Revenue in analytics is 15% lower than in the e-commerce backend. Which is a common legitimate cause?
Answer: Ad blockers and consent denial prevent some transactions from being tracked
Client-side tracking misses users who block scripts or decline consent, so analytics under-reports versus server data.
The same transaction ID appears multiple times in revenue reports after users refresh the confirmation page. How do you prevent this?
Answer: Fire the purchase event only once per transaction ID, such as via cookie or de-duplication
De-duplicating on transaction ID stops page reloads from re-sending the purchase.
Campaign traffic shows as 'direct / none' even though links were shared in email. What is the most likely missing element?
Answer: UTM parameters on the email links
Without campaign tagging, email clicks often lack referrer data and are grouped as direct.
A UTM-tagged campaign is split into 'Email' and 'email' in reports. What caused it?
Answer: Inconsistent capitalization in UTM values
UTM values are case-sensitive, so different capitalization creates separate rows.
After adding a filter, historical data looks permanently missing for some traffic. What is the key lesson?
Answer: Filters change processed data irreversibly, so test on a separate view first
Data filters apply at processing time and cannot be reversed, which is why a test view and raw backup view matter.
Sessions split unexpectedly when users move from your main domain to a checkout on another domain. What setup fixes this?
Answer: Cross-domain tracking
Cross-domain tracking shares the client ID across domains so the session remains intact.
Data in a report is flagged as sampled and results differ slightly between runs. Which action best reduces sampling?
Answer: Shorten the date range or use unsampled export or raw data
Smaller queries stay under sampling thresholds, and exports or raw data avoid sampling.
