I was wondering if someone could help - I am in the process of totally re-jigging our adwords campaign (we just started it a couple of weeks ago when we knew nothing!). I am separating all the keywords into separate groups so that the relevancy is high and there are ads to match, just a quick one on this though. Should I separate these by ad groups or campaigns? Will a poor performing adgroup in terms of CTR affect the whole campaign or just that ad group - I am looking about 10 different groups whether that be campaigns or ad groups! Can anyone help? Just need to know before I actually get on and do it! Thanks
