Couldn't add, edit, or remove a keyword. This is usually caused by missing data (ad group, client account, or keyword text) or by a Google policy rejection.

How to fix it:

  1. Check that the ad group and account are selected and that the keyword text is valid.
  2. Resubmit.

If Google rejects it for policy reasons, adjust the keyword. If the error is generic and persists, contact support and include the ad group and the keyword text.
