Where to find SEM ID?
The SEM ID is a unique identifier of your Sklik account required for SEM implementation. You can find it in Sklik → Account Settings.
Every Sklik account has one SEM ID assigned to it. If your account has store outlets linked for Seznam Shopping, each of those store outlets also has its own SEM ID. Using the SEM ID of the specific store outlet ensures that customer satisfaction survey invitations are attributed to the correct store.

E-shops connected to Seznam Shopping (store outlets)
If your Sklik account has store outlets linked for Seznam Shopping, each outlet has a separate combined SEM ID (which includes both the account and store outlet identifier). This combined SEM ID ensures conversions are sent correctly for collecting product reviews. Do not implement the standalone account SEM ID in this case.
Moving a store outlet to another account
If you move a store outlet to a different Sklik account, the combined SEM ID becomes invalid. You will be notified of this change and will need to update the SEM ID in your implementation.
SEM ID for Server-to-Server (S2S)
If you implement SEM using Server-to-Server measurement, you will need a separate identifier – SEM ID for S2S. It appears after enabling the Show advanced settings toggle in the top right corner of Account settings – Event Management.
