Cross Device Tracking
Cross-device tracking enables the cross-device analysis of visitors to a website.
The unique identification of a visitor on different devices can, for example
for example, through a newsletter or a login.
The etracker parameter et_cdi is used to transfer a value (identifier) that is used to match the website visitor.
Cross-device tracking is enabled by default for every etracker account.
Please note that if the parameter is transferred incorrectly , the visitor numbers can be irreversibly distorted!
The identifier is always stored hashed by etracker, irrespective of this, the identifier should already be transferred hashed for data protection reasons.
The identifier must be unique for each website visitor, otherwise different user profiles will be merged.
The parameter et_cdi can be set in the etracker parameter block or transferred with the wrapper.
