Narrowcasting push ads for affiliate offers can be effective, but several drawbacks limit their success. First, overly specific targeting reduces audience reach, which can lower potential conversions. Push ads can also be perceived as intrusive, leading to ad fatigue or user disengagement. Additionally, users receiving repeated affiliate offers may become skeptical, reducing trust in both the advertiser and the brand. High competition in affiliate marketing also drives up costs while diminishing ROI. Compliance issues may arise if push notifications violate user consent or privacy regulations. Lastly, poorly matched offers due to inaccurate targeting can damage brand credibility and reduce overall campaign performance. Balancing precision and scale is critical to avoid these pitfalls in narrowcasting affiliate push ads
