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

In case you missed it, Facebook recently announced that it would begin supporting animated GIF images and GIF-fanatics everywhere went: The decision by Facebook, which is rather late to the GIF party given that animated GIFs are already commonly used on sites like Tumblr, Reddit, Twitter, Imgur, BuzzFeed and more, virtually guarantees that animated GIFs will soon be commonplace (like it or not) for nearly everyone. It may even give Facebook an opportunity to re-engage Millennials who already frequently communicate using stickers, emoji, emoticons and animated GIFs. To make use of the new feature right away, Facebook users will need to paste a link to an existing GIF into their status update box. Users who have the “auto-play” setting activated will see GIFs posted by their Facebook friends looping through the animation automatically as they scroll through their news feed or a friend’s timeline. For the time being, at least, users are not allowed to upload GIFs to Facebook. While Facebook has not yet allowed animated GIFs to be used by Page operators, there’s still a huge opportunity for marketers in this move. That’s because marketers can still create their own clever animated GIFs hosted away from Facebook either on their own website or through partnerships with sites like Giphy — which already has a Facebook Messenger add-on. They can then encourage consumers to say what’s on their mind — via Facebook, text/chat, Twitter, etc. — using their branded animated GIFs instead of words. Subway, for instance, has a set of GIFs in Giphy that allow consumers to say they’re hungry by sending GIFs of animated sub sandwiches and people eating them to others. And Experian Marketing Services found that users of animated GIFs are hungry for branded content. In fact, they’re already seeking out branded GIFs to share in this way. Media and entertainment brands, of course, have a natural play in the animated GIF space since they already have content developed. They merely need to convert it into a few seconds of animation and fans of the show, movie, game, musician, etc. will take it and run. But even for marketers who don’t have existing content, animated GIFs present an option for producing rich (if not always the highest quality), engaging visual content that’s more affordable than video but a step up from fixed images. They also present on-the-go consumers who are increasingly looking for shorter more “snackable” content with a quick way to engage with a brand when they don’t have the time or interest in watching an actual video. To help marketers test the waters and create relevant GIFs, we looked at online search variations of “GIF” during the 12 weeks ending May 30, 2015 using our Hitwise® online intelligence platform. Some of the top variations and a few popular GIFs in each category are below. Funny GIFs: Animated GIFs are often used to put a smile on people’s face, so it’s no wonder that “funny” GIFs are the most commonly sought out. Babies and cats feature prominently in this category. Reaction GIFs: Among users, animated GIFs are a natural way to react to something a friend has said or shared. Reactions can run the gamut of emotions from “meh” to “oh no you didn’t.” Happy Birthday GIFs: Want your Happy Birthday wishes to be memorable and unique. Don’t say it with words; say it with an animated GIF! Does your brand play a role in helping people celebrate their birthday? Then why not help people say it as well. Crying GIFs: That teary emoji can only express so much emotional depth. Show you know how someone really feels with a crying animated GIF instead. Mind blown GIFs: Saying “OMG” is so yesterday. Why would anyone just tell someone they blew your mind when they can show them? No wonder “mind blown” animated GIFs are among the most commonly sought out. Source: Experian Marketing Services It’s still early days for animated GIFs in Facebook, but the opening of the door by the social media giant could prove to be the tipping point in the mass adoption of this medium that lies somewhere between an image and a video. In fact, animated GIFs may eventually prove so popular that consumers may come to expect and prefer them over non-animated content.

As part of our ongoing series which focuses on consumer and marketing trends around major holidays throughout the year, we’ve just released the Father’s Day Hot Sheet. Father’s Day gift-related searches Now that Mother’s Day has come and gone, consumers will be shifting their focus to dad. According to Experian Marketing Services’ Hitwise® online intelligence tool, searches for “Father’s Day” typically start to pop up on Mother’s Day. And searches for “Father’s Day gifts” tend to focus on affordable gift ideas that are personalized, unique and often handmade. In fact, two of the top variations of Father’s Day gift-related searches from 2014 were for “DIY” and “homemade” gifts. While many shoppers wanted the “best” gift for dad, others simply wanted something “cheap” or “last minute.” Finding a gift that dad will appreciate means looking for something that is personalized to him. As such, searches for Father’s Day gifts often contain additional information about the dad or, in many cases, grandpa. Examples commonly used in 2014 were “Christian dad,” “new dads,” “outdoorsy dads” as well dads who are wine or BBQ lovers. While many gift searches include information about the intended recipient, others mention details about the gift-giver or their relationship to the father. Among last year’s variations that included such details, nearly a third focused on gifts that were intended to be given by a “daughter.” Genderless references, such as “kids” or “children” were almost as common. Interestingly, fewer than ten percent were for gifts to be given by a “son.” About a fifth of searches included details about the age of the gift-giver (e.g.: “baby,” “toddler” or “first grader”), while others specified that the gift was to be given by the dad’s wife or girlfriend. Go, go, gadget dad! Gadgets and gizmos are always popular gifts for the techie dad. In fact, during the week immediately preceding Father’s Day last year, visits to Electronics and Appliance websites were up a relative eight percent from two weeks prior. Visits subsequently tapered off the following week. An analysis of search terms driving traffic to the Hitwise Electronics and Appliance industry the week ending June 14 versus May 13, 2014 also sheds some light on the specific items that Father’s Day gift-givers were likely to have been seeking out. Two GPS systems (“Magellan GPS” and “Tom Tom”) were among the top terms that grew search share in the weeks leading into Father’s Day last year. Likewise, “GoPro” appeared in two separate fast growing search terms. Gadgets like these and others listed in the adjacent table may be big gifts for the gadget-loving dad again this year. Gone fishin’ Fishing is a timeless family pastime enjoyed by millions of Americans. According to Experian Marketing Services’ Simmons® National Consumer Study, 28 percent of dads and 26 percent of kids ages six to 17 went fishing last year. As such, it’s no surprise that online searches related to fishing spike over Father’s Day weekend. On the Saturday before Father’s Day in 2014, searches including “fishing” were a relative 28 percent higher than they were the Saturday prior and 64 percent higher than they were the following Saturday. To better understand what kids and dads were seeking out for their fishing plans, Experian Marketing Services conducted an analysis comparing variations of “fishing” searches immediately before Father’s Day last year to those performed two weeks prior. It turns out the word “techniques” was almost 8.6 times more likely to appear in fishing-related searches just before Father’s Day than it was two weeks earlier and “tips” was four times more likely to be used. Likewise, “licenses” was used 2.3 times more frequently, which along with the higher use of “techniques” and “tips” is evidence that many would-be fishermen and women are occasional participants at best. The fact that “charter” and “cabins” were used at higher rates however suggests that other children and/or dads had something in mind beyond a lazy (and likely more affordable) afternoon at the local fishing hole. Gift items, too, like “reels,” “gear” and “tackle” were among those most disproportionately used in searches heading into Father’s Day.

Welcome! Who doesn’t like a warm welcome? Whether your customer is walking into your store or just signed up on your website to receive communications from you, she expects a warm reception. It’s important to make that first impression count. A welcome series helps the conversation open up between the customer and your brand. It sets expectations on the types and cadence of content the customer will receive. Welcome emails also garner 86 percent higher open rates than regular promotional mailings – not too shabby! In a recent webinar, Saks Fifth Avenue shared that they are constantly testing new and current programs to optimize the customer experience. As a result, they discovered that switching from batch-sending welcome emails to sending welcome messages in real time increased open, click and redemption rates significantly. Here’s an example of their welcome series: Saks’ results are consistent with Experian Marketing Services’ welcome email findings which indicate that emails triggered in real time receive up to 10 times the transaction rates and revenue per email vs. those that are batched. A welcome series has also been shown to increase retention by educating customers on new ways to use products and services they’ve purchased from your brand. These emails also can remind customers of the benefits they’ll reap from enrolling in your loyalty programs or credit card. … and welcome back Even if a customer has been welcomed and has interacted with your programs, a day may come when the customer goes silent. Reactivation campaigns are an effective way to get them to re-engage. Naturally, it’s important to target your dormant customers in a variety of channels so you can reach them more effectively. Maybe you’re wondering why I jumped from the warmth of a welcome series right into reality of needing a reactivation campaign. The reason? Marketers need to understand where a customer is in their lifecycle and come full circle with customers if they have parted ways. Marketers can pique the interest of a returning customer by telling them what’s new and reintroducing them to their brand. Carnival® Cruise Lines, for example, sends a welcome-back email that features the newest social networks, offers and deals its customers can take advantage of immediately. At the end of the day, customers expect to receive relevant and engaging messages throughout their entire relationship with a brand. Customer life cycle programs deliver just that.
