I created a campaign that targets two sites. Both have sufficent CPC levels for the market. One site has yet to display any ads, the other only displayed a few thousand though the site receives 100k pageviews.
The site that displays, has had good response for content network. 23 clicks over 4240 impressions for .54 CTR. yet the ads don't display most of the time.
