Negative keyword exclusions can be applied at different scopes in an account. A shared or account-level list can save work, but one broad rule may affect campaigns with different audiences, intent, and objectives.
Give each exclusion a clear reason
Record the query or concept being excluded, the business reason, the campaigns in scope, and the date reviewed. An exclusion should resolve a genuine mismatch, legal concern, or confirmed source of waste.
Distinguish a clearly irrelevant query from a research query that may have value earlier in the buyer journey. Not every nonconverting visit is unwanted.
Check scope and conflicts
Before applying a shared list, compare its terms with active campaign themes, brand names, product language, and competitor rules. Search for collisions with valuable keywords or required regional terminology.
Use a narrower campaign-level exclusion when only one campaign has the mismatch. Avoid duplicating overlapping lists without understanding precedence and maintenance ownership.
Validate after a change
Review search-term reporting for lost relevant demand and compare qualified outcomes, not only click volume. Annotate the application date and affected campaigns.
Set a review date for temporary exclusions and remove entries that no longer fit. A list that grows without review can gradually restrict useful coverage.
Maintain governance
Assign an owner, require a second review for broad exclusions, and keep a rollback path. Make the reason legible so future managers do not preserve a rule without context.
