When troubleshooting a TikTok Ads campaign delivering sub-optimally, what reporting dimension should be analyzed *firstto identify potential issues?

When troubleshooting a sub-optimally delivering TikTok Ads campaign, the *firstreporting dimension to analyze is 'Delivery Status' and 'Performance' metrics segmented by 'Ad Group'. Checking the 'Delivery Status' (e.g., Active, Learning, Limited, Not Delivering) immediately reveals if there are any fundamental issues preventing the ad group from running, such as disapproved ads, bidding problems, or budget limitations. Simultaneously, analyzing core performance metrics like 'Impressions', 'Click-Through Rate (CTR)', 'Cost Per Click (CPC)', and 'Conversion Rate' at the ad group level helps pinpoint *wherein the funnel the campaign is faltering. Low impressions suggest targeting or bidding issues, low CTR indicates problems with the ad creative, high CPC signals increased competition or irrelevant targeting, and low conversion rate points to problems with the landing page or offer. Analyzing delivery status alongside these key performance metrics at the ad group level provides a rapid and efficient way to diagnose the root cause of the underperformance before diving deeper into more granular data.
