Google's replies to my email are just stock answers telling me to tick the boxes in campaign settings. Has anyone else had a similar problem or any idea how to fix it? I wondered if I deleted the whole campaign and entered it again would that have any effect?
"Every time you make changes to your ad or if you create a new one, it needs to be reviewed by our AdWords Specialists prior to being shown on our partner sites."
I guess my ads weren't showing for a few days because I made some changes and like most of us the adwords staff have been on holidays for a few days.
So it seems to me - don't change your adwords just before a holiday or they'll go off the partner sites for a while.
