When I first started working in the internet industry, back in 1874, a colleague said to me that I shouldn’t be daunted by the ridiculous number of acronyms that are seemingly used on a daily basis. I’d learn them in good time, he said. There was no need for panic stations.

Sure enough, I was bombarded with seemingly random three- and four-letter acronyms, from all directions. I hunkered down and gradually learned the most important ones. I’m somewhat allergic to jargon, but sometimes there is no getting around the fact that we need to speak the right language in digital marketing circles. There is only one way to describe ‘real-time bidding’ (RTB), and no amount of Plain English is going to improve that kind of phrase.

We used to have a glossary on a much older version of Econsultancy.com, but that’s long since vanished, so I thought I’d compile a handy cut-out-and-keep guide to help newbies to get up to speed with the lingo.

So here is a list of the most common acronyms that every digital marketer should know about. I think they cover most bases, though no doubt I have missed out a few obvious ones (by all means add them in the comments area below). Some of these are very much filed under ‘marketing’, whereas others lean more towards ‘tech’ (but are included as you are likely to cross their paths at some point). For the purposes of brevity I shan’t define each one: that’s what Google / Wikipedia is for.
