Overview

Negative keywords let you exclude search terms from your campaigns and help you focus on only the keywords that matter to your customers. Better targeting can put your ad in front of interested users and increase your return on investment (ROI).

• Add Negative Keywords
• List Negative Keywords
• Update Negative Keywords

Notes

• You can add negative keywords with the negativeExact and negativePhrase match type.
• You can enable, disable (pause), and archive negative keywords.
• This feature applies only to Sponsored Products manual and auto campaigns using a fixed bidding strategy. Negative keywords are not currently supported for Dynamic Bidding or Target ROAS campaigns.
• The limit of 500 negative keywords per ad group applies cumulatively across both negativeExact and negativePhrase match types.
• When a campaign transitions from a bidding strategy that supports negative keywords to one that does not, any configured negative keywords are automatically removed. If the campaign is later moved back to a strategy that supports negative keywords, we will attempt to restore the previously saved negative keyword state.
• Negative keywords submitted via the API are normalized before being stored and applied to campaigns. As a result, the keyword value returned in API responses may differ from the exact string submitted in the request.

Negative Keyword Limitations

• Negative keywords cannot exceed 80 characters.
  Keywords longer than 80 characters will return the following error: Keyword Text length greater than 80
• Each ad group supports a maximum of 500 negative keywords.
  Exceeding this limit will return the following error: Cannot add more than 500 enabled negative keywords in an ad group
• A maximum of 50 keywords can be included in a single POST request.
