Set up your own Tracking Domain

Avoiding data loss due to ad blocking and cookie runtime restrictions by browsers

In certain configurations, ad blockers prevent data collection with etracker Analytics, even though the use of etracker respects the privacy of users and complies with data protection regulations. In a similarly undifferentiated manner, Safari Intelligent Tracking Prevention (ITP) and Firefox Enhanced Tracking Protection (ETP) ensure that tracking cookies are limited to 7 days and 24 hours respectively.

These restrictions can be overridden for etracker Analytics by means of a separate tracking domain. Usually, the ad blockers do not prevent scripts that originate from the same domain. Likewise, the cookie limitations of browsers do not take effect with 1st party cookies from own domains.

The use of an individual tracking domain is possible in every etracker Analytics Edition and is associated with an additional fee of € 49 net per month. Please contact our Customer Service for further information. To set up your own tracking domain, proceed as follows:

1. Define a name for your tracking domain. This should be based on the name of your website domain.

Website domain name:
Possible/recommended name for your own tracking domain:

The desired own tracking domain must be unique, i.e. not already assigned elsewhere.

2. Set up a CNAME record from your tracking domain to with your DNS service provider. Please note that “customer” is not a placeholder and remains unchanged.

3. Create a certificate for this subdomain and send it along with the private key. The certificate should be valid for at least one year. We recommend a multi-domain certificate with a 2-year term and 2048-bit key length. Wildcard SSL certificates are not supported for integration.

Attention: The transmission must only be strongly encrypted via separate channels. The certificates and keys should only be uploaded to the following two folders in our cloud:

For the certificates:

For the private keys:

The files can be uploaded securely via these folders. As an additional security level, we recommend encrypting the files. For this purpose, 7-zip can be used, for example. You can find instructions on how to encrypt with 7-zip here. Both files (certificate and private key) can be protected with the same password. We recommend to communicate the password only by telephone.

4. adapt your etracker tracking code on your website by

a) adding the following variable to the parameter block:

var et_proxy_redirect = '//';


b) adjust the src attribute to your tracking domain, e.g.:


Please note that a new certificate should be submitted at least one month before expiration.
