Ditch the cookie, not the data with the next evolution of contextual targeting
Today, we’re excited to announce Contextually-Indexed Audiences, a game-changer in contextual targeting. Experian’s new solution offers advertisers a powerful, privacy-safe solution that combines the precision of deterministic audience targeting with the flexibility of contextual targeting. Powered by real-time analysis from two million websites, access to 1,400 trusted audience segments, and easy activation through the top demand-side platform’s contextual marketplace or Audigent private marketplaces (PMPs), this solution offers advertisers a scalable way to reach their target consumers.
With this solution, advertisers can reach consumers on websites that over-index for visitors with the demographics, behaviors, or interests, they are looking to target. For example, an automotive brand can select Experian’s “Contextually-indexed in-market for a luxury electric car” audience segment and reach consumers when they are browsing websites that often attract that exact segment. Best of all, this is done in a privacy-safe way since it’s not reliant on cookies, mobile ad IDs (MAIDs) or other user identifiers.
How Contextually-Indexed Audiences work
Contextually-Indexed Audiences harness advanced machine learning technology to move beyond traditional keyword-based strategies. The solution works in three steps:
- First, it analyzes traffic from over two million websites and mobile apps to identify the types of frequent visitors to those platforms.
- Next, using Experian’s Digital Graph, it resolves the identities of those visitors and maps them to more than 1,400 of Experian’s Syndicated Audiences, determining which audiences are most overrepresented on each site.
- Finally, the relevant audiences are assigned to those sites, allowing advertisers to deliver ads to people in those audiences while they are actively browsing the websites — without relying on user identifiers.

Customer success story
A leading auto manufacturer was among the first clients to activate this new solution while we were in beta. The goal was to identify new contextual targeting solutions that focus on privacy while maintaining scale and performance. The client identified two key target audiences: first-time vehicle buyers and experienced buyers. The initial campaigns using this new solution were highly successful. Even as the campaign scaled to twice the original volume, it continued to deliver three times the targeted click-through rate (CTR) goal.
“Partnering with industry leaders like Experian, we’re pushing the boundaries of contextual targeting with innovative data strategies that offer buyers greater flexibility and improved performance. These advanced contextual solutions are exciting as they not only drive results but also have the same privacy safeguards as traditional contextual targeting.”
Matt Griffith, CTO & Co-Founder, Audigent

One of the biggest challenges marketers face when planning digital advertising campaigns is getting an adequate number of impressions that yields measurable results at the lowest possible cost. As agencies, operators and advertisers are increasingly challenged about media budget, it is more important than ever to plan campaigns that generate enough information at the lowest possible cost. Through our design, deployment and measurement of advertising on a variety of platforms, Experian has developed best practices when planning digital advertising campaigns. We share some of these here, to help marketers with future campaign planning to maximize marketing effectiveness at a minimal cost. Using Path to Purchase to Determine the Right Number of Touch Points The Path to Purchase Funnel provides a framework to determine the number of touchpoints required to turn a prospect into a buyer. There are various phases the consumer goes through at each contact, and these phases dictate the number of touch points (or ‘touches’) required to induce a purchase. In the table below, we’ve described what these phases are, and the number of touch points required for those phases. The required number of touches will vary greatly among marketers, who must consider the expected time for a prospect to make decisions, competition in the marketplace, the novelty of the offer, and the level of engagement of the audience. For example, 15-second or 30-second audio and video ads played during scheduled breaks in programming may require more repetition than an ad played at a moment of high engagement, such as when the user interacts with the app, or during a “pre-roll” advertisement view prior to streamed content. Determining the Target Number of Impressions Needed to Persuade The next step involves determining how many exposures will be required to get the impressions or touch points needed to satisfy the consumer’s path to purchase. Let’s say a marketer has decided that four impressions are enough to make the case for the consumer to purchase, and that the marketer plans to reach 1 million prospects during the campaign. Perhaps the most intuitive solution is to provide four impressions for each reached prospect, such that 4 million impressions would be served during the campaign. However, during a normal digital campaign, some prospects will have zero impressions while others will have many. Because of this, we recommend planning to reach a target fraction (typically 80%) of the audience to receive the required number of impressions for purchase. The following table shows the predicted percent of audience exposed by average number of impressions served. Factoring Advertising Half-Life into Impressions Required Advertisement decay, or the fading consumer memory that reduces ad effectiveness, should also be factored into determining the right number of impressions for a successful campaign. For example, if a campaign length is planned to be 6 weeks, but the half-life of the advertisement is only three weeks, then more impressions would be needed to attain the number of touches required for the path to purchase. When planning campaigns for our partners, we adjust the target mean exposure frequency by the square root of the proportion of campaign length over advertisement half-life. For example, assuming a 3-week half-life and a 6-week campaign, we should multiply our target 5.5MM impressions by to get 7.78MM impressions. In the table below, we’ve demonstrated several scenarios of varying advertisement half-life. Other Considerations During Post-Campaign Analysis Once the campaign is completed, Experian recommends analyzing the distribution of impression frequency to determine how closely the actual impression frequencies matched to what was predicted. If frequencies do not align with the predicted, check to see if these assumptions are met: Make sure that advertising impressions are independent of each other. If rules are in place such that a prior impression affects the likelihood of a subsequent impression, this can affect the impression frequency. Check that the entire targeted population is on the ad platform long enough to be available for targeting. Some campaigns may have been instructed to be deployed in phases, which could limit the number of impressions to be delivered. Confirm that exposures can only occur one at a time, so that the impressions are deployed at distinct time intervals, giving the consumer the opportunity to view the advertisement Planning a successful campaign is critical for a test-measure-learn environment for an agency, operator, platform or advertiser. While initial up-front costs can be expensive, the long-term value to the business is significantly greater if tests are designed and administered appropriately. As a result, spending a little extra time thinking about your consumer’s path to purchase, exposure frequency, and the half-life of your advertisement can pay significant dividends in developing your digital advertising strategy.
