Because you can only have a keyword in one ad group at a time, you may want to remove a specific keyword from one ad group and move it into another ad group.
- Go to your Pay Per Click Dashboard/Ad Campaigns Dashboard.
- Navigate to the Keywords tab.
- Check mark the keywords that you want to delete.
- Click on the Actions drop down menu and select Remove.
Reassigning the Deleted Keywords to a New Ad Group
Once you have deleted the keyword you can now assign it to a new ad group by clicking on the red + Add Keywords button from that same Keywords tab.
