Criteo Chrome Sandbox Study Warns of CPM Drop
The article analyzes Criteo's Chrome Sandbox testing, which compared 3P cookies, Sandbox, and contextual targeting. Key findings include a 60% revenue decline for publishers using Sandbox, and a 78% drop when considering all tested publishers (only 55% had adopted Sandbox). Latency reportedly rose by 100% in Sandbox scenarios. The CMA argues Sandbox should not be released in its current form and plans to delay cookie deprecation, while the piece notes broader uncertainties about post-cookie targeting, including potential identity-based workarounds and market dynamics (e.g., bidder behavior, logins, publisher consolidation). The discussion emphasizes real-world complexity beyond isolated tests and highlights the regulatory and competitive context shaping ad tech's transition away from third-party cookies.
Significant implications for post-cookie advertising and publisher economics; regulatory context and platform changes drive industry impact.

Privacy Sandbox: Mixed Results but Valuable Insights for Investors
The AdExchanger piece surveys publishers and tech companies that invested heavily in Chrome's Privacy Sandbox testing since 2019, highlighting a divide between expectations and outcomes. Adform dedicated more than 1,000 days of development by about 230 developers, with 50–70 engineers working part-time on Sandbox efforts and spending more than a few hundred thousand dollars to participate in Google's testing grant (which required matching). After Google reduced cookies for 1% of Chrome traffic to support Sandbox, advertisers contributed roughly $30,000 to $100,000 each. NextRoll reoriented about two-thirds of its DSP team to Sandbox testing in 2023, while PubMatic deployed 30–40 engineers on Protected Audiences for 6–9 months (peaking at 10% of engineering resources). Mediavine and Criteo found some benefits in topics and audience tooling, but with limited monetization and uncertain long-term investment. Raptive focused roughly 80% of its audience-id work on Sandbox; overall, testers view the project as a valuable privacy discussion catalyst, though not a guaranteed path to post-cookie profitability.

AI Disrupts Job Applications, Skills-Based Hiring Rises
The traditional resume is becoming obsolete as AI allows candidates to generate endless applications, forcing companies to rethink hiring. A 2025 study shows UK graduate employers received a record 140 applications per vacancy. Experts like Barb Hyman (Sapia.ai) advocate for skills-based hiring, which assesses candidates on demonstrated abilities rather than employment history. Around two-thirds of UK organizations have adopted this approach, per Michael Page research. Companies like Taktile and PMG now assess candidates through practical exercises and interpersonal skills, moving away from paper-based evaluation. AI is also seen as reducing human bias in screening, though final decisions remain with human teams. The shift emphasizes continuous learning and adaptability over static credentials.
