### BYD Türkiye

Due to increasing cookie restrictions and browser-based data loss, BYD Turkey was unable to fully measure the user journey. A significant portion of users and sessions remained invisible in GA4, limiting analysis and optimization processes.

To resolve this issue, a cookieless, first-party data-driven measurement infrastructure was established using Hardal CDP.

### BKM Kitap

For BKM Kitap, data collected via Meta Pixel remained incomplete due to browser restrictions, iOS updates, and user consent settings, leading to significant data loss in conversion measurement. These measurement gaps—particularly in purchase and funnel events—directly hindered campaign optimization.

To address this challenge, Meta Conversions API (CAPI) integration was implemented, strengthening the measurement infrastructure through a server-side data stream.
