I've been adding keywords to an Adwords campaign via the Editor with no problems. Changes have been instant. But I have now grouped like keywords together in Adwords Editor and created 17 new Ad Groups. I posted the changes to my campaign but 30 minutes on and they still havent appeared. Can doing this sometimes take a bit of time or has something perhaps screwed up? Ta EDIT: Have worked it out. The changes were not originally posted. I had to add max cpc for each new ad group. Having done that, the posting is complete and all new groups are now visible.
