Measurement that doesn't lose data.
Editorial hub on modern tracking, in the post-cookie era. Google abandoned its plan to remove third-party cookies, but their effectiveness is declining, and Privacy Sandbox was discontinued. The real answer: first-party data, server-side collection and orchestrated consent. Three pillar studies, with verifiable figures, plus a reference glossary.
- P·01
First-party data
Data collected directly from your customers, with their consent, through your own channels. With third-party cookies declining and Privacy Sandbox abandoned, it's no longer an edge — it's the foundation. Running reverse ETL on it is reported to cut CAC by 15-30%.
- P·02
Server-side
Collection moved out of the browser onto a server you control. Recovers 20-40% of the signal browsers, ad blockers and ITP lose — straight into the quality AI bidding relies on.
- P·03
Orchestrated consent
Consent Mode v2, mandatory in the EEA/UK since 2024. Implemented correctly, with modeling and server-side, it recovers 30-50% of conversions lost to consent refusal — through compliance, not despite it.
Studies
Three pillar pieces on measurement that holds up in 2026. Verifiable figures, primary sources.First-party data: why it became non-negotiable (and what happened to cookies)
Google abandoned removing third-party cookies, and Privacy Sandbox was discontinued in October 2025. What that actually means — and why strategy shifts to first-party data anyway. With real ROI: CAC −15-30%, ROAS +25-40%.

SourcesServer-side tracking: why you move measurement from the browser to your server
Browser tracking loses 20-40% of signal to ad blockers, ITP and browser restrictions. How server-side collection works, what you recover (~37% more conversions, +46% with Enhanced Conversions) and how it ties to Smart Bidding.

SourcesConsent Mode v2: how to recover conversions lost to consent refusal, the compliant way
Mandatory in the EEA/UK since March 2024. The 4 signals, the myth that server-side exempts you from consent, and why a correct implementation plus modeling recovers 30-50% of lost conversions — up to 60-70% with server-side.
