2024 marked a significant year. AI became integral to our workflows, commerce and retail media networks soared, and Google did not deprecate cookies. Amidst these changes, ID bridging emerged as a hot topic, raising questions around identity reliability and transparency, which necessitated industry-wide standards. We believe the latest IAB OpenRTB specifications, produced in conjunction with supply and demand-side partners, set up the advertising industry for more transparent and effective practices.
So, what exactly is ID bridging?
As signals, like third-party cookies, fade, ID bridging emerged as a way for the supply-side to offer addressability to the demand-side. ID bridging is the supply-side practice of connecting the dots between available signals, that were generated in a way that is not the expected default behavior, to understand a user’s identity and communicate it to prospective buyers. It enables the supply-side to extend user identification beyond the scope of one browser or device.
Imagine you visit a popular sports website on your laptop using Chrome. Later, you use the same device to visit the same sports website, but this time, on Safari. By using identity resolution tools, a supply-side partner can infer that both visits are likely from the same user and communicate with them as such.
ID bridging is not inherently a bad thing. However, the practice has sparked debate, as buyers want full transparency into the use of a deterministic identifier versus an inferred one. This complicates measurement and frequency capping for the demand-side. Before OpenRTB 2.6, ID bridging led to misattribution as the demand-side could not attribute ad exposures, which had been served to a bridged ID, to a conversion, which had an ID different from the ad exposure.
OpenRTB 2.6 sets us up for a more transparent future
In 2010, the IAB, along with supply and demand-side partners, formed a consortium known as the Real-Time Bidding Project for companies interested in an open protocol for the automated trading of digital media. The OpenRTB specifications they produced became that protocol, adapting with the evolution of the industry.
The latest evolution, OpenRTB 2.6, sets out standards that strive to ensure transparency in real-time bidding, mandating how the supply-side should use certain fields to more transparently provide data when inferring users’ identities.
What’s new in OpenRTB 2.6?
Here are the technical specifications for the industry to be more transparent when inferring users’ identities:
- Primary ID field: This existing field now can only contain the “buyeruid,” an identifier mutually recognized and agreed upon by both buyer and seller for a given environment. For web environments, the default is a cookie ID, while for app activity, it is a mobile advertising ID (MAID), passed directly from an application downloaded on a device. This approach ensures demand-side partners understand the ID’s source.
- Enhanced identifier (EID) field: The EID field, designated for alternative IDs, now accommodates all other IDs. The EID field now has additional parameters that provide buyers transparency into how the ID was created and sourced, which you can see in the visual below:
Using the above framework, a publisher who wants to send a cross-environment identifier that likely belongs to the same user would declare the ID as “mm=5,” while listing the potential third-party identity resolution partner under the “matcher” field, which the visual below depicts. This additional metadata gives the demand-side the insights they need to evaluate the reliability of each ID.
“These updates to OpenRTB add essential clarity about where user and device IDs come from, helping buyers see exactly how an ID was created and who put it into the bidstream. It’s a big step toward greater transparency and trust in the ecosystem. We’re excited to see companies already adopting these updates and can’t wait to see the industry fully embrace them by 2025.”
Hillary Slattery, Sr. Director, Programmatic, Product Management, IAB Tech Lab
Experian will continue supporting transparency
As authenticated signals decrease due to cookie deprecation and other consumer privacy measures, we will continue to see a rise in inferred identifiers. Experian’s industry-leading Digital Graph has long supported both authenticated and inferred identifiers, providing the ecosystem with connections that are accurate, scalable, and addressable. Experian will continue to support the industry with its identity resolution products and is supportive of the IAB’s efforts to bring transparency to the industry around the usage of identity signals.
Supply and demand-side benefits of adopting the new parameters in OpenRTB 2.6
- Partner collaboration: Clarity between what can be in the Primary ID field versus the EID field provides clear standards and transparency between buyers and sellers.
- Identity resolution: The supply side has an industry-approved way to bring in inferred IDs while the demand side can evaluate these IDs, expanding addressability.
- Reducing risk: With accurate metadata available in the EID field, demand-side partners can evaluate who is doing the match and make informed decisions on whether they want to act on that ID.
Next steps for the supply and demand-sides to consider
For supply-side and demand-side partners looking to utilize OpenRTB 2.6 to its full potential, here are some recommended steps:
For the supply-side:
- Follow IAB Specs and provide feedback: Ensure you understand and are following transparent practices. Ask questions on how to correctly implement the specifications.
- Vet identity partners: Choose partners who deliver the most trusted and accurate identifiers in the market.
- Be proactive: Have conversations with your partners to discuss how you plan to follow the latest specs, which identity partners you work with, and explain how you plan to provide additional signals to help buyers make better decisions.
We are beginning to see SSPs adopt this new protocol, including Sonobi and Yieldmo.
“The OpenRTB 2.6 specifications are a critical step forward in ensuring transparency and trust in programmatic advertising. By aligning with these standards, we empower our partners with the tools needed to navigate a cookieless future and drive measurable results.”
Michael Connolly, CEO, Sonobi
These additions to the OpenRTB protocol further imbue bidding transactions with transparency which will foster greater trust between partners. Moreover, the data now available is not only actionable, but auditable should a problem arise. Buyers can choose, or not, to trust an identifier based on the inserter, the provider and the method used to derive the ID. While debates within the IAB Tech Lab were spirited at times, they ultimately drove a collaborative process that shaped a solution designed to work effectively across the ecosystem.”
Mark McEachran, SVP of Product Management, Yieldmo
For the demand side:
- Evaluation: Use the EID metadata to assess all the IDs in the EID field, looking closely at the identity vendors’ reliability. Select partners who meet high standards of data clarity and accuracy.
- Collaboration: Establish open communication with supply-side partners and tech partners to ensure they follow the best practices in line with OpenRTB 2.6 guidelines and that there’s a shared understanding of the mutually agreed upon identifiers.
- Provide feedback: As OpenRTB 2.6 adoption grows, consistent feedback from demand-side partners will help the IAB refine these standards.
Moving forward with reliable data and data transparency
As the AdTech industry moves toward a cookieless reality, OpenRTB 2.6 signifies a substantial step toward a sustainable, transparent programmatic ecosystem. With proactive adoption by supply- and demand-side partners, the future of programmatic advertising will be driven by trust and transparency.
Experian, our partners, and our clients know the benefits of our Digital Graph and its support of both authenticated and inferred signals. We believe that if the supply-side abides by the OpenRTB 2.6 specifications and the demand-side uses and analyzes this data, the programmatic exchange will operate more fairly and deliver more reach.

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.
