How Are Amazon Ads Threshold Alerts Set?
← Back to Amazon Ads Performance Alerts: Absolute Thresholds vs Percentage Changes
Quick answer
Amazon Ads performance alerts are typically configured using one of two threshold types: absolute values or percentage changes compared to previous periods. An absolute threshold is a fixed number for a metric such as total spend, clicks, or ROAS. A percentage-change threshold reacts to relative movement over time, such as a 20% week-over-week drop in sales. The exact setup varies by tool, but the goal is to tailor notifications to the metrics that matter for a specific campaign or account.
The key difference comes down to whether an alert watches a fixed line or a change from recent history. Both approaches have a place, and many teams end up using a combination of the two.
Absolute Thresholds vs Percentage Changes
An absolute threshold is a hard number. You might set an alert when daily ad spend crosses $50, when total clicks pass 1,000, or when ACOS exceeds 35%. The alert does not consider what happened before; it simply fires when that value is reached.
A percentage-change threshold compares periods instead. For example, the tool may alert you when spend is 25% higher than the previous seven days, or when ROAS drops 15% compared to the prior week. This type of alert is more contextual because it reflects momentum rather than a single fixed boundary.
How Tools Let You Tailor Alerts
Most Amazon Ads analytics platforms allow users to select the metric and threshold type for each alert. A new product launch may need an absolute spend cap to prevent overspend, while an established campaign may need a percentage-change alert for ROAS decline. The Amazon Ads Dashboard by Todoza supports this by aggregating data from multiple accounts and marketplaces and allowing comparison with previous periods.
That type of historical comparison helps you set thresholds based on real performance instead of picking arbitrary numbers. It also makes it easier to adjust alerts as accounts scale or seasonal shifts change the normal range.
When This Matters
Threshold setup becomes more important as campaigns multiply. Without clear alerts, one underperforming keyword or one market can quietly consume budget. A mix usually works well: absolute thresholds catch overspend limits, and percentage-change thresholds catch sudden declines that still fall within a reasonable absolute range.

Thresholds are most useful when they match the way you actually manage Amazon Ads. Whether you lean on fixed limits, percentage shifts, or a combination, the setup should reduce noise and surface the changes worth investigating. That principle sits at the center of the broader absolute versus percentage alert comparison.
