Media Square’s May‑2026 trial of Intent IQ’s real‑time identity resolution lifted CPMs by 34% and doubled RPM on previously unidentifiable inventory, all while staying GDPR‑compliant.
Paris – In a market where more than four‑tenths of web and mobile traffic now runs in environments that lack traditional identifiers or cookies, French publisher marketplace Media Square announced on June 30, 2026 that a pilot of Intent IQ’s Bid Enhancement solution delivered a dramatic lift in revenue on “ID‑less” inventory. The test, carried out in May, showed a 34 percent increase in cost‑per‑thousand impressions (CPM) and a two‑fold rise in revenue per thousand impressions (RPM) on inventory that previously could not be matched to advertisers through conventional programmatic channels.
The ID‑less Challenge
The ad‑tech ecosystem is in the midst of a structural shift. As privacy regulations tighten and browsers phase out third‑party cookies, a growing slice of the audience can no longer be identified by the identifiers that have underpinned programmatic buying for over a decade. Analysts estimate that more than 40 percent of global web and mobile traffic now falls into “cookieless” or “ID‑less” categories, forcing publishers to grapple with lower fill rates, reduced CPMs, and a fragmented demand landscape.
For publishers, the problem is twofold. First, inventory that cannot be linked to a known user profile is often de‑valued by demand‑side platforms (DSPs) that rely on data signals to bid competitively. Second, the regulatory environment—particularly the European Union’s General Data Protection Regulation (GDPR)—places strict limits on how user data can be collected, stored, and shared, making many legacy identity‑matching approaches untenable.
Intent IQ’s Identity Graph in Action
Intent IQ claims to address the gap with a patented identity‑resolution engine that refreshes its underlying data every 48 hours. The technology builds a deterministic Identity Graph, linking anonymous device or browser signals to historical demand data with an accuracy rate that the company says exceeds 90 percent on a daily basis. By enriching bid requests in real time, the solution enables programmatic auctions to consider previously unreachable inventory as if it carried a familiar identifier.
The core of the offering—Bid Enhancement—operates at the moment of the auction. When a bid request arrives without a conventional ID, Intent IQ’s system injects a probabilistic match derived from its graph, allowing demand sources to evaluate the impression using the same pricing logic they apply to identified inventory. Importantly, the process is designed to remain fully compliant with GDPR, as it does not rely on persistent cookies or personally identifiable information (PII) that would trigger additional consent requirements.
Media Square’s May‑2026 Pilot
Media Square, which positions itself as France’s leading marketplace for publishers, partnered with Intent IQ to run a controlled experiment across a subset of its French inventory. The trial focused exclusively on inventory that lacked any form of identifier at the time of the request. Over the course of the test, the publisher observed a 34 percent uplift in CPMs compared with baseline performance. More strikingly, RPM—an aggregate measure that captures both fill rate and CPM—doubled, indicating that the higher prices were not offset by a drop in the number of ads served.
The gains were not isolated to a single metric. According to the data released by Media Square, both fill rate and CPM rose in tandem, suggesting that demand partners were willing to bid more aggressively on the newly enriched inventory. The results echo findings from other publishers that have deployed Intent IQ’s technology in North America, where revenue improvements ranging from 20 percent to 120 percent have been reported in similar ID‑less environments.
Executive Perspectives
Erwan Le Page, Managing Director of Media Square, framed the outcome as validation of the company’s strategy to protect and grow publisher earnings amid a shifting privacy landscape. “As part of our ongoing commitment to maximizing publisher revenue, we continuously evaluate innovative technologies that can create value for our publishing partners,” he said. “We are extremely pleased with the results delivered by Intent IQ’s Bid Enhancement solution and look forward to expanding its deployment across our network.”
From the vendor side, Fabrice Beer‑Gabel, SVP of Strategic Partnerships at Intent IQ, highlighted the strategic timing of the test. “Our objective in 2026 was to introduce Bid Enhancement to the French market and demonstrate the value that publishers in North America are already realizing from identity‑driven monetization,” he explained. “Working with Media Square provided an ideal opportunity to validate the effectiveness of our solution for French publishers and show how ID‑less inventory can be monetized more efficiently while remaining fully compliant with GDPR.”
Why the Results Matter
The French digital advertising market, valued at several billion euros, has been particularly sensitive to GDPR constraints. Publishers that rely heavily on programmatic revenue streams have faced pressure to either abandon cookieless inventory or accept lower yields. Media Square’s test suggests that a deterministic, privacy‑first identity graph can unlock value without compromising compliance—a combination that has been elusive for many ad‑tech vendors.
Moreover, the rapid data refresh cycle (every 48 hours) addresses a common criticism of identity solutions: staleness. In a fast‑moving ecosystem where user behavior shifts daily, a two‑day update cadence helps ensure that the enriched signals remain relevant for real‑time bidding.
Competitive Landscape
Intent IQ is not the only player attempting to bridge the ID‑less gap. Companies such as The Trade Desk, LiveRamp, and Unified ID 2.0 have introduced their own identity frameworks, often relying on probabilistic matching or consent‑based data sharing. However, many of these approaches still depend on cross‑site tracking or require explicit user consent, which can limit scalability in Europe.
By contrast, Intent IQ’s deterministic graph claims to operate without persistent cookies, relying instead on a network of anonymized signals that can be matched to historical demand patterns. If the French trial holds up at scale, it could position the firm as a viable alternative for publishers seeking a GDPR‑safe path to monetizing the growing share of cookieless traffic.
Implications for Advertisers
For demand‑side platforms and advertisers, the ability to bid on previously opaque inventory expands the reachable audience pool without sacrificing data quality. Higher fill rates and CPMs suggest that advertisers are willing to allocate budget to ID‑less impressions when the underlying technology provides confidence in audience relevance. This could lead to a re‑allocation of spend from traditional, identifier‑rich inventory toward a broader, more inclusive media mix.
Outlook and Next Steps
Media Square plans to roll out Intent IQ’s Bid Enhancement across its full network after the pilot, according to internal sources. The publisher is also exploring the possibility of integrating the solution with its own header‑bidding stack to further streamline the enrichment process.
Intent IQ, for its part, intends to use the French results as a springboard for deeper penetration into the European market. The company has indicated that future updates will focus on reducing latency in the enrichment step and expanding the breadth of data sources that feed the identity graph—all while maintaining the 48‑hour refresh cadence that underpins its compliance narrative.
Bottom Line
The May‑2026 Media Square trial underscores a growing consensus in the ad‑tech community: identity‑resolution technology that respects privacy regulations can deliver tangible revenue lifts for publishers grappling with a cookieless future. By achieving a 34 percent CPM increase and a 100 percent RPM boost on ID‑less inventory, Media Square demonstrates that the economic penalty of a privacy‑first web can be mitigated—provided the right tools are in place.
As the industry continues to adapt to GDPR, the ePrivacy Regulation, and the broader shift away from third‑party cookies, vendors that can prove both compliance and performance will likely capture the attention of publishers worldwide. Intent IQ’s French pilot may well be an early indicator of how that balance can be struck.
