Key Takeaways Cookieless advertising means reaching and measuring audiences where third-party cookies do not exist — Safari, Firefox, iOS apps and connected TV. More than 40% of web and mobile traffic is already in those environments. Chrome kept third-party cookies, and the replacement never arrived. Google abandoned deprecation in July 2024 and retired most Privacy Sandbox APIs in October 2025.

For years, the advertising industry’s identity conversation has focused on a single challenge: maintaining addressability in the face of signal loss. As third-party identifiers declined, privacy regulations expanded, and consumer behavior became increasingly fragmented across devices and channels, the industry responded with significant innovation. New identifiers emerged. Identity graphs expanded. Deterministic and probabilistic approaches evolved. The focus was clear: preserve

As third-party cookies face complete obsolescence and Apple’s ITP continues to aggressively limit data retention across Safari and iOS, publishers and advertisers are confronting a massive addressability gap. Resolving identity across channels has transformed from a sophisticated marketing luxury into a foundational business necessity for digital monetization. However, with dozens of alternative ID vendors entering the landscape, identifying a sustainable,

Identity resolution is no longer a niche capability reserved for enterprise data teams. In 2026, it has become the operational backbone of every serious advertising strategy — the difference between reaching a real person and wasting an impression on a ghost. But despite its growing importance, the industry is still falling short. A new State of the Industry report by

In the current digital landscape, media buyers are facing a significant hurdle: the loss of granular performance data. For years, the Mobile Advertising ID (MAID) was the north star for tracking user journeys and optimizing campaigns on iOS. However, with the onset of Apple’s App Tracking Transparency (ATT) and the deprecation of IDFA, that star has faded. Today, the industry

While most of the industry is still mourning the loss of third-party cookies, top-tier marketers have already moved on to a more lucrative metric: Revenue Lift. ID Bridging isn’t just a technical workaround for Safari signal loss; it’s a strategic engine that connects fragmented identities into a cohesive, high-performance ROI machine. In the current landscape of digital advertising, “signal loss”

In the digital advertising ecosystem, the path to purchase is rarely a straight line. A user might see an ad on their Connected TV (CTV) in the morning, browse products on their mobile device during a commute, and finally convert on a desktop in the evening. Modern identity resolution has evolved beyond a static ‘link’ between devices. We are entering

The mobile app ecosystem is facing a paradox. While user engagement is at an all-time high, the traditional levers for in-app monetization—specifically targeted advertising and retargeting—have been disrupted by the deprecation of identifiers like the IDFA (Identifier for Advertisers). For publishers and advertisers, the challenge is clear: How do you maintain revenue and relevance when the old signals go dark?

The shift away from third-party cookies has created a paradox for publishers: a large portion of their high-quality traffic—often from default browsers like Safari, Firefox, and high-value mobile apps—is now considered “cookieless inventory.” While users are present, the traditional mechanisms for identifying and targeting them are gone, leading to significant signal loss and revenue erosion for publishers. This challenge means

As the digital advertising landscape shifts away from third-party cookies, publishers and advertisers are facing a critical challenge: signal loss. Without the traditional methods of tracking users across the web, addressability has plummeted, particularly on browsers like Safari and Firefox. Enter ID Bridging—a sophisticated technique that is reshaping how identity is resolved in a privacy-first world. Leading solutions, such as
