Sell-side decisioning is changing how publishers and advertisers collaborate, improving efficiency and fostering more meaningful connections. Experian’s syndicated audiences and data solutions help both sides reach the right audiences with greater transparency and privacy.In our Ask the Expert Series, we interview leaders from our partner organizations who are helping lead their brands to new heights in AdTech. Today’s interview is with Paul Zovighian, VP of Marketplaces at Index Exchange.
Sell-side activation vs. buy-side packaging
What’s fundamentally changed with sell-side decisioning, and how does it now diverge from traditional buy-side packaging?
Sell-side decisioning is programmatic’s next major evolution – one that redefines how intelligence enters the transaction. Advances in infrastructure and computing power now allow supply-side platforms(SSPs) to act in the crucial pre-bid moment, enriching impressions with context, quality, and data before they reach the buy side.
This isn’t just about efficiency; it’s about unlocking new value. Smarter requests mean buyers see only the most relevant opportunities, while publishers gain recognition for the true worth of their audiences and environments.
We’re still at the beginning of this shift. Many players still package inventory without engaging in real pre-bid intelligence. As the market matures, the companies that evolve toward sell-side decisioning will be the ones to set the pace for programmatic’s future.
Economic shifts with scaled curation
As curation scales, what economic levers shift for both publishers and buyers, and how do those shifts influence deal structure and media planning?
As curation scales, one of the most powerful levers is data. It’s the industry’s most valuable asset, and on Index it keeps its full worth. We don’t take a platform cut or add hidden fees, so data partners benefit from the clearest, most efficient economics in the market. Data vendors gain confidence that their economics aren’t eroded by a platform tax.
For publishers, this means stronger yield and more ad spend flowing directly into working media. When data retains its full value, it enhances how impressions are packaged, priced, and differentiated—driving more competition for quality inventory and more opportunities for revenue.
For buyers, it means compressed supply paths and total transparency – they know exactly what they’re paying for. With no intermediaries and full transparency into economics, buyers gain a clearer view of where their budgets go and the confidence that their investments reach real audiences in trusted environments. They benefit from cleaner supply chains, better performance, and more meaningful alignment between spend and outcome. The result is a healthier marketplace where both sides benefit from efficiency, fairness, and scale.
Moving decisions upstream for value
What decisions historically made in DSPs should now move upstream to publishers or SSPs to unlock more value, and which should remain buy-side?
Decisioning is no longer confined to demand-side platforms(DSPs). We can enrich impressions by applying intelligence — via data, algorithms, creative technology, and more, before they even reach the buy side — adding context, filtering out low-quality supply, and expanding audience discovery.
This isn’t about shifting roles; DSPs remain critical for campaign strategy, optimization, and budget allocation. The sell side simply ensures every bid request is smarter from the start, creating more value for all parties.
In doing so, we also alleviate pressure on DSPs — enabling more comprehensive data discovery by searching for signals at the top of the funnel, prior to optimization. That means DSPs can focus on what they do best, supported by a cleaner, more transparent supply path.
Index Marketplaces use cases explained
Index Marketplaces is designed to enable the strength of our partners, and Experian brings one of the broadest sets of demographic and audience insights in the industry. That scale enables a wide variety of applications, from more precise audience activation to deeper measurement and analytics.
What’s different on the sell side is how those insights are applied. By activating Experian’s syndicated audiences directly at the point of decision, their value is realized in real time and across the full scale of the open internet. Buyers gain a clearer path to relevant audiences, and publishers benefit from stronger alignment between data and media.
It’s an approach that ensures partners like Experian can maximize the impact of their assets while helping the market move toward more intelligent, performance-driven activation.
Identity signals with stronger privacy
For identity partners like Experian, what’s the right way to bring audience, context, and propensity signals into sell-side activation?
The beauty of sell-side decisioning is that it reduces the hops in how identity signals are applied. Without it, IDs have to travel through multiple platforms, creating extra handoffs and additional risks of data loss or leakage.
With sell-side decisioning, those signals are obfuscated under a deal ID and applied directly at the point of decision. That means audience, context, and propensity data are activated securely, without ever leaving the sell-side environment.
For partners like Experian, it’s the cleanest path to value: fewer hops, stronger privacy protection, and clearer economics for everyone in the chain.

FAQs
Sell-side decisioning allows publishers to add intelligence, like audience data and context, before ad impressions are sent to buyers. This makes the process more efficient and ensures advertisers see only the most relevant opportunities.
Traditional buy-side packaging happens after impressions are sent to demand-side platforms (DSPs). Sell-side decisioning moves some of that intelligence upstream, enriching impressions earlier and reducing inefficiencies.
Curation refers to the process of organizing and enriching ad inventory with data and context. For publishers, it leads to better yield and more ad spend going directly to their media. For advertisers, it means clearer, more transparent supply paths.
By applying audience and identity signals directly on the sell side, data stays within a secure environment. This reduces the number of platforms handling sensitive information, lowering the risk of data loss or leakage.
Experian provides demographic and audience insights that are activated directly at the point of decision. This helps advertisers reach the right audiences more effectively while ensuring publishers can maximize the value of their inventory.
When publishers and SSPs handle some decisioning earlier, DSPs can focus on campaign strategy and optimization. This creates a cleaner, more efficient process for everyone involved.
A deal ID is a unique identifier used in programmatic advertising to bundle audience and context signals securely. It ensures data is applied without being exposed or shared across multiple platforms.

Cross-device matching and pixel-based foot traffic attribution reporting empower digital marketers with greater control of location-based campaigns.RALEIGH, N.C. (PRWEB) AUGUST 04, 2020 Tapad, part of Experian a global leader in digital identity resolution, and Reveal Mobile, a leader in location-based marketing, today announced a collaboration that combines Tapad's digital cross-device matching technology and pixel-based attribution features with Reveal Mobile’s VISIT Local, the software that hundreds of digital agencies and brands use for location-based analytics. The partnership is designed to drive improved performance by optimizing ad targeting and messaging for location-based campaigns. Powered by Tapad’s privacy-safe cross device matching, marketers using VISIT Local to power location-based campaigns can enhance how they reach shoppers. When one member of a household shops for groceries, clothes, household goods or any other consumer item, a conversation between multiple members of the household typically takes place beforehand. With cross device matching, marketers can reach everyone who has influence over what to buy and where to buy it. VISIT Local users can expand location-based services with a single click to include devices that share the same household, including targeting across multiple devices owned by the same user, allowing advertisers to maximize messaging and increase their share of wallet among consumers. “VISIT Local has always given our customers access to high-intent location-based audiences. With the addition of cross device matching from Tapad, advertisers can boost audience sizes up to 300 percent while maintaining full confidence in quality and relevance,” says Brian Handly, CEO of Reveal Mobile. “VISIT Local users can now apply multiple criteria and attributes to a single location-based audience, giving them the advanced control and transparency they need.” As reliable attribution becomes increasingly complex for marketers and ad buyers who need to prove value, the addition of Tapad’s pixel-based foot traffic attribution to VISIT Local enables the measurement of actual campaign effectiveness by tying ad views to in-store foot traffic. This new feature, which will be available in VISIT Local this fall, lets Reveal Mobile customers understand who visited a retail location as a result of being served an ad, providing a more accurate view into return on ad spend during and after advertising campaigns. “Tapad’s goal is to empower marketers with digital advertising efficiencies at scale across devices,” says Mark Connon, COO of Tapad. “With cross device matching and pixel-based foot traffic attribution, marketers using VISIT Local can better address the consumer’s preferences and habits, and deliver them consistently actionable information on user behavior. These capabilities advance location-based advertising in ways marketers need and want.” In addition to these new features, VISIT Local’s location-based audience builder now enables marketers to create custom audiences made up of people who have visited different places on different dates. This gives VISIT Local users the ability to segment and create the most highly targeted audiences possible. For example, a marketer who wants to advertise for a chain of restaurants can easily target visitors of different competitors in different cities. Or a marketer who wants to advertise vacation destinations can target people who have been to various resorts at different times of year. Or a marketer who wants to advertise the release of new music can target people who have been to concert venues in different cities on different dates. “Many of our customers need to create highly custom audiences so they can run experiments, test messaging, and run increasingly competitive campaigns,” says Handly. “Everyone who uses VISIT Local can now apply multiple criteria and attributes to a single location-based audience, giving them the advanced control and transparency they need.”To learn more about Tapad’s digital identity resolution products, visit our identity solution page.

Overview Chartable leverages The Tapad Graph to improve cross-device attribution rates and remove non-addressable IPs for clients. Challenge Chartable needs to differentiate between consumer and potential business IP addresses to provide accurate household modeling and reduce excess data for their customers. Podcasting generally only has access to IP addresses as a form of digital ID which limits its ability to connect activity to individuals and extend it across all devices. The Tapad + Experian solution Using Tapad, now a part of Experian, Chartable is able to cut through the noise of IP data and discard any addresses deemed a shared IP or business. Then, Tapad + Experian connects individual users to their other digital IDs and users in their household; creating a richer attribution model for Chartable customers.

With the growth of digital marketing and the targeting capabilities associated with online outreach, many predicted that this would mark the end of direct mail advertising. But if Millennials have anything to say about it, that’s not going to happen anytime soon. Yes, believe it or not, Millennials are driving the resurgence of direct mail advertising, and many leading brands are now pivoting their omnichannel marketing plans to include direct mail. And with the USPS reporting more than 75.7 billion in marketing mail volume in 2019, this trend shows no sign of slowing down. Including direct mail in your plans may give your brand a better chance of reaching your audience. Why? 1. Millennials actually like getting mail.While most of us have decried “junk mail” as being environmentally unfriendly or just a pain to deal with, Millennials actually enjoy physical mail. Valassis recently cited research from USPS Customer & Market Insights stating that Millennials spend the most time sorting mail (about six minutes compared to the average, which is four minutes), plus they’re opening mail and reading it (at eight minutes versus the average of seven minutes). Valassis also conducted a study that showed that 68% of Millennials read print ads or inserts from retailers, and 64% prefer getting them through the mail. So, while digital outreach may be convenient, it hasn’t completely decimated the desire for that old-school, hands-on experience of opening and reading something that’s addressed to you. 2. Millennials respond to a multi-channel approach.Oftentimes, marketers think of omnichannel as being a combination of digital and TV, but when you add print into the mix, it can make an even bigger impact on Millennial audiences. Valassis found that 60% of consumers are more likely to make a purchase after seeing an ad when it’s presented across both offline and online channels, while 72% of Millennial parents say print ads encourage them to go online and make a purchase from that retailer. 3. Millennials think physical mail makes for a more personal approach.You’d think that e-mail would feel more personal, but with the influx of spam most people get, that’s just not the case. In fact, 67% of people see physical mail as being more personal than an e-mail, with seven out of 10 saying they prefer receiving actual mail over digital mail. And for marketers looking to make a one-to-one connection, this is music to their ears. With changing marketing plans, the mailbox has less competition than the inbox. Getting a catalog at their door with the perfect offer at the perfect time helps the marketer make the direct connection. 4. Direct mail lasts longer than digital mail.That may seem like an obvious statement, but there’s more to it than you think. When an e-mail arrives in someone’s inbox, it’s easy to ignore it, read the subject line and forget about it, or even just randomly delete it, if spam filters don’t take care of that on their own. But the average lifespan of a piece of direct mail is 17 days, which may account for how direct mail generates purchases five times larger than e-mail campaigns. It’s harder to ignore when it’s in your house and you have to physically handle it as opposed to just clicking a mouse to get rid of it. 5. Millennials trust direct mail.It’s true—research shows that 90% of Millennials think direct mail advertising is reliable. Plus, Millennials are 24% more likely to show mail to others, compared to 19% of non-Millennials… which means if they find a deal they like in the mail, they’re probably going to spread the word.
