How to Reduce Wasted Spend in Category vs ASIN Targeting
← Back to Amazon Category Targeting vs ASIN Targeting: How to Compare Performance
Quick answer
Wasted Amazon Ads spend in category and ASIN targeting is reduced by treating each targeting type as its own search term stream. Sellers review search term reports routinely and add negative keywords or lower bids for terms that underperform inside each group. This prevents broad category matches and specific ASIN targets from hiding underperforming queries in a blended view. Regular cleanup keeps budgets focused on placements that support the account's ROAS targets.
The most common cause of wasted spend is not the targeting type itself, but the search terms each type picks up. Category targeting can pull in high-volume, low-intent queries, while ASIN targeting can pay for placements that never convert. The fix is to view those streams separately and make small, routine adjustments.
Track category and ASIN performance separately
Start by pulling performance by targeting expression, not by campaign name alone. Category campaigns and ASIN campaigns often share line items, so a blended view hides which side is leaking. In the Amazon Ads Dashboard by Todoza, review ROAS, ACoS, and wasted spend side by side for category and ASIN groups.
- Pull separate search term reports by campaign or targeting expression.
- Compare impressions, clicks, orders, and ACoS within each targeting group, not against the whole account.
- Flag terms with high clicks and zero or very few orders.
Decide between negative keywords and lower bids
Once you isolate the underperformers, decide whether a search term should be blocked or simply made cheaper. Irrelevant terms that never lead to orders are better handled as negative keywords. Relevant terms that occasionally convert but miss your target ROAS are usually better served by a lower bid. The Amazon Negative Keyword Tool by Todoza can help classify those terms from campaign-specific performance signals. It does not apply changes automatically, so you keep control over final decisions.
- Add negatives for clearly irrelevant searches in category targeting.
- Lower bids on high-click, low-conversion terms that still have purchase intent.
- Keep limited-data terms visible until they have enough clicks for a decision.
When this matters most
Waste reduction matters most when category targeting is producing high impressions but few orders, or when ASIN targeting is dominated by a small number of expensive placements. In those cases, cleaning the search terms often changes the next optimization conversation. Instead of pausing a whole targeting group, you can keep the productive parts and only remove the spend that does not pull its weight.
