Two questions:
1) I paused a lot of keywords. Is there any difference, pros/cons for performance history, between Pausing and Deleting? And what about leaving keywords as "Inactive for Search" or should I just pause those too?
2) I have some keywords that are just low volume. Meaning very few impressions, sometimes only 20 per day. A lot of these have 0 clickthroughs therefore I have a 0% click through rate. Should I pause these because this looks like its poor performing? Or is it just low volume? Would you pause these, or would you let them ride to try to pick up some long tail clicks?
Any insight would be very helpful.
Thank you!
