I've added two extra keywords just 2 days ago and it says that they're active but it's not active at all. It still says 0 impressions and 0 clicks.Should I contact Google?
Servant, welcome to WebmasterWorld!
I am a bit unsure of your situation - as AdWords campaigns and Ad Groups can be marked as 'active' (which means only that they are not paused or deleted), but keywords themselves are not marked as 'active'.
So I'm not quite sure what you mean.
My guess is that the keywords are of a 'sensitive' nature, and need to be reviewed and approved before they'll run. But that is purely a guess, and contacting AdWords support is always a good idea when you are unsure about something concerning your account. They can take a look at the account in question, and tell you what is going on.
