian’s advanced data solutions make tracking and analyzing campaign performance easier, so you can make data-informed decisions and deliver precise results to stakeholders. Continuous optimization DRTV marketing is an ongoing effort. Use the insights from real-time tracking and performance measurement to refine your strategy. Optimization keeps your campaign relevant and effective, whether you need to tweak your CTA, adjust your audience targeting, or test new creative formats. How DRTV relates to advanced TV and connected TV While DRTV has historically focused on immediate viewer actions via traditional linear TV, it’s found new relevance within advanced TV and connected TV (CTV) ecosystems. These modern formats expand the measurable, action-driven qualities of DRTV while incorporating the precise targeting and personalized storytelling made possible by digital technologies. DRTV and advanced TV Advanced TV enhances DRTV by enabling addressable advertising, which helps marketers deliver ads to specific households based on behavioral or demographic data. For instance, using tools like Experian’s Graph, advertisers can integrate data sets across multiple sources to refine audience segmentation and tailor messages to individual households. Advanced TV also supports cross-channel consistency to provide a unified customer experience whether the viewer engages with linear TV, streaming services, or other devices. Additionally, programmatic ad buying plays a role in automating the ad-buying process. This helps advertisers optimize their bids and placements and get DRTV campaigns in front of the right audience at the right time, which maximizes cost-efficiency across both traditional and digital channels. DRTV and CTV CTV has a high rate of logged-in, authenticated viewers and provides a lot of helpful first-party data. This allows for hyper-precise audience targeting, cross-device attribution, and an ability to link ad exposure to conversions — even when purchases occur on non-CTV devices. Universal IDs like UID2 further strengthen these capabilities by creating consistent and privacy-respecting user identities across platforms. Experian’s TV partnerships Through partnerships with leading CTV players like Madhive, Samsung, Disney/Hulu, and others, Experian’s identity solutions integrate seamlessly to support well-timed, personalized ads across major streaming platforms. These integrations, powered by our Digital and Offline Graphs, offer a complete view of audiences to enable more controlled, effective activation across mediums, including free ad-supported streaming television (FAST) channels. Using Experian’s advanced data and identity tools, advertisers can tap into the full potential of DRTV strategies within advanced TV and CTV to make campaigns more actionable, efficient, and impactful. The future of DRTV So, what is DRTV going to look like in the future? With the integration of digital and television platforms, DRTV is becoming more targeted, interactive, and personalized. This shift creates new opportunities for advertisers to drive conversions. Here are some key advancements that will continue to shape the future of DRTV: Addressable TV: Advertisers can deliver targeted ads to specific households based on demographic and behavioral data. It uses data from smart TVs, streaming devices, and third-party data providers to enable highly relevant ads based on the interests of individual viewers. Interactive TV ads: Interactive TV ads enable viewers to engage directly with the content through their remote control or mobile devices. Users can click on a product for more information or make purchases without leaving the TV screen and immediately convert. Authenticated audiences: With CTV and AI technology, advertisers can use first-party data from authenticated users to improve targeting, measurement, and campaign performance. Advertisers can create a more cohesive and personalized experience by linking viewers across multiple devices, which improves ad effectiveness and attribution. Branded apps with saved information: Branded apps that store payment and personal information streamline the direct response process. These apps reduce purchase journey friction and allow quicker conversions, as viewers can complete transactions with fewer steps. QR codes replacing URLs: QR codes are becoming a popular alternative to traditional URLs in DRTV ads. These codes provide a quick, convenient way for viewers to visit a website, access a product page, or act on a CTA simply by scanning the code with their phone. Better targeting algorithms: Advancements in targeting algorithms allow advertisers to serve more personalized and relevant ads. These algorithms help ads reach the right audience at the right time, which can increase engagement and conversion rates. These innovations offer advertisers more tools to connect with audiences in a personalized, interactive, and measurable way.
