The principle: garbage data in = garbage AI out, regardless of algorithm sophistication. Three critical quality issues block AI deployment: incomplete event capture, inconsistent schemas, and platform data silos.

  • Ad blockers (31.5% of users globally)
  • Safari ITP (7-day cookie cap)
  • Firefox ETP (enhanced tracking protection)
  • Cookie rejection (10-25% of users in GDPR regions) Combined effect: 30-40% of user behavior never captured. How this breaks AI: Training a recommendation engine to predict which customers will buy Product B after Product A: What actually happened:

  • Actual conversion rate: 35% What client-side tracking...
