Third-party cookies are being restricted across browsers, with Safari and Firefox already blocking them and Chrome implementing new restrictions. Google's Privacy Sandbox APIs (Topics API, Protected Audience, Attribution Reporting API) offer privacy-preserving alternatives. Our Privacy Sandbox transition service audits your current third-party cookie dependencies, implements server-side and first-party data alternatives, and prepares your measurement infrastructure for the evolving browser privacy landscape.

Frequently Asked Questions

Chrome has introduced Tracking Protection for a percentage of users, with planned broader rollout. Safari and Firefox have blocked third-party cookies since 2020.
The Topics API assigns users to interest categories (topics) from their browsing history without cross-site tracking, enabling interest-based ad targeting without third-party cookies.
Via server-side first-party tracking (CAPI, GTM Server-Side), Enhanced Conversions (hashed email matching), and the Attribution Reporting API.
Not entirely — server-side tracking, hashed email matching, and modelling fill most of the gap. The key is implementing these now rather than reacting when cookies are removed.
For Safari and Firefox traffic (40%+ of users), first-party tracking matters now. For Chrome, implementing server-side and Enhanced Conversions builds resilience for when restrictions tighten.
