Common Issues We Find

- Email addresses appearing in page URLs
- Referral spam inflating traffic numbers
- Missing User-ID for cross-device tracking
Why This Matters
Decisions based on bad data are worse than gut feelings. Data quality issues compound over time — a small PII leak today becomes a GDPR violation tomorrow.
