Kolayyet:
Reduced Conversion Loss by 40% with Meta CAPI
We reduced ad conversion losses by 40% with Meta Conversions API and GTM server-side tracking.
Kolayyet was experiencing high conversion loss in Meta ad campaigns. Pixel data was coming in incomplete due to browser restrictions and ad blockers.
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.
