Keyword-Level Bid Review
Every keyword is judged on its own figures, not on its campaign's average.
Overview & Capabilities
A campaign holding one keyword at 15% ACOS and five at 90% averages into a single decision, and the one that works is punished along with the ones that do not. SellerSigma imports a targeting report from the Amazon Ads API nightly and reviews each keyword against the same rules it applies to campaigns. A keyword is judged once it has taken at least 2.00 of spend in the review window, a lower floor than the 5.00 used for a whole campaign, because a keyword is only a fraction of its campaign. Keywords below that floor are not judged at all and follow their campaign's decision instead. Every multiplier is clamped between 0.7 and 1.3 so no single review can swing a bid more than 30%, and the resulting bid is held between 0.02 and 100.00.
Key Benefits
Winners Are Not Punished
A keyword performing inside your target ACOS can be raised even when its campaign overall is being cut back.
Losers Are Not Carried
A keyword spending without converting is cut on its own figures rather than hiding inside a campaign average.
Small Accounts Still Get Decisions
The keyword spend floor is 2.00 rather than the campaign's 5.00, so a modest account still receives keyword-level review.
Bounded Moves
Each review can move a bid by at most 30% in either direction, so nothing changes abruptly.
How It Works Step-by-Step
Report Import
A per-keyword targeting report is imported from the Amazon Ads API nightly at 03:00 UTC.
Weekly Review
Every Monday at 04:00 UTC, or on demand, each keyword with enough spend is checked against the rules.
Proposal Drafted
Keyword changes are carried on the same bid proposal as the campaign's, each with the figures behind it.
Applied After Approval
Approve it in Copilot, or let Autopilot approve it, and the new bids are written to Amazon Ads.

Frequently Asked Questions
Is this AI?
No. The bid review is rule-based, so the same figures always produce the same multiplier. Only keyword generation uses an AI model.
What happens to a keyword with almost no spend?
Nothing on its own account. Below 2.00 of spend there is not enough evidence to judge it, so it follows its campaign's decision instead.
Are keywords reviewed in a campaign that is still finding its feet?
No. A campaign diagnosed as stalled or under-delivering is being bid up to gather data, so cutting its keywords in the same proposal would undo that.
