In my previous role as a Marketing Analyst, I encountered a data quality issue while analyzing the performance of a digital marketing campaign aimed at increasing customer engagement. The campaign metrics initially indicated a significant increase in engagement, but upon further investigation, I discovered discrepancies that raised concerns. To troubleshoot the issue, I employed a multifaceted approach. First, I conducted an extensive review of the data collection process, examining the tagging implementation on our website and mobile app. Through this analysis, I identified that the incorrect implementation of event tracking tags had caused the data quality issue. To address this, I coordinated with the development team to rectify the tagging errors and reconfigure the event tracking setup.
