First, my credentials: Over the last seven years, I have worked a lot of digital marketing agency jobs. I joined the industry doing entry-level research, and many years later I co-founded and helped build an agency of my own. I have worked as a freelance consultant on both the creative and technical sides. And I have directly experienced most aspects of the digital marketing agency world. I have both made and received broken promises.
The symbiotic relationship between brands and their agencies is a complex one, full of jargon and the constant rustle of asses being covered. Agencies make outlandish promises to their clients because the clients essentially ask to be lied-to. The agency doesn't want to get fired, so they tell the client what the client wants to hear. The client often reports to a manager who sets impossible goals. So the client depends on the promises that the agency tells him, so that when accountability rolls-around, there is somebody else to blame.
So what are the most common lies?
