What happens if your ads manager can't reach your ROAS floor?

When an ads manager cannot reach the Return on Ad Spend (ROAS) floor, the likely outcome is that delivery may stop and the budget may not be fully spent. This situation arises because the ad platform's algorithms aim to optimize performance. If the ads consistently fall below the expected ROAS threshold, the system may reduce or halt ad delivery to prevent inefficient spending.

This behavior aligns with the goal of maximizing advertising effectiveness by ensuring that budget allocations result in profitable outcomes. When the set ROAS floor is not met, it indicates that the ads are not generating the expected revenue relative to the amount spent, so the platform prefers to stop serving these ads rather than continue investing in underperforming campaigns.

In contrast, other options suggest actions like pausing ads, automatically increasing spending, or providing a larger budget, which do not align with the ads manager's approach to optimization and resource allocation in response to performance metrics.
