Third-party cookies dying has been “coming soon” for so long that a lot of Indian marketing teams have stopped taking it seriously. That’s a mistake regardless of Chrome’s exact timeline, because the bigger shift already happened: iOS App Tracking Transparency gutted third-party tracking on mobile years ago, ad blockers strip cookies for a meaningful share of desktop users today, and India’s own Digital Personal Data Protection Act is pushing consent requirements that make third-party tracking legally messier regardless of what browsers do. The infrastructure you built your retargeting and attribution on is already less reliable than your dashboards suggest.
What actually breaks
Retargeting campaigns that rely on third-party pixels following users across sites lose accuracy first - you’re already seeing this if your retargeting audiences feel smaller or staler than they used to. Attribution modeling that stitches together a customer’s journey across multiple sites and sessions gets noisier, which means your “last-click” and “assisted conversion” numbers are quietly becoming less trustworthy. And lookalike audience modeling, which depends on rich third-party behavioral data, has less raw material to work with.
First-party data isn’t a workaround, it’s the better asset
The honest framing here: first-party data - information customers give you directly, or that you collect through your own owned properties with consent - was always more accurate and more valuable than third-party data. It just took a forcing function to make brands invest in collecting it properly. A customer’s actual purchase history, their explicit preferences, their direct engagement with your app or site tells you more than an inferred behavioral profile ever did.
What we’re actually building for clients
- Zero-party data capture at the right moments. Preference centers, post-purchase surveys, loyalty program sign-ups - asking customers directly for information, in exchange for a clear benefit (better recommendations, early access, a discount), rather than inferring it indirectly.
- A proper customer data platform, even a lightweight one. Unifying purchase history, on-site behavior, and email/SMS engagement into one profile per customer, instead of scattered across five disconnected tools that don’t talk to each other.
- Server-side tracking and conversion APIs. Moving conversion tracking from the browser (which is increasingly blocked) to server-side integrations with Meta’s Conversion API and Google’s Enhanced Conversions, which are far more resilient to browser-level restrictions and generally more accurate besides.
- Consent infrastructure that’s actually usable. A consent flow that’s DPDP-compliant but doesn’t tank your opt-in rate through bad UX - this is a design problem as much as a legal one, and most implementations we’ve audited get it wrong in one direction or the other.
What this means for Tier 2 and Tier 3 audiences specifically
First-party strategies have a particular advantage for brands growing into India’s smaller cities: direct channels like WhatsApp and SMS, built on data customers gave you willingly, tend to outperform programmatic retargeting in markets where third-party data was already thinner to begin with. If you’re expanding into these markets, first-party infrastructure isn’t just a cookie-deprecation fix, it’s arguably the better acquisition channel from the start.
Where to actually start
Don’t start with a big platform purchase. Start by auditing what first-party data you’re already collecting but not using - most brands have more sitting in their existing CRM and order database than they realize, just not stitched together or acted on. We usually find the highest-leverage first move is server-side conversion tracking, because it directly improves ad performance measurement within weeks, before any of the longer-term data infrastructure work is even finished.
