The new digital era has enabled brands to selectively target their customers that may potentially be interested in their brand or based on previous browsing interests.

The General Data Protection Regulation (GDPR), which took effect on May 25, 2018, is a set of regulations governing the use of personal data across the EU. This is forcing some affiliates to obtain user data through opt-in consent (updated privacy policies and cookie notices), even if they are not located in the European Union.
