I just started a new campaign and have enabled both the search and content network. The Ads are showing on the search network but I'm getting 0 impressions on the content network. I've ran these same keywords before and had extensive impressions/clicks on the content network before also. Moreover, I know it's not a budget issue because there aren't that many other Ads running (and thus my Ad would be high enough to show given my bid amount).
It's just it just was never started. Any ideas?
