I guess now that I think about it, Google may not want to encourage this so maybe it's not possible. There are about 45 ad groups in this campaign and I am just trying to avoid having to manually setup his entire account. Anyone know if this is possible?
Then, just sort the campaigns, ad groups, at texts, keywords, and negative keywords apart in the CSV file - and upload each section individually using the "Make Multiple Changes" tabs. From there, you can paste the data you'd like to upload.
Disclaimer: I've just noticed that there's another option called "Export for Sharing" within Adwords Editor... it sounds intriguing, but I've never used it. Has anyone else? Does this offer an easier solution thatn the one I've outlined?
