Digital marketing term
Negative Keyword
A Negative Keyword is a term added to a search network campaign to specify which searches an ad should NOT appear for, preventing irrelevant impressions and wasted spend.
Detailed explanation
This list is continuously updated during campaign setup or after reviewing performance data; for example, an advertiser selling a paid product might add the word "free" as a negative keyword to keep budget from being spent on searches without buying intent.
Search term reports are reviewed regularly to identify low-performing or irrelevant queries, which are then added to the negative keyword list. This process has a positive effect on the campaign's overall CTR and conversion rate.
A well-managed negative keyword list directs ad spend toward the right audience, improving performance metrics like CPA and ROAS.
