You have created some new ads, submitted them to AdWords only to find that they have been given a status of "Under Review".
Normally, ads are reviewed and approved rather quickly, however you can often find yourself in a situation where your ads are stuck under review for weeks.
Because of the number of accounts that I manage, I can run into this situation several times in a week. I have created a template email that usually helps to resolve the issue.
It seems like this is a common problem for others as well, as Google have now created a new form specifically for this issue. Here is what they have told me:
"For future reference, if your ads have been under review for more than 3 business days, you can send your ad review request to our team directly via this link: http://adwords.google.com/support/aw/bin/request.py?contact_type=approval_request "
I have yet to use the form. Hopefully it will work even faster than my emails.
