Cookieless

Cookieless describes marketing and measurement approaches that do not rely on third-party cookies, using instead first-party data, contextual signals, authenticated identifiers, and privacy-preserving techniques. It reflects the industry's shift toward durable, consent-based recognition.

The cookieless shift is driven by browser restrictions, mobile tracking limits, and privacy regulation, which together erode the third-party identifiers that once underpinned digital advertising.

A cookieless strategy leans on data you own and people knowingly provide, which is both more durable and more privacy-respecting than borrowed tracking.
