As marketers, we focus a lot on the day to day activities to make a brand successful - to make a brand that sells.
However, sometimes it helps to realize that we are apart of a larger system in advertising at times and to understand those systems.
What does Facebook need and want?
How does the system work and how does it distribute media?
What are the economics of advertising?
Understand these macro dynamics are just as important as understanding how to make the brand itself.
Don't be a marketer that is just a piece in a system - be one that understands the systems and knows how to thrive in them.
