BKM Kitap:
Boosting Conversion Measurement via Meta Conversions API
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.

The Problem
In addition to Meta Pixel, Meta Conversions API (server-side) integration was established.
Critical funnel events (ViewContent, AddToCart, InitiateCheckout, Purchase) began to be transmitted via server-side.
Data duplication was prevented through a robust event deduplication structure.
Match quality was improved by enriching user data through Advanced Matching.
Work Done
Existing Pixel Audit
We reviewed the Meta Pixel setup and identified missing and faulty events.
Meta CAPI Setup
We configured the Meta Conversions API via server-side GTM.
Deduplication
We set up event_id-based deduplication to prevent double-counting of browser and server-side events.
Results
Conversion loss decreased by 40%, ROAS increased by 22%, and the entire setup was completed within 2 weeks.
More Success Stories
Jack & Jones Türkiye
We reduced cart abandonment and clarified revenue tracking with GA4 e-commerce setup and checkout funnel optimization.
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.
