I'm new to Adwords Editor.... I use the keyword grouper to take 1000 or so keywords from one ad group and divide them up. Everything goes fine. Then I try to post changes, and nothing posts. All my new ad groups have a little red circle icon next to their folder name. What does this mean?
Open the parent campaign of the circled ad groups and then switch to ad group view. Click the adgroup and it will tell you what's the error. I think you forget to set the daily maximum CPC bid or forget to give them text ads.
