Cost overruns in push ads for affiliate marketing can severely impact profitability and campaign sustainability. When ad spend exceeds budgeted limits without a corresponding increase in conversions, return on investment (ROI) declines sharply. Affiliates may struggle to break even, especially in competitive niches where margins are tight. This financial inefficiency can lead to reduced trust from advertisers, lower payouts, or terminated partnerships. Additionally, overextended budgets may limit future marketing opportunities or force cuts in testing new creatives or targeting strategies. Inaccurate budgeting due to cost overruns can also distort performance metrics, making optimization difficult. Ultimately, unmanaged overspending reduces scalability and can jeopardize the long-term viability of affiliate marketing efforts, especially for small or independent affiliates operating with limited resources.
