Is it possible to copy an entire ad group? I really dont want to have to make 50 ad groups by hand when 90% of each one is the same.
Use AdWords Editor for that: http://www.google.com/intl/en/adwordseditor/index.html you can copy/cut and paste several adgroups or entire campaigns in seconds using just a Ctrl-C & Ctrl-V
Micromag is correct, Adwords Editor is the easiest way to do it. Or within the Tools menu, there is a function called "Copy or Move Keywords and Ad Text" & "Advanced Search and Editing" which may be of help. But definately download Adwords Editor, its a real time saver. http://www.google.com/intl/en/adwordseditor/index.html
Thanks for the tip on Adwords Editor, I've been copying ad groups by hand for a long time, really frustrating.
