Why is server-side tracking critical at scale?

Because on large budgets, a few lost attribution points mean significant misallocated spend. Server-side recovers a meaningful share of the signal lost on the browser and gives algorithms a reliable base to optimize on real margin.

Does server-side replace classic pixels?

No, it complements them. Pixel + server-side with deduplication offers the most reliable coverage: the browser captures what it can, the server secures the rest.

The challenge · steering on reliable data

With the end of third-party cookies and browser-tracking limits, Eleganza risked steering large media budgets on incomplete data. At tens of millions in revenue, every unmeasured conversion degrades algorithm optimization and distorts investment decisions. The goal: reliable measurement at scale.

End of third-party cookies, degraded browser signal.
Large media budgets optimized on incomplete data.
Attribution distorted at the scale of tens of millions.

The approach · server-side at the core

Webotic deployed server-side tracking (server-side GTM + Meta CAPI) to make every conversion reliable, rebuilt clean attribution, then steered acquisition on that real data. Consolidated reporting enabled fast investment decisions with controlled scaling.
