Cross-Campaign Cannibalization Checker
Paste keywords across campaigns, find overlaps and conflicts
Imports a multi-campaign keyword export (campaign, keyword, match type) and surfaces every place you are bidding against yourself — broad in one campaign eating exact in another, identical exact-match in two campaigns, near-duplicates with different bids.
- Paste a CSV with columns campaign, keyword, match_type.
- The checker normalizes match types and runs an N×N comparison.
- Output: a conflict list grouped by severity — exact-vs-exact (highest), broad-eats-phrase (high), near-duplicates (medium).
- Each conflict shows both campaigns and a suggested resolution.

Why this exists
Cannibalization is the audit finding nobody surfaces because it requires looking across campaigns. At an agency with 30+ accounts, doing this manually is impossible; this tool turns it into a five-minute task.
Frequently asked
What is keyword cannibalization in Google Ads?
Cannibalization is when two campaigns or ad groups bid against each other for the same query. It typically happens when broad-match in one campaign overlaps exact-match in another, or when the same exact-match keyword exists in two campaigns. The result: you pay yourself, your CPCs go up, and Smart Bidding sees mixed signals.
How do I detect cross-campaign cannibalization?
Export keywords with their campaign and match type, then look for the same keyword in different campaigns or for broad-match keywords whose tokens appear as exact in another campaign. This tool automates that comparison and ranks conflicts by severity.
How do I fix cannibalization once detected?
Three options: (1) consolidate the keyword into one campaign and pause it elsewhere, (2) add it as a negative on the broader campaign so traffic flows to the more specific one, (3) accept the overlap if both campaigns serve genuinely different intents (rare). The tool suggests one of these per conflict.
