Here is some data:

AdGroup running for about 1 month.
82 total keywords

29 keywords not showing any impressions
-- My ad shows for 8 of these on Google when I enter the keyword.
-- Of the remaining 21, some show ads for other advertisers or no ads at all.

I understand that Google wants to pare down some of the dead wood keywords, but I question the shortness of the time period involved. 3-6 months without an impression sounds fair, but a month or less?

I'm caught between "broad matching" that doesn't truly broad match and longer keyword phrases which are deactivated for low impressions. I'm trying to expand my Google spending, but it's turning into more and more work.
