My administrator has entered about 250 Adgroups into the same Campaign on the Adwords Editor. When trying to upload the changes, I got the error saying I have exceeded the limts of my account. Now to my mind, it is probably the number of Adgroups in the one Campaign. Is there any way to move these Adgroups into another Campaign or will I just have to delete them and start again?
This just happened to me a few weeks back. You're exceeding your account size, moving to a new campaign won't help. You'll need to call AdWords support and see if they'll up the limits on your account.
If you do need to move adgroups to another campaign, you can just cut and paste them from within the adwords editor app.
