In the past I have usually just paused old campaigns that I no longer want to run in adwords. (same thing with keywords).
Whether they were underperforming or lost a test scenario or expired, it really didnt matter. I even do this with keywords.
However, now as some of my accounts have aged, I am getting a cluttered dashboard with many paused campaigns. I am about to clean up some of them, however I am curious how google views a paused campaign or keyword.
It is my understanding that the overall CTR of your account and campaign can effect your individual ads. Does a poorly performing paused campaign effect your overall performance?
What about a poorly performing deleted campaign or keyword?
Is there any information about this anywhere?
What are the pros and cons of pausing vs. deleting campaigns and keywords?
Thanks in advance.
