Stop your Amazon campaigns from bidding against each other.

Search Term War Eliminator is a free analyzer built by Lynx Media that surfaces every search term where two or more of your Sponsored Products campaigns are competing — driving up your own CPCs by bidding against yourself. Drop in your search-term report; the tool maps the overlap and tells you which campaign should win the term.

Built for $1M+ FBA brands with sprawling campaign structures (auto + manual + branded + non-branded + product-targeting). The bigger your structure, the more cannibalization you're paying for.

How it works

Download your Amazon Sponsored Products Search Term Report (last 60-90 days).
Drop the CSV into the tool. Everything runs locally in your browser — nothing uploaded.
The tool groups by search term, flags terms appearing in 2+ campaigns, and ranks the worst offenders by total wasted spend.
Export the conflict list as CSV. Add losing terms as negative keywords in the campaigns that should NOT win them.

Use cases

Post-merger campaign cleanup — when a brand has been managed by 3 different agencies in 3 years, the campaign overlap is usually massive.
Brand-defense audit — make sure your branded campaigns aren't getting outbid by your own auto campaigns on your own brand terms.
Bid-inflation diagnosis — when CPCs creep up and you can't explain why, internal cannibalization is often the answer.

Frequently asked questions

What counts as "cannibalization"?

Any search term that appears across 2+ campaigns where both campaigns are spending real money. Both campaigns enter the same auction; Amazon serves whichever bid wins; you pay the inflated price.

Is this really free? Where's the upsell?

The tool is free, no email gate. If you want our team to run the audit + restructure the campaigns, that's our paid agency service. The tool itself shows you the same data we'd use in step 1 of any engagement.

How is this different from a regular search-term audit?

A regular audit looks at terms vs. performance. This tool looks at terms vs. your other campaigns. Different question, different answer. Most teams miss it because Seller Central doesn't surface it natively.

Does my report data leave my browser?

No. The CSV is parsed and analyzed locally with JavaScript. Nothing uploads.

What about Sponsored Brands or Sponsored Display?

This tool focuses on Sponsored Products search-term reports. SB/SD cannibalization is a separate analysis. Book a free Profit-Leak Audit if you want all three surfaces mapped.
