Investigating analytics vs database count gaps
WHAT IT TESTS: Data-quality debugging. OUTLINE: Causes include ad-blocker loss, differing identity logic, timezone mismatches, filtering, and pipeline delay; investigate by aligning definitions and tracing one user. RED FLAG: Trusting one source blindly.
WHAT IT TESTS: Whether you can systematically reconcile two data sources rather than trust one. ANSWER OUTLINE: Causes: client-side event loss from ad blockers and network failures, different definitions of a user, timezone and date-window mismatches, bot or internal filtering, sampling, and ETL latency. Investigate methodically: align metric definitions and windows first, trace a single known user through both systems, then quantify each gap. RED FLAG: Declaring the database the truth without checking that both define users the same way.
