...Diagnosis tool: your ad does not show because the CTR is too low.
Hmmm, HitProf. Is this a keyword that has been around for a very long time (say since before the switch to quality based minimum bids), but with no impressions ever? If so, deleting it and re-entering it may be the right thing to do.
Or is it a new keyword of a potentially 'sensitive' nature? Then it may need to be reviewed/approved.
Bottom line, you may want to contact AdWords support and have them take a look.

It is from (just) before the switch. If I remember well a lot of them started out as on hold immediately. Most got better after a whole. We have hundreds of these in this account alone.
Deleted keyword & re entered it again. Same result so far. I'll try again tomorrow.
Sorry to say, but in my opnion this is a totally needless action. Should have been solved by Google automatically when the new system kicked in. This is one example of the lack of thinking begore going live with changes I guess.
