I just started to try and use the Google Content Network and watched all the videos from Google and set up themes in different ad groups as they suggest. The problem i am having is that to test a campaign, i direct link in the destination url to see if it's worth building a website for the campaign. I get a lot of impressions for a day or so then the traffic just stops coming. I thought it may because of the direct linking, so i built a quick Blogger blog for a landing page and same thing happens. I don't get a message from Google that anything is wrong, just no more traffic. Anyone know what i could be doing wrong?
