Hi, This is not to ask any advice but rather to tell you what happened to my account. I recently got slapped and it was not the first time so I came to the conclusion that I should change my account. So I changed my account and started up again. I made several campaigns according to the keywords, but the same landing page. For 3 weeks after that, I got enough impressions and hits(700-800/day). I was glad I changed my account. Then, a week ago or so, all of a sudden, ALL the impressions were gone. ZERO impressions in every single campaign. I turn the serch on to see how the QS of the keywords are. And to my surprise, they were still all 7-9. So I thought it wasn't slapping. But I thought it was strange and couldn't figure out what was happening. I finally decided to contact adwords by e-mail and they e-mailed me back saying my qs is bad now. I put my search on to make sure, and my qs is still good (So ads show up on search somehow).... It seems they have a different standard of QS for content. FYI my site is "e-book" style, long landing page, but not selling an e-book. (actually selling some seminar "CD"s in mp3 format, it is my product, my copyright) I know Google hates long landing pages but my competitors have similar landing pages and seems keep showing so I don't know why mine keep getting slapped! Anyway hope it helps as information, and also appreciate if you have any feedback on this.
Oh, I forgot to mention (but I assume you got it) that I used content network only.(Turned off search)
