I come from an era where DM's had nothing to do with direct marketing and I often find myself in long meetings wondering what a wide range of digital agency acronym's actually mean. If we're not deciding on KPI's then we're worried about CRM or how much to spend on PPC. I've been in the online world for long enough to really know better, but it often feels like they are made up on the spot to confuse clients and the meanings differ wildly from agency to agency.

It's quite tricky not to look like a bit of a plum when you have to stop a meeting and ask what something means that seemingly everyone else knows in the room. It's like forgetting someone's name who you've met before – the longer the conversation goes on the worse it gets and the harder it is to ask the question.

I did a bit of a Google search and to help you out, as stolen from this site, here's a list of 60 common digital agency acronyms ... feel free to mail me any ones I've missed off or make up any ones I can use in meetings to sound clever.
