Fixed vs. Dynamic Amazon Review Thresholds
← Back to Amazon Search Terms With Spend but No Orders: How to Set a Review Threshold
Quick answer
Review thresholds are the cost or click cutoffs used to decide when an Amazon search term with spend but no orders should be paused, negated, or reviewed. Dynamic thresholds are generally the stronger approach because they can follow shifting conversion patterns, seasonality, and campaign goals. A fixed threshold may still work for very stable accounts, but it often misses early warning signals when search behavior changes or new product types enter the catalog.
A fixed threshold can still work for very stable accounts, but dynamic thresholds are usually the more practical default for Amazon PPC. The right setup depends on how much your search term data changes from week to week and how often you are willing to review it.
When a fixed threshold is acceptable
A fixed threshold is easiest to audit because the rule does not change unless you change it. It can be appropriate for a mature account with a narrow product range, stable ad prices, and consistent weekly search volume.
In that setting, a fixed spend or click cutoff helps keep low-volume noise from triggering unnecessary negative keyword work. The main risk is that the rule becomes outdated as click costs rise or conversion rates shift.
When a dynamic threshold is more useful
A dynamic threshold is better when campaign performance changes often. Seasonal demand, new product launches, promotional periods, and shifting budget priorities can quickly make an old cutoff too high or too low.
Dynamic does not have to mean automated. Even adjusting your threshold weekly based on recent account trends is more responsive than leaving one number in place for months. The goal is to identify search terms that are consistently underperforming relative to the current baseline, not relative to a number set in the past.
How to apply this without overcomplicating it
A practical approach is to use a rolling lookback window and review terms that clear a simple signal. For example:
- Keep the rule simple: base it on spend, clicks, or the number of days with no order.
- Set a review cadence: update the threshold weekly or every two weeks using recent account data.
- Separate new products: add higher tolerance for newly launched items where a lack of orders is normal during the learning period.
This keeps the threshold flexible without requiring advanced automation.
