Simply Measured Engineer here! To clear up your question, we define Brand Engagement as:

"The total number of likes, comments, and shares on Brand Posts that occurred during the reporting period." -- SM Help Docs

I'm guessing that it wasn't spelled out in the post because Contently and our original article are primarily aimed at Social Media Marketers, and the definition is fairly well established.

While the definition is established, we've published some articles that dig deeper into engagement:

and looking at a more relative number: http://simplymeasured.com/blog/2014/02/19/facebook-engagemen...
