1. Get the SEM ID
In Sklik → Conversions → select a conversion → Tracking code. Look for seznam_retargeting_id or sklik_id — 8-10 numeric characters.
2. Fill it in in DataNostro
Dashboard → Platforms → Sklik — just the SEM ID. Sklik doesn't use an access token; identification is done via the ID + IP/UA match.
3. Test it
Conversions in Sklik appear within 24 hours. For faster debugging, direct test traffic to a specific campaign and watch the raw conversions in the report.
