Client-side vs server-side event tracking
WHAT IT TESTS: judgment on tracking placement. OUTLINE: client captures UI intent but loses data to ad blockers and tampering; server is trustworthy for transactions but blind to UI interactions.
WHAT IT TESTS: whether you can reason about where an event should be measured rather than dogmatically picking a side. ANSWER OUTLINE: client-side captures rich UI signals like scrolls and clicks but is lossy due to ad blockers, network drops, and is user-tamperable; server-side is reliable, secure, and authoritative for transactional events like purchases but cannot see pure UI interactions. Recommend a hybrid keyed by event type and trust requirements.
