50 things I believe about data

A new trend is rising in the analytics and web marketing community! Lists of 50 things you believe about your industry. My inspiration was the following great lists of “50 things I believe…” from Tim Wilson and Cory Underwood:

(Bonus: It’s also worth checking out this article from Jan Exner, which breaks down Tim Wilson’s list into more detail.)

The list below was created based on my experience working in digital analytics projects since 2008 and from numerous conversations I had while organizing the Digital analytics meetup, Thessaloniki since 2017.

The list

In no particular order:

  1. Have detailed understanding of data before reporting on them
