The Performance Tracking tool gives you the option to segregate your keywords into groups.
Once all the keywords have been added to your project, you can segment them into groups. You need to click Add and then select Keyword Group. You can then add a keyword Group and move all keywords of your choice into it.
Select the keywords you wish to add into the group, and at the bottom of the page select Select and Action and then Move to Group and select the Destination Group you’d like to move them into from the drop down list.
