When should you troubleshoot delivery?

Troubleshooting delivery is crucial at specific times to ensure that a digital marketing campaign meets its goals effectively. The selected choice indicates that troubleshooting should occur when the campaign is pacing but not filling key performance indicators (KPIs) or when the campaign is not delivering at all.

This is correct because early detection of issues enables marketers to make necessary adjustments to the campaign in real-time. If a campaign is pacing but failing to meet KPIs, it suggests there may be underlying problems such as targeting mismatches, ineffective creative, or inadequate budget allocation for the desired reach and frequency. By addressing these issues promptly, marketers can optimize the campaign to better align with objectives and improve overall performance.

In contrast, waiting until the campaign ends to troubleshoot would be less effective because it prevents any opportunity for adjustments while the campaign is live, potentially leading to wasted ad spend and poor results. Similarly, troubleshooting only when the cost exceeds the budget may overlook critical performance issues that affect the campaign's success. Conducting analysis during campaign phases is important but may not provide the immediacy needed for proactive troubleshooting that could positively impact ongoing efforts.
