Common Mistakes
- 1 Running experiments that create individual user profiles without analytics consent
- 2 Not distinguishing between functional A/B tests and personalisation experiments in consent settings
- 3 Using the full-stack client-side SDK when server-side or edge evaluation would reduce data collection
Compliance Considerations
Collects visitor identifiers, experiment assignments, and conversion events. Basic A/B testing of UI elements may operate under legitimate interest for site optimisation. Personalisation features that build visitor profiles increase consent requirements. Optimizely Edge can reduce client-side data collection. EU data processing available — verify configuration.
