Which are signs of creative fatigue in TikTok ads? (Select 3)

Creative fatigue occurs when an audience becomes overexposed to an ad, leading to diminishing returns. A decrease in likes, comments, and shares over time directly indicates reduced engagement, a key sign of fatigue. A reduction in impressions happens because TikTok's algorithm detects lower engagement and prioritizes newer, more engaging content, thus showing the fatigued ad less frequently. A decrease in click-through rates (CTR) is another clear indicator, as it shows fewer people are compelled to click on the ad, suggesting they've seen it too often or it no longer captures their interest. Conversely, a decrease in cost-per-action (CPA) is generally a positive trend, indicating efficiency, not fatigue.
