A WebmasterWorld thread has an advertiser who is speculating based on specific referrer URLs he spotted in his analytics software that Google AdWords representatives have specialized internal tools to quickly and effectively build campaigns for AdWords advertisers.
Meaning, the Google representatives have internal tools that may or may not give them an upper hand when creating campaigns for advertisers.
One person said:
My Google rep. is building a new AdWords Campaign for me and I noticed in my Analytics a referrer URL that looks like Google's own internal Campaign Builder tool.
Honestly, I'd be surprised if Google representatives didn't have specialized tools that gave them a bit more insight and details versus what they give to the public. Which may be why some are finding Google representatives pretty good at building campaigns.
