Explaining all the marketing acronyms you were too afraid to ask about.

Listen, we’ve all been there. Sitting in a strategy meeting, a new business pitch, or just around the office, when the conversation turns to three simple letters. You know a lot of business acronyms, but this one, you’ve never heard it in your life.

“Are we hitting our KPIs with our current DSP? What is the CPM?”

So now you’re faced with the age-old dilemma: ask what it means at risk being seen as uninformed, or tread water through the conversation the best you can and try to pick up context clues.

Acronyms are a useful tool in a modern industry. They make written communication easier and provide a common language for people to communicate with colleagues and clients—provided you can actually walk the walk. So here’s a glossary of commonly-used marketing acronyms. Our hope is that you can avoid those dreaded meeting moments, and maybe impress a colleague or two with your newfound knowledge.
