RESULTS

What actually changes when you deploy DataNostro.

+20–35 %

Match rate on Meta

Server-side events to Meta CAPI match Facebook profiles better — you send more parameters (hashed email, phone, fbp). Conversions, audiences, and optimization improve within days.

A typical range per the Meta CAPI benchmark (2024); the specific result depends on the quality of your user data and catalog.

+25–40 %

You see the traffic GA4 loses

Some users have an ad-blocker or aggressive ITP. A server-side request goes straight from your domain — unblocked, attributed, counted.

A range per public measurements (Stape, Simo Ahava); an audience with a higher share of iOS and tech-savvy users is at the upper end.

2 roky

Cookie life instead of 7 days

Safari ITP cuts first-party cookies to 7 days. The Cookie Keeper sGTM Power-Up rotates them server-side — attribution and remarketing survive whole seasons.

5 min

Setup, not weeks of DevOps

You fill in the GA4 Measurement ID, add a CNAME at your DNS registrar, and server-side is running. No GCP console of your own, no Cloud Run, no Docker.

99,9 %
