First-party data creates value when marketers activate it. In 2026, leading brands will move beyond data collection by connecting, enriching, and activating their first-party data across channels. With identity as the foundation, first-party data activation improves relevance, efficiency, and measurement. Experian helps marketers turn static records into scalable audiences that perform across media.Why does activation expand the value of first-party data?
First-party data already delivers value through insight, personalization, and owned-channel engagement. In 2026, marketers expand that value by activating first-party data across owned and paid media channels. Activation is how existing data investments scale beyond CRM into broader audience strategies.
Simply capturing customer data used to feel like a win. Building a CRM, capturing emails, and logging transactions delivered valuable insights and fueled owned channels like email and direct mail. But that was largely where activation stopped.
In 2026, that mindset is no longer enough. Owning first-party data is now just the starting point. The real advantage comes from what marketers do next. Safely turning static records into addressable, scalable audiences is where first-party data can continue to prove its value.
How are marketers shifting from data collection to data connection?
As signals fragment, marketers are shifting from data collection to data connection to make first-party data usable across channels. Experian supports this shift by helping marketers onboard and resolve their data into a clean, connected foundation using our identity graphs. Connecting offline and online interactions allows brands to unify customer data across touchpoints to make it actionable. That connection enables more use cases, from audience activation and measurement to personalization and cross-channel optimization.
Most brands recognize the value of their own data. Fewer have the infrastructure to make it work across the media ecosystem. Data often sits in silos, disconnected from activation platforms, analytics, and measurement. Without the ability to unify, enrich, and deploy that data, first-party data remains underutilized.
In 2026, leading marketers are closing that gap by turning first-party data into audiences they can reach across owned and paid channels, bringing consistency to targeting and measurement. That same connectivity also enables better suppression, allowing brands to avoid targeting existing customers in prospecting campaigns. For consumers, this reduces irrelevant and repetitive ads. For marketers, it improves efficiency and protects the customer experience.
With Experian’s identity foundation in place, first-party data becomes usable across the media ecosystem. Marketers can enrich their first-party data with behavioral, demographic, and lifestyle insights, combined with trusted partner data, and activated across channels like social, programmatic, and TV, from a single environment.
Why is first-party data becoming central to media planning?
First-party data has become central to media planning because it gives marketers control, consistency, and continuity across channels. As media environments fragment, first-party data provides a stable signal that supports activation, personalization, and measurement at scale.
Rather than relying on any single data source, marketers are increasingly combining their own first-party data with trusted third-party and partner data to extend reach, improve relevance, and fill gaps in their own insights. Doing so effectively requires deterministic matching, privacy-first infrastructure, and partners that can support both owned and syndicated data at scale.
This approach allows brands to maintain control over their customer relationships while continuing to utilize third-party data for prospecting, modeling, and performance optimization across channels. As a result, first-party data activation is now central to how media strategies are planned and executed.
2026 Digital trends and predictions report
Our 2026 Digital trends and predictions report is available now and reveals five trends that will define 2026. From curation becoming the standard in programmatic to AI moving from hype to implementation, each trend reflects a shift toward more connected, data-driven marketing. The interplay between them will define how marketers will lead in 2026.
What business impact does first-party data activation deliver?
First-party data activation delivers measurable business impact, including:
- 70% of B2B marketers plan to increase their use of first-party data, more than any other data strategy.
- 67% percent of brands and 80% of publishers expect to grow their first-party data sets in the next year.
- The payoff is tangible. Activating first-party data can reduce customer acquisition costs by up to 50% and drive a 10-15% lift in revenue.
Activation drives efficiency. Brands that put their own data to work see lower acquisition costs and stronger revenue lift. These gains come from relevance. When marketers activate audiences built from known customer relationships, they reduce waste and optimize toward outcomes that matter.
Experian’s Audience Engine supports this model at scale. Audience Engine helps marketers onboard and activate first-party data through a single unified platform. It connects more than 3,500 syndicated audiences, over 50 media platforms, and 20+ third-party data providers. Marketers can combine, gain insights from, and deploy first-party data quickly.
What should marketers plan for first-party data activation in 2026?
In 2026, marketers should plan for first-party data to operate across onboarding, activation, and measurement as a connected workflow. Planning now centers on interoperability, scalable activation tools, and privacy-forward enrichment rather than isolated data use cases. Identity underpins each of these three shifts.
Why first-party data activation matters to marketers in 2026
In 2026, first-party data delivers value when marketers activate it across channels. The opportunity is to extend the value of what already exists through activation, enrichment, and identity-led connection across channels. That means uncovering insights within your existing customer base, building lookalikes from your highest-value audiences, and activating those segments across every channel.
With Experian’s Audience Engine, marketers can onboard, enrich, and activate their first-party data in one secure, interoperable platform. Identity connects to outcomes. Performance becomes measurable. Privacy stays at the core.

Everyone knows that it’s important for businesses to have a clearly defined brand. In the modern world, the personal brand has become just as important, and many professionals are trying to build up their public reputation, expertise and industry authority. In the digital age, there are many different methods and channels you can use to build your personal brand, but some are more efficient than others. According to Forbes Agency Council, here are some of the most effective ways to develop an authentic personal brand.1. Give More Than You Receive Whatever you do, always aim at giving more than you receive. When you build your network, try to bring value to each new person that you meet. When you get featured in some media, see what you can do for them in return. This is the best strategy because actions speak louder than words. People will remember you for what you are, not what your website is. - Solomon Thimothy, OneIMS 2. Define What You Stand For, Then Align Your Actions Define your mission. What is your purpose? What do you want to accomplish, and what is your key message? Once you have answers to those questions, use that mission as a guiding North Star to consistently reinforce your personal brand every day. This will come across in how you lead, how you interact with employees and peers, how you communicate, and how you give back to the community. - Preethy Vaidyanathan, Tapad 3. Develop A Creative Positioning Statement It’s all about positioning your company. You need to have creative positioning statements about who you are and what your company is doing to benefit its clients. Clients want resolutions to their problems, and that’s where you come to the rescue. It’s either sold or ignored. - Cagan Sean Yuksel, GRAFX CO. 4. Speak At An Event Becoming a keynote speaker gives you access to the things you need to elevate your brand: influencer status, large audiences and media profile. But access doesn’t equal attention. While speaking gives you the platform, you need to have something compelling to say. You’ll need a differentiated message, unique presentation style and a great agent to make this strategy successful. - Andrew Au, Intercept Group 5. Focus On A Specific Audience The most effective way to build your personal brand is to create content specifically for a very specific group of people. Create relevant content that details solutions to the unique needs of this audience so that it spreads quickly due to its hyper-relevance. This creates authority and credibility for your personal brand and helps you stand out as being the most relevant expert in your field. - Adam Guild, Placepull 6. Be Ruthlessly Consistent Developing a personal brand requires ruthless consistency in your subject matter and how you present yourself to the world. I go back to the early days of marketing blogs. In those days, some bloggers were all over the map with content. The ones who were consistent with their audience and their goals are the ones who had staying power. They became the authors, speakers and consultants. - Scott Baradell, Idea Grove 7. Follow Through Just like a traditional brand, the quality of your offering helps to build your brand. If you are clear on what you can and cannot deliver and always follow through on your word, your personal brand reputation will precede you and will be lifted by the recommendations of others. - Kieley Taylor, GroupM 8. Build A Solid Reputation “Personal brand” is just a new-age name for reputation. Doing your job exceptionally well, going above and beyond, treating people with respect and kindness, having a point of view—essentially any action that builds a solid professional reputation does the very same for your personal brand. - Jess Cook, TMV Group 9. Define Your Voice Establish your unique voice and personal point of view and stick to it in all you do and all you say. Personal brands must be consistent and have consistency in messaging, attitude and behavior. Express your personal brand through comments on articles, at significant events and important platforms where it can best showcase and support your personal point of view and brand persona. - Pat Fiore, FIORE 10. Create And Share Video Content Video is hard for many people. That’s why it can be your competitive advantage if you do it. Video allows you to be seen, heard and felt emotionally in a way that no other medium can. You may say, “That’s not for me” and that’s fine, but good luck competing with those who embrace it. Barriers to video are so low that building a personal brand without it seems as if you are hiding something. - A. Lee Judge, Content Monsta 11. Share Your Point of View In Everything You Do There are a finite number of topics that make for interesting discussion in our industry, so having a point of view and sharing it through crafted content is vital for building your personal brand. You don’t have to be controversial, necessarily, but considering themes and topics and providing honest commentary that demonstrates experience is the quickest way to build your reputation. - David Harrison, EVINS 12. Stay True To You The most effective way to build your personal brand is to be true to who you are. If you are wildly creative and outgoing, show that in your branding! Don’t hold back in your content; post that crazy Instagram picture that shows the world how you think. If you are conservative, then own that. This passion for who you really are—and what your company really is—authentically shines through. - Katy Boos, Remix Marketing Inc. Contact us today
OpenAudience™ will provide marketers the ability to easily plan and buy advertising for every digitally addressable consumer across the open web LOS ANGELES, May 2, 2019 /PRNewswire/ — For the past decade, the most effective way to advertise in digital media has been on Facebook and Google. Marketers in the U.S. now spend two-thirds of all digital ad spend on the "walled gardens", despite the fact that they receive less than 36 percent of total consumer time spent online. According to eMarketer, addressing this massive asymmetry in advertising – where tens of billions of dollars are over allocated to the walled gardens – is the top concern of marketers in 2019. While programmatic technology has become the primary monetization system for the open web, it has lacked the simplicity and efficacy of walled gardens. Today, OpenX is changing that paradigm by bringing true people-based marketing to the open web for the first time with the introduction of OpenAudience. OpenAudience will provide marketers and publishers with an unprecedented, unified level of knowledge about consumer audiences – through a platform built on privacy by design principles that brings the efficiency and efficacy of walled garden advertising to the open web. OpenAudience is powered by a comprehensive proprietary data asset and supplemented by integrated partnerships with recognized leaders in data and identity like LiveRamp, Tapad, a part of Experian, and more. For marketers, OpenAudience will provide the ability to plan and buy people-based marketing campaigns that combine the impact and ease of use of Facebook advertising with the scale of the open web. OpenAudience is currently in active partner testing with multiple marketers in the U.S., including Fortune 500 financial service and consumer personal care companies, along with one of America's largest online entertainment outlets, and will be generally available to the broader market in Q3 of 2019. For publishers, OpenAudience will deliver user-based knowledge that empowers them to value and sell advertising with unparalleled precision. With the ability to automatically place consumers into high-value audience segments drawn from the more than 240M U.S. Monthly Active Users OpenX reaches across the open web, OpenAudience allows publishers to maximize revenue like never before. "OpenAudience is a natural evolution of programmatic advertising, combining the unified knowledge of people-based audiences with the transactional power of programmatic to create a planning, buying and advertising experience that is unlike anything else in the market today," said Todd Parsons, chief product officer at OpenX. "No exchange in the market today has enabled a unified view of publisher audiences," said Travis Clinger, vice president of strategic initiatives, LiveRamp. "Now, OpenX is democratizing identity across all publishers on the open web, helping marketers to plan and buy audiences the way they do inside walled gardens. We are thrilled to be a key component of OpenAudience." "OpenAudience is an ambitious move into people-based marketing, offering marketers an unprecedented walled garden-like experience on the open web," said Chris Feo, senior vice president of global data licensing and strategic partnerships at Tapad. "As a fellow pioneer in the industry, Tapad is proud that OpenX chose to leverage The Tapad Graph™ to allow marketers and publishers in North America access to our leading digital identity resolution insights across devices."

Tom Rolph, VP EMEA at Tapad, part of Experian, says that ad-sponsored streaming services can be successful if they can deliver a higher quality viewer experience than other streaming services. Last week, Hulu, the streaming service acquired by Fox and now owned 60 per cent by Disney, announced it will be regularising its ad loads. The streaming service will be bringing ad breaks down to 90 seconds in an effort to deliver a better viewer experience. This is a positive move from Hulu and one which other ad-supported streaming services should follow in order to be successful in a competitive market. Previously ad breaks on Hulu could vary wildly, from 180 seconds to 240 seconds, due to existing deals with its three owners: Disney, Comcast and AT&T. Over in the UK, we haven’t suffered from quite as inconsistent an approach as in the US, but there is still viewer frustration with the ad experience on ITV Hub and All4, where the problem tends to be over exposure of the same ad. Therefore, this move to standardise ad break lengths for streaming platforms is one that should be embraced on both sides of the pond. An important shift in this space will be to limit the number of ads during each show, but have better ad targeting to minimise repetitive advertising and increase the ROI of ad spend. All of which can be accomplished by investing in identity resolution products that can support CTV devices. Last year Ofcom found that in the UK subscriptions to Netflix, Amazon and NOW TV have risen above those to traditional pay TV services. With Netflix and Amazon both ad-free and NOW TV only a limited ad funded model, it’s clear that there is a growing appetite for ad-free viewing models. A fact that is only further supported when you consider the role of the BBC and BBC iPlayer. But the picture isn’t entirely negative for ad-funded models. There is demand for great content on ad-funded services in the UK, with ITV Hub boasting over 1bn requests and 540m hours of TV watched. The ITV Hub mobile app has also been downloaded on over 27m devices across the country – with over 22m people now registered to ITV Hub database, including more than half of Britain’s 16-24 year olds. However, to continue to attract and retain younger viewers, the experience will have to improve. There are several areas where ad-supported streaming providers need to improve in order to remain top players in this space: Ad experienceAs explored above, both volume and repetition of ads can be a turn off for viewers, but with Brits already spending a total of £303.16m every month on TV streaming services, according to Finder.com, there is potential for free, ad-funded models to flourish as people hit a limit on what they are willing to spend. There are already signs of improvement with the ad experience, with ITV just signing a deal with Amobee to allow for addressable ads on ITV Hub, while Sky’s AdSmart technology remains best in class and has now crossed over the pond to be used by Comcast stablemate NBC. Server reliabilityA cursory search finds little evidence of ongoing reliability problems with Netflix, but much evidence of problems with ITV Hub and All4, which are both prone to crashing. To compete with bigger players with massive server farms, server capacity needs to be tackled. This is especially true when it comes to live events, where many people will recall ITV Hub’s famous fails during the World Cup. While even some of the larger players have had similar streaming issues (for example, Amazon’s move into live sports streaming when they had to pull UK streaming of the US Open Tennis due to user complaints), viewing experience should be prioritised as the space gets increasingly competitive. Getting the content rightAmazon and Netflix have huge content budgets, but UK broadcasters remain strong in this regard, Channel 4 has enjoyed viewing figures of 7.5m for the Great British Bake Off, while ITV pulled in 13.7m for I’m A Celebrity. By building on UK-specific content that speaks to UK audiences, ad-supported streaming services can continue to pull in more viewers. Mobile accessMore and more Brits are choosing to watch TV content on their smartphone or tablet, according to UKOM-approved comScore data. In fact, 6.5m adults visited the BBC iPlayer app to watch video on either a smartphone or tablet, edging out Netflix which attracted 5.8m Getting the experience right on mobile, with the option to download content so it can be viewed in areas of low or no signal, is key.If UK ad-supported TV stations can crack these key areas for their Connected TV offering then they will be set up to succeed and offer a true home-grown alternative to the US streaming giants.
