In the Adwords circles, there’s something call the Google stupidity tax. The reason why its named that is because advertisers don’t really know what they’re doing when it comes to Google Adwords. Google’s interface is beautifully designed, it “leads” you to click this and that, until you’re done, or at least its what you think.
When I first started using Adwords many years ago, I blamed Google for misleading advertisers. They just seemed to be spending budgets so fast and nothing in return. At what point does the advertiser and practitioner take responsibility?
