How to Reduce Amazon PPC Wasted Spend

The fastest way to cut wasted Amazon PPC spend is to negate irrelevant search terms from your Search Term Report. Most accounts I audit waste 8–15% of total ad spend on search terms that will never convert. That's $800–$1,500/month on a $10k account and $4,000–$7,500/month on a $50k account — sitting in your data right now.

What most people get wrong about this

Wasted spend hides in five places. I check them in this order because the first two typically account for 70% of the waste.

What I would actually recommend

1\. Irrelevant search terms (biggest source). Auto and broad campaigns trigger on terms Amazon thinks are relevant but aren't. On one account I reviewed, 30% of non-branded search terms were genuinely irrelevant — generating impressions and clicks but zero conversions. Fix: weekly Search Term Report review plus negative keywords.

2\. Branded overbidding. Most accounts bid too aggressively on their own brand name. If you're paying $1.50/click on branded terms when competitors are bidding $0.40, you're paying 3x what's needed. Fix: reduce branded bids 15–20% and test whether impression share holds.
