Duplicate Keyword Finder

When the same keyword is active in two of your campaigns, Apple does not show your ad twice — for any given search, one of your entries is selected, typically the stronger bid. The damage is structural rather than a doubled bill: your impressions, taps, and installs for that query are split across two rows in two campaigns. Neither row accumulates enough data to optimize confidently, and any per-campaign CPA comparison involving that keyword is quietly wrong.

The subtler cost is bid escalation and budget misallocation. Two copies at different bids mean the higher bid usually takes the traffic while the lower-bid copy sits idle — or worse, wins during hours when the other campaign’s budget is exhausted, buying the query at a bid you tuned for a completely different campaign goal. If one copy is exact match and the other is inside a broad match or Search Match campaign, your discovery budget is also re-buying a query you already harvested.

The clean rule is one query, one owner. Give the keyword to the campaign whose job matches its role: proven converters belong in your exact match performance campaign with a bid tuned to their own conversion rate; the discovery campaign should then receive that keyword as an exact match negative, which is what actually stops broad match and Search Match from re-entering the auction for it. Deleting the duplicate without adding the negative only half-fixes the problem.

Before deleting anything, check the performance history of both copies. If the “wrong” campaign’s copy has months of conversion data and the “right” one is new, consider moving ownership gradually — negate first, watch that traffic consolidates onto the surviving copy, then remove the loser. Re-run this check after every restructure or bulk upload; duplication is a recurring condition, not a one-time cleanup.
