Lists every enabled keyword with zero impressions over the lookback window, grouped by campaign — the dead weight that clutters audits and sometimes hides real problems like sub-first-page bids or negative conflicts.

Uses Claude AI to analyze your search terms and recommend negative keywords with clear reasoning. Each term is evaluated for business relevance, intent, and conversion potential — then exported to a Google Sheet with actionable suggestions.
Finds brand search terms leaking into non-brand campaigns (inflating their stats and misleading Smart Bidding) and generic traffic riding in brand campaigns — with the misrouted spend quantified.
Measures how much of your exact-match spend actually flows through close variants and lists the zero-conversion variants — the most surgical negative keyword candidates in the account.
Reads negative keywords and placement exclusions from a Google Sheet and syncs them to multiple campaigns via shared negative keyword and placement lists. Optionally filters to campaigns with a specific label.
Quantifies spend on search queries containing competitor names, with conversion performance and a period-over-period trend — whether competitor bidding is your strategy or your broad-match accident.
Shows what your Dynamic Search Ads decided on their own: waste queries to negate, the landing pages absorbing DSA spend, and converting queries to promote into real keywords.
Zombie Keywords pulls every enabled keyword that recorded zero impressions during the lookback window (90 days by default — a fair trial) and groups the result per campaign with sample keywords. Zombies are rarely dangerous by themselves, but hundreds of them slow every audit, distort keyword counts, and often point at a real cause worth fixing: bids below first page, negligible search volume, or keywords silently blocked by your own negatives.

=== Zombie Keywords (0 impressions during LAST_90_DAYS) === Total zombies: 214 Generic — Broad: 148 zombie keyword(s) - "artisanal shoe repair kit" (EXACT) in Repair Kits - "bespoke sneaker restoration" (PHRASE) in Restoration ... and 138 more Brand — Exact: 66 zombie keyword(s) - "brandname outlet coupon 2019" (EXACT) in Coupons ... and 56 more Email sent to you@example.com
Report-only: nothing is paused automatically — zombie lists deserve a human look because a zero-impression keyword can also mean a seasonal term or a brand-new addition. If entire ad groups are zombies, check bids and run a negative keyword conflict check before bulk-pausing.
