AI learns what your data teaches in 2025, "good data" in AI means accurate, current, consented, and easy to connect, or your models lose relevance and your investments underperform. Experian is leading this next era of responsible data where trust, transparency, and innovation come together to make marketing more human, not less.What makes data “good” in the age of AI?
In AI-driven marketing, data quality now defines success. “Good data” in AI isn’t about volume; it’s about the balance of accuracy, freshness, consent, and interoperability. As algorithms guide decisions, they must learn from data that’s both accurate and ethical.
At Experian, we believe good data must meet four conditions:
1. Accurate
Verified and anchored in real human identity.
2. Fresh
Continuously updated to reflect today’s consumers.
3. Consented
Collected and governed transparently.
4. Interoperable
Easily integrated across platforms through a secure, signal-agnostic identity spine, enabling seamless data activation.
This is the data AI can trust and the data that keeps marketing relevant, predictive, and privacy-first.
Why does data accuracy matter more than ever?
AI models are only as intelligent as their inputs. Incomplete or inconsistent data leads to bad predictions and wasted spend. As the industry moves toward agentic advertising, where autonomous systems handle campaign buying and optimization, data accuracy becomes even more critical. If your ad server or audience data is flawed, these new AI agents will simply automate bad decisions faster.
Experian applies rigorous quality filters and conflict resolution rules to ensure our data is both deterministic and accurate. Deterministic signals alone don’t guarantee accuracy; they must be verified, deduplicated, and contextualized. Our identity resolution process anchors every attribute to real people, giving brands and platforms the confidence that every insight stems from truth, not noise.
Our data is ranked #1 in accuracy by Truthset, giving our clients confidence that every decision they make is backed by the industry’s most reliable insights.
Just because it is deterministic, doesn’t mean it’s highly accurate. You still need to refine and validate your data to make sure it tells a consistent story. You need to anchor your data around real people.
Why does AI need fresh data?
Outdated data can’t predict tomorrow’s behavior. AI thrives on recency.
At Experian, our audiences are refreshed continuously to mirror real-world signals, from purchase intent to media habits, so every campaign reflects what’s happening now, not six months ago.
And we don’t just advocate for fresh data, we rely on it ourselves. Our own AI-powered models, used across our audience and identity platforms, are continuously retrained on the most current, consented signals. This allows us to see firsthand how freshness drives better accuracy, faster optimization cycles, and more relevant outcomes.
But freshness alone isn’t enough. With predictive insights, our models go beyond describing the past. They forecast behaviors, fill gaps with inferred attributes, and recommend next-best audiences, helping you anticipate opportunity before it happens.
Fresh and predictive data means you’re reaching people in the moment that matters and shaping what comes next. With AI, that’s what defines performance.
How do consent and governance build trust in AI?
Responsible AI starts with responsible data. With 20 U.S. states now enforcing privacy laws, data compliance isn’t optional, it’s operational.
At Experian, privacy and compliance are built in. Every data signal, attribute, audience, and partner goes through our rigorous review process to meet federal, state, and local consumer privacy laws. With decades of experience in highly regulated industries, we’ve built processes that emphasize risk mitigation, transparency, and accountability.
Governance isn’t just about regulation, it’s also about innovation done right. We drive transparent and responsible innovation through safe, modular experimentation, from generative applications to agentic workflows. By balancing bold ideas with ethical guardrails and staying ahead of evolving legislation, we ensure our innovations protect consumers, brands, and the broader ecosystem while moving the industry forward responsibly.
Compliance and governance aren’t just boxes to check; they’re the foundation that gives AI its license to operate.
How does interoperability enable AI’s full potential?
AI delivers its best insights when data connects seamlessly across fragmented environments. Our signal-agnostic identity spine allows data to move securely between platforms (connected TV, retail media networks, and demand-side platforms) without losing context or compliance.
Interoperability isn’t just about moving data between systems; it’s about connecting insights across them. When signals connect across environments, AI gains a more complete view of the customer journey revealing true behavior patterns, intent signals, and cross-channel impact that would otherwise remain hidden.
This unified perspective allows AI to connect insights in real time, improving predictions, performance, and personalization while protecting privacy.
Where do AI and human oversight meet?
AI can make marketing more predictive, but people make it meaningful. At Experian, our technology brings identity, insight, and generative intelligence together so brands, agencies, and platforms can reach the right people with relevance, respect, and simplicity.
Our AI-powered models surface connections, recommend audiences, and uncover insights that would take humans months to find. But our experts shape the process, crafting the right inputs, ensuring data quality, reviewing model outputs, and refining recommendations based on industry knowledge and client goals. It’s this partnership between advanced AI and experienced people that turns predictions into actionable, trustworthy solutions.
What “good data” looks like in action
“Good data” becomes most powerful when it’s put to work. At Experian, our marketing data and identity solutions help brands and their partners connect accurate, consented, and interoperable data across the ecosystem, turning insight into measurable outcomes.
When Windstar Cruises and their agency partner MMGY set out to connect digital media spend to real-world bookings, they turned to Experian’s marketing data and identity solutions to close the attribution loop. By deploying pixels across digital placements and using Experian’s identity graph to connect ad exposure data with reservation records, we created a closed-loop attribution system that revealed the full traveler journey, from impression to confirmed booking.
The results were clear: 6,500+ bookings directly tied to digital campaigns, representing more than $20 million in revenue, with a 13:1 ROAS and $236 average cost per booking. Attributed audiences booked $500 higher on average, and MMGY’s Terminal audience segments powered by Experian data achieved a 28:1 ROAS.
This collaboration shows that responsible, high-quality data and AI-driven insights don’t just tell a better story; they deliver measurable business performance.
Why the future of AI depends on “good” data
The next phase of AI-driven marketing won’t be defined by who has the most data, but by who has the best. Leaders will:
Operate with clear data principles grounded in transparency and truth
Build consent and compliance into every workflow
Keep data accurate, current, and interoperable
Pair automation with human oversight
AI success starts with good data. And good data starts with Experian, where accuracy, privacy, and purpose come together to make marketing more human, not less.

The UK digital advertising market is worth £13.44bn, an increase year-on-year of 15%, reveals the 2018 IAB UK & PwC Digital Adspend Study. Report highlights The majority of all growth is coming from smartphone advertising, which has increased by £1.65bn (35%) from 2017. Smartphone advertising now represents 51% of all UK digital ad spend, up from 45% in 2017. Video is now the largest display format (£2307m), overtaking standard display banners (£1486m). Outstream/social in-feed has increased its majority in total video spend, now occupying a share of 57%, up from 52% in 2017. Social revenue now represents 23% of all digital ad spend. Growth is predicted to slow during 2019, with 5% estimated growth (+9% digital, +11% display, +9% search) compared to 15% in 2018. 2018 marks the tipping point towards a mobile-first ecosystem “For the past few years, industry commentators have been hailing the year of mobile. Each January the predictions come and the waiting commences for evidence to mark a tipping point, a shift to a mobile-first digital ad ecosystem. Well, drumroll… it was 2018! The latest Adspend report from IAB UK and PwC reveals that spend on smartphones outstripped spend on desktop for the first time last year. Brands spent 51% of total spend (which stands at £13.44 billion) on smartphones in 2018, up from 45% in 2017 – a significant milestone in the evolution of digital advertising. “This evidence shows that advertisers are increasingly thinking mobile-first. Growth in investment has historically lagged behind the amount of time spent on the device and we expect to see growth continue at a rapid pace to keep up with audience behaviour – two thirds of time spent online is now on mobile, according to UKOM. Other areas of growth highlighted by the report include video, which accounts for 44% of the total display market, while mobile video now makes up 51% of smartphone display. This is no doubt down to bigger mobile screens, better 4G and more readily available WiFi making video ads an increasingly attractive option. “Across the board, advertisers are investing in digital for longer-term brand building as well as short-term activation, with the direct-to-consumer market helping to drive this trend. What’s more, digital continues to be an accessible and popular route to market for businesses of all sizes, from leading advertisers to SMEs.” Tim Elkington, Chief Digital Officer, IAB UK Content & context crucial for attracting audiences “As people spend more and more of their time on mobile, it’s comes as no surprise that advertisers will follow where audiences are with their marketing spend. “Video has been the driving force in this growth, indicating that engaging visual content is still key in helping brands to achieve great results and to capture consumer attention in a vast sea of digital noise. “Video still has a way to go if it is to reach the level of effectiveness of traditional formats like cinema, but it will be interesting to see how the format develops over the next year or so. Ultimately, brilliant content and properly considered context are crucial for advertisers hoping to attract relevant audiences and build strong brands long term.” Kathryn Jacob OBE, CEO, Pearl & Dean Mobile-first approach driving investment in user experience “As a mobile-first approach has become the norm for many businesses, we’ve seen significant innovation and investment in the user experience that has fuelled the rise in mobile commerce. “Yet, for some years, limitations in the technology and formats available have meant that mobile advertising couldn’t always keep pace with changing consumer behaviours – delivering weaker performance when compared to desktop. “Fortunately, mobile has made huge strides in recent years. Mobile advertising affords great targeting opportunities for brands and a more interactive and immersive experience for consumers. “There is no reason to doubt this trend will continue as advertisers design their media, creative, and targeting strategy with mobile at the heart – optimising performance, enhancing the customer experience, and delivering the best results.” James Cragg, UK Managing Director, Tug New technologies to improve investment efficiency “The UK digital ad market has continued to grow despite the various challenges that the market has faced, including the current socioeconomic climate and general changes in the industry. As spend increases, it’s important to look at how media buying can be made as efficient as possible, minimising waste and maximising the return on investment. “Marketers will start to look to new technologies, like AI, to offer an impartial and more efficient approach to media buying, allowing marketers to measure effectiveness of campaigns and allocate spend accordingly.” Carl Erik Kjaersgaard, Chief Executive, Blackwood Seven Industry going from strength to strength “This significant growth in ad spend is great to see and shows that our industry is going from strength to strength. It’s especially good to see that as advertisers invest more and more in digital advertising, they’re becoming more considered in where they’re spending their money – with a large portion of the growth coming from companies that are part of IAB’s Gold Standard. “At The Trade Desk, we’ve long been ambassadors for the importance of transparency. These findings show that it isn’t just the right thing to do, but makes good business sense as advertisers increasingly choose partners who are demonstrating a commitment to best practice.” Anna Forbes, UK General Manager, The Trade Desk Advertisers embracing mobile “As consumers spend more of their time online, it’s no surprise that digital ad spend has continued its rise, up 15% to £13.4bn. With digital, in every sense, becoming further embedded in our daily lives, it is inevitable that this number is set to rise further next year. “Given the vast majority of people using their smartphone as their primary digital device, evident from site traffic stats we see across the board, the IAB report shows that advertisers have started to fully embrace this shift by following with ad spend. Over the last few years, a combination of faster wireless connectivity along with more capable devices has made it the go-to device for consumers to get online. This is set to continue over the next few years with 5G and even faster, more capable smartphones arriving (i.e. foldables) that will further cement ‘mobile’ as the main digital device to reach consumers.” Wajid Ali, Head of Paid Search, ForwardPMX Budgets must go to professionally produced content “In the IAB’s latest ‘Digital Adspend Study’ it is positive to see that outstream continues to dominate video spend, showing close to a 10% year-on-year increase. “Unsurprisingly, the study highlights that mobile is the most important distribution device (76% of all video spend is on the smartphone), and it’s great to see the format we invented dominating that space. “However, it’s now more pertinent than ever that clients and agencies invest their outstream budgets into professionally produced content and not social infeeds. Budgets must go where content is being produced, rather than aggregators and distributors, where the content is read rather than where a click happened. “We must remember how important local, national, and vertical press are to the global digital ecosystem. By unifying the best publishers at scale, delivering mobile-optimised creativity and outcome-orientated distribution, we are fighting to ensure publishers are getting their fair share of revenue in comparison to the social platforms.” Justin Taylor, UK MD, Teads UK market in robust health “The latest IAB digital ad spend report shows encouraging signs that the UK digital advertising market is in robust health, with mobile advertising continuing its upward trend. “The rise of up-and-coming ad formats like Shopping Ads, Google’s Responsive Search Ads, and Facebook Messenger Ads show that advertisers are looking for ways to capture consumer attention in the evolving digital landscape. As a result, the lines across search, social, and e-commerce are more blurred than ever with the introduction of features like Checkout for Instagram and Shopping ads on Google Images. Furthermore, with the rapid growth of Amazon’s ads business, e-commerce has quickly emerged as a third pillar of digital advertising, making it vital for marketers to have a complete view of the customer journey across channels and devices, if they hope to more accurately understand campaign performance and attribution.” Wesley MacLaggan, SVP of Marketing, Marin Software Digital identity resolution essential in understanding customer journey “Last year’s figures show that UK ad spend is starting to mirror the behaviour of consumers who, according to UKOM data, spend two-thirds of their time online on a smartphone. The fact that mobile ad spend now surpasses that of ad spend on desktop highlights marketers’ understanding that digital identity resolution is essential, not a nice-to-have. “Appreciating the cross-device behaviours of consumers allows brands to gain a better understanding of the customer journey and build stronger relationships with their audiences long term.” Tom Rolph, VP EMEA, Tapad, a part of Experian.

OpenAudience promises the targeting capabilities of a walled garden but without the restrictionsOpenX has lifted the lid on a targeting solution it claims will offer people-based advertising opportunities outside of the industry’s walled gardens such as Facebook and Google. Dubbed OpenAudience, the supply-side programmatic player claims the new offering is powered by proprietary data assets and is supplemented by data partnerships with partners such as LiveRamp and Tapad, a part of Experian. Initially available in the U.S., OpenAudience has a user graph of 240 million monthly users and is currently being tested with multiple marketers with a general rollout planned for the third quarter of 2019. Speaking with Adweek, OpenX CEO Tim Cadogan said the rollout would help differentiate it among its peers as for the most part ad exchanges have marketed themselves based on their impression count, not necessarily addressable audiences. Compare this with Google and Facebook, both of whom account for almost 60% of U.S. ad spend, although this is disproportionate to the amount of time spent with their properties, according to Cadogan. “The thing that has given Facebook and Google so much power is that they have people-based systems [for ad targeting] that are simple to use and operate with a massive scale that are effective, and programmatic hasn’t kept pace with that,” he said. Cadogan cited the findings of a further study by eMarketer, which indicated that marketers are increasingly reliant on such walled garden players for their online inventory supply with the latest launch geared towards capitalizing on that. The latest launch is the culmination of the California-based company’s recent strategic overhaul, namely its attempts to get to grips with an identity-based solution that provides options outside of the walled gardens. Also speaking with Adweek was Todd Parsons, OpenX’s chief product officer, who offered further insight into how OpenAudience operates including how it uses its recently sealed relationship with Google Cloud Platform and machine learning to ape the efficacy of walled garden advertising solutions. “We had to build a matching technology, which made it possible for us to talk about monthly active users instead of talking about cookies or devices,” he explained. “And it took several quarters of staffing up with the right people from the consumer data and identity space.” OpenAudience’s matching technology works by using the identity and cookie matching capabilities of cross-device specialist Tapad and data onboarder LiveRamp to formulate a persistent, deterministic ID which can then be used to match advertisers with audiences on its ad exchange. “So, the idea isn’t for us as a company to put our future into one provider,” added Parsons. “It is to provide a matching technology that uses the best of several.” OpenAudience will also include involve additional tie-ups to offering further demographic information on the 240 million monthly U.S. users such as location, etc., which is currently in testing. “We felt like we needed to be very different about enabling marketers and publishers to activate against that data,” added Parsons. He further added that OpenX wants to rival Facebook’s levels of service when it comes to helping publishers monetize audiences on the social network, except this time on the open web. “No one has actually pushed identity and consumer data into the hands of publishers in a way that you might unify the view of audiences across many websites.” OpenX’s Cadogan summed up the OpenAudience offering and how it may look to advertisers when he said, “Imagine the open web is one publisher, and this lets buyers look at it as a single entity and market to them accordingly.” Contact us today
