1. Go to one of your domains and visit the keyword tab.
2. Click "+ Add keywords" in the top right corner.
3. Enter the keywords you wish to add in the left box and to the right attach the groups associated with the keywords to be added:
4. If you don't want all keywords to belong to a group, use the following pattern to assign a keyword to the group:
my keyword | keyword group
my fruit | fruit group
"my keyword" will now belong to the group "keyword group" and "my fruit" will belong to "fruit group". In case multiple groups should be assigned separate each group using |.
